android - 在 DialogFragment 中显示进度对话框

Question

我想在对话框 fragment 中显示进度对话框。

但是当我使用这段代码时

ProgressDialog prog = new ProgressDialog(ctx);
prog.setTitle(getString(R.string.pleaseWait));
prog.setMessage(getString(R.string.webpage_being_loaded));       
prog.setCancelable(false);
prog.setIndeterminate(true);
prog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
prog.show();

进度对话框显示在调用 dialogFragment 的 fragment 中，而不是 DialogFragment 本身。

我做错了什么？

给你。

import android.app.Dialog;
import android.app.ProgressDialog;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;


public class ProgressDialogFragment extends DialogFragment
{
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setCancelable(false);
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState)
    {
        ProgressDialog dialog = new ProgressDialog(getActivity(), getTheme());
        dialog.setTitle(getString(R.string.pleaseWait));
        dialog.setMessage(getString(R.string.webpage_being_loaded));
        dialog.setIndeterminate(true);
        dialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
        return dialog;
    }
}
