解决多个listview或者gridview与scrollview滚动条冲突的问题

RT

根据adapter获取到每一项item的高度，再动态设置listview或者gridview的高度。

public class Utility {
		public void setListViewHeightBasedOnChildren(ListView listView) {
			ListAdapter listAdapter = listView.getAdapter();
			if (listAdapter == null) {
				return;
			}
			int totalHeight = 0;
			int count = listAdapter.getCount();
			for (int i = 0; i < count; i++) { // listAdapter.getCount()返回数据项的数目
				View listItem = listAdapter.getView(i, null, listView);
				listItem.measure(0, 0); // 计算子项View 的宽高
				totalHeight += listItem.getMeasuredHeight(); // 统计所有子项的总高度
			}
			ViewGroup.LayoutParams params = listView.getLayoutParams();
			params.height = totalHeight
					+ (listView.getDividerHeight() * (count - 1));
			// listView.getDividerHeight()获取子项间分隔符占用的高度
			// params.height最后得到整个ListView完整显示需要的高度
			listView.setLayoutParams(params);
		}

		public void setGridViewHeightBasedOnChildren(GridView gridView) {
			ListAdapter listAdapter = gridView.getAdapter();
			if (listAdapter == null) {
				return;
			}
			int totalHeight = 0;
			int count = listAdapter.getCount();
			View listItem = listAdapter.getView(0, null, gridView);
			listItem.measure(0, 0); // 计算子项View 的宽高
			totalHeight = listItem.getMeasuredHeight() + 10; // 统计所有子项的总高度
			int yu = count % 4;
			ViewGroup.LayoutParams params = gridView.getLayoutParams();
			if (yu > 0) {
				params.height = (count - yu) / 4 * (totalHeight + 10)
						+ totalHeight;
			} else {
				params.height = count / 4 * totalHeight + (count / 4 - 1) * 10;
			}
			gridView.setLayoutParams(params);
		}
	}

我这儿gridview是显示4列，所以获取高度的时候算法是这样，可以根据需要更改。

 

用法在listview.setadapter之后，调用此方法中的其中某一个.

new Utility().setListViewHeightBasedOnChildren(AppList);
