<?xml version="1.0" enCoding="utf-8"?><linearLayout    xmlns:androID="http://schemas.androID.com/apk/res/androID"    androID:orIEntation="vertical"    androID:layout_wIDth="fill_parent"    androID:layout_height="fill_parent" >    <ListVIEw        androID:ID="@androID:ID/List"        androID:layout_wIDth="fill_parent"        androID:layout_height="fill_parent"        androID:drawSelectorOntop="false"    /></linearLayout>

解决方法:

您正在寻找的是列表项单击侦听器.你可以尝试下面的lv.setonItemClickListener就是你的例子.

ListVIEw.setonItemClickListener(new OnItemClickListener() {  @OverrIDe  public voID onItemClick(AdapterVIEw<?> parent, VIEw vIEw,    int position, long ID) {    Toast.makeText(getApplicationContext(),      "Click ListItem Number " + position, Toast.LENGTH_LONG)      .show();  }}); 

按照这个基本example

并且没有像onClick到ArrayList那样,为视图设置了点击.
