Question

您好我在我的recyclerview中使用滑动布局。另外，我想为列表项布局实现单击和双击。如果我使用触摸监听器，我的滑动将无法正常工作。所以我想使用setOnClickListener检测布局的单击和双击。请建议我检测布局的单击和双击。

Answer 1

您好我找到了一个解决方案，单击和双击都适用于使用onSingleTapConfirmed的单一视图，如下所示

  public class OnSwipeTouchListener implements View.OnTouchListener {

private GestureDetector gestureDetector;

public OnSwipeTouchListener(Context c) {
    gestureDetector = new GestureDetector(c, new GestureListener());
}

public boolean onTouch(final View view, final MotionEvent motionEvent) {
    return gestureDetector.onTouchEvent(motionEvent);
}

private final class GestureListener extends GestureDetector.SimpleOnGestureListener {

    private static final int SWIPE_THRESHOLD = 100;
    private static final int SWIPE_VELOCITY_THRESHOLD = 100;

    @Override
    public boolean onDown(MotionEvent e) {
        return true;
    }

    @Override
    public boolean onSingleTapUp(MotionEvent e) {

        return super.onSingleTapUp(e);
    }

    @Override
    public boolean onSingleTapConfirmed(MotionEvent e) {
        onClick();
        return super.onSingleTapConfirmed(e);
    }

    @Override
    public boolean onDoubleTap(MotionEvent e) {
        onDoubleClick();
        return super.onDoubleTap(e);
    }

    @Override
    public void onLongPress(MotionEvent e) {
        onLongClick();
        super.onLongPress(e);
    }

    // Determines the fling velocity and then fires the appropriate swipe event accordingly
    @Override
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
        boolean result = false;
        try {
            float diffY = e2.getY() - e1.getY();
            float diffX = e2.getX() - e1.getX();
            if (Math.abs(diffX) > Math.abs(diffY)) {
                if (Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
                    if (diffX > 0) {
                        onSwipeRight();
                    } else {
                        onSwipeLeft();
                    }
                }
            } else {
                if (Math.abs(diffY) > SWIPE_THRESHOLD && Math.abs(velocityY) > SWIPE_VELOCITY_THRESHOLD) {
                    if (diffY > 0) {
                        onSwipeDown();
                    } else {
                        onSwipeUp();
                    }
                }
            }
        } catch (Exception exception) {
            exception.printStackTrace();
        }
        return result;
    }
}

public void onSwipeRight() {
}

public void onSwipeLeft() {
}

public void onSwipeUp() {
}

public void onSwipeDown() {
}

public void onClick() {

}

public void onDoubleClick() {

}

public void onLongClick() {

}}

然后实现这个类，如下所示，

    btn.setOnTouchListener(new OnSwipeTouchListener(adapter.getContext()) {

        @Override
        public void onClick() {
            super.onClick();
            AlertUtils.showToast(adapter.getContext(),"single tap");
            // your on click here
        }

        @Override
        public void onDoubleClick() {
            super.onDoubleClick();
            // your on onDoubleClick here
        }

        @Override
        public void onLongClick() {
            super.onLongClick();
            // your on onLongClick here
        }

        @Override
        public void onSwipeUp() {
            super.onSwipeUp();
            // your swipe up here
        }

        @Override
        public void onSwipeDown() {
            super.onSwipeDown();
            // your swipe down here.
        }

        @Override
        public void onSwipeLeft() {
            super.onSwipeLeft();
            // your swipe left here.
        }

        @Override
        public void onSwipeRight() {
            super.onSwipeRight();
            // your swipe right here.
        }
    });

快乐编码..

Answer 2

使用以下步骤：

向视图添加触控侦听器
添加全局变量以记录触摸时间
将触控时间与之前的触控时间进行比较。如果差异小于阈值，例如1秒，那么它是双击。

Answer 3

试试这个

int c = 0;
btn.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    c++;
    Handler handler = new Handler();
    Runnable r = new Runnable() {

        @Override
        public void run() {
            c = 0;
        }
    };

    if (c == 1) {
        //Single click
        handler.postDelayed(r, 250);
    } else if (c == 2) {
        //Double click
        c = 0;
        ShowDailog();
    }


}
});
