本实践在于练习使用ActionBarDrawerToggle+DrawerLayout实现双向侧滑栏菜单布局
需要的库文件 android-v7-appcompat
所选要的jar android-support-v4.jar,android.jar
效果图
点击Home菜单 ↓-->searchview被隐藏
点击照相机 ↓-->searchview被隐藏
点击搜索 ↓
点击隐藏菜单 ↓
首先是ActionBar的菜单设计toggle_menu.xml
<menu 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"
tools:context="com.example.actiontabbar.DrawerToggleActivity" >
<item android:id="@+id/action_search"
android:orderInCategory="100"
android:title="@string/action_search"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="ifRoom"
/>
<item
android:id="@+id/action_camera"
android:orderInCategory="100"
android:icon="@drawable/ofm_camera_icon"
android:title="@string/action_camera"
app:showAsAction="ifRoom"/>
<item
android:id="@+id/action_settings"
android:orderInCategory="100"
android:icon="@drawable/ofm_setting_icon"
android:title="@string/action_settings"
app:showAsAction="never"/>
</menu>布局文件drawertoggle_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/main_drawer_layout"
android:orientation="vertical" >
<FrameLayout
android:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
<LinearLayout
android:id="@+id/main_left_menu"
android:layout_width="200dip"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_gravity="start"
android:background="#f09001"
/>
<LinearLayout
android:id="@+id/main_right_menu"
android:layout_width="200dip"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_gravity="end"
android:background="#f09001"
/>
</android.support.v4.widget.DrawerLayout>Activity代码
