带有AppCompat主题的Android DialogFragment [英] Android DialogFragment with AppCompat theme issue

问题描述

我试图用AppCompat主题创建DialoFragment，但是当我使用AppCompat主题时，对话框标题未显示.

I've trying to create DialoFragment with AppCompat theme, but when i use AppCompat theme, dialog title is not shown.

我正在使用定义的样式:

I'am using defined style:

<style name="DialogFragment" parent="Theme.AppCompat.Light.Dialog"/>

将父主题更改为:

<style name="DialogFragment" parent="android:Theme.Material.Light.Dialog"/>

或

<style name="DialogFragment" parent="android:Theme.Holo.Light.Dialog"/>

标题显示正确.

我的对话框代码:

public class InfoDialog extends DialogFragment {

    public static final String TAG = InfoDialog.class.getName();

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        Dialog dialog = super.onCreateDialog(savedInstanceState);
        dialog.getWindow().setTitle(getString(R.string.dialog_title));

        return dialog;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setStyle(DialogFragment.STYLE_NORMAL, R.style.DialogFragment);
    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        return inflater.inflate(R.layout.info_dialog, container, false);
    }
}

任何想法是导致问题的原因吗? 应用程序使用com.android.support:appcompat-v7:22.2.0，也许这是平台错误?

Any ideas what is causing the issue? Application use com.android.support:appcompat-v7:22.2.0, maybe this is platform bug?

推荐答案

尝试扩展 AppCompatDialogFragment 而不是DialogFragment.那应该可以解决问题.

Try extending AppCompatDialogFragment instead of DialogFragment. That should do the trick.
