应用程序在插入引导程序下拉菜单时停止。已使用代码部分中提供的位。按钮、标签等正在工作，但插入后下拉应用程序停止

这是xml中使用的代码
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:components="http://schemas.android.com/apk/res-auto"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<com.beardedhen.androidbootstrap.BootstrapDropDown
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:bootstrapBrand="regular"
app:roundedCorners="true"
app:dropdownResource="@array/bootstrap_dropdown_example_data"
>
</com.beardedhen.androidbootstrap.BootstrapDropDown>

嘿，我想我也遇到过类似的问题。我所做的是将一个字符串数组添加到project/app/res/values/ String s.xml中。
将字符串数组添加到strings.xml中，如下所示：
<resources>
...
<string-array name="bootstap_dropdown_example_data">
<item>item1</item>
<item>item2</item>
<item>item3</item>
</string-array>
</resources>确保"string-array name“与位于app:dropdownResource="@ array /...”的XML文件中的数组名称相匹配。确保您的strings.xml数组中有项。
如果这对你有用，请让我知道！
