我正在尝试实现 Marshmallow 的权限支持，但我在“onRequestPermissionsResult”中的代码从未被调用。

在 Activity 中工作时，它的工作正常但在片段中我遇到了问题，即控件没有进入 onRequestPermissionsResult()

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                            mCheckPermission();
                        }

在 mCheckPermission() 中：-

public void mCheckPermission() {
        if (ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION)
                != PackageManager.PERMISSION_GRANTED || ContextCompat.checkSelfPermission(getActivity(),
                Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            requestPermissions(new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION},
                    PERMISSION_REQUEST_COARSE_LOCATION );

        }
    }

对话框弹出 2 个按钮。拒绝和允许。单击按钮时，控件未进入 onRequestPermissionCheck()；

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

        switch (requestCode){
            case PERMISSION_REQUEST_COARSE_LOCATION: {
                if (grantResults.length > 0
                        && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                    Toast.makeText(getActivity(), "permission granted", Toast.LENGTH_LONG).show();
                    //call your action

                } …
