刷卡时ViewFlipper不工作。如果我把列表视图其他一些观点相反，翻转正常工作。是否有任何其他codeI应该增加对一个ListView？而内部视图的鳍状肢滚动视图也不会为我工作:( 这是我的XML code

滚动没有生效，因为你已经overrided手势，所以，还需要采取手动滚动效果的情况下。
ViewFlipper is not working when swiping. If i put some other view instead of list view, flipping works fine. Is there any other code i should add for a listview? And scroll view inside view flipper also not working for me :( This is my xml code
<?xml version="1.0" encoding="utf-8"?>
<ViewFlipper xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/vf"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ListView
android:id="@+id/list1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ListView
android:id="@+id/list2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</LinearLayout>
</ViewFlipper>
This is my class code.

Override dispatchTouchEvent instead of onTouchEvent makes both scroll view and gesture working fine.
@Override
public boolean dispatchTouchEvent(MotionEvent event) {
super.dispatchTouchEvent(event);
return gestureDetector.onTouchEvent(event);
}
解决方案
Scrolling is not taking effect, as you have already overrided gestures, so, you also need to take scroll effect manually, in the case.
