我有一张可以改变的照片。 我可以在我的画廊中选择一张照片或拍摄照片。 当我拍摄照片时，我裁剪图像。 但该应用程序需要时间来裁剪我的照片，所以我想显示progressDialog。
我的progressDialog出现在我的应用程序中，但它被我裁剪照片的屏幕隐藏了。
如何在我裁剪照片的屏幕内显示progressDialog？
抱歉我的英语不好......
我的代码：
public class FragmentMonCompte extends Fragment {
private ImageView ivAvatar;
// YOU CAN EDIT THIS TO WHATEVER YOU WANT
private static final int CAPTURE_PICTURE = 0;
private static final int SELECT_PICTURE = 1;
private String selectedImagePath;
// ADDED
private String filemanagerstring;
private Uri mCapturedImageURI;
ProgressDialog mProgressDialog = null;
boolean isPDShow;
Navigation navigation;
Intent data;
Bitmap photo;
Bundle extras;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_compte, container,
false);
ivAvatar = (ImageView) rootView.findViewById(R.id.iv_avatar);
ivAvatar.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
final Navigation navigation = (Navigation) getActivity();
mProgressDialog = new ProgressDialog(navigation);
mProgressDialog.setMessage("Opération en cours...");
mProgressDialog.setTitle("Patientez");

"Choisir une image", "Annuler"};
