Android请求权限请求只有第一个

我在Android应用程序中工作，并且我在Activity中声明了方法requestAppPermissions。Android请求权限请求只有第一个

那么，这个代码发生了什么，由于某种原因，它要求第一个（在这种情况下，位置）并跳过其他的;但是，我还可以将一些其他权限第一if的方法是请求的第一个，跳过等。

我有什么错我的代码？

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(); 
      } 
     } 

     if (ContextCompat.checkSelfPermission(this, android.Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) { 
      if (ActivityCompat.shouldShowRequestPermissionRationale(this, android.Manifest.permission.CAMERA)) { 
       startActivity(new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS, Uri.parse("package:" + BuildConfig.APPLICATION_ID))); 
      } else { 
       ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.CAMERA}, 2); 
      } 
     } 

     if (ContextCompat.checkSelfPermission(this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) { 
      if (ActivityCompat.shouldShowRequestPermissionRationale(this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE)) {

      } else { 
       ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE}, 3); 
      } 
     }

      if (ActivityCompat.shouldShowRequestPermissionRationale(this, android.Manifest.permission.READ_EXTERNAL_STORAGE)) {

      } else { 
       ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.READ_EXTERNAL_STORAGE}, 4); 
      } 
     } 

    } 
}

你需要togheter它们堆叠在一个单一的请求。您应该检查每个权限的状态，如果未提供权限，则将其存储在字符串数组中，然后最后可以发送包含您需要的所有权限的数组的单个请求。请阅读此处：https://stackoverflow.com/a/34343101/2910520 – MatPag

类似的东西来，这可能是有益的......

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

我没有测试，目前这一点，但应该工作
