我有一个带有多个 SwitchPreferences 的 PreferencesFragment。
在极少数平板电脑上。我看到当开关设置为关闭并且用户将其更改为打开时发生的问题，然后向下滚动将 SwitchPreference 移出屏幕。当用户向上滚动时，开关已恢复为关闭状态。
例如，在下图中。如果用户将“启用背景”设置为开，则向下滚动。然后备份。“启用背景”将再次关闭。有谁知道为什么偶尔会发生这种情况。
这是该特定 SwitchPrefence 的 xml
<PreferenceCategory
android:title="General"
android:key="pref_general_settings">
<SwitchPreference
android:key="pref_enable_backdrops"
android:title="Enable Backdrops"
android:summaryOff="Backdrops are not shown in various views"
android:summaryOn="Backdrops are shown in various views"
android:defaultValue="false" />
<SwitchPreference
android:key="pref_include_trailers"
android:title="Include Trailers"
android:summaryOff="Trailers will not be included in search results, the homescreen, and actor bio screens"
android:summaryOn="Trailers will be included in search results, the homescreen, and actor bio screens"
android:defaultValue="false" />
</PreferenceCategory>
