1.安装最火、最快的Android模拟器：genymotion模拟器

2.安装服务器WebServer(里面是假数据)

3.在sd卡的根目录下放置WebInfos文件夹

活动条(ActionBar)是Android3.0的重要更新之一。ActionBar位于传统标题栏的位置，也就是显示的屏幕的顶部。ActionBar可显示应用的图标和Activity标题——也就是前面应用程序的顶部显示的内容。除此之外，ActionBar的右边还可以显示活动项(Action Item)。

• Action Bar设计概念在Android3.0(APP 11)中被Google引入以后，在4.0版本之后更是被Google纳入设计规范中，从Google的各大App中都可以看到这种设计。
• 兼容低版本
  • 引入android-support-v7-appcompat
  • ActionBarCompat在使用中会调用一些资源文件，尤其是基于Theme.Appcompat的主题（Theme）用来规范Action Bar的显示。如果使用Action Bar的Activity没有使用基于Theme.Appcompat的主题，程序就不知道该如何配制Action Bar的显示，就会报错导致程序退出。
  • 继承ActionBarActivity

步骤：

1.引用v7-appcompat

2.Activity继承ActionBarActivity

3.android:theme="@/style/Theme.AppCompat.Lighr"

代码实现：

MainActivity.java

package com.xbmu.google;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Menu;
public class MainActivity extends ActionBarActivity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {getMenuInflater().inflate(R.menu.main, menu);return true;}
}

在项目清单文件(AndroidManifest.xm)中的Application标签里修改：

<applicationandroid:allowBackup="true"android:icon="@drawable/ic_launcher"android:label="@string/app_name"android:theme="@style/Theme.AppCompat.Light" ><activityandroid:name="com.xbmu.google.MainActivity"android:label="@string/app_name" ><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter></activity></application>

运行效果：

学习参考Api Demos中的代码：

首先看一下Api Demos中Action Bar的搜素的案例：

将Api Demos的工程导入开发工具中，找到代码：

在我们项目中实现搜素功能：

参考Android开发文档：http://wear.techbrood.com/

res/menu/main_activity_actions.xml

MainActivity.java

package com.xbmu.google;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.widget.SearchView;
import android.support.v7.widget.SearchView.OnQueryTextListener;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.widget.Toast;
public class MainActivity extends ActionBarActivity implements OnQueryTextListener {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {MenuInflater inflater = getMenuInflater();inflater.inflate(R.menu.main_activity_actions, menu);SearchView searchView  = (SearchView) menu.findItem(R.id.action_search).getActionView();searchView.setOnQueryTextListener(this);//设置搜素的监听事件return true;}/**处理actionBar菜单条目的点击事件*/@Overridepublic boolean onOptionsItemSelected(MenuItem item) {if(item.getItemId() == R.id.action_search){Toast.makeText(getApplicationContext(), "搜素", 0).show();}return super.onOptionsItemSelected(item);}//当搜素文本发生变化的时候@Overridepublic boolean onQueryTextChange(String newText) {Toast.makeText(getApplicationContext(), newText, 0).show();return false;}//当搜素提交的时候@Overridepublic boolean onQueryTextSubmit(String query) {Toast.makeText(getApplicationContext(), query, 0).show();return false;}
}

运行效果：

详情页面DetailActivity.java

package com.xbmu.google;import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
public class DetailActivity extends ActionBarActivity {@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);setContentView(R.layout.activity_detail);}
}

activity_detail.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical" ><Button android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="详情页面"android:layout_centerInParent="true"/>
</RelativeLayout>

在清单文件中声明：

 <activityandroid:name="com.xbmu.google.DetailActivity"android:label="@string/app_detail"android:parentActivityName="com.xbmu.google.MainActivity" ><!-- Parent activity meta-data to support 4.0 and lower --><meta-dataandroid:name="android.support.PARENT_ACTIVITY"android:value="com.xbmu.google.MainActivity" /></activity>

MainActivity.java:

package com.xbmu.google;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.ActionBar;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.widget.SearchView;
import android.support.v7.widget.SearchView.OnQueryTextListener;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.widget.Toast;
public class MainActivity extends ActionBarActivity implements OnQueryTextListener {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);ActionBar actionBar = getSupportActionBar();//设置是否将应用程序图标转变成可点击的图标，并在图标上添加一个向左的箭头。actionBar.setDisplayHomeAsUpEnabled(true);}public void jump(View view){Intent intent = new Intent(this, DetailActivity.class);startActivity(intent);}//......
}

activity_main.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent" ><Button android:layout_width="match_parent"android:layout_height="wrap_content"android:text="跳转到详情页面"android:onClick="jump"/>
</RelativeLayout>

