我在此布局中有多个线性布局。滚动视图在我完全滚动项目时工作，但不在列表视图中。我的列表视图有多个列表项目，它一次只显示一个列表项目谢谢帮助我.....

永远不要在滚动视图中放置列表视图，反之亦然！它在documentation：
中说得很对你永远不应该使用带有ListView的ScrollView，因为ListView负责自己的垂直滚动。最重要的是，这样做会使ListView中的所有重要优化都无法处理大型列表，因为它有效地强制ListView显示其整个项目列表以填充ScrollView提供的无限容器。
答案 1 :(得分：1)
ListView本身是可滚动的。
您不应该将ListView放在ScrollView中，因为ListView类实现了自己的滚动，它只是不接收手势，因为它们都由父ScrollView处理。
http://developer.android.com/reference/android/widget/ScrollView.html
您可以删除滚动视图或在滚动视图外移动列表视图。
您可以查看此链接。谈话在listview上，他们建议不要将listview放在scrollview中。

创建类像这样：
public class Utility {
public static void setListViewHeightBasedOnChildren(ListView listView) {
ListAdapter listAdapter = listView.getAdapter();
if (listAdapter == null) {
// pre-condition
return;
}
int totalHeight = 0;
int desiredWidth = MeasureSpec.makeMeasureSpec(listView.getWidth(), MeasureSpec.AT_MOST);
for (int i = 0; i < listAdapter.getCount(); i++) {
View listItem = listAdapter.getView(i, null, listView);
listItem.measure(desiredWidth, MeasureSpec.UNSPECIFIED);
totalHeight += listItem.getMeasuredHeight();
}
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
listView.setLayoutParams(params);
listView.requestLayout();
}
}
在您想要的位置调用此方法滚动您的列表视图。
Utility.setListViewHeightBasedOnChildren（YourListView）;
适用于您的Reference。
希望这会对你有所帮助。

//requestDisallowInterceptTouchEvent(true);
// use above method to disable listview scroll and enabled scrollview scroll
// to disable listview.requestDisallowInterceptTouchEvent(true);
// to enabled scrollview scroll write as below
// ex: ((MainActivity) context).listview.requestDisallowInterceptTouchEvent(true);
// i have used above things on viewHolder.l1.setOnTouchListener(new View.OnTouchListener()
