我正在尝试将multiSelectListPreference添加到我的xml设置中,但我不断收到以下错误消息
android.view.InflateException: Binary XML file line #12: Error inflating class (not found)android.support.v7.preference.MultiSelectListPreference
Caused by: java.lang.ClassNotFoundException: Didn't find class "android.support.v7.preference.MultiSelectListPreference" on path: DexPathList
我正在使用支持我的xml文件:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.preference.PreferenceScreen xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android">
<android.support.v7.preference.MultiSelectListPreference app:title="Hello title"
app:key="test" app:summary="Select vo"
app:entries="@array/planets_array" app:entryValues="@array/planets_arrayvalues"
android:defaultValue="@array/planets_arrayvalues"
/>
</android.support.v7.preference.PreferenceScreen>
strings.xml
<string-array name="planets_array">
<item>Mercury</item>
<item>Venus</item>
</string-array>
<string-array name="planets_arrayvalues">
<item>0</item>
<item>1</item>
</string-array>
如果我使用android.support.v7.preference.ListPreference代替它正常工作
我的构建gradle文件
