我正在尝试在关键事件上实现动画。相同的代码在OnClickListener上工作正常，但在OnKeyListener上则什么也没有发生。甚至Logcat上也没有错误消息。
请帮我解决这个问题。下面是我的代码。请告诉我我错了。

inFromRight.setDuration(500);
inFromRight.setInterpolator(new AccelerateInterpolator());
return inFromRight;
}
private Animation outToLeftAnimation() {
Animation outtoLeft = new TranslateAnimation(

最佳答案
KeyCode取决于您使用的键盘。这意味着对于相同的键，您可能会从不同的键盘获得不同的KeyCode。记住，从documentation，
关于android - OnKeyListener不起作用，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/4878718/
