这是我的主要xml文件:
<?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"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:id="@+id/nav_drawer">
<android.support.design.widget.CoordinatorLayout
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.example.amit.rssreader.MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<include layout="@layout/content_main" />
</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.NavigationView
android:layout_width="wrap_content"
android:layout_height="match_parent"
app:menu="@menu/navigation_menu"
android:layout_gravity="start">
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>
我想把抽屉放在动作栏下面。这不是导航抽屉活动,导航抽屉后来被xml添加。
答案 0 :(得分:1)
我认为这可能会对您有所帮助:
修改xml布局:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.DrawerLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<include layout="@layout/content_main" />
</android.support.design.widget.CoordinatorLayout>
</android.support.v4.widget.DrawerLayout>
</LinearLayout>
在values / styles.xml中为没有工具栏的活动创建主题,并将其应用于AndroidManifest文件中的活动:
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
要使其正常工作,请将活动的onCreate方法设为如下所示:
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
final DrawerLayout drawerLayout = (DrawerLayout)
findViewById(R.id.drawerLayout);
ActionBar supportActionBar = getSupportActionBar();
if(supportActionBar != null) {
supportActionBar.setDisplayHomeAsUpEnabled(true);
supportActionBar.setHomeButtonEnabled(true);
}
setSupportActionBar(toolbar);
final ListView drawerList = (ListView)
findViewById(R.id.drawerList);
drawerList.setAdapter(new ArrayAdapter<>(this, android.R.layout.simple_list_item_1,
new String[] { "Item 1", "Item 2", "Item 3" } ));
drawerLayout.setScrimColor(Color.TRANSPARENT);
ActionBarDrawerToggle actionBarDrawerToggle =
new ActionBarDrawerToggle(this, drawerLayout,
toolbar, R.string.app_name, R.string.app_name);
actionBarDrawerToggle.setToolbarNavigationClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(drawerLayout.isDrawerOpen(drawerList)) {
drawerLayout.closeDrawers();
} else {
drawerLayout.openDrawer(drawerList);
}
}
});
drawerLayout.addDrawerListener(actionBarDrawerToggle);
actionBarDrawerToggle.syncState();
}
