防止按钮连续点击 

其实实现很简单 

共通方法： 

public class Utils {
    private static long lastClickTime;
    public static boolean isFastDoubleClick() {
        long time = System.currentTimeMillis();
        long timeD = time - lastClickTime;
        if ( 0 < timeD && timeD < 500) {
            return true;
        }
        lastClickTime = time;
        return false;
    }
}

    

按钮点击时： 

public void onClick(View v) {
    if (Utils.isFastDoubleClick()) {
        return;
    }
}

这样所有按钮在500毫秒内不能同时起效。 

针对调时间做了一点改进 

long timeD = time - lastClickTime; 

0 < timeD
