ActionBar实现Tab

1.修改主题

android:theme="@style/CustomActionBarTheme">

在values中建theme.xml样式文件

<?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>

        <!-- Support library compatibility -->
        <item name="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>

        <!-- Support library compatibility -->
        <item name="background">@drawable/actionbar_tab_indicator</item>
    </style>
</resources>

menu的写法

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:yourapp="http://schemas.android.com/apk/res-auto" >

    <!-- Search, should appear as action button -->
    <item
        android:id="@+id/action_search"
        android:icon="@drawable/ic_action_search"
        android:title="@string/action_search"
        yourapp:actionViewClass="android.support.v7.widget.SearchView"
        yourapp:showAsAction="ifRoom"/>

</menu>

代码实现

package com.itheima.googleplay;


import android.annotation.SuppressLint;
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.MenuItem;
import android.widget.Toast;

public class MainActivity extends ActionBarActivity implements
		OnQueryTextListener {
	
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		ActionBar actionBar = getSupportActionBar();
		actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
		Tab tab1 = actionBar.newTab().setText("标签一").setTabListener(new MyTabListener());
		Tab tab2 = actionBar.newTab().setText("标签2").setTabListener(new MyTabListener());
		Tab tab3 = actionBar.newTab().setText("标签3").setTabListener(new MyTabListener());
		Tab tab4 = actionBar.newTab().setText("标签4").setTabListener(new MyTabListener());
		actionBar.addTab(tab1);
		actionBar.addTab(tab2);
		actionBar.addTab(tab3);
		actionBar.addTab(tab4);
	}
	
	
	class MyTabListener implements TabListener{

		@Override
		public void onTabReselected(Tab arg0, FragmentTransaction arg1) {
			// TODO Auto-generated method stub
			
		}

		@Override
		public void onTabSelected(Tab arg0, FragmentTransaction arg1) {
			// TODO Auto-generated method stub
			
		}

		@Override
		public void onTabUnselected(Tab arg0, FragmentTransaction arg1) {
			// TODO Auto-generated method stub
			
		}
	}
	
	@SuppressLint("NewApi")
	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		getMenuInflater().inflate(R.menu.activity_main, menu);
		// 如果运行的环境 (部署到什么版本的手机 )大于3.0
		if (android.os.Build.VERSION.SDK_INT > 11) {
			SearchView searchView = (SearchView) menu.findItem(
					R.id.action_search).getActionView();
			searchView.setOnQueryTextListener(this);// 搜索的监听
		} 
		return true;
	}
	
	/** 处理actionBar菜单条目的点击事件 */
	public boolean onOptionsItemSelected(MenuItem item) {
		if (item.getItemId() == R.id.action_search) {
			Toast.makeText(getApplicationContext(), "搜索", 0).show();
		}
		return super.onOptionsItemSelected(item);
	}

	// 当搜索提交的时候
	@Override
	public boolean onQueryTextSubmit(String query) {
		Toast.makeText(getApplicationContext(), query, 0).show();
		return true;
	}
	// 当搜索的文本发生变化
	@Override
	public boolean onQueryTextChange(String newText) {
		return true;
	}
}

实现OnQueryTextListener是搜索用的
