解决ScrollView中的ListView无法显示全

问题描述：

ListView加入到ScrollView中之后，发现只能显示其中一条，具体原因得看一下源代码。现在先贴一下方案

（转自:http://blog.csdn.net/hitlion2008/article/details/6737459）

Example:

public class ViewsUtils {  

    public static void setListViewHeightBasedOnChildren(ListView listView) {  

        ListAdapter listAdapter = listView.getAdapter();   

        if (listAdapter == null) {  

            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);  

    }  

}  

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

如何使用？

设置完Adapter之后调用方法重新计算

        ListView listView = (ListView)findViewById(R.id.listView);

        listView.setAdapter(new TestAdapter(this,names));

        // 使用ViewsUtils重新计算每一个Item的高度，然后重新setListView的LayoutParams

        ViewsUtils.setListViewHeightBasedOnChildren(listView);

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }
