Android如何判断通知栏权限是否开启：

     起先我是想通过app手动检测权限是否开启，进行动态设置及：

     

1. //检测权限是否开启

2. ContextCompat.checkSelfPermission()

3. //设置权限

4. ActivityCompat.requestPermissions();

但是我查阅的好些资料，都没有查到其权限名是什么，貌似没有。无奈只有放弃这种方式

检测通知栏权限是否开启

1. @RequiresApi(api = Build.VERSION_CODES.KITKAT)

2. private boolean isNotificationEnabled(Context context) {

3.  

4. String CHECK_OP_NO_THROW = "checkOpNoThrow";

5. String OP_POST_NOTIFICATION = "OP_POST_NOTIFICATION";

6.  

7. AppOpsManager mAppOps = (AppOpsManager) context.getSystemService(Context.APP_OPS_SERVICE);

8. ApplicationInfo appInfo = context.getApplicationInfo();

9. String pkg = context.getApplicationContext().getPackageName();

10. int uid = appInfo.uid;

11.  

12. Class appOpsClass = null;

13. /* Context.APP_OPS_MANAGER */

14. try {

15. appOpsClass = Class.forName(AppOpsManager.class.getName());

16. Method checkOpNoThrowMethod = appOpsClass.getMethod(CHECK_OP_NO_THROW, Integer.TYPE, Integer.TYPE,

17. String.class);

18. Field opPostNotificationValue = appOpsClass.getDeclaredField(OP_POST_NOTIFICATION);

19.  

20. int value = (Integer) opPostNotificationValue.get(Integer.class);

21. return ((Integer) checkOpNoThrowMethod.invoke(mAppOps, value, uid, pkg) == AppOpsManager.MODE_ALLOWED);

22.  

23. } catch (Exception e) {

24. e.printStackTrace();

25. }

26. return false;

27. }

当通知栏权限未开启时跳转到自身的设置界面

1. private void toSetting() {

2. Intent localIntent = new Intent();

3. localIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

4. if (Build.VERSION.SDK_INT >= 9) {

5. localIntent.setAction("android.settings.APPLICATION_DETAILS_SETTINGS");

6. localIntent.setData(Uri.fromParts("package", getPackageName(), null));

7. } else if (Build.VERSION.SDK_INT <= 8) {

8. localIntent.setAction(Intent.ACTION_VIEW);

9. localIntent.setClassName("com.android.settings", "com.android.setting.InstalledAppDetails");

10. localIntent.putExtra("com.android.settings.ApplicationPkgName", getPackageName());

11. }

12. startActivity(localIntent);

13. }