运行效果图：

1.在Drawable目录下写一个标签的状态选择器

res/drawable/actionbar_tab_indicator.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android"><!-- STATES WHEN BUTTON IS NOT PRESSED --><!-- Non focused states --><item android:state_focused="false" android:state_selected="false"android:state_pressed="false"android:drawable="@drawable/tab_unselected" /><item android:state_focused="false" android:state_selected="true"android:state_pressed="false"android:drawable="@drawable/tab_selected" /><!-- Focused states (such as when focused with a d-pad or mouse hover) --><item android:state_focused="true" android:state_selected="false"android:state_pressed="false"android:drawable="@drawable/tab_unselected_focused" /><item android:state_focused="true" android:state_selected="true"android:state_pressed="false"android:drawable="@drawable/tab_selected_focused" /><!-- STATES WHEN BUTTON IS PRESSED --><!-- Non focused states --><item android:state_focused="false" android:state_selected="false"android:state_pressed="true"android:drawable="@drawable/tab_unselected_pressed" /><item android:state_focused="false" android:state_selected="true"android:state_pressed="true"android:drawable="@drawable/tab_selected_pressed" /><!-- Focused states (such as when focused with a d-pad or mouse hover) --><item android:state_focused="true" android:state_selected="false"android:state_pressed="true"android:drawable="@drawable/tab_unselected_pressed" /><item android:state_focused="true" android:state_selected="true"android:state_pressed="true"android:drawable="@drawable/tab_selected_pressed" />
</selector>

2.实现自定义主题：

res/values/themes.xml

<?xml version="1.0" encoding="utf-8"?>
<resources><!-- the theme applied to the application or activity --><style name="CustomActionBarTheme"parent="@style/Theme.AppCompat.Light"><item name="android:actionBarTabStyle">@style/MyActionBarTabs</item></style><!-- ActionBar tabs styles --><style name="MyActionBarTabs"parent="@style/Widget.AppCompat.ActionBar.TabView"><!-- tab indicator --><item name="android:background">@drawable/actionbar_tab_indicator</item></style>
</resources>

3.在MainActivity.java中添加标签代码：

package com.xbmu.google;
import android.annotation.SuppressLint;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.FragmentTransaction;
import android.support.v7.app.ActionBar;
import android.support.v7.app.ActionBar.Tab;
import android.support.v7.app.ActionBar.TabListener;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.widget.SearchView;
import android.support.v7.widget.SearchView.OnQueryTextListener;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.widget.Toast;
public class MainActivity extends ActionBarActivity implements OnQueryTextListener {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);ActionBar actionBar = getSupportActionBar();//设置是否将应用程序图标转变成可点击的图标，并在图标上添加一个向左的箭头。actionBar.setDisplayHomeAsUpEnabled(true);actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);Tab tab1 = actionBar.newTab().setText("标签一").setTabListener(new MyTabListener());actionBar.addTab(tab1);Tab tab2 = actionBar.newTab().setText("标签二").setTabListener(new MyTabListener());actionBar.addTab(tab2);Tab tab3 = actionBar.newTab().setText("标签三").setTabListener(new MyTabListener());actionBar.addTab(tab3);Tab tab4 = actionBar.newTab().setText("标签四").setTabListener(new MyTabListener());actionBar.addTab(tab4);Tab tab5 = actionBar.newTab().setText("标签五").setTabListener(new MyTabListener());actionBar.addTab(tab5);}private class MyTabListener implements TabListener{@Overridepublic void onTabReselected(Tab arg0, FragmentTransaction arg1) {// TODO Auto-generated method stub}@Overridepublic void onTabSelected(Tab arg0, FragmentTransaction arg1) {// TODO Auto-generated method stub}@Overridepublic void onTabUnselected(Tab arg0, FragmentTransaction arg1) {// TODO Auto-generated method stub}}public void jump(View view){Intent intent = new Intent(this, DetailActivity.class);startActivity(intent);}@SuppressLint("NewApi")@Overridepublic boolean onCreateOptionsMenu(Menu menu) {MenuInflater inflater = getMenuInflater();inflater.inflate(R.menu.main_activity_actions, menu);//如果运行的环境(部署到什么版本的手机)大于3.0if(android.os.Build.VERSION.SDK_INT > 11){SearchView searchView  = (SearchView) menu.findItem(R.id.action_search).getActionView();searchView.setOnQueryTextListener(this);//设置搜素的监听事件           }return true;}/**处理actionBar菜单条目的点击事件*/@Overridepublic boolean onOptionsItemSelected(MenuItem item) {if(item.getItemId() == R.id.action_search){Toast.makeText(getApplicationContext(), "搜素", 0).show();}return super.onOptionsItemSelected(item);}//当搜素文本发生变化的时候@Overridepublic boolean onQueryTextChange(String newText) {Toast.makeText(getApplicationContext(), newText, 0).show();return false;}//当搜素提交的时候@Overridepublic boolean onQueryTextSubmit(String query) {Toast.makeText(getApplicationContext(), query, 0).show();return false;}
}

布局文件activity_main.xml

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent" android:id="@+id/dl"><LinearLayoutandroid:layout_width="match_parent"android:layout_height="match_parent"android:layout_centerHorizontal="true"android:layout_centerVertical="true" /><FrameLayoutandroid:layout_width="match_parent"android:layout_height="match_parent"android:layout_gravity="left"android:background="@drawable/bg_tab" /></android.support.v4.widget.DrawerLayout>
