google 原生态 抽屉式侧滑菜单 Android DrawerLayout 布局的使用介绍

废话不多说，直接上效果图：

其实谷歌官方已经给出了一个 关于DrawerLayout 使用的例子，只是处于 国内不能访问谷歌官网，看不到详细文档说明，所以在此 简单记录下  侧滑 抽屉式菜单的使用说明

1.由于 DrawerLayout 需要 android.support.v4 包的支持，所以，你的libs 下面不要包含 这个包。

2.首先布局文件如下

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

    <!-- the main content view -->

    <FrameLayout
        android:id="@+id/frame_content"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
    </FrameLayout>

    <!-- the navigetion view -->

    <ListView
        android:id="@+id/drawer_list"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="#9999cc"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp" >
    </ListView>

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

注意：1.布局中的ListView 就是就是侧滑菜单 布局容器，其中 android:layout_gravity 属性必须赋值。 目的是侧滑菜单的显示位置，官方推荐使用“start”-----左侧  "end"----右侧

不推荐使用 “left”---左侧，“right”---右侧。

2.FrameLayout 显示主内容部分。

其实到了这一步就已经实现了侧滑菜单效果了，可以运行试试，只是现在的侧滑菜单里面没有任何元素。

3.代码编写如下：

package com.example.drawlayout1;

import android.os.Bundle;
import android.app.Activity;
import android.app.Fragment;
import android.app.FragmentManager;
import android.content.res.Configuration;
import android.support.v4.app.ActionBarDrawerToggle;
import android.support.v4.view.GravityCompat;
import android.support.v4.widget.DrawerLayout;
import android.view.LayoutInflater;
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.ListView;

public class MainActivity extends Activity implements OnItemClickListener {

	private DrawerLayout mDrawerLayout;
	private ListView mDrawerList;
	private String[] menuLists;
	private ArrayAdapter<String> adapter;
	private ActionBarDrawerToggle mDrawerToggle;
	private String titleString;
	private int iSelect = -1;
	private View heandrView;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		/*get the application title*/
		titleString = (String) getTitle();

		heandrView = LayoutInflater.from(this).inflate(R.layout.home_menu_list_header, null);

		mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
		mDrawerList = (ListView) findViewById(R.id.drawer_list);
		mDrawerList.addHeaderView(heandrView);
		menuLists = getResources().getStringArray(R.array.menu_content);

		adapter = new ArrayAdapter<String>(this,
				android.R.layout.simple_list_item_1, menuLists);
		mDrawerList.setAdapter(adapter);
		mDrawerList.setOnItemClickListener(this);

		/*set the shadow for drawer at start(left) or end(right)*/
		mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow,
				GravityCompat.START);

		/*show the home icon*/
		getActionBar().setDisplayHomeAsUpEnabled(true);
		/*make sure the home icon enable click*/
		getActionBar().setHomeButtonEnabled(true);

		/*set the application ActionBar title changes*/
		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(R.string.please);
			}

			@Override
			public void onDrawerClosed(View drawerView) {
				super.onDrawerClosed(drawerView);
				if (-1 == iSelect) {
					getActionBar().setTitle(titleString);
				} else {
					getActionBar().setTitle(menuLists[iSelect-1]);
				}
			}
		};
		/*set the DrawerLayout Listener*/
		mDrawerLayout.setDrawerListener(mDrawerToggle);
	}

	@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) {
		/*make sure the home icon enable click and display the DrawerLayout*/
		if (mDrawerToggle.onOptionsItemSelected(item)){
			return true;
		}
		return super.onOptionsItemSelected(item);
	}

	@Override
	public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
		Fragment contentFragment = new ContentFragment();
		Bundle args = new Bundle();
		iSelect = arg2;
		if (0 == iSelect){
			iSelect = 1;
		}
		args.putString("text", menuLists[iSelect-1]);
		contentFragment.setArguments(args);

		FragmentManager fm = getFragmentManager();
		fm.beginTransaction().replace(R.id.frame_content, contentFragment)
				.commit();
		mDrawerLayout.closeDrawer(mDrawerList);
	}

	/**
	 * When using the ActionBarDrawerToggle, you must call it during
	 * onPostCreate() and onConfigurationChanged()...
	 */
	@Override
	protected void onPostCreate(Bundle savedInstanceState) {
		super.onPostCreate(savedInstanceState);
		// Sync the toggle state after onRestoreInstanceState has occurred.
		mDrawerToggle.syncState();
	}

	@Override
	public void onConfigurationChanged(Configuration newConfig) {
		super.onConfigurationChanged(newConfig);
		// Pass any configuration change to the drawer toggls
		mDrawerToggle.onConfigurationChanged(newConfig);
	}

}

代码里边有注解，就不一一解释了。

@Override
	public boolean onOptionsItemSelected(MenuItem item) {
		/*make sure the home icon enable click and display the DrawerLayout*/
		if (mDrawerToggle.onOptionsItemSelected(item)){
			return true;
		}
		return super.onOptionsItemSelected(item);
	}

这段代码的目的：点击ActionBar导航栏上的Home 按键弹出和关闭 DrawerLayout 侧滑菜单。

/**
	 * When using the ActionBarDrawerToggle, you must call it during
	 * onPostCreate() and onConfigurationChanged()...
	 */
	@Override
	protected void onPostCreate(Bundle savedInstanceState) {
		super.onPostCreate(savedInstanceState);
		// Sync the toggle state after onRestoreInstanceState has occurred.
		mDrawerToggle.syncState();
	}

	@Override
	public void onConfigurationChanged(Configuration newConfig) {
		super.onConfigurationChanged(newConfig);
		// Pass any configuration change to the drawer toggls
		mDrawerToggle.onConfigurationChanged(newConfig);
	}

这段代码的目的：谷歌官方极力推荐重写两个方法，第一个方法 实现ActionBar 的Home键和 DrawerLayout 抽屉菜单关联，并且ActionBar的Home 有动画效果。

第二个方法 是在横屏的时候调用。保存状态。

mDrawerList.setOnItemClickListener(this);

这段代码是添加DrawerLayout 抽屉菜单 里面元素的点击事件，代码中实现点击不同元素，替换不同FragMent。

/*set the application ActionBar title changes*/
		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(R.string.please);
			}

			@Override
			public void onDrawerClosed(View drawerView) {
				super.onDrawerClosed(drawerView);
				if (-1 == iSelect) {
					getActionBar().setTitle(titleString);
				} else {
					getActionBar().setTitle(menuLists[iSelect-1]);
				}
			}
		};
		/*set the DrawerLayout Listener*/
		mDrawerLayout.setDrawerListener(mDrawerToggle);

这段代码是 添加侧滑 菜单 DrawerLayout 的打开关闭监听事件，在打开关闭方法中重写 自己需要实现的效果。
