Android：防止过快点击造成多次事件 问题

自定义一个NoDoubleClickListener,继承自OnClickListener：
public abstract class NoDoubleClickListener implements View.OnClickListener {
    public static final int MIN_CLICK_DELAY_TIME = 1000;
    private long lastClickTime = 0;

    @Override
    public void onClick(View v) {
        long currentTime = Calendar.getInstance().getTimeInMillis();
        if (currentTime - lastClickTime > MIN_CLICK_DELAY_TIME) {
            lastClickTime = currentTime;
            onNoDoubleClick(v);
        }
    }

    protected abstract void onNoDoubleClick(View v);

}
在设置点击事件时用NoDoubleClickListener替换OnClickListener，并且实现方法onNoDoubleClick替换onClick即可：
 btnPay.setOnClickListener(new NoDoubleClickListener() {
          @Override
          protected void onNoDoubleClick(View v) {
              startPay();
          }
      });

    }
