我想为单选按钮使用VectorDrawable，但在API级别17的设备中遇到了“无效的可绘制标签vector”错误。
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/ic_list_on" android:state_checked="true" />
<item android:drawable="@drawable/ic_list_off" android:state_checked="false" />
</selector>
我正在一个片段中使用这个，而且在包含该片段的活动中将setCompatVectorFromResourcesEnabled设置为true。
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
AppCompatDelegate.setCompatVectorFromResourcesEnabled(true)
此外，我设置了
vectorDrawables.useSupportLibrary = true
在 build.gradle 中，
这是视图 xml，
<RadioGroup
android:id="@+id/list_view_type"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_gravity="end"
android:gravity="center_vertical|end"
android:padding="15dp"
android:orientation="horizontal">
<android.support.v7.widget.AppCompatRadioButton
android:id="@+id/list_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="15dp"
android:layout_marginRight="15dp"
android:background="@drawable/grid_btn_toggle"
android:button="@android:color/transparent"
android:gravity="center"
android:maxLines="1"
android:text="" />
<android.support.v7.widget.AppCompatRadioButton
android:id="@+id/grid_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/list_btn_toggle"
android:button="@android:color/transparent"
android:checked="true"
android:gravity="center"
android:maxLines="1"
android:text="" />
</RadioGroup>
这是关于矢量图像的内容之一。

在API级别为16或17的选择器中，我是否可以使用Android中的VectorDrawable作为drawable？
