我正在更新我的应用中的导航抽屉。我想在Gmail应用程序中添加部分分隔符。我该如何添加它们?只需将它们添加为视图,这是一种简单的方法。但是,我想知道,这是正确的方法吗?
Gmail应用:
现在,我正在使用带有标题视图的列表视图。
我当前的xml:
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<include
android:id="@+id/toolbar"
layout="@layout/toolbar_with_spinner" />
<FrameLayout
android:id="@+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</FrameLayout>
</LinearLayout>
<ListView
android:id="@+id/listview_drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="@color/white"
android:choiceMode="singleChoice"
android:divider="@null"
android:dividerHeight="0dp" />
</android.support.v4.widget.DrawerLayout>
实现Gmail导航等功能的正确方法是什么?

使用菜单资源而不是listview。菜单中的组标签创建分隔线
menu_drawer
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single"
>
<item
android:id="@+id/id1"
android:icon="@drawable/icon1"
android:title="@string/title1"
/>
<item
android:id="@+id/id2"
android:icon="@drawable/icon2"
android:title="@string/title2"
/>
<item
android:id="@+id/id3"
android:icon="@drawable/icon3"
android:title="@string/title3"
/>
</group>
<group android:checkableBehavior="none"
android:id="@+id/menu_nav_temp_gid"
>
<item
android:id="@+id/settings"
android:icon="@drawable/ic_settings"
android:title="@string/settings" />
</group>
</menu>
在导航视图中链接菜单资源
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/ac_hs_drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<include layout="@layout/layout_home_screen" />
<android.support.design.widget.NavigationView
android:id="@+id/ac_hs_nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="@layout/layout_nav_header"
app:menu="@menu/menu_drawer"
>
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>

我使用headerview和footerview将图像添加到顶部,将分隔符添加到底部。分隔符是视图。
drawer_list_footer_divider.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="bottom"
android:background="@android:color/white"
android:orientation="vertical" >
<View
android:id="@+id/left_viewline"
android:layout_width="match_parent"
android:layout_height="1dp"
android:layout_marginTop="10dp"
android:background="?android:attr/listDivider" />
</LinearLayout>
drawer_list_footer_view.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_gravity="bottom"
android:background="@android:color/white"
android:gravity="center_vertical"
android:orientation="horizontal"
android:paddingLeft="5dp"
android:paddingRight="5dp" >
<ImageView
android:id="@+id/imageView_settings"
android:layout_width="25dp"
android:layout_height="25dp"
android:contentDescription="@string/empty"
android:src="@drawable/ic_action_settings" />
<TextView
android:id="@+id/textView_settings"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="end"
android:padding="10dp"
android:singleLine="true"
android:text="@string/action_settings" />
</LinearLayout>
在我的代码中:
private void setUpHeaderAndFooter() {
LayoutInflater inflater = getLayoutInflater();
View header = (View) inflater.inflate(R.layout.drawer_list_header_view,
mDrawerList, false);
mDrawerList.addHeaderView(header, null, false);
View footer_divider = (View) inflater.inflate(
R.layout.drawer_list_footer_divider, null, false);
mDrawerList.addFooterView(footer_divider, null, false);
// This view is Settings view
View footer = (View) inflater.inflate(R.layout.drawer_list_footer_view,
mDrawerList, false);
footer.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if (mDrawerLayout.isDrawerOpen(Gravity.LEFT)) {
mDrawerLayout.closeDrawer(Gravity.LEFT);
}
if (android.os.Build.VERSION.SDK_INT < 11) {
startActivity(new Intent(MainActivity.this,
Settings1Activity.class)
.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT));
} else {
startActivity(new Intent(MainActivity.this,
Settings2Activity.class)
.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT));
}
}
});
mDrawerList.addFooterView(footer, null, true);
}

将DrawerLayout中的NavigationView用作其第二个子节点。在菜单中插入项目并将菜单属性应用于NavigationView以在导航抽屉中显示列表项。 然后,您可以将组ID分配给要放置在其中的菜单项,这将自动创建分隔符。 如需更广泛的解释,请点击:
