android - 为抽屉布局创建页眉？

Question

我正在尝试为我的 DrawerLayout 创建一个页眉。当我添加 ImageView 确实会引发异常并停止应用程序。

我该怎么做？

Answer 1

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);
