android中的v4包下面给我们提供了一个可以实现抽屉效果的控件DrawerLayout。让我们一起去了解一下这个DrawerLayout。废话不多说了，直接贴代码.。

代码如下：

package com.example.drawerlayout;

import java.util.ArrayList;

import android.os.Bundle;
import android.app.ActionBar;
import android.app.Activity;
import android.content.Context;
import android.content.res.Configuration;
import android.support.v4.app.ActionBarDrawerToggle;
import android.support.v4.widget.DrawerLayout;
import android.support.v4.widget.DrawerLayout.DrawerListener;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.SlidingDrawer.OnDrawerOpenListener;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity {
	private String string[] = new String[12];
	private ArrayList<String> list = new ArrayList<String>();
	private ActionBarDrawerToggle toggle;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		
		
		DrawerLayout layout = (DrawerLayout) findViewById(R.id.drawer);
		ImageView imageView = (ImageView) findViewById(R.id.img);
		final ListView listView = (ListView) findViewById(R.id.list);
		
		
		//获取手机的菜单栏
		final ActionBar actionBar = getActionBar();
		actionBar.setTitle("主界面");
		//标题栏的home可以点击
		actionBar.setIcon(android.R.drawable.btn_radio);
		actionBar.setDisplayHomeAsUpEnabled(true);
		actionBar.setHomeButtonEnabled(true);
		
		
		toggle = new ActionBarDrawerToggle(MainActivity.this,
				layout, android.R.drawable.btn_star, 
				android.R.drawable.btn_star_big_on, 
				android.R.drawable.btn_star_big_off){
			@Override
			public void onDrawerClosed(View drawerView) {
				super.onDrawerClosed(drawerView);
				actionBar.setTitle("主界面");
			}
			@Override
					public void onDrawerOpened(View drawerView) {
						super.onDrawerOpened(drawerView);
						actionBar.setTitle("菜单界面");
					}
			
		};
		//打开或者关闭时的状态
		toggle.syncState();
		layout.setDrawerListener(toggle);
		
		
		

		for (int i = 0; i < string.length; i++) {
			list.add("想发火" + i);
		}
		
		
		if (list != null && list.size() > 0) {
			MyAdapter adapter = new MyAdapter(MainActivity.this, list);

			listView.setAdapter(adapter);
		}

		listView.setOnItemClickListener(new OnItemClickListener() {

			@Override
			public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
					long arg3) {
				Toast.makeText(MainActivity.this, "我想打死你,***",
						Toast.LENGTH_SHORT).show();
			}
		});
	}
	
	@Override
	public boolean onOptionsItemSelected(MenuItem item) {
		return toggle.onOptionsItemSelected(item)||super.onOptionsItemSelected(item);
	}
	@Override
	public void onConfigurationChanged(Configuration newConfig) {
		super.onConfigurationChanged(newConfig);
		toggle.onConfigurationChanged(newConfig);
	}

}



class MyAdapter extends BaseAdapter {
	private Context context;
	private ArrayList<String> list;

	public MyAdapter(Context context, ArrayList<String> list) {
		this.context = context;
		this.list = list;
	}

	@Override
	public int getCount() {
		return list.size();
	}

	@Override
	public Object getItem(int arg0) {
		return null;
	}

	@Override
	public long getItemId(int arg0) {
		return arg0;
	}

	@Override
	public View getView(int arg0, View arg1, ViewGroup arg2) {
		ViewHolder vHolder;
		if (arg1 == null) {
			arg1 = LayoutInflater.from(context).inflate(R.layout.listview_item,
					null);
			vHolder = new ViewHolder();
			vHolder.textView = (TextView) arg1.findViewById(R.id.list_text);
			arg1.setTag(vHolder);
		} else {
			vHolder = (ViewHolder) arg1.getTag();
		}
		String string = list.get(arg0);
		vHolder.textView.setText(string);
		return arg1;
	}

	class ViewHolder {
		TextView textView;
	}

}

这个是mainactivity中的代码，为了简洁，直接将适配器以内部类的形式给出。但是这种写法按常规是不合理的，代码也不整洁，看着比较乱。不推荐使用此写法。

下面给出相关的布局文件：

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent" >

        <ImageView
            android:id="@+id/img"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_launcher" />
    </LinearLayout>

    <LinearLayout
        android:layout_width="300dp"
        android:layout_height="match_parent"
        android:layout_gravity="left"
        android:background="#ff0" >

        <ListView
            android:id="@+id/list"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </LinearLayout>

</android.support.v4.widget.DrawerLayout>

<RelativeLayout 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"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" 
    android:background="#ddf">

    <include layout="@layout/drawer_item" />

</RelativeLayout>

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <TextView
        android:id="@+id/list_text"
        android:layout_width="match_parent"
        android:layout_height="match_parent" 
        />

</RelativeLayout>

从上面的布局代码可以看出，采用了布局优化之include的写法。（还有一种常用的布局优化方式是样式抽取）。

效果如下：

这个就是使用DrawerLayout实现抽屉效果的代码，比较重要的地方给出了注释，如有不理解的地方，欢迎提出问题，博主会在第一时间给您解答。

不足之处还望多多指教！
