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>

</RelativeLayout>

嘿，我相信我有类似的问题。我所做的是将一个字符串数组添加到 project/app/res/values/strings.xml 中。

像这样将字符串数组添加到您的 strings.xml 中：

<resources>
...
<string-array name="bootstap_dropdown_example_data">
    <item>item1</item>
    <item>item2</item>
    <item>item3</item>
</string-array>
</resources>

确保“字符串数组名称”与您的 XML 文件中的数组名称匹配 app:dropdownResource="@array/..." 确保您的 strings.xml 数组中有项目。

让我知道这是否适合您！
