Question

我正在使用PreferenceFragmentCompat作为我的“首选项”页面

public class SettingsFragment extends PreferenceFragmentCompat{


@Override
public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {

    setPreferencesFromResource(R.xml.pref_page, rootKey);

 } }

并且我正在使用此主题作为我的Activity，该主题设置了我的PreferenceFragmentCompat：

  <style name="SettingsTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="android:textColor">@color/text_color</item>
    <item name="android:windowBackground">@color/colorPrimaryDarkBackground</item>
    <item name="android:textColorPrimary">@color/text_color</item>
    <item name="preferenceTheme">@style/PreferenceThemeOverlay</item>

但是我的“首选项页面”看起来像这样： Preference Page

然后我添加了自定义样式：

 <style name="SettingsTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="android:textColor">@color/text_color</item>
    <item name="android:windowBackground">@color/colorPrimaryDarkBackground</item>
    <item name="android:textColorPrimary">@color/text_color</item>
    <item name="preferenceTheme">@style/PreferenceThemeCustom</item>

<style name="PreferenceThemeCustom" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="android:textColor">@color/text_color</item>
    <item name="android:windowBackground">@color/colorPrimaryDarkBackground</item>
    <item name="android:textColorPrimary">@color/text_color</item>
    <item name="android:divider">@color/text_color</item>
</style>

所有显示都很好like this 但是当我单击EditTextPreference时，出现以下错误：

       at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:921)

然后我试图定义我的自定义首选项样式：

    <style name="PreferenceThemeCustom" parent="PreferenceThemeOverlay.v14.Material">
    <item name="android:textColor">@color/text_color</item>
    <item name="android:windowBackground">@color/colorPrimaryDarkBackground</item>
    <item name="android:textColorPrimary">@color/text_color</item>
    <item name="android:divider">@color/text_color</item>
</style>

但是设置parent =“ PreferenceThemeOverlay.v14.Material”再次导致了此问题：Preference Page

Answer 1

将<android:windowBackground="...">替换为<android:background="...">，我想应该有帮助
