如何在 Android 中正确覆盖 dispatchKeyEvent

Question

我明白了

D/InputEventConsistencyVerifier( 2144): KeyEvent: ACTION_UP but key was not down.`
D/InputEventConsistencyVerifier( 2144): in com.android.internal.policy.impl.PhoneWindow$DecorView@41689658

当我尝试在我的活动中执行此操作时出现警告：

@Override
public boolean dispatchKeyEvent(KeyEvent event) {
    if ((/*some boolean checks*/) && (event.getAction() == KeyEvent.ACTION_DOWN)) {
            /*some custom functions*/
            return true;
        }
    }
    return super.dispatchKeyEvent(event);
}

在活动级别覆盖dispatchKeyEvent 的正确方法是什么？这些警告好吗？视图的onKeyUp和onKeyDown要不要做相应的修改？

试试这个

@Override
public boolean dispatchKeyEvent(KeyEvent event) {
    if (event.getKeyCode() == KeyEvent.KEYCODE_ENTER) {
        if (event.getAction() == KeyEvent.ACTION_UP){

         enter();

            return true;
    }}
    return super.dispatchKeyEvent(event);
};
