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。
