android - 旋转动画后如何在ImageView上设置OnClickListener

Question

我想在我使用 addView 方法动态创建它们并在我的应用程序中旋转它们之后，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 的原始位置按下屏幕，它就会工作。我想在旋转动画后的最终位置提前制作其他ImageView，但我不知道如何制作具有倾斜布局的ImageView。我在等你的帮助......

谢谢。

Android 将再次运行 onDestroy() 和 onCreate() 以执行方向更改。为避免这种情况，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"
