我正在尝试为 checkboxPreferences 编写自定义视图。我有：
<CheckBoxPreference
android:key="@string/pref_acceptableads"
android:summaryOff="@string/pref_acceptableads_summary_off"
android:summaryOn="@string/pref_acceptableads_summary_on"
android:title="@string/pref_acceptableads_title"
android:widgetLayout="@layout/helpfulcheckbox_layout" />
和：
<?xml version="1.0" encoding="UTF-8"?>
<ViewGroup xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+android:id/widget_frame"
android:layout_width="wrap_content"
android:layout_height="match_parent">
<ImageView
android:id="@+id/image"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="@drawable/image" />
<CheckBox
android:id="@+id/checkbox"
android:layout_width="0dp"
android:layout_height="wrap_content" />
</ViewGroup>
问题出在我的视图组上。我收到一个例外：
