前言

相信用过工具类的各位仁兄都觉得工具类好用,小弟不才,今天斗胆拿出自己感觉比较顺手的工具类。


1、Activity控制类

  public class ActivityCollector{
      //activity集合
     public static List<Activity> mActList = new ArrayList<Activity>();
    /**
      * 添加Activity
      * 
      * @param activity
      */
     public static void addActivity(Activity activity){
       mActList.add.add(activity);
     }
    }
    /**
      * 移除Activity
      */
      public static void removeActivity(Activity activity) {
       mActList.remove(activity);
     }
    /**
      * 退出
      */
     public static void finishAll() {
        for (Activity activity : mActList) {
          if (!activity.isFinishing()) {
              activity.finish();
       }
     }
   }
}

2、应用市场管理类

  public class MarketUtils {
     // 360手机助手
    public static final String MARKET = "com.qihoo.appstore";
    // 淘宝手机助手
    public static final String MARKET_TAOBAO = "com.taobao.appcenter";
    // 应用宝
    public static final String MARKET_QQDOWNLOADER = "com.tencent.Android.qqdownloader";
    // 安卓市场
    public static final String MARKET_HIAPK = "com.hiapk.marketpho";
    // 安智市场
    public static final String MARKET_GOAPK = "cn.goapk.market";
    // 包名
    public static final String APP_PACKAGE_NAME = "com.*.*";

   public MarketUtils() {
    throw new AssertionError();
}
  /**
    * 跳转到应用市场
    * 
    * @param appPkg
    *            :上传到应用市场上app的包名,不是本项目的包名
    * @param marketPkg
    *            :应用市场的包名
    */
    public static void goToMarket(Context context, String packageName) {
    Uri uri = Uri.parse("market://details?id=" + packageName);
    Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri);
    try {
        context.startActivity(goToMarket);
    } catch (ActivityNotFoundException e) {
    }
}

   /**
     * 启动App
     * 
     * @param context
     */
   public static void launchapp(Context context) {
    // 判断是否安装过App,否则去市场下载
    if (isAppInstalled(context, APP_PACKAGE_NAME)) {
        context.startActivity(context.getPackageManager()
            .getLaunchIntentForPackage(APP_PACKAGE_NAME));
    } else {
        goToMarket(context, APP_PACKAGE_NAME);
    }
}

     /**
       * 检测某个应用是否安装
       * 
       * @param context
       * @param packageName
       * @return
       */
   public static boolean isAppInstalled(Context context, String packageName) {
    try {
        context.getPackageManager().getPackageInfo(packageName, 0);
        return true;
    } catch (NameNotFoundException e) {
        return false;
    }
}
    /**
       * 判断市场是否存在的方法
       * 
       * @param context
       * @param packageName
       *            应用市场包名
       * @return true or false
       */
  public static boolean isAvilible(Context context, String packageName) {
    final PackageManager packageManager = context.getPackageManager();// 获取packagemanager
    List<PackageInfo> packageInfo = packageManager.getInstalledPackages(0);// 获取所有已安装程序的包信息
    List<String> NameList = new ArrayList<String>();// 用于存储所有已安装程序的包名
    // 从packageInfo中取出包名,放入NameList中
    if (packageInfo != null) {
        for (int i = 0; i < packageInfo.size(); i++) {
            String pn = packageInfo.get(i).packageName;
            NameList.add(pn);
        }
    }
    return NameList.contains(packageName);// 判断pName中是否有目标程序的包名,有TRUE,没有FALSE
}
 } 

3、Toast工具类(不建议使用,请看另外一篇Android 自定义Toast,并且勘误Android工具类里面的ToastUtils

  public class ToastUtils {~
   public static Toast toast;
   public static boolean isShow = true;

   private ToastUtils() {
    // 不能被实例化
    throw new UnsupportedOperationException("cannot be instantiated");
}

    public static void showToast(Context context, String message) {
    if (toast == null) {
        toast = Toast.makeText(context, message, Toast.LENGTH_SHORT);
    } else {
        toast.setText(message);
    }
    toast.show();
}
/**
 * 屏幕中间位置显示短时间Toast
 * 
 * @param context
 * @param msg
 */
public static void ToastShortCenter(Context context, String msg) {
    if (isShow) {
        if (context != null) {
            Toast toast = Toast.makeText(context, msg, Toast.LENGTH_SHORT);
            toast.setGravity(Gravity.CENTER, 0, 0);
            toast.show();
        }
    }

