This tag and its children can be replaced by one <TextView/> and a compound drawable

 <?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="wrap_content"
     android:orientation="horizontal" >

     <ImageView
         android:src="@drawable/ic_launcher"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:contentDescription="@drawable/ic_launcher"/>

     <TextView
         android:id="@+id/list_item_textview"
         android:layout_width="wrap_content"
         android:layout_height="fill_parent"
         android:paddingLeft="20dp"/>

 </LinearLayout>

如果图片是直接引用drawable中的图片资源，可以直接在TextView中定义，

可直接替换为：

 <?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="wrap_content"
     android:orientation="horizontal" >

     <TextView
         android:id="@+id/list_item_textview"
         android:layout_width="wrap_content"
         android:layout_height="fill_parent"
         android:drawableLeft="@drawable/ic_launcher"
         android:drawablePadding="20dp"/>

 </LinearLayout>
