有时候我们要动态修改listview中item某一项的属性（例如实现全选或者单选后imageview的效果）

1 例如如下的布局绝对布局中两个item

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@+id/since_the_number_relativeLayout_select"    android:layout_width="match_parent"    android:layout_height="50dp">    <TextView        android:id="@+id/since_the_number_select_tv"        android:layout_width="wrap_content"        android:layout_height="50dp"        android:layout_marginLeft="15dp"        android:gravity="center"        android:text="1号桩"        android:textColor="#FF333333"        android:textSize="16dp" />    <ImageView        android:id="@+id/since_the_number_select_iv"        android:layout_width="wrap_content"        android:layout_height="match_parent"        android:layout_alignParentRight="true"        android:layout_centerVertical="true"        android:layout_marginRight="15dp"        android:src="@drawable/list_btn_default" /></RelativeLayout>

1 设置listview的点击事件后实现单选并改变此item项中imageview的状态

下面是实现循环遍历item 并得到里面的控件问题

listGroupSataion.setOnItemClickListener(new AdapterView.OnItemClickListener() {    @Override    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {        RelativeLayout relativeLayout = (RelativeLayout) view.findViewById(R.id.since_the_number_relativeLayout_select);        for (int i = 0; i < listGroupSataion.getChildCount(); i++) {            View viewChild = listGroupSataion.getChildAt(i);            RelativeLayout layMain = (RelativeLayout) viewChild.findViewById(R.id.since_the_number_relativeLayout_select);            ImageView iv = (ImageView) layMain.findViewById(R.id.since_the_number_select_iv);            iv.setImageResource(R.drawable.list_btn_default);        }        ImageView iv = (ImageView) relativeLayout.findViewById(R.id.since_the_number_select_iv);        iv.setImageResource(R.drawable.list_btn_selected);        sineTheNumberListener.onSineTheNumberClick(list.get(position));    }});
假如布局过于复杂 ，那就必须进行一步一步的解析找到item
