Andorid DrawerLayout控件的使用方法

一、概述：

1、效果图：

2、使用DrawerLayout可以轻松实现slidingmenu的功能，并且简单易用

二、具体实现：

1、创建布局文件，以DrawerLayout作为包裹layout，里面添加viewpager和一个FrameLayout
其中viewpager用来实现右侧的内容，而fragment用来添加左侧的菜单

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/drawerlayout_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <android.support.v4.view.ViewPager
        android:id="@+id/vp_main"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true" >

        <android.support.v4.view.PagerTabStrip
            android:id="@+id/pager_tab_strip"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="top"
            android:background="#d17026"
            android:textColor="#fff" />
    </android.support.v4.view.ViewPager>

    <FrameLayout
        android:id="@+id/fl_menu"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="start"
        android:text="应用详情" >
    </FrameLayout>

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

2、创建BaseActivity，继承ActionBarActivity

/**
 * @描述 基础activity
 * @项目名称 App_Shop
 * @包名 com.android.shop
 * @类名 BaseActivity
 * @author chenlin
 * @date 2013-3-25 下午10:47:47
 * @version 1.0
 */

public abstract class BaseActivity extends ActionBarActivity {
    //public final static  String KILLACTION= "com.android.killreceiver";
    public static BaseActivity activity;

    private List<BaseActivity> mActivities = new LinkedList<BaseActivity>();
    private KillReceiver mReceiver;

    private class KillReceiver extends BroadcastReceiver{
        @Override
        public void onReceive(Context context, Intent intent) {
            finish();
        }
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //mReceiver = new KillReceiver();
        //registerReceiver(mReceiver, new IntentFilter(KILLACTION));
        synchronized (mActivities) {
            mActivities.add(this);
        }

        init();
        initViews();
        initActionBar();
        initEvents();
    }

    //---onPause --onResume  用来判断activity是否存在--------在util.startActivity里使用--------------------------------

    @Override
    protected void onPause() {
        activity = null;
        super.onPause();
    }

    @Override
    protected void onResume() {
        activity = this;
        super.onResume();
    }

    /**
     * 关闭所有的activity
     */
    public void finishAll() {
        List<BaseActivity> copyActivities = null;
        synchronized (mActivities) {
            copyActivities = new LinkedList<BaseActivity>(mActivities);
        }
        if (copyActivities != null && copyActivities.size() > 0) {
            for (BaseActivity activity : copyActivities) {
                activity.finish();
            }
            android.os.Process.killProcess(android.os.Process.myPid());
        }
    }

    public abstract void init();
    public abstract void initViews();


    protected void initEvents() {

    }

    protected void initActionBar() {
    }

    public void toast(String text){
        Toast.makeText(getApplicationContext(), text, Toast.LENGTH_LONG).show();
    }

    public void alert(final String text){
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                Toast.makeText(getApplicationContext(), text, Toast.LENGTH_LONG).show();
            }
        });

    }



    @Override
    protected void onDestroy() {
        synchronized (mActivities) {
            mActivities.remove(this);
        }

        if (mReceiver != null) {
            unregisterReceiver(mReceiver);
            mReceiver = null;
        }

        super.onDestroy();
    }
}

3、创建MainActivity继承BaseActivity
这里得定义ActionBarDrawerToggle , DrawerLayout的侧拉事件都是由其实现的

package com.android.shop;

import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.Intent;
import android.support.v4.app.ActionBarDrawerToggle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentStatePagerAdapter;
import android.support.v4.view.PagerTabStrip;
import android.support.v4.view.ViewPager;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBar;
import android.support.v7.widget.SearchView;
import android.support.v7.widget.SearchView.OnQueryTextListener;
import android.view.KeyEvent;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.widget.FrameLayout;
import android.widget.Toast;

import com.android.shop.adapter.holder.MenuHolder;
import com.android.shop.helper.FragmentFactory;
import com.android.shop.utils.Util;

public class MainActivity extends BaseActivity implements OnQueryTextListener {
    private DrawerLayout mDrawerLayout;
    private ActionBarDrawerToggle mDrawerToggle;
    private ViewPager mViewPager;
    private PagerTabStrip mTabStrip;
    private String[] mTabNames;
    private Fragment mCurrentFragment;
    private FrameLayout mMenuFragment;

