推荐答案

你也许在这里做什么是创建一个新的看法尤其是对列表视图（称之为ListViewFlinger或东西）。然后在此视图，覆盖其的onTouchEvent方法，并把一些code。在那里确定一个滑动的手势。一旦你的幻灯片的姿态，火onSlideComplete事件（你必须作出这样的监听器）的voialla，你一个ListView采用滑盖激活的内容。

What you might what to do here is create a new view especially for the list view (call it ListViewFlinger or something). Then in this view, override its onTouchEvent method and place some code in there to determine a slide gesture. Once you have the slide gesture, fire a onSlideComplete event (you'll have to make that listener) an voialla, you a ListView with slide activated content.

float historicX = Float.NaN, historicY = Float.NaN;
static final TRIGGER_DELTA = 50; // Number of pixels to travel till trigger

@Override public boolean onTouchEvent(MotionEvent e) {

    switch (e.getAction()) {
    case MotionEvent.ACTION_DOWN:
        historicX = e.getX();
        historicY = e.getY();
        break;
    case MotionEvent.ACTION_UP:
        if (e.getX() - historicX > -TRIGGER_DELTA) {
            onSlideComplete(Direction.LEFT);
            return true;
        }
        else if (e.getX() - historicX > TRIGGER_DELTA)  {
            onSlideComplete(Direction.RIGHT);
            return true;
        } break;
    default:
        return super.onTouchEvent(e);
    }
}

enum Direction {
    LEFT, RIGHT;
}

interface OnSlideCompleteListener {
    void onSlideComplete(Direction dir);
}
