Question

您好我一直在研究这个问题。我正在使用GestureListener和ViewFlipper在两个不同的WebView之间滑动。一个webview是聊天，另一个是flash流。蒸汽是全屏的，当我滑动时它不会离开屏幕。聊天滑动但是当我向后滑动时它不会返回。当我改变方向时，我可以看到下面的聊天。请帮忙。

手势正常，但视频无法移动。我怎么能把它移到后面？

事实证明，Flash视频播放器是某种无法由java控制的父级。通过从布局持有者中移除视图，可以实现滑动的效果。经过了大量的试验和错误，但它确实有效！

    @Override
public void onSwipe(int direction) {
    // TODO Auto-generated method stub

    switch (direction) {

    case SimpleGestureFilter.SWIPE_RIGHT:
        if (flipView.getDisplayedChild() == 1) {
            //flipView.setDisplayedChild(1);
            setStreamView();
            holder.addView(streamView);
        }
        break;

    case SimpleGestureFilter.SWIPE_LEFT:
        if (flipView.getDisplayedChild() == 0) {
            //flipView.setDisplayedChild(0);
            setChatView();
            holder.removeAllViews();
        }
        break;
    }

Flash视频不会使用ViewFlipper滑动
