我在Android应用程序中工作,并使用DialogFragment显示对话框,我想使DialogFragment不可取消.我已将对话框cancelable属性设置为false,但仍然没有影响.

请查看我的代码并建议我一个解决方案.

public class DialogTest extends DialogFragment {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        return super.onCreateDialog(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.dialog_test, container, true);
        getDialog().requestWindowFeature(STYLE_NO_TITLE);
        getDialog().setCancelable(false);

        return view;
    }
 }

我有一个可以创建并弹出DialogFragment的Fragment,但是当我点击后退按钮时,即使我显式调用setCancelable(false),它也会取消对话框; 我的DialogFragment有没有办法对后退按钮不敏感？

public class LoadingDialogFragment extends DialogFragment
{
    String title;
    String msg;

    public LoadingDialogFragment()
    {
        this.title = "Loading...";
        this.msg = "Please wait...";
    }
    public LoadingDialogFragment(String title, String msg)
    {
        this.title = title;
        this.msg = msg;
    }

    @Override
    public Dialog onCreateDialog(final Bundle savedInstanceState)
    {
        final ProgressDialog dialog = new ProgressDialog(getActivity());

        dialog.setTitle(title);
        dialog.setMessage(msg);
        dialog.setIndeterminate(true);
        dialog.setCanceledOnTouchOutside(false);
        dialog.setCancelable(false);

        return dialog;
    }

}

我从AsyncTask创建DialogFragment:

private class GpsTask extends AsyncTask<String, Integer, Integer>
{
    //ProgressDialog dialog;
    @Override
    protected void onPreExecute()
    {
        FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
        DialogFragment newFragment …