    @Override
    public void init() {
        //sendBroadcast(new Intent(KILLACTION)); 关闭activity
        setContentView(R.layout.activity_main);
        mTabNames = Util.getStringArray(R.array.tab_names);
    }

    @Override
    public void initViews() {
        mViewPager = (ViewPager) findViewById(R.id.vp_main);
        mViewPager.setAdapter(new TabPagerAdapter(getSupportFragmentManager()));

        mTabStrip = (PagerTabStrip) findViewById(R.id.pager_tab_strip);
        mTabStrip.setTabIndicatorColor(getResources().getColor(R.color.tabIndicator_color));

        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerlayout_main);

        //加载左侧的菜单信息
        mMenuFragment = (FrameLayout) findViewById(R.id.fl_menu);
        MenuHolder holder  = new MenuHolder();
        mMenuFragment.addView(holder.getConvertView());
    }

    @Override
    protected void initEvents() {
        mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener(){
            @Override
            public void onPageSelected(int position) {
                //getSupportActionBar().setSelectedNavigationItem(position);
                //在页面切换时显示不同的加载页面
                FragmentFactory.createFragment(position).show();
                super.onPageSelected(position);
            }
        });
    }

    @Override
    protected void initActionBar() {
        //getSupportActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
        //添加菜单
        ActionBar actionBar = getSupportActionBar();
        actionBar.setDisplayHomeAsUpEnabled(true);
        actionBar.setHomeButtonEnabled(true);

        mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.ic_drawer, R.string.open_drawer, R.string.close_drawer){
            @Override
            public void onDrawerClosed(View drawerView) {
                super.onDrawerClosed(drawerView);
            }
            @Override
            public void onDrawerOpened(View drawerView) {
            }
        };
        mDrawerLayout.setDrawerListener(mDrawerToggle);
        mDrawerToggle.syncState();
    }

    public void toDetail(View view) {
        Intent intent = new Intent(this, DetailActivity.class);
        startActivity(intent);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.activity_main, menu);
        //if (android.os.Build.VERSION.SDK_INT >= 11) {
            SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
            //设置查询监听
            searchView.setOnQueryTextListener(this);
        //}
        return super.onCreateOptionsMenu(menu);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (item.getItemId() == R.id.action_search) {
            Toast.makeText(this, "搜索", Toast.LENGTH_LONG).show();
        }
        return super.onOptionsItemSelected(item) | mDrawerToggle.onOptionsItemSelected(item);
    }

    @Override
    public boolean onQueryTextSubmit(String query) {
        // TODO Auto-generated method stub
        return true;// true表示执行此方法
    }

    @Override
    public boolean onQueryTextChange(String newText) {
        // TODO Auto-generated method stub
        return true;
    }


    private class TabPagerAdapter extends FragmentStatePagerAdapter{

        public TabPagerAdapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        public Fragment getItem(int position) {
            mCurrentFragment = FragmentFactory.createFragment(position);
            return mCurrentFragment;
        }

        @Override
        public int getCount() {
            return mTabNames.length;
        }

        @Override
        public CharSequence getPageTitle(int position) {
            return mTabNames[position];
        }

    }


    @Override
     public boolean dispatchKeyEvent(KeyEvent event) {
       if (event.getAction()==KeyEvent.ACTION_DOWN&&event.getKeyCode()==KeyEvent.KEYCODE_BACK) {
        new AlertDialog.Builder(this)
               .setCancelable(false)
               .setTitle("温馨提示")
               .setMessage("您确定要退出吗?")
               .setPositiveButton("确定",new DialogInterface.OnClickListener() {
                   public void onClick(DialogInterface dialog, int which) { 
                      finishAll();
                   }
               })
               .setNegativeButton("取消", new DialogInterface.OnClickListener() {
                   public void onClick(DialogInterface dialog, int which) { 

                   }
               }).show();
        return true;
      }

      return super.dispatchKeyEvent(event);

     }

}
