自己改的自定义tabhost组建，效果图如左。有更好的朋友可以相互交流一下，嘿嘿。

1.先上AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.priscilla"
    android:versionCode="1"
    android:versionName="1.0" >

<uses-sdk android:minSdkVersion="7" />

</manifest>

2 MyTab.java

package com.priscilla;

import java.util.ArrayList;
import java.util.List;
import java.util.Map;
import java.util.WeakHashMap;

import android.app.TabActivity;
import android.content.Context;
import android.content.Intent;
import android.content.res.Resources;
import android.os.Bundle;
//import android.view.LayoutInflater;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.TabHost;
import android.widget.TabWidget;
import android.widget.TextView;
import android.widget.TabHost.TabSpec;

public class MyTab extends TabActivity {
/** Called when the activity is first created. */

private TabHost mTabhost;
private TabWidget mTabWidget;
private LayoutInflater mInflater;
private List<TextView> mtext;
private List<TabSpec> mTabSpec;
private List<LinearLayout> linearLayout;
private List<Intent> intent;
private Context mContext;

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

mContext = this;
mInflater = LayoutInflater.from(this);

  // mTabhost = this.getTabHost();// 从TabActivity上面获取放置Tab的TabHost
  mTabhost = (TabHost) findViewById(android.R.id.tabhost);
  mTabWidget = (TabWidget) findViewById(android.R.id.tabs);

  mTabSpec = new ArrayList<TabSpec>();
  linearLayout = new ArrayList<LinearLayout>();
  mtext = new ArrayList<TextView>();
  intent = new ArrayList<Intent>();

creatTab();

  /*
   * mTabhost.addTab(mTabhost .newTabSpec("选项卡1") .setIndicator(
   * (LinearLayout) LayoutInflater.from(this).inflate( R.layout.tabwidget,
   * null)) .setContent(R.id.linearLayout01)); mTabhost.addTab(mTabhost
   * .newTabSpec("选项卡2") .setIndicator( (LinearLayout)
   * LayoutInflater.from(this).inflate( R.layout.tabwidget, null))
   * .setContent(R.id.linearLayout02)); mTabhost.addTab(mTabhost
   * .newTabSpec("选项卡3") .setIndicator( (LinearLayout)
   * LayoutInflater.from(this).inflate( R.layout.tabwidget, null))
   * .setContent(R.id.linearLayout03));
   */

// 设置当前显示哪一个标签
// mTabhost.setCurrentTab(0);

  // 去tabwidget白线,这个对默认主题有效
  /*
   * mTabhost.setPadding(mTabhost.getPaddingLeft(),
   * mTabhost.getPaddingTop(), mTabhost.getPaddingRight(),
   * mTabhost.getPaddingBottom() - 5);
   */
}

public void creatTab() {

  for (int i = 0; i < 3; i++) {
   mTabSpec.add(mTabhost.newTabSpec("tab" + i));
   linearLayout.add((LinearLayout) mInflater.inflate(
     R.layout.tabwidget, null));
   mtext.add((TextView) linearLayout.get(i)
     .findViewById(R.id.tab_name));
   mtext.get(i).setText(
     mContext.getResources().getString(R.string.tab_name,
       String.valueOf(i)));
   mTabSpec.get(i).setIndicator(linearLayout.get(i));
   //mTabSpec.get(i).setContent(list.get(i));
   intent.add(new Intent(mContext, TabContent.class));
   Log.v("---whty---", mTabSpec.get(i).getTag());
   Bundle buddle = new Bundle();
   buddle.putString("tab", mTabSpec.get(i).getTag());
   intent.get(i).putExtras(buddle);

   mTabSpec.get(i).setContent(intent.get(i));

mTabhost.addTab(mTabSpec.get(i));

}
}

}

2.TabContent.java

package com.priscilla;

import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.widget.ImageView;
import android.widget.TextView;

public class TabContent extends Activity {

private TextView textView;
private ImageView imgView;

@Override
protected void onCreate(Bundle savedInstanceState) {
  // TODO Auto-generated method stub
  super.onCreate(savedInstanceState);
  setContentView(R.layout.tabcontent);

textView = (TextView) findViewById(R.id.TextView);
imgView = (ImageView) findViewById(R.id.ImageView);

Bundle buddle = this.getIntent().getExtras();
String flag = buddle.getString("tab");

  if ("tab0".equals(flag)) {
   textView.setText(getResources().getString(R.string.andy));
   Bitmap bitmap = BitmapFactory.decodeResource(getResources(),
     R.drawable.andy);
   imgView.setImageBitmap(bitmap);
  }

  if ("tab1".equals(flag)) {
   textView.setText(getResources().getString(R.string.bill));
   Bitmap bitmap = BitmapFactory.decodeResource(getResources(),
     R.drawable.bill);
   imgView.setImageBitmap(bitmap);
  }

  if ("tab2".equals(flag)) {
   textView.setText(getResources().getString(R.string.linux));
   Bitmap bitmap = BitmapFactory.decodeResource(getResources(),
     R.drawable.torvalds);
   imgView.setImageBitmap(bitmap);
  }

}
