刷卡检测列表视图中的每一行 [英] Swipe detection for each row of listview

问题描述

予有视频位于SD卡的列表。在这一点上，我只需要在列表视图中的每一行创建的手势或刷卡检测帮助。由于这个问题计算器机器人 - 基本手势检测，我实现了在列表视图的手势。现在，当用户扫描在正确的方向或向左方向很容易检测。但这种姿态是整个列表视图。我只是想知道我怎样才能实现这个刷卡检测单个行。例如，现在的应用程序，使一个打印右刷卡，左刷卡举杯。我只是想让它像右轻扫上排1号，左刷卡就行3号等。我希望我的问题是显而易见的。

I have a list of videos located in the sd-card. At this point, I just need help in creating gestures or swipe detection for each row in the list view. Thanks to this question at stackoverflow Android - basic gesture detection, I implemented the gesture on the listview. It now easily detects when the user swipes in the right direction or left direction. But this gesture is for the entire listview. I just want to know how can I implement this swipe detection for individual rows. For example, the application now makes a toast that prints "Right Swipe", "Left Swipe". I just want to make it like "Right Swipe on row no 1", "Left Swipe on Row no 3" etc.. I hope my question was clear.

期待一些有用的回复。 谢谢

Looking forward to some helpful replies. Thanks

推荐答案

看看到这个答案并使用<一个href="http://developer.android.com/reference/android/widget/AbsListView.html#pointToPosition%28int,%20int%29"相对=nofollow>在 onFling 事件pointToPosition 方法

Take a look into this answer and use pointToPosition method inside onFling Event

@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
    try {
        Toast.makeText( listAdapter.getItem( listView.pointToPosition(Math.round(e1.getX()), Math.round(e1.getY())).toString());
        return super.onFling();
    } catch( Exception e ) {
        // do nothing
    }
}
