import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentTabHost;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.ImageView;
import android.widget.TabHost.TabSpec;
import android.widget.TextView;
 
/**
 * @author yangyu
 *  功能描述：自定义TabHost
 */
public class MainTabActivity extends FragmentActivity{  
  //定义FragmentTabHost对象
  private FragmentTabHost mTabHost;
  
  //定义一个布局
  private LayoutInflater layoutInflater;
  
  //定义数组来存放Fragment界面
  private Class fragmentArray[] = {FragmentPage1.class,FragmentPage2.class,FragmentPage3.class,FragmentPage4.class,FragmentPage5.class,FragmentPage6.class};
  
  //定义数组来存放按钮图片
  private int mImageViewArray[] = {R.drawable.tab_home_btn,R.drawable.tab_message_btn,R.drawable.tab_selfinfo_btn,
          R.drawable.tab_square_btn,R.drawable.tab_more_btn,R.drawable.tab_six_btn};
  
  //Tab选项卡的文字
  private String mTextviewArray[] = {"首页", "消息", "好友", "广场", "更多","six"};
  
  public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_tab_layout);
        
        initView();
    }
  
  /**
  * 初始化组件
  */
  private void initView(){
  //实例化布局对象
  layoutInflater = LayoutInflater.from(this);
    
  //实例化TabHost对象，得到TabHost
  mTabHost = (FragmentTabHost)findViewById(android.R.id.tabhost);
  mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent); 
  
  //得到fragment的个数
  int count = fragmentArray.length; 
    
  for(int i = 0; i < count; i++){  
    //为每一个Tab按钮设置图标、文字和内容
    TabSpec tabSpec = mTabHost.newTabSpec(mTextviewArray[i]).setIndicator(getTabItemView(i));
    //将Tab按钮添加进Tab选项卡中
    mTabHost.addTab(tabSpec, fragmentArray[i], null);
    //设置Tab按钮的背景
    mTabHost.getTabWidget().getChildAt(i).setBackgroundResource(R.drawable.selector_tab_background);
  }
  }
    
  /**
  * 给Tab按钮设置图标和文字
  */
  private View getTabItemView(int index){
  View view = layoutInflater.inflate(R.layout.tab_item_view, null);
  
  ImageView imageView = (ImageView) view.findViewById(R.id.imageview);
  imageView.setImageResource(mImageViewArray[index]);
  
  TextView textView = (TextView) view.findViewById(R.id.textview);  
  textView.setText(mTextviewArray[index]);
  
  return view;
  }
}




2.编写main_tab_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >
 
    <FrameLayout
        android:id="@+id/realtabcontent"
        android:layout_width="fill_parent"
        android:layout_height="0dip"
        android:layout_weight="1" />
 
    <android.support.v4.app.FragmentTabHost
        android:id="@android:id/tabhost"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" 
        android:background="@drawable/maintab_toolbar_bg">
 
        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="0dp"
            android:layout_height="0dp"
            android:layout_weight="0" />            
    </android.support.v4.app.FragmentTabHost>
 
</LinearLayout>


3.编写tab_item_view.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:orientation="vertical" >
 
    <ImageView
        android:id="@+id/imageview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:focusable="false"
        android:padding="3dp" 
        android:src="@drawable/tab_home_btn">
    </ImageView>
 
    <TextView
        android:id="@+id/textview"       
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" 
        android:text="首页"
        android:textSize="10sp"
        android:textColor="#ffffff">
    </TextView>
 
</LinearLayout>

4.编写tab_home_btn.xml

<?xml version="1.0" encoding="utf-8"?>

<selector xmlns:android="http://schemas.android.com/apk/res/android">

   <item android:drawable="@drawable/icon_home_sel" android:state_selected="true"/>

   <item android:drawable="@drawable/icon_home_nor"/>

</selector>



5.编写layout/fragment_1.xml(其他类似)

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >
 
    <ImageView
        android:id="@+id/imageview"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:scaleType="fitCenter"
        android:src="@drawable/xianjian01" >
    </ImageView>
 
</LinearLayout>

6.编写FragmentPage1.java(其他类似)

package com.yangyu.mycustomtab02;
 
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
 
public class FragmentPage1 extends Fragment{
 
  @Override
  public View onCreateView(LayoutInflater inflater, ViewGroup container,
    Bundle savedInstanceState) {
  
  return inflater.inflate(R.layout.fragment_1, null);  
  } 
}
