onrequestpermissionsresult補助結果總是-1

onrequestpermissionsresult方法grantResults [0]總是返回-1 情況下都允許和拒絕請檢查下面我的代碼： -onrequestpermissionsresult補助結果總是-1

請求的位置的權限： -

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) { 
       int hasReadStatePermission = getActivity().checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION); 
       if (hasReadStatePermission != PackageManager.PERMISSION_GRANTED) { 
        requestPermissions(new String[]{Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.ACCESS_COARSE_LOCATION}, Constants.RequestCode.KEY_PERMISSION_ACCESS_FINE_LOCATION); 
       }else { 
        setLocation(); 
       } 
      }else { 
       DialogUtils.dialogTwoButton(getActivity(), "Allow", "Deny", getString(R.string.msg_get_gps_access), new Runnable() { 
        @Override 
        public void run() { 
         setLocation(); 
        } 
       }, new Runnable() { 
        @Override 
        public void run() { 
         Intent intent=new Intent(getActivity(), ChangeLocationManualyActivity.class); 
         startActivityForResult(intent,Constants.RequestCode.LOCATION_CHANGE); 
        } 
       });

權限回調方法，其中PackageManager.PERMISSION_GRANTED = 0，PackageManager.PERMISSION_DENIED = -1

@Override 
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { 
     if(requestCode==Constants.RequestCode.KEY_PERMISSION_ACCESS_FINE_LOCATION) 
      if(grantResults.length>0&& grantResults[0] == PackageManager.PERMISSION_GRANTED) { 
       setLocation(); 
      }else{ 
       new Handler().postDelayed(new Runnable() { 
        @Override 
        public void run() { 
         Intent intent=new Intent(getActivity(), ChangeLocationManualyActivity.class); 
         startActivityForResult(intent,Constants.RequestCode.LOCATION_CHANGE); 
        } 
       },3000); 
      } 
    }

是應用程序請求權限？ –

是應用程序請求權限 –

對於遲來的評論感到抱歉發生此問題是因爲我設置了清單權限僅針對並且在運行時請求Manifest.permission .ACCESS_FINE_LOCATION，Manifest.permission.ACCESS_COARSE_LOCATION。 –

請下面的代碼檢查： -

public static boolean selfPermissionGranted(Context context, String permission) { 
     // For Android < Android M, self permissions are always granted. 
     boolean result = true; 
     int targetSdkVersion; 
     try { 
      final PackageInfo info = context.getPackageManager().getPackageInfo(
        context.getPackageName(), 0); 
      targetSdkVersion = info.applicationInfo.targetSdkVersion; 
     } catch (PackageManager.NameNotFoundException e) { 
      targetSdkVersion = 21; 
      e.printStackTrace(); 
     } 
     if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { 

      if (targetSdkVersion >= Build.VERSION_CODES.M) { 
       // targetSdkVersion >= Android M, we can 
       // use Context#checkSelfPermission 
       result = context.checkSelfPermission(permission) 
         == PackageManager.PERMISSION_GRANTED; 
      } else { 
       // targetSdkVersion < Android M, we have to use PermissionChecker 
       result = PermissionChecker.checkSelfPermission(context, permission) 
         == PermissionChecker.PERMISSION_GRANTED; 
      } 
     } 

     System.out.println("Result is==>" + result); 
     return result; 
    }

給呼叫象下面這樣： -

if (!selfPermissionGranted(this, Manifest.permission.ACCESS_FINE_LOCATION)) { 
       ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.READ_PHONE_STATE, Manifest.permission.WRITE_EXTERNAL_STORAGE}, 
         PERMISSION_ACCESS_COARSE_LOCATION); 
}

及其me.Hope工作它可以幫助你。

檢查grantResults[1]而不是grantResults[0]。
