我怎样才能打开一个ProgressDialog上DialogFragment的顶部？ [英] How can I open a ProgressDialog on top of a DialogFragment?

问题描述

我有这样的机器人活动/一个按钮的布局。当我点击这个按钮，它会打开2纺纱一个DialogFragment。当DialogFragment显示出来，我需要填充这两个纺纱由Web服务返回的项目。因此，在等待的服务来回报，我想在我刚刚开了DialogFragment显示ProgressDialog。

I have this Android activity/layout with a button. When I click this button, it opens a DialogFragment with 2 spinners. When the DialogFragment shows up, I need to populate these 2 spinners with items returned by a web service. So, while waiting for the service to return, I'd like to display a ProgressDialog over the DialogFragment I've just opened.

现在的问题是，我似乎无法使ProgressDialog在DialogFragment的顶部。我可以看到ProgressDialog所显示的DialogFragment的背后，是有可能使ProgressDialog显示了一切？

The problem is I can't seem to make the ProgressDialog on top of the DialogFragment. I can see the ProgressDialog being shown behind the DialogFragment, is it possible to make the ProgressDialog being displayed over everything else?

我的code是这样的：

My code is like this:

public class RegionalFragment extends DialogFragment {

    private View view;
    private Activity activity;
    private Spinner spinner1;
    private Spinner spinner2;
    private ProgressDialog progressDialog;

    public RegionalFragment(Activity activity) {
        this.activity = activity;
        LayoutInflater inflater = activity.getLayoutInflater();
        view = inflater.inflate(R.layout.spinner_selection, null);
        this.progressDialog = new ProgressDialog(activity);
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        AlertDialog.Builder builder =
            new AlertDialog.Builder(activity)
                    .setTitle(R.string.title)
                    .setView(view)
                    .setPositiveButton(R.string.ok, new MyListener(activity))
                    .setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int id) {
                            getDialog().cancel();
                        }
                    });

        progressDialog.getWindow().setBackgroundDrawable(new ColorDrawable(1));
        progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
        progressDialog.setCancelable(false);
        progressDialog.setIndeterminate(true);
        progressDialog.setMessage("Please wait...");
        progressDialog.show();

        invokeAsyncWebService();

    return builder.create();
}

谢谢！

推荐答案

显然那是一个普遍抱怨的主题与 ProgressDialog ，我建议你尝试一个正常的对话，与创建建筑商和其布局（一个自定义您制作），包括进度条或加载或任何你需要的。这应该解决您的问题。

Apparently thats a widely complained about subject with ProgressDialog, I suggest you try a normal dialog, created with the builder and whose layout (a custom one made by you) includes the progress bar or loading or whatever you need. This should solve your problem.
