關於如何生成側邊欄這件事
更改activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context="com.example.vincent.showetf.MainActivity"
android:id="@+id/drawerLayout">
<!-- center 主程式位置-->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello"
android:textSize="40sp" />
</LinearLayout>
<android.support.design.widget.NavigationView
android:id="@+id/navigation_view"
android:layout_width="240dp"
android:layout_gravity="start"
android:layout_height="match_parent"
app:menu="@menu/activity_menu" />
</android.support.v4.widget.DrawerLayout>
生成menu的資料夾
如下圖
接著生成menu的resource.file
activity_menu
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single">
<item
android:id="@+id/showProduct"
android:title="@string/showProduct"/>
<item
android:id="@+id/feedback"
android:title="@string/feedback"/>
</group>
</menu>
更改values資料夾裡的string檔
<resources>
<string name="app_name">showProduct</string>
<string name="showProduct">展示商品</string>
<string name="feedback">意見反饋</string>
</resources>
