How to properly override a dispatchKeyEvent in Android
提问by immagonnagetya
I get
我得到
D/InputEventConsistencyVerifier( 2144): KeyEvent: ACTION_UP but key was not down.`
D/InputEventConsistencyVerifier( 2144): in com.android.internal.policy.impl.PhoneWindow$DecorView@41689658
warnings all over when I try to do this in my activity:
当我尝试在我的活动中执行此操作时，到处都是警告：
@Override
public boolean dispatchKeyEvent(KeyEvent event) {
if ((/*some boolean checks*/) && (event.getAction() == KeyEvent.ACTION_DOWN)) {
/*some custom functions*/
return true;
}
}
return super.dispatchKeyEvent(event);
}
What is the correct way of overriding dispatchKeyEventin the activity level? Are these warnings fine? Should I do corresponding changes in the onKeyUpand onKeyDownof my views?
dispatchKeyEvent在活动级别覆盖的正确方法是什么？这些警告好吗？我应该做相应的变化onKeyUp和onKeyDown自己的看法？

Try this
尝试这个
@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);
};
