当我在Manifest中拥有位置权限并且为什么出现此警报对话框错误时，是否需要用于访问位置的警报对话框？

我正在构建一个应用程序，我正在使用位置。我已经宣布在明显的权限：当我在Manifest中拥有位置权限并且为什么出现此警报对话框错误时，是否需要用于访问位置的警报对话框？

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

我现在就需要作出警告对话框，使用户能够准许他的位置的设备上，或者我已经做到了与清单此权限吗？当我为开启GPS上我得到这个错误对话框：

这是我的警告对话框：

private void showDialogForAllowingLocation() { 
     AlertDialog.Builder builder = new AlertDialog.Builder(this); 
     builder.setCancelable(false); 
     builder.setTitle(getResources().getString(R.string.enable_permission)); 
     builder.setMessage(getResources().getString(R.string.enable_access)); 
     builder.setInverseBackgroundForced(true); 
     builder.setPositiveButton(getResources().getString(R.string.enable), new DialogInterface.OnClickListener() { 
      public void onClick(DialogInterface dialog, int which) { 
       startActivity(
         new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS)); 
      } 
     }); 
     builder.setNegativeButton(getResources().getString(R.string.ignore), new DialogInterface.OnClickListener() { 
      public void onClick(DialogInterface dialog, int which) { 
       dialog.dismiss(); 
      } 
     }); 
     AlertDialog alert = builder.create(); 
     alert.show(); 
    } 
    private void EnableGPSIfPossible() { 
     final LocationManager manager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); 
     if (!manager.isProviderEnabled(LocationManager.GPS_PROVIDER)) { 
      showDialogForAllowingLocation(); 
     } 
    }

哪里是我的错？

您必须添加对话框，提示用户对GPS如果手机GPS关闭。 –

请参阅编辑的问题。 – Atenica

是的，如果targetSdkVersion i等于或大于23，并且手机使用Android M或更高版本 - 请点击此处查看 - https://inthecheesefactory.com/blog/things-you-need-to-know-about -android-m-permission-developer-edition/en - 否则，当您在Android M下面下载低于23的应用程序时，它会要求您在安装应用程序之前授予许可权 – Tasos

是的。这确保您的应用程序不会中断运行。在应用程序启动之前检查互联网连接和gps。

您需要检查用户是否打开了GPS，如果没有，那么您必须显示提示对话框。

但是，请注意，从Android 6.0（API 23）开始，您必须手动要求用户授予权限，因为ACCESS_FINE_LOCATION被归类为危险。在权限组此处了解详情：https://developer.android.com/guide/topics/security/permissions.html

Yes you need to runtime permission for Android 6.0 or greater follow that

private static final int REQUEST_RUNTIME_PERMISSION = 123; 


    if (CheckPermission(demo.this, Manifest.permission.ACCESS_FINE_LOCATION)) { 


     showDialogForAllowingLocation(); 

    } else { 
     // you do not have permission go request runtime permissions 
     RequestPermission(demo.this, Manifest.permission.ACCESS_FINE_LOCATION, REQUEST_RUNTIME_PERMISSION); 
    } 



public void RequestPermission(Activity thisActivity, String Permission, int Code) { 
     if (ContextCompat.checkSelfPermission(thisActivity, 
       Permission) 
       != PackageManager.PERMISSION_GRANTED) { 
      if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity, 
        Permission)) { 
       showDialogForAllowingLocation(); 

      } else { 
       ActivityCompat.requestPermissions(thisActivity, 
         new String[]{Permission}, 
         Code); 
      } 
     } 
    } 

    public boolean CheckPermission(Activity context, String Permission) { 
     if (ContextCompat.checkSelfPermission(context, 
       Permission) == PackageManager.PERMISSION_GRANTED) { 
      return true; 
     } else { 
      return false; 
     } 
    }

使用许可专为android version > L

if (ActivityCompat.checkSelfPermission 
       (this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED 
       && 
       ActivityCompat.checkSelfPermission 
         (this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) 
     { 
      requestPermissions(new String[]{ 
        Manifest.permission.ACCESS_COARSE_LOCATION, 
        Manifest.permission.ACCESS_FINE_LOCATION 
      }, 1); 

     }

权限处理：

@Override 
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { 
switch (requestCode) { 

    case 1: 
     if (grantResults[0] != PackageManager.PERMISSION_GRANTED){ 
      //do something 
     } 
    default: 
     super.onRequestPermissionsResult(requestCode, permissions, grantResults); 
} 
}
