资源目录values下新建资源文件：
ids.xml:

<?xml version="1.0" encoding="utf-8"?> ...

实现原理：给Button设置名为last_click_time的tag标签并存储上一次点击的时间戳，在一定的时间间隔内只取第一次点击事件。如此， Button会随着界面的销毁而被释放，因而它的名为last_click_time的tag标签存储所占用的内存也会被释放回收。

使用起来那就是更简单了
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (AntiShakeUtils.isInvalidClick(v))
return;
// TODO: 2018/7/1
}
});

你还可以自定义有效点击的时间间隔：
if (AntiShakeUtils.isInvalidClick(v, 800))
return;

用过之后，从此不罢手！
