你需要使用像LinearLayout或Relative这样的布局...

<LinearLayout
android:id="@+id/mainLinearLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >

<ImageView
    android:id="@+id/imageView"
    android:layout_width="48dp"
    android:layout_height="48dp"
    android:src="@drawable/ic_launcher"
    android:contentDescription="@string/app_name"/>

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceListItemSmall"
    android:gravity="center_vertical"
    android:paddingLeft="16dp"
    android:paddingRight="16dp"
    android:textColor="#fff"
    android:background="?android:attr/activatedBackgroundIndicator"
    android:minHeight="?android:attr/listPreferredItemHeightSmall"/>
</LinearLayout>
