Android TwoLineListItem继承android.widget.RelativeLayout.由两个子视图组合而成，通常用在ListView中。
它需要两个TextView（ID值为text1，text2），还有一个可选的第三个VIew(ID值为selectedIcon)。
<?xml version="1.0" encoding="utf-8"?>
<TwoLineListItem xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ImageView
android:id="@+id/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@android:drawable/presence_offline" />
<TextView
android:id="@android:id/text1"
android:layout_marginTop="1dip"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="@id/icon"
android:textSize="15dip"
android:text="ssssssssssssssssssssssss"
android:textStyle="bold" />
<TextView
android:id="@android:id/text2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@android:id/text1"
android:layout_alignLeft="@android:id/text1"
android:paddingBottom="4dip"
android:includeFontPadding="false"
android:textSize="15dip"
android:text=""
android:textStyle="normal" />
<ImageView
android:id="@android:id/selectedIcon"
android:layout_marginTop="9dip"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_marginRight="7dip"
android:src="@android:drawable/sym_action_call" />
</TwoLineListItem>
