防止重复点击按钮方案总结

第一种

按钮按下之后，将按钮置成不可点击，一段时间后设置回来。

代码如下

public static void disabledView(final View v) {
v.setClickable(false);
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
v.setClickable(true);
}
}, 1000);
}

这种方法简单但是个人感觉并不是很好，一个不可点击的按钮给用户的心里就是添堵的。

第二种

允许用户点击，但是不响应频繁的点击。

代码：

long lastClick ;

public void onClick(View v) {

   if (System.currentTimeMillis() - lastClick <= 1000){

          return;      }

      lastClick = System.currentTimeMillis();

这种方法记录了一个上次响应的时间戳，对比一下当前的时间如果小于设置的时间间隔那么就不响应。

这种方法看起来很美，但是一般Button的监听器都是如下的

代码：

    lastClick = System.currentTimeMillis();  <span style="white-space:pre"></span>(v.getId()){            R.id.bth1: xxx  ;               <span style="white-space:pre"></span>break;           R.id.btn2: xxx;        }    }

</pre><span style="font-family:Consolas,Bitstream Vera Sans Mono,Courier New,Courier,monospace"><br /></span><span style="font-family:Consolas,Bitstream Vera Sans Mono,Courier New,Courier,monospace">假如你是像上面代码一般几个BUtton共用一个监听器，就会出现点击 btn1后 在时间间隔内 bth2 是不能响应的。</span></div><div class="line number1 index0 alt2" style="list-style:none;
