在BaseActivity重写onRequestPermissionsResult方法，用户允许或者拒绝权限后，回调该方法：

@Overridepublic void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {    MPermissionUtils.onRequestPermissionsResult(requestCode, permissions, grantResults);    super.onRequestPermissionsResult(requestCode, permissions, grantResults);}

在合适的地方调用：

MyEditHeardPopupWindow popupWindow = new MyEditHeardPopupWindow(getMyActivity());popupWindow.showAtLocation(getMyActivity().findViewById(R.id.llHome5), Gravity.BOTTOM, 0, 0);popupWindow.setMyEditHeardListener(new MyEditHeardListener() {    @Override    public void button1() {        MPermissionUtils.requestPermissionsResult(getMyActivity(), 1, new String[]{android.Manifest.permission.CAMERA}, new MPermissionUtils.OnPermissionListener() {            @Override            public void onPermissionGranted() {                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);                startActivityForResult(intent, SELECT_CAMERA);            }            @Override            public void onPermissionDenied() {                MPermissionUtils.showTipsDialog(getMyActivity());            }        });    }
