ScrollView中使用ListView-优快云博客

由于scrollview和listview不能直接共存，在scrollview中直接使用lsitview的话只会显示一个条目，要使他们共存，

据我所知，有三种方法：

1。如果listview的高度是一定的话，可以重写一个listview在onmesure方法里设定固定高度，如下代码：

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(MeasureSpec.UNSPECIFIED, 0) );
int childHeight = getMeasuredHeight() - (getListPaddingTop() + getListPaddingBottom() + getVerticalFadingEdgeLength() * 2);
int fullHeight = getListPaddingTop() + getListPaddingBottom() + childHeight*(getCount());
setMeasuredDimension(getMeasuredWidth(), fullHeight); }

2.如果listview中的高度不是固定的，可以在初始化完listview后设置listview的高度。可以使用以下函数：

public void setListViewHeightBasedOnChildren(ListView listView) {
SettingListAdapter listAdapter = (SettingListAdapter) listView.getAdapter();
if (listAdapter == null) {
return;
}
int totalHeight = 0;
for (int i = 0; i < listAdapter.getCount(); i++) {
View listItem = listAdapter.getView(i, null, listView);
if(listItem != null){
listItem.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
listItem.measure(MeasureSpec.UNSPECIFIED, MeasureSpec.UNSPECIFIED);
totalHeight += listItem.getMeasuredHeight();
}
}
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1))
+ listView.getPaddingTop() + listView.getPaddingBottom();
listView.setLayoutParams(params);
}
