startResolutionForResult-> onActivityResult resultCode始终为0

Question

我阅读了文档，并且看到了很多有关此问题的问答，但是我找不到任何东西。我将startResolutionForResult用于“位置”设置，就像在文档中写的一样。 代码看起来很简单，我的清单文件中只有一个活动MainActivity，没有片段，ACCESS_FINE_LOCATION权限。它工作正常，但onActivityResult的resultCode始终返回0。 谢谢您的帮助。

   createAndCheckLocationRequest();

}

private void createAndCheckLocationRequest() {
    mLocationRequest = new LocationRequest();
    mLocationRequest.setInterval(10000);
    mLocationRequest.setFastestInterval(5000);
    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder().addLocationRequest(mLocationRequest);
    SettingsClient client = LocationServices.getSettingsClient(this);
    Task<LocationSettingsResponse> task = client.checkLocationSettings(builder.build());
    task.addOnSuccessListener(this, new OnSuccessListener<LocationSettingsResponse>() {
        @Override
        public void onSuccess(LocationSettingsResponse locationSettingsResponse) {
            // requestLocationUpdate();
        }
    });

    task.addOnFailureListener(this, new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            if (e instanceof ResolvableApiException) {
                // Location settings are not satisfied, but this can be fixed
                // by showing the user a dialog.
                try {
                    // Show the dialog by calling startResolutionForResult(),
                    // and check the result in onActivityResult().
                    ResolvableApiException resolvable = (ResolvableApiException) e;
                    resolvable.startResolutionForResult(MainActivity.this,
                            REQUEST_CHECK_SETTINGS);
                } catch (IntentSender.SendIntentException sendEx) {
                    // Ignore the error.
                }
            }
        }
    });
}

@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if(requestCode == REQUEST_CHECK_SETTINGS){
        if(resultCode == Activity.RESULT_OK){
            // requestLocationUpdate();
            Toast.makeText(this,"*** OK ****",Toast.LENGTH_SHORT).show();
        }else{
            Toast.makeText(this,"Location request not satisfied",Toast.LENGTH_SHORT).show();
        }
    }
}