}

/**
 * 屏幕中心位置长时间显示Toast
 * 
 * @param context
 * @param message
 */
public static void ToastLongCenter(Context context, String message) {
    if (isShow) {
        if (context != null) {
            Toast toast = Toast.makeText(context, message,
                    Toast.LENGTH_LONG);
            toast.setGravity(Gravity.CENTER, 0, 0);
            toast.show();
        }
    }
}

/**
 * 自定义显示Toast时间
 * 
 * @param context
 * @param message
 * @param duration
 */
public static void ToastShow(Context context, String message, int duration) {
    if (isShow)
        Toast.makeText(context, message, duration).show();
}
}

4、KeyBoardUtils

  public class KeyBoardUtils {

public KeyBoardUtils() {
    throw new AssertionError();
}

/**
 * 打卡软键盘
 * 
 * @param mEditText
 *            输入框
 * @param mContext
 *            上下文
 */
public static void openKeybord(EditText mEditText, Context mContext) {
    InputMethodManager imm = (InputMethodManager) mContext
            .getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.showSoftInput(mEditText, InputMethodManager.RESULT_SHOWN);
    imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,
            InputMethodManager.HIDE_IMPLICIT_ONLY);
}

/**
 * 关闭软键盘
 * 
 * @param mEditText
 *            输入框
 * @param mContext
 *            上下文
 */
public static void closeKeybord(EditText mEditText, Context mContext) {
    InputMethodManager imm = (InputMethodManager) mContext
            .getSystemService(Context.INPUT_METHOD_SERVICE);

    imm.hideSoftInputFromWindow(mEditText.getWindowToken(), 0);
}
}

5、AES工具类

  public class AESUtils {

// 密钥算法
private static final String KEY_ALGORITHM = "AES";
// AES/CBC/PKCS7Padding 分别对应 加密||解密算法、工作模式、填充方式
private static final String CIPHER_ALGORITHM = "AES/CBC/PKCS7Padding";
// 定义自己的秘钥
public final static String SECRETKEY = "A9e4/vnQTrKF6otAGbM6zGsulKEL7b3x";
// 位移量
public final static String DISPLACEMENT = "9mg+!7ed8b36*w`X";

/**
 * 获取KEY
 * 
 * @return
 * @throws Exception
 */
private static byte[] getKey() throws Exception {
    return SECRETKEY.getBytes(Charset.forName("UTF-8"));
}

/**
 * 加密
 * 
 * @param toEncrypt
 *            文本
 * @return
 * 
 *         加密返回数组
 * @throws Exception
 */
@SuppressLint("TrulyRandom")
public static byte[] Encrypt(String toEncrypt) throws Exception {
    // 秘钥
    Key secretKey = new SecretKeySpec(getKey(), KEY_ALGORITHM);
    // libs中bcprov的支持,bouncycastle支持 64 位密钥
    Security.addProvider(new BouncyCastleProvider());
    Cipher cipher = Cipher.getInstance(CIPHER_ALGORITHM);
    // 获取位移,并初始化
    final byte[] data = DISPLACEMENT.getBytes();
    IvParameterSpec mIvParameterSpec = new IvParameterSpec(data);
    // 用 iv 初始化
    cipher.init(Cipher.ENCRYPT_MODE, secretKey, mIvParameterSpec);

    final byte[] mEncrypted = cipher.doFinal(toEncrypt.getBytes(Charset
            .forName("UTF-8")));

    final byte[] mSpecEncrypted = new byte[data.length + mEncrypted.length];
    System.arraycopy(data, 0, mSpecEncrypted, 0, data.length);
    System.arraycopy(mEncrypted, 0, mSpecEncrypted, data.length,
            mEncrypted.length);
    return mSpecEncrypted;
}

/**
 * 加密数据
 * 
 * @param encryption
 * 
 *            文本
 * @return
 * 
 *         返回字符串
 * @throws Exception
 */
public static String Encryption(String encryption) throws Exception {
    byte[] entroyResult = Encrypt(encryption);
    String result = new String(Base64.encode(entroyResult, 0), "UTF-8");
    return result;
}

