问题是android.support.v4.view.ViewCompat没有在新的androidx包结构中实现View.OnUnhandledKeyEventListener，并且只在支持的库结构中从API28开始实现它(至少在28.0.0版本中)。因此，该警告出现在API <28的设备上，而不会出现在这些>=28上。

这是来自支持包structure:##的ViewCompat.class类中的相关代码

@RequiresApi(28)私有静态类OnUnhandledKeyEventListenerWrapper实现OnUnhandledKeyEventListener {私有ViewCompat.OnUnhandledKeyEventListenerCompat mCompatListener；

代码语言：javascript
运行
复制
OnUnhandledKeyEventListenerWrapper(ViewCompat.OnUnhandledKeyEventListenerCompat listener) {
    this.mCompatListener = listener;
}

public boolean onUnhandledKeyEvent(View v, KeyEvent event) {
    return this.mCompatListener.onUnhandledKeyEvent(v, event);
}

} ##
