Question

在我的Android项目中，我使用类方法为所有视图设置字体类型，方法如下：

    public  void overrideFonts(final Context context, final View v ) {
    try {
        if (v instanceof ViewGroup) {
            ViewGroup vg = (ViewGroup) v;
            for (int i = 0; i < vg.getChildCount(); i++) {
                View child = vg.getChildAt(i);
                overrideFonts(context, child);
            }
        } else if (v instanceof TextView) {
            ((TextView) v).setTypeface(Typeface.createFromAsset(context.getAssets(),"font/aFont.ttf"));
        }
    } catch (Exception e) {

    }
}

除非我改变设备的方向，否则我的片段工作正常。之后，这种方法甚至无法恢复到肖像的方向！我试过saveInstanceState（我觉得这不是我的问题）.... 那么问题是什么？！

这是我在其中使用此方法的片段类。

public class aboutUs extends Fragment {

MUF option;
RelativeLayout relativeLayout;


@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    option = new MUF(getActivity(), getContext());
    relativeLayout = (RelativeLayout) getActivity().findViewById(R.id.aboutus_fragment);
    option.overrideFonts(getContext(), relativeLayout);
    Toast.makeText(getActivity(), "onActivityCreated", Toast.LENGTH_SHORT).show();


}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View view = inflater.inflate(R.layout.fragment_about_us, container, false);
    return view;


}


}

从您的AndroidManifest.xml中删除<activity android:name=".ui.activities.MainActivity"//Your fragment's activity android:configChanges="orientation|keyboardHidden|screenSize" android:screenOrientation="portrait" />和"orientation"，如果已添加到您的片段的活动中，也可以从"screenSize"和android:configChanges删除
