因?yàn)轫?xiàng)目用到推送功能，所以需求是知道用戶是否開(kāi)啟了通知欄的權(quán)限，并且提供滑動(dòng)按鈕進(jìn)行跳轉(zhuǎn)以便用戶進(jìn)行關(guān)閉或者開(kāi)啟。

1.獲取通知欄權(quán)限是否開(kāi)啟：

/**
 * 獲取通知欄權(quán)限是否開(kāi)啟
 * 
 */

public class NotificationsUtils {
   private static final String CHECK_OP_NO_THROW = "checkOpNoThrow";
   private static final String OP_POST_NOTIFICATION = "OP_POST_NOTIFICATION";

   @SuppressLint("NewApi")
   public static boolean isNotificationEnabled(Context context) {

      AppOpsManager mAppOps = (AppOpsManager) context.getSystemService(Context.APP_OPS_SERVICE);
      ApplicationInfo appInfo = context.getApplicationInfo();
      String pkg = context.getApplicationContext().getPackageName();
      int uid = appInfo.uid;

      Class appOpsClass = null;
      /* Context.APP_OPS_MANAGER */
      try {
         appOpsClass = Class.forName(AppOpsManager.class.getName());
         Method checkOpNoThrowMethod = appOpsClass.getMethod(CHECK_OP_NO_THROW, Integer.TYPE, Integer.TYPE,
               String.class);
         Field opPostNotificationValue = appOpsClass.getDeclaredField(OP_POST_NOTIFICATION);

         int value = (Integer) opPostNotificationValue.get(Integer.class);
         return ((Integer) checkOpNoThrowMethod.invoke(mAppOps, value, uid, pkg) == AppOpsManager.MODE_ALLOWED);

      } catch (ClassNotFoundException e) {
         e.printStackTrace();
      } catch (NoSuchMethodException e) {
         e.printStackTrace();
      } catch (NoSuchFieldException e) {
         e.printStackTrace();
      } catch (InvocationTargetException e) {
         e.printStackTrace();
      } catch (IllegalAccessException e) {
         e.printStackTrace();
      }
      return false;
   }
}

2.進(jìn)入系統(tǒng)設(shè)置界面

第一種方法

protected void requestPermission(int requestCode) {
   // TODO Auto-generated method stub
   // 6.0以上系統(tǒng)才可以判斷權(quán)限
   // 進(jìn)入設(shè)置系統(tǒng)應(yīng)用權(quán)限界面
      Intent intent = new Intent(Settings.ACTION_SETTINGS);
      startActivity(intent)；
}

第二種方法

以下代碼可以跳轉(zhuǎn)到應(yīng)用詳情，可以通過(guò)應(yīng)用詳情跳轉(zhuǎn)到權(quán)限界面(6.0系統(tǒng)測(cè)試可用)

private void getAppDetailSettingIntent(Context context) {
        Intent localIntent = new Intent();
        localIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        if (Build.VERSION.SDK_INT >= 9) {
            localIntent.setAction("android.settings.APPLICATION_DETAILS_SETTINGS");
            localIntent.setData(Uri.fromParts("package", getPackageName(), null));
        } else if (Build.VERSION.SDK_INT <= 8) {
            localIntent.setAction(Intent.ACTION_VIEW);
            localIntent.setClassName("com.android.settings","com.android.settings.InstalledAppDetails");
            localIntent.putExtra("com.android.settings.ApplicationPkgName", getPackageName());
        }
        startActivity(localIntent);
    }

這個(gè)功能不是特別重要，但是有時(shí)候確實(shí)有這樣的需求。
