安卓设置双击的监听器

public class OnDoubleClickListener implements View.OnTouchListener {

    private int count = 0;//点击次数
    private long firstClick = 0;//第一次点击时间
    private long secondClick = 0;//第二次点击时间
    /**
     * 两次点击时间间隔，单位毫秒
     */
    private final int totalTime = 1000;
    /**
     * 自定义回调接口
     */
    private DoubleClickCallback mCallback;

    public interface DoubleClickCallback {
        void onDoubleClick();
    }

    public OnDoubleClickListener(DoubleClickCallback callback) {
        super();
        this.mCallback = callback;
    }

    /**
     * 触摸事件处理

     * @param event
     * @return
     */
    @Override

        if (MotionEvent.ACTION_DOWN == event.getAction()) {//按下
            count++;

                firstClick = System.currentTimeMillis();//记录第一次点击时间
            } else if (2 == count) {
                secondClick = System.currentTimeMillis();//记录第二次点击时间
                if (secondClick - firstClick < totalTime) {//判断二次点击时间间隔是否在设定的间隔时间之内
                    if (mCallback != null) {
                        mCallback.onDoubleClick();

        findViewById(R.id.fragment).setOnTouchListener(new OnDoubleClickListener(new OnDoubleClickListener.DoubleClickCallback() {

                Logs.i(TimeUtil.long2time(System.currentTimeMillis(), Constant.formatPhoto));

fragment为被监听的控件
