android _scrollview嵌套listview出现高度显示不全解决方案

只要在工具类里写上这一段代码：
/**
	 * scrollview嵌套listview显示不全解决
	 * @param listView
	 */
	public static void setListViewHeightBasedOnChildren(ListView listView) {
		ListAdapter listAdapter = listView.getAdapter();
		if (listAdapter == null) {
			// pre-condition
			return;
		}

		int totalHeight = 0;
		for (int i = 0; i < listAdapter.getCount(); i++) {
			View listItem = listAdapter.getView(i, null, listView);
			listItem.measure(0, 0);
			totalHeight += listItem.getMeasuredHeight();
		}

		ViewGroup.LayoutParams params = listView.getLayoutParams();
		params.height = totalHeight
				+ (listView.getDividerHeight() * (listAdapter.getCount() - 1));
		listView.setLayoutParams(params);
	}

 

然后在setdapter以后调用该方法就解决问题了。
