雙擊Cocos2d Android JAVA

Question

嘗試在Android（Cocos2d Framework）中檢測雙擊。 我究竟做錯了什么？

在ccTouchesEnded中，我有：

public boolean ccTouchesEnded(MotionEvent event) {

    touchTapCount++;
    Lg("Tapcount : " + touchTapCount);
    if (touchTapCount == 1) {
        Lg("We're in the 1 thingie!");
        CCDelayTime delayaction = CCDelayTime.action(0.2f);
        CCCallFunc callSelectorAction = CCCallFunc.action(this, "dtreset");
        CCSequence a = CCSequence.actions(delayaction,(CCFiniteTimeAction) callSelectorAction);
        this.runAction(a);
    } else {
        if (touchTapCount ==2){
            Lg("Oh yeah we got double tap!");
        }
    }

而且我有重置者：

public void dtreset(Object Sender){
    Lg("Resetted the TouchTapCount");
    touchTapCount = 0;
}

我的輸出表明該序列根本沒有運行。.因此，只添加了count，在200 ms之后沒有復位... :(

作為解決方案，我決定使用android自己的Handler類。

public boolean ccTouchesEnded(MotionEvent event) {

    touchTapCount++;
    Lg("Tapcount : " + touchTapCount);
    if (touchTapCount == 1) {
        // Very important bit of code..
        // First, we define a Handler and a Runnable to go with it..
        Handler handler = new Handler(Looper.getMainLooper());
        final Runnable r = new Runnable() {
            public void run() {
                // In the runnable, we set the touchTapCount back to 0..
                touchTapCount = 0;
            }
        };
        // Now, execute this handler with a delay of 200ms..
        handler.postDelayed(r, 200);

    } else {
        if (touchTapCount == 2){
            wasdoubletapped = true;
            verifySelectorTypeBeforeRotate(cC, cR, SELECTOR_CROSS);
        }

因此，它的作用是：通過計數抽頭數並在第一次抽頭后200毫秒將該計數重置為零來檢測雙擊。
