我的代码发生了一些奇怪的事情，我不知道为什么会发生。在我的 xml 文件中，我放置了一个复选框和图像视图，但是在我的班级中发生了错误，复选框和图像视图被反转了我投射的图像视图来自复选框的 id，复选框来自图像视图的 id，当我投射我的 xml 中 imageview 的 id 上的 imageview 与它出错的复选框相同。 这是我的xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5dp" >
<CheckBox
android:id="@+id/cbo_CheckImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5px" />
<ImageView
android:id="@+id/img_thumbImage"
android:layout_width="90dp"
android:layout_height="90dp"
android:layout_marginRight="10px" />
</LinearLayout>
这是我的课
