Android x PreferenceFragmentCompat 重叠 androidx.fragment.app.Fragment

Question

我有设置片段，它作为逻辑工作得很好，但每当我切换到 PreferenceFragmentCompat 它的布局背景变得透明，最后一个片段和设置片段布局相互重叠。

我有导航抽屉，我在其中设置了片段，它只发生在 PreferenceFragmentCompat 导航抽屉中的其他片段工作正常。

我试着在 PreferenceFragmentCompat XML 中设置背景颜色 android:background="?android:attr/colorBackground" 但它仍然重叠

在您的设置片段中，添加：

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = super.onCreateView(inflater, container, savedInstanceState);
    view.setBackgroundColor(getResources().getColor(android.R.color.white));
    return view;
}
