Android抽屉(SlidingDrawer)的实现

mainActivity如下:

package c.c;
import android.app.Activity;
import android.os.Bundle;
import android.widget.SlidingDrawer;
import android.widget.SlidingDrawer.OnDrawerCloseListener;
import android.widget.SlidingDrawer.OnDrawerOpenListener;
import android.widget.SlidingDrawer.OnDrawerScrollListener;
/**
 * 需求描述:
 * 实现一个很简单的抽屉Demo
 * 注意的问题:
 * 1 打开抽屉的图标,打开后的界面都是布局在<SlidingDrawer/>中
 * 2 在<SlidingDrawer/>中
 *   使用:android:handle="@+id/handle_layout"
 *   指定抽屉的把手
 *   使用:android:content="@+id/content_layout"
 *   指定打开抽屉后的View
 * 3 SlidingDrawer一共有三个监听事件(见代码)
 *   注意三者的执行顺序,总的原则是:
 *   滑动完成后,打开(或者关闭)抽屉
 *   所以:执行的顺序
 *   //1 setOnDrawerScrollListener
 *   //2 setOnDrawerOpenListener
 *       或setOnDrawerCloseListener
 */
public class MainActivity extends Activity {
    private SlidingDrawer mSlidingDrawer;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        init();
    }
    //执行的顺序
    //1 setOnDrawerScrollListener
    //2 setOnDrawerOpenListener(或者setOnDrawerCloseListener)
    private void init(){
    	mSlidingDrawer=(SlidingDrawer) findViewById(R.id.slidingDrawer);
    	mSlidingDrawer.setOnDrawerScrollListener(new OnDrawerScrollListener() {
			public void onScrollStarted() {
			    System.out.println("-------->  开始滑动");
			}
			public void onScrollEnded() {
				 System.out.println("-------->  滑动结束");
			}
		});
    	mSlidingDrawer.setOnDrawerOpenListener(new OnDrawerOpenListener() {
			public void onDrawerOpened() {
               System.out.println("-------->  打开抽屉");
			}
		});
    	mSlidingDrawer.setOnDrawerCloseListener(new OnDrawerCloseListener() {
			public void onDrawerClosed() {
				 System.out.println("-------->  关闭抽屉");
			}
		});
    }
}

main.xml如下:
