创建headerledout标题？

Question

我正在尝试为DrawerLayout创建一个Header。当我添加<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/dl" android:background="@drawable/splash" > <FrameLayout android:id="@+id/fl" android:layout_width="match_parent" android:layout_height="match_parent" > </FrameLayout> <LinearLayout android:layout_width="250dp" android:layout_height="match_parent" android:orientation="vertical"> <ImageView android:layout_width="150dp" android:layout_height="150dp" android:src="@drawable/logo" /> <ListView android:id="@+id/lv" android:layout_width="250dp" android:layout_height="match_parent" android:choiceMode="singleChoice" android:divider="#DCDCDC" android:paddingLeft="5dp" android:paddingRight="5dp" android:dividerHeight="1dp" android:background="@color/action_bar" android:layout_gravity="start" > </ListView> </LinearLayout> </android.support.v4.widget.DrawerLayout> 时会抛出异常并停止应用。

我怎么能这样做？

试试这个：

<LinearLayout
    android:id="@+id/navdrawer"
    android:layout_width="250dp"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <ImageView
       ...
        />
    <ListView
       ...
        >
    </ListView>
</LinearLayout>

和

LinearLayout ll = (LinearLayout) findViewById(R.id.navdrawer);

...

dl.isDrawerOpen(ll);

...

dl.closeDrawer(ll);