/**
 * 解密数据
 * 
 * @param toDecrypt
 *            文本
 * @return <br>
 *         返回字符串
 * @throws Exception
 */
public static String Decrypt(String decrypt) throws Exception {
    byte[] data = Base64.decode(decrypt, 0);
    // 秘钥
    Key secretKey = new SecretKeySpec(getKey(), KEY_ALGORITHM);
    Security.addProvider(new BouncyCastleProvider());
    Cipher cipher = Cipher.getInstance(CIPHER_ALGORITHM);
    final byte[] mData = DISPLACEMENT.getBytes();
    IvParameterSpec mIvParameterSpec = new IvParameterSpec(mData);
    cipher.init(Cipher.DECRYPT_MODE, secretKey, mIvParameterSpec);
    final byte[] mEncrypted = cipher.doFinal(data);
    // 结果
    final byte[] result = new byte[mEncrypted.length - mData.length];
    System.arraycopy(mEncrypted, mData.length, result, 0, result.length);
    return new String(result);
}
}

6、APP版本工具类

  public class VersionUtil {

/**
 * 获取应用程序名称
 * 
 * @param context
 * @return
 */
public static String getAppName(Context context) {
    try {
        PackageManager packageManager = context.getPackageManager();
        PackageInfo packageInfo = packageManager.getPackageInfo(
                context.getPackageName(), 0);
        int labelRes = packageInfo.applicationInfo.labelRes;
        return context.getResources().getString(labelRes);
    } catch (PackageManager.NameNotFoundException e) {
        e.printStackTrace();
    }
    return null;
}

/**
 * 获取版本号
 * 
 * @param context
 * @return 当前应用的版本号
 */
public static String getVersion(Context context) {
    try {
        PackageManager manager = context.getPackageManager();
        PackageInfo info = manager.getPackageInfo(context.getPackageName(),
                0);
        String version = info.versionName;
        return version;
    } catch (PackageManager.NameNotFoundException e) {
        e.printStackTrace();
        return "";
    }
}

/**
 * 版本比较
 * 
 * @param nowVersion
 *            app版本
 * @param serverVersion
 *            服务器版本
 * @return
 */
public static boolean compareVersion(String nowVersion, String serverVersion) {
    if (nowVersion != null && serverVersion != null) {
        String[] nowVersions = nowVersion.split("\\.");
        String[] serverVersions = serverVersion.split("\\.");
        if (nowVersion != null && serverVersion != null
                && nowVersions.length > 1 && serverVersions.length > 1) {
            int nowVersionFirst = Integer.parseInt(nowVersions[0]);
            int serverVersionFirst = Integer.parseInt(serverVersions[0]);
            int nowVersionSecond = Integer.parseInt(nowVersions[1]);
            int serverVersionSecond = Integer.parseInt(serverVersions[1]);
            if (nowVersionFirst < serverVersionFirst) {
                return true;
            } else if (nowVersionFirst == serverVersionFirst
                    && nowVersionSecond < serverVersionSecond) {
                return true;
            }
        }
    }
    return false;
}
}

7、GlideUtils

话说用开源库的时候应该自行封装一下,为了后面修改方便。
public class GlideUtils {

public GlideUtils(){
    throw new AssertionError();
}

/**
 * 显示照片
 * @param context
 * @param imageView
 * @param url
 */
public static void displays(Context context, ImageView imageView, Object url) {
    Glide.with(context).load(url).skipMemoryCache(true)  //跳过内存缓存
            .diskCacheStrategy(DiskCacheStrategy.ALL) //硬盘缓存全部
           .into(imageView);
}

/**
 * 显示图片
 * @param context
 * @param imageView
 * @param url
 * @param tag
 */
public static void display(Context context, ImageView imageView, String url, Object tag) {
    Glide.with(context).load(url).
            error(R.drawable.ic_error).placeholder(R.drawable.ic_progress).into(imageView);
}

public static void display(Context context, ImageView imageView, String url, int progressId) {
    RequestManager manager = Glide.with(context);
    DrawableTypeRequest<String> load = manager.load(url);
    load.error(R.drawable.ic_error).placeholder(new ColorDrawable(Color.GRAY)).into
            (imageView);
    if (progressId != -1) {
        load.placeholder(progressId);
    }
}

public static void display(Context context, ImageView imageView, String url) {
    display(context, imageView, url, -1);
}

public static void cancel(Context context) {
}
/**
 * 设置磁盘缓存大小和位置,这里设置150M
 */
public static void setInnerCacheDir(Context context){
    GlideBuilder builder = new GlideBuilder(context);
    builder.setDiskCache(new InternalCacheDiskCacheFactory(context, "ImgCache", 150 * 1024 * 1024));
}

