Android编程实现抽屉效果的方法详解

<!-- 在SlidingDrawer这个标签下android:handle：指示的就是抽屉的图片。
android:content:指向的就是抽屉里面的布局。有了这个布局，其实一个抽屉就出来了 -->
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent" >
  <TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/hello"
    android:textSize="20sp" />
  <SlidingDrawer
