您可以使用此代碼不允許多個速度點擊，而不是你onclicklistener。

public abstract class SingleClickListener implements View.OnClickListener { 
    private static final long THRESHOLD_MILLIS = 500L; 
    private long lastClickMillis; 

    @Override 
    public void onClick(View v) { 
     long now = SystemClock.elapsedRealtime(); 
     if (now - lastClickMillis > THRESHOLD_MILLIS) { 
      onClicked(v); 
      lastClickMillis = 0; 
     } else { 
      lastClickMillis = now; 
     } 
    } 

    public abstract void onClicked(View v); 
} 

，而不是正常onclicklistener使用這

stage1_nxt.setOnClickListener(new SingleClickListener() {
