Android 学习之Drawerlayout写侧滑菜单

我们经常利用SlidingMenu来实现侧滑菜单，谷歌推出的DrawerLayout也可以实现侧滑菜单，完全可以替代SlidingMenu，如下图所示都是用SlidingMenu开发的实例。

1、项目结构

JAVA文件中首先是一个主界面的Activity-——MainActivity,然后是一个继承与Fragment的类——ContentFragment，

布局文件中，activity_main对应于主布局文件，fragment_content对应于Fragment的布局。

2、MainActivity.java

import java.util.ArrayList;import android.net.Uri;import android.os.Bundle;import android.R.anim;import android.app.Activity;import android.app.Fragment;import android.app.FragmentManager;import android.content.Intent;import android.content.res.Configuration;import android.support.v4.app.ActionBarDrawerToggle;import android.support.v4.widget.DrawerLayout;import android.view.Menu;import android.view.MenuItem;import android.view.View;import android.widget.AdapterView;import android.widget.AdapterView.OnItemClickListener;import android.widget.ArrayAdapter;import android.widget.ImageView;import android.widget.LinearLayout;import android.widget.ListView;public class MainActivity extends Activity implements OnItemClickListener {	private DrawerLayout mDrawerLayout;	private ListView mDrawerList;	private LinearLayout mlayout;	private ArrayList
      
        menuLists;	private ArrayAdapter
       
         adapter;	private ActionBarDrawerToggle mDrawerToggle;	private String mTitle;    private ImageView imageView;	@Override	protected void onCreate(Bundle savedInstanceState) {		super.onCreate(savedInstanceState);		setContentView(R.layout.activity_main);		mTitle = (String) getTitle();		imageView = (ImageView) findViewById(R.id.image);		mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);		mDrawerList = (ListView) findViewById(R.id.left_drawer);		mlayout = (LinearLayout) findViewById(R.id.mlayout);		menuLists = new ArrayList
        
         ();		for (int i = 0; i < 5; i++)			menuLists.add("菜单0" + i);		adapter = new ArrayAdapter
         
          (this,				android.R.layout.simple_list_item_1, menuLists);		mDrawerList.setAdapter(adapter);		mDrawerList.setOnItemClickListener(this);		mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,				R.drawable.ic_drawer, R.string.drawer_open,				R.string.drawer_close) {			@Override			public void onDrawerOpened(View drawerView) {				super.onDrawerOpened(drawerView);				getActionBar().setTitle("请选择");				invalidateOptionsMenu(); // Call onPrepareOptionsMenu()			}			@Override			public void onDrawerClosed(View drawerView) {				super.onDrawerClosed(drawerView);				getActionBar().setTitle(mTitle);				invalidateOptionsMenu();			}		};		mDrawerLayout.setDrawerListener(mDrawerToggle);		//开启ActionBar的App Icon功能		getActionBar().setDisplayHomeAsUpEnabled(true);		getActionBar().setHomeButtonEnabled(true);	}	@Override	public boolean onPrepareOptionsMenu(Menu menu) {		boolean isDrawerOpen = mDrawerLayout.isDrawerOpen(mlayout);		menu.findItem(R.id.action_websearch).setVisible(!isDrawerOpen);		return super.onPrepareOptionsMenu(menu);	}	@Override	public boolean onCreateOptionsMenu(Menu menu) {		// Inflate the menu; this adds items to the action bar if it is present.		getMenuInflater().inflate(R.menu.main, menu);		return true;	}	@Override	public boolean onOptionsItemSelected(MenuItem item) {		//将ActionBar上的图标与Drawer结合起来		if (mDrawerToggle.onOptionsItemSelected(item)){			return true;		}		switch (item.getItemId()) {		case R.id.action_websearch:			Intent intent = new Intent();			intent.setAction("android.intent.action.VIEW");			Uri uri = Uri.parse("http://www.csdn.net");			intent.setData(uri);			startActivity(intent);			break;		}		return super.onOptionsItemSelected(item);	}		@Override	protected void onPostCreate(Bundle savedInstanceState) {		super.onPostCreate(savedInstanceState);		//需要将ActionDrawerToggle与DrawerLayout的状态同步		//将ActionBarDrawerToggle中的drawer图标，设置为ActionBar中的Home-Button的Icon		mDrawerToggle.syncState();	}		@Override	public void onConfigurationChanged(Configuration newConfig) {		super.onConfigurationChanged(newConfig);		mDrawerToggle.onConfigurationChanged(newConfig);	}	@Override	public void onItemClick(AdapterView
           arg0, View arg1, int position,			long arg3) {		// 在FrameLayout中动态插入一个Fragment		Fragment contentFragment = new ContentFragment();		Bundle args = new Bundle();		args.putString("text", menuLists.get(position));		contentFragment.setArguments(args);		FragmentManager fm = getFragmentManager();		fm.beginTransaction().replace(R.id.content_frame, contentFragment)				.commit();		mDrawerLayout.closeDrawer(mlayout);	}}

3、ContentFragment.java

import android.app.Fragment;import android.os.Bundle;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.TextView;public class ContentFragment extends Fragment {		private TextView textView;		@Override	public View onCreateView(LayoutInflater inflater, ViewGroup container,			Bundle savedInstanceState) {		View view = inflater.inflate(R.layout.fragment_content, container, false);		textView = (TextView) view.findViewById(R.id.textView);				String text = getArguments().getString("text");		textView.setText(text);				return view;	}	}

4、activity_main.xml

5、fragment_content.xml

6、menu（main.xml)

7、效果图
