防止按钮短时间内重复点击

类的主内容：

public class EnableDelayUtil {
private static Handler handler = new Handler();
    private static ArrayList<Runnable> myRunnableList = new ArrayList<>();
    private static ArrayList<View> viewList = new ArrayList<>();


    public static void setDelayed(final View v) {
//            handler=new Handler();
        final Runnable myRunnable = new Runnable() {

@Override
            public void run() {
// TODO Auto-generated method stub
                v.setEnabled(true);
                viewList.remove(v);
                myRunnableList.remove(this);
            }
        };
        myRunnableList.add(myRunnable);
        viewList.add(v);

        v.setEnabled(false);

        handler.postDelayed(myRunnable, 2000);
    }

public static void remove() {
if (!myRunnableList.isEmpty()) {
for (Runnable myRunnable : myRunnableList) {
if (myRunnable != null) {
handler.removeCallbacks(myRunnable);
                }
            }
myRunnableList.clear();
        }
    }
}

使用方法：

在需要防止重复点击的地方调用

EnableDelayUtil.setDelayed(view) ，

然后在所处activity的结束处调用EnableDelayUtil.remove()即可。
