Android請求權限請求只有第一個

我在Android應用程序中工作，並且我在Activity中聲明瞭方法requestAppPermissions。Android請求權限請求只有第一個

那麼，這個代碼發生了什麼，由於某種原因，它要求第一個（在這種情況下，位置）並跳過其他的;但是，我還可以將一些其他權限第一if的方法是請求的第一個，跳過等。

我有什麼錯我的代碼？

public void requestAppPermissions(){ 
    if (Build.VERSION.SDK_INT >= 21) { 
     if (ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) { 
      if (ActivityCompat.shouldShowRequestPermissionRationale(this, android.Manifest.permission.ACCESS_FINE_LOCATION)) { 
       //El usuario denegó los permisos con el botón "Don't show again!!!" 
       startActivity(new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS, Uri.parse("package:" + BuildConfig.APPLICATION_ID))); 
      } else { 
       //Se solicita el permiso al usuario 
       ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION}, 1); 
      } 
     }else{ 
      LocationManager lm = (LocationManager) this.getApplicationContext().getSystemService(Context.LOCATION_SERVICE); 
      Location location = lm.getLastKnownLocation(LocationManager.NETWORK_PROVIDER); 

      if(location != null){ 
       Double latitude = location.getLatitude(); 
       Double longitude = location.getLongitude(); 
       //new MapFunctions().RecenterMap(googleMap, new LatLng(latitude, longitude), 14, ""); 
       LOCATION_CENTER = new LatLng(latitude, longitude); 
       // Toast.makeText(MainActivity.this, "latitude: " + latitude + " - longitude" + longitude, Toast.LENGTH_LONG).show(); 
      } 
     }

      } else { 
       ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.CAMERA}, 2); 
      } 
     }

你需要togheter它們堆疊在一個單一的請求。您應該檢查每個權限的狀態，如果未提供權限，則將其存儲在字符串數組中，然後最後可以發送包含您需要的所有權限的數組的單個請求。請閱讀此處：https://stackoverflow.com/a/34343101/2910520 – MatPag

類似的東西來，這可能是有益的......

String[] neededPermissions = new String[]{ 
    android.Manifest.permission.ACCESS_FINE_LOCATION, 
    android.Manifest.permission.CAMERA, 
    android.Manifest.permission.WRITE_EXTERNAL_STORAGE //if you can write, you can read 
} 

public static List<String> getPermissionsRequest(@NonNull Context context, 
               @NonNull String[] permissions){ 
    List<String> permissionsToRequest = new ArrayList<>(); 
    for (int i = 0; i < permissions.length; i++){ 
     if (ContextCompat.checkSelfPermission(context, permissions[i]) 
        != PackageManager.PERMISSION_GRANTED){ 
      permissionsToRequest.add(permissions[i]); 
     } 
    } 
    return permissionsToRequest; 
} 

//now in the onCreate of your Activity you can do something like this: 
List<String> permissionsToRequest = getPermissionsRequest(this, neededPermissions); 
//if permissionsToRequest size is > 0 you need some more permission(s) 
if (permissionsToRequest.size() > 0){ 
    ActivityCompat.requestPermissions(MainActivity.this, 
     permissionsToRequest.toArray(new String[0]), PERMISSION_ALL_REQUEST_CODE); 
} 

//now in the onRequestPermissionsResult you can handle everything 
//as always and proceeed if everything is ok

我沒有測試，目前這一點，但應該工作
