我想制作串列視圖，允許用戶在不點擊串列項的情況下選擇選項，將通過類似于堆疊的滑動手勢選擇專案。 在此處輸入圖片描述查看
如此影像串列中給出的將像滾動一樣移動（通過滑動更改選項）以避免拿起手指
請告訴我您是否在 android 中找到任何庫或小部件或任何其他方式
uj5u.com熱心網友回復：
創建 listview 或 recyclerview 并且必須在單擊配接器中的專案時為背景專案（）創建選擇器。
這是聚焦時編輯文本的示例選擇器
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="true"
android:state_focused="true">
<shape android:shape="rectangle">
<solid android:color="@color/white" />
<corners android:radius="6dp" />
<stroke android:width="1dp" android:color="@color/primary" />
</shape>
</item>
<item android:state_enabled="true">
<shape android:shape="rectangle">
<solid android:color="@color/white" />
<corners android:radius="6dp" />
<stroke android:width="1dp" android:color="@color/gray" />
</shape>
</item>

我找到了答案
在activity_main.xml中

在 java 或 kotline 中不需要額外的更改
