Android-----DrawerLayout的使用

1, 谷歌建議跟佈局使用DrawerLayout, DrawerLayout是V4包裏的控件;

2  給DrawerLayout中的控件設置一下兩種屬性,屬性設置給誰,側拉出來的就是誰;可以設置給圖片, 按鈕 ListView等等;

	android:layout_gravity="left"
	android:choiceMode="singleChoice"

    <!--
    和drawerLayout配合需要配這兩個屬性
    android:layout_gravity="left"
        android:choiceMode="singleChoice"
        -->
    <ListView
