推荐答案
正如 ALFlanagan 在评论中提到的问题是 android.support.v4.view.ViewCompat 没有实现 View.OnUnhandledKeyEventListener 在新的 androidx 包结构中，并且仅在支持库结构中的 API 28(至少在版本 28.0.0 中)开始实现它.因此警告出现在 API <28 的设备上，而不出现在那些 >=28 的设备上.
As A.L.Flanagan mentioned in a comment the problem is that android.support.v4.view.ViewCompat does not implement View.OnUnhandledKeyEventListener in the new androidx package structure and only implements it starting on API 28 in the support lib structure (at least in version 28.0.0). Therefore the warning appears on devices with API <28 and does not appear on those >=28.
这是支持包结构中ViewCompat.class类中的相关代码:
This is the related code in the ViewCompat.class class from the support package structure:
@RequiresApi(28)
private static class OnUnhandledKeyEventListenerWrapper implements OnUnhandledKeyEventListener {
private ViewCompat.OnUnhandledKeyEventListenerCompat mCompatListener;
OnUnhandledKeyEventListenerWrapper(ViewCompat.OnUnhandledKeyEventListenerCompat listener) {
this.mCompatListener = listener;
}
public boolean onUnhandledKeyEvent(View v, KeyEvent event) {
return this.mCompatListener.onUnhandledKeyEvent(v, event);
}
}
我想不出任何简单的方法来解决这个警告.
I can not think about any easy fix to solve this warning.
