Android SimpleAdapter自定义格局显示本地资源

如果直接继承ListAcitivty，则不需要自定义ListView，下面的是列表项单项显示格式

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
??? android:layout_width="fill_parent"
??? android:layout_height="fill_parent"
??? android:orientation="horizontal" >

??? <ImageView
??????? android:id="@+id/img"
??????? android:layout_width="wrap_content"
??????? android:layout_height="wrap_content"
??????? android:layout_margin="3px"
??????? />
??? <LinearLayout
??????? android:layout_width="fill_parent"
??????? android:layout_height="wrap_content"
??????? android:orientation="vertical"
??????? >
??????? <TextView
??????????? android:id="@+id/title"
??????????? android:layout_width="fill_parent"
??????????? android:layout_height="wrap_content"
??????????? android:textSize="16sp"
??????????? />
??????? <TextView
??????????? android:id="@+id/info"
??????????? android:layout_width="fill_parent"
??????????? android:layout_height="wrap_content"
??????????? android:textSize="10sp"
??????????? />
??? </LinearLayout>

</LinearLayout>
