我创建了一个导航抽屉菜单，并在布局中添加了GridView。添加GridView后，导航抽屉菜单滚动功能无效。这是我的main.xml代码：
<?xml version="1.0" encoding="utf-8"?>
<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/drawerlayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFFFFF">
<FrameLayout
android:id="@+id/mainContent"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
<ListView
android:background="#FFFFFF"
android:divider="@android:color/darker_gray"
android:choiceMode="singleChoice"
android:dividerHeight="0.1dp"
android:id="@+id/drawerList"
android:layout_width="200dp"
android:layout_height="wrap_content"
android:layout_gravity="start">

<GridView

当我们构建自定义导航时，导航抽屉线性布局将视图改为前面，即使前面显示的也是 Z顺序树。这就是我们在另一个组件中添加的原因在导航抽屉所属的main.xml文件中，它不会滚动和单击。
所以为了解决这个问题，我们应该将导航抽屉列表作为Activity的前视图。为此，我们应该在使用自定义导航抽屉时添加以下代码。
listview.bringToFront();
drawerlayout.requestLayout();
listview.setOnScrollListener(new OnScrollListener() {
@Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
// TODO Auto-generated method stub
if (scrollState == SCROLL_STATE_IDLE) {
listview.bringToFront();
drawerlayout.requestLayout();
}
}
@Override
public void onScroll(AbsListView view, int firstVisibleItem,
int visibleItemCount, int totalItemCount) {
// TODO Auto-generated method stub
}
});
现在抽屉列表将启动Scroll，OnItemClickListener将开始为DrawerList的每个元素工作........

我在抽屉布局下面有线性和相对布局时遇到了同样的问题。我设法通过在“抽屉布局”之前定义“线性和相对布局”来解决此问题。
