想要实现的效果(抽屉上的listview上面每个项都有一个图标)

左侧抽屉的实现问题

下面是我的布局文件(目前还不知道怎么加载另外的布局文件,所以左侧抽屉和中间部分的布局都在一个文件)

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                 >
    <android.support.v4.widget.DrawerLayout
            android:id="@+id/drawer_layout"
            android:layout_width="match_parent"
            android:layout_height="match_parent" >
        <!-- The main content view -->
        <FrameLayout
                android:id="@+id/content_frame"
                android:layout_width="match_parent"
                android:layout_height="match_parent" >
            <ListView
                    android:id="@+id/show"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    />
            <ImageView
                    android:id="@+id/bimg"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    />
            <TextView
                    android:id="@+id/shuosha"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    />
        </FrameLayout>
        <!-- The navigation drawer         -->
        <ListView
                android:id="@+id/left_drawer"
                android:layout_width="240dp"
                android:layout_height="match_parent"
                android:layout_gravity="start"
                android:background="#111"
                android:choiceMode="singleChoice"
                android:divider="@android:color/transparent"
                android:dividerHeight="0dp" />
    </android.support.v4.widget.DrawerLayout>


</RelativeLayout>

下面是Activity文件(参照了一些网上的例子):
