scrollView中实现listView的解决方法
scrollView中实现listView的解决方法
1.自定义view，采用继承LinearLayout的方式
2.继承Adapter，本例中采用两种方式进行演示：
1.ArrayAdapter 2.BaseAdapter
先是第一种ArrayAdapter:
main.xml 主布局xml
test.xml
第二种BaseAdapter:
主布局xml man.xml
test.xml
事件操作，并通过下标得到数据源：

事件操作，并通过下标得到数据源：
lv.setOnclickLinstener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(
BlueToothActivity.this,
Layoutadpater.get(Integer.parseInt(v.getTag()
.toString()), "key_name"), 1000).show();
}
});
lv.setAdapter(Layoutadpater);
