【问题描述】：

我是 android 新手，所以我制作了导航抽屉，但我想更改内部列表的视图或内容

当我们点击抽屉内的这个类别时THis is first page link

这是另一个页面this is second page link，它会在不关闭抽屉的情况下出现。如果您能提供任何关于此的逻辑，请告诉我

这是我制作的第二个列表但是我希望当我单击导航抽屉的任何项目而不关闭它时显示此列表

这是我的 xml

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/drawer_layout"
    android:layout_
    android:layout_>

    <!-- The first child in the layout is for the main Activity UI-->

        android:background="#ffffffff">

        <ImageView

            android:layout_centerHorizontal="true"/>

    </RelativeLayout>

    <!-- Side navigation drawer UI -->
    <FrameLayout

        android:layout_
        android:layout_ />

    <ExpandableListView

</android.support.v4.widget.DrawerLayout>

【参考方案1】：

我已经解决了我的问题，只更改了要在视图内设置为适配器的数组

            listAdapter = new ExpandableListAdapter(MainActivity.this, listDataHeader1, listDataChild1);

            // setting list adapter
            expListView.setAdapter(listAdapter);

这是我在点击监听器内单击左侧抽屉中的任何项目时所写的内容。我想通过单击其中的任何项目来更改导航抽屉的项目。但是在点击后退按钮时，前一个项目会被加载，它不能关闭我想要的抽屉