/**
 * 可以用ExternalCacheDiskCacheFactory来把你的磁盘缓存放到sd卡的公共缓存目录上,这里默认设置150M
 */
public static void setDiskCacheDir(Context context){
    GlideBuilder builder = new GlideBuilder(context);
    builder.setDiskCache( new ExternalCacheDiskCacheFactory(context, "ImgCache", 150 * 1024 * 1024));
}

/**
 * 清除缓存
 */
public static  void clearCache(final Context context){
    Glide.get(context).clearMemory(); //清理内存缓存
    new Thread(new Runnable() {
        @Override
        public void run() {
            Glide.get(context).clearDiskCache(); //清理磁盘缓存
        }
    }).start();
}
}

8、缓存工具类

  public class CacheUtil {

public CacheUtil() {
    throw new UnsupportedOperationException("cannot be instantiated");
}

/**
 * 得到缓存大小
 *
 * @param context 上下文
 * @return
 * @throws IOException
 */
public static String getTotalCacheSize(Context context) throws IOException {
    //缓存大小
    long cacheSize = getFolderSize(context.getCacheDir());
    // 如果SD卡正常挂载才可以创建文件或者写入文件等
    if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {
        cacheSize += getFolderSize(context.getCacheDir());
    }
     return  getFormatSize(cacheSize);
}

/**
 * 得到临时缓存数据
 *
 * @param file
 * @return
 * @throws IOException
 */
public static long getFolderSize(File file) throws IOException {
    long size = 0;
    //文件
    File[] fileList = file.listFiles();
    for (int i = 0; i < fileList.length; i++) {
        if (fileList[i].isDirectory()) {
            size = size + getFolderSize(fileList[i]);
        } else {
            size = size + fileList[i].length();
        }
    }
    return size;
}

/**
 * 清除所有缓存
 */
public static void clearAllCache(Context context) {
    //删除缓存
    deleteDir(context.getCacheDir());
    //如果存在SD卡则删除本地缓存
    if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {
        deleteDir(context.getExternalCacheDir());
    }

}

/**
 * 是否删除文件
 *
 * @return
 */
public static boolean deleteDir(File dir) {
    // 文件不为空并且是一个文件夹时
    if (dir != null && dir.isDirectory()) {
        //得到文件集合
        String[] child = dir.list();
        for (int i = 0; i < child.length; i++) {
            //是否删除成功
            boolean isSuccess = deleteDir(new File(dir, child[i]));
            if (!isSuccess) {
                return false;
            }
        }
    }
    return dir.delete();
}

/**
 * 格式化
 *
 * @return
 */
public static String getFormatSize(double size) {
    //KB
    double kiloByte = size / 1024;
    if (kiloByte<1){
        return size+"Byte";
    }
    //MB
    double megaByte=kiloByte/1024;
    if (megaByte<1){
        //高精度计算结果
        BigDecimal result1=new BigDecimal(Double.toString(kiloByte));
        //四舍五入
        return result1.setScale(2,BigDecimal.ROUND_HALF_UP).toPlainString()+"KB";
    }
    //GB
    double gigaByte = megaByte/1024;
    if (gigaByte<1){
        BigDecimal result2= new BigDecimal(Double.toString(megaByte));
        return  result2.setScale(2,BigDecimal.ROUND_HALF_UP).toPlainString()+"MB";
    }
    //TB
    double teraByte =gigaByte/1024;
    if (teraByte<1){
        BigDecimal result3= new BigDecimal(Double.toString(gigaByte));
        return  result3.setScale(2,BigDecimal.ROUND_HALF_UP).toPlainString()+"GB";
    }
    BigDecimal result4= new BigDecimal(teraByte);
    return result4.setScale(2,BigDecimal.ROUND_HALF_UP).toPlainString()+"TB";
}
}

