如何在旋转动画后在 ImageView 上设置 OnClickListener

Question

我想在使用 addView 方法动态创建 ImageView 并在我的应用程序中旋转它们后，在 ImageView 上设置 OnClickListener 。但是当我在屏幕上按下 ImageView 时，onClick 方法无法正常工作。如果我在 ImageView 的原始位置按屏幕，它就会起作用。我想在旋转动画后的最终位置提前制作其他ImageView，但我不知道如何使ImageView具有倾斜的布局。我正在等待您的帮助......

谢谢。

Android 将再次运行 onDestroy() 和 onCreate() 来执行方向更改。为了避免这种情况，请尝试在您的 Activity 中实现 onConfigurationChanged() 并且不要忘记在您的 AndroidManifest.xml 中允许“android:config=”orientation”
