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;@Overrideprotected 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) {@Overridepublic void onDrawerOpened(View drawerView) {super.onDrawerOpened(drawerView);getActionBar().setTitle(R.string.please);}@Overridepublic 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);}@Overridepublic 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;}@Overridepublic 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);}@Overridepublic 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()... */@Overrideprotected void onPostCreate(Bundle savedInstanceState) {super.onPostCreate(savedInstanceState);// Sync the toggle state after onRestoreInstanceState has occurred.mDrawerToggle.syncState();}@Overridepublic void onConfigurationChanged(Configuration newConfig) {super.onConfigurationChanged(newConfig);// Pass any configuration change to the drawer togglsmDrawerToggle.onConfigurationChanged(newConfig);}}

代码里边有注解，就不一一解释了。

@Overridepublic 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()... */@Overrideprotected void onPostCreate(Bundle savedInstanceState) {super.onPostCreate(savedInstanceState);// Sync the toggle state after onRestoreInstanceState has occurred.mDrawerToggle.syncState();}@Overridepublic void onConfigurationChanged(Configuration newConfig) {super.onConfigurationChanged(newConfig);// Pass any configuration change to the drawer togglsmDrawerToggle.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) {@Overridepublic void onDrawerOpened(View drawerView) {super.onDrawerOpened(drawerView);getActionBar().setTitle(R.string.please);}@Overridepublic 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。