9、SharedPreferences封装类

  public class SPUtils {
/**
 * 保存在手机里面的文件名
 */
public static final String FILE_NAME = "share_data";

/**
 * 保存数据的方法,我们需要拿到保存数据的具体类型,然后根据类型调用不同的保存方法
 * 
 * @param context
 * @param key
 * @param object
 */
public static void put(Context context, String key, Object object) {

    SharedPreferences sp = context.getSharedPreferences(FILE_NAME,
            Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = sp.edit();

    if (object instanceof String) {
        editor.putString(key, (String) object);
    } else if (object instanceof Integer) {
        editor.putInt(key, (Integer) object);
    } else if (object instanceof Boolean) {
        editor.putBoolean(key, (Boolean) object);
    } else if (object instanceof Float) {
        editor.putFloat(key, (Float) object);
    } else if (object instanceof Long) {
        editor.putLong(key, (Long) object);
    } else {
        editor.putString(key, object.toString());
    }

    /**
     * commit操作使用了SharedPreferencesCompat.apply进行了替代,目的是尽可能的使用apply代替commit
     * 因为commit方法是同步的,并且我们很多时候的commit操作都是UI线程中,毕竟是IO操作,尽可能异步;
     */
    SharedPreferencesCompat.apply(editor);
}

/**
 * 得到保存数据的方法,我们根据默认值得到保存的数据的具体类型,然后调用相对于的方法获取值
 * 
 * @param context
 * @param key
 * @param defaultObject
 * @return
 */
public static Object get(Context context, String key, Object defaultObject) {
    SharedPreferences sp = context.getSharedPreferences(FILE_NAME,
            Context.MODE_PRIVATE);

    if (defaultObject instanceof String) {
        return sp.getString(key, (String) defaultObject);
    } else if (defaultObject instanceof Integer) {
        return sp.getInt(key, (Integer) defaultObject);
    } else if (defaultObject instanceof Boolean) {
        return sp.getBoolean(key, (Boolean) defaultObject);
    } else if (defaultObject instanceof Float) {
        return sp.getFloat(key, (Float) defaultObject);
    } else if (defaultObject instanceof Long) {
        return sp.getLong(key, (Long) defaultObject);
    }

    return null;
}

/**
 * 移除某个key值已经对应的值
 * 
 * @param context
 * @param key
 */
public static void remove(Context context, String key) {
    SharedPreferences sp = context.getSharedPreferences(FILE_NAME,
            Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = sp.edit();
    editor.remove(key);
    SharedPreferencesCompat.apply(editor);
}

/**
 * 清除所有数据
 * 
 * @param context
 */
public static void clear(Context context) {
    SharedPreferences sp = context.getSharedPreferences(FILE_NAME,
            Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = sp.edit();
    editor.clear();
    SharedPreferencesCompat.apply(editor);
}

/**
 * 查询某个key是否已经存在
 * 
 * @param context
 * @param key
 * @return
 */
public static boolean contains(Context context, String key) {
    SharedPreferences sp = context.getSharedPreferences(FILE_NAME,
            Context.MODE_PRIVATE);
    return sp.contains(key);
}

/**
 * 返回所有的键值对
 * 
 * @param context
 * @return
 */
public static Map<String, ?> getAll(Context context) {
    SharedPreferences sp = context.getSharedPreferences(FILE_NAME,
            Context.MODE_PRIVATE);
    return sp.getAll();
}

/**
 * 创建一个解决SharedPreferencesCompat.apply方法的一个兼容类
 * 
 * @author dj
 */
private static class SharedPreferencesCompat {
    private static final Method sApplyMethod = findApplyMethod();

    /**

     */
    @SuppressWarnings({ "unchecked", "rawtypes" })
    private static Method findApplyMethod() {
        try {
            Class clz = SharedPreferences.Editor.class;
            return clz.getMethod("apply");
        } catch (NoSuchMethodException e) {
        }

        return null;
    }

    /**
     * 如果找到则使用apply执行,否则使用commit
     * 
     * @param editor
     */
    public static void apply(SharedPreferences.Editor editor) {
        try {
            if (sApplyMethod != null) {
                sApplyMethod.invoke(editor);
