android 通知栏授权,Android通知栏权限是否开启

通知栏权限是否开启

需要分系统版本来操作

4.4版本一下不处理，4.4到8.0,8.0以上

@RequiresApi(api = Build.VERSION_CODES.KITKAT)

public static boolean isNotificationEnabled(Context context) {

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

//8.0手机以上

if (((NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE)).getImportance() == NotificationManager.IMPORTANCE_NONE) {

return false;

}

}

String CHECK_OP_NO_THROW = "checkOpNoThrow";

String OP_POST_NOTIFICATION = "OP_POST_NOTIFICATION";

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;

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 (Exception e) {

e.printStackTrace();

}

return false;

}

跳转到手机设置界面：

fun toSetting(activity: Activity, requestCode: Int) {

val intent = Intent()

intent.action = "android.settings.APPLICATION_DETAILS_SETTINGS"

intent.data = Uri.fromParts("package", activity.packageName, null)

activity.startActivityForResult(intent, requestCode)

}

设置界面返回处理：

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {

super.onActivityResult(requestCode, resultCode, data)

if (requestCode == 101) {

if (PermissionsUtil.isNotificationEnabled(mActivity!!) ) {

ViewUtils.visibility(card_view_notification_status,false)

}

}

}

如果解决问题，是不是要打赏一波呢
