1.创建android项目tabHostDemo,在包com.yinlans下创建MainActivity.java对应的布局文件main.xml

2.main.xml布局文件代码如下：

 <?xml version=”1.0″ encoding=”utf-8″?> 
<LinearLayout  xmlns:android=”http://schemas.android.com/apk/res/android”
    android:id=”@+id/framelayout01″
    android:layout_width=”fill_parent” 
    android:layout_height=”fill_parent”> 
   <TabHost
       android:id=”@+id/tabhost”
       android:layout_width=”fill_parent”
       android:layout_height=”fill_parent” >
       <LinearLayout
           android:layout_width=”fill_parent”
           android:layout_height=”fill_parent”
           android:orientation=”vertical”>

<!–注意TabWidget的 android:layout_height=”wrap_content”–>
           <TabWidget
               android:id=”@android:id/tabs”
               android:layout_width=”fill_parent”
              android:layout_height=”wrap_content”></TabWidget>
           <FrameLayout
               android:id=”@android:id/tabcontent”
               android:layout_width=”fill_parent”
               android:layout_height=”wrap_content”
               android:layout_weight=”1″>
               <LinearLayout
               android:id=”@+id/llayout1″
              android:layout_width=”fill_parent”
              android:layout_height=”fill_parent”
              android:orientation=”vertical”>
                   <ListView
                       android:id=”@+id/listview1″
                       android:layout_width=”fill_parent”
                       android:layout_height=”wrap_content”></ListView>
               </LinearLayout>
                <LinearLayout
                     android:id=”@+id/llayout2″
                     android:layout_width=”fill_parent”
                     android:layout_height=”fill_parent”
                     android:orientation=”vertical”>
                   <ListView
                       android:id=”@+id/listview2″
                       android:layout_width=”fill_parent”
                       android:layout_height=”wrap_content”></ListView>
               </LinearLayout>
           </FrameLayout>
       </LinearLayout>
   </TabHost>
</LinearLayout>

3.MainActivity.java代码如下：

package com.yinlans;

import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.widget.TabHost;
import android.widget.TabWidget;
import android.widget.TextView;

public class MainActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);//去掉主页的标题
        setContentView(R.layout.main);
       TabHost tabHost=(TabHost) this.findViewById(R.id.tabhost);
       tabHost.setup();
       TabWidget tabWidget=tabHost.getTabWidget();
       tabHost.addTab(tabHost.newTabSpec(“all”).setContent(R.id.llayout1).setIndicator(“全部相薄”));
       tabHost.addTab(tabHost.newTabSpec(“we”).setContent(R.id.llayout2).setIndicator(“我的收藏”));
       //注意 这个就是改变TabHost默认样式，必须放在上面这段代码的下面，不然改变不了
       for(int i=0;i<tabWidget.getChildCount();i++){
        tabWidget.getChildAt(i).getLayoutParams().height=50;
        tabWidget.getChildAt(i).getLayoutParams().width=65;
        TextView tv=(TextView) tabWidget.getChildAt(i).findViewById(android.R.id.title);
        tv.setTextSize(15);
        tv.setTextColor(this.getResources().getColorStateList(android.R.color.white));
       }
    }
}
