网上已经有很多关于如何将TabHost的标签放在底部，这里就不说了

主要是把这些都做成框架，只需要提供图片和文字就可以实现这样的效果。

直接上图，代码解释的很清楚

程序的图片借用新浪微博.

 

使用代码:

package com.api.example.app;
 
import java.util.ArrayList;
import java.util.List;
 
import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.TabWidget;
import android.widget.TextView;
 
import com.api.R;
import com.api.TabHostActivity;
 
/**
* 整个流程就像使用ListView自定BaseAdapter一样
 
* 
* 如果要自定义TabHostActivity的Theme，并且不想要头部阴影
* 一定要添加这个android:windowContentOverlay = null
 
* 
* 如果想在别的项目里面使用TabHostActivity
* 可以项目的属性里面找到Android，然后在Library部分添加这个项目(Api)
* <a href='\"http://www.cnblogs.com/qianxudetianxia/archive/2011/05/01/2030232.html\"' target='\"_blank\"'>如何添加</a>

public class ExampleActivity extends TabHostActivity {
 
List mItems;
private LayoutInflater mLayoutInflater;
 
/**在初始化TabWidget前调用
* 和TabWidget有关的必须在这里初始化*/
@Override
protected void prepare() {
TabItem home = new TabItem(
"首页", // title
R.drawable.icon_home, // icon
R.drawable.example_tab_item_bg, // background
new Intent(this, Tab1Activity.class)); // intent
 
TabItem info = new TabItem(
"资料",
R.drawable.icon_selfinfo,
R.drawable.example_tab_item_bg,
new Intent(this, Tab2Activity.class));
 
TabItem msg = new TabItem(
"信息",
R.drawable.icon_meassage,
R.drawable.example_tab_item_bg,
new Intent(this, Tab3Activity.class));
 
TabItem square = new TabItem(
"广场",
R.drawable.icon_square,
R.drawable.example_tab_item_bg,
new Intent(this, Tab4Activity.class));
 
TabItem more = new TabItem(
"更多",
R.drawable.icon_more,
R.drawable.example_tab_item_bg,
new Intent(this, Tab5Activity.class));
 
mItems = new ArrayList();
mItems.add(home);
mItems.add(info);
mItems.add(msg);
mItems.add(square);
mItems.add(more);
 
// 设置分割线
TabWidget tabWidget = getTabWidget();
tabWidget.setDividerDrawable(R.drawable.tab_divider);
 
mLayoutInflater = getLayoutInflater();
}
 
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setCurrentTab(0);
}
 
/**tab的title，icon，边距设定等等*/
@Override
protected void setTabItemTextView(TextView textView, int position) {
textView.setPadding(3, 3, 3, 3);
textView.setText(mItems.get(position).getTitle());
textView.setBackgroundResource(mItems.get(position).getBg());
textView.setCompoundDrawablesWithIntrinsicBounds(0, mItems.get(position).getIcon(), 0, 0);
 
}
 
/**tab唯一的id*/
@Override
protected String getTabItemId(int position) {
return mItems.get(position).getTitle(); // 我们使用title来作为id，你也可以自定
}
 
/**点击tab时触发的事件*/
@Override
protected Intent getTabItemIntent(int position) {
return mItems.get(position).getIntent();
}
 
@Override
protected int getTabItemCount() {
return mItems.size();
}
 
/**自定义头部文件*/
@Override
protected View getTop() {
return mLayoutInflater.inflate(R.layout.example_top, null);
}
 
}

// set theme because we do not want the shadow
setTheme(R.style.Theme_Tabhost);
setContentView(R.layout.api_tab_host);
 
mLayoutflater = getLayoutInflater();
 
mTabHost = getTabHost();
mTabWidget = getTabWidget();
//mTabWidget.setStripEnabled(false); // need android2.2
 
prepare();
 
initTop();
initTabSpec();
}
 
private void initTop() {
View child = getTop();
LinearLayout layout = (LinearLayout) findViewById(R.id.tab_top);
layout.addView(child);
}
 
private void initTabSpec() {
 
int count = getTabItemCount();
 
for (int i = 0; i < count; i++) {
// set text view
View tabItem = mLayoutflater.inflate(R.layout.api_tab_item, null);
 
TextView tvTabItem = (TextView) tabItem.findViewById(R.id.tab_item_tv);
setTabItemTextView(tvTabItem, i);
// set id
String tabItemId = getTabItemId(i);
// set tab spec
TabSpec tabSpec = mTabHost.newTabSpec(tabItemId);
tabSpec.setIndicator(tabItem);
tabSpec.setContent(getTabItemIntent(i));
 
mTabHost.addTab(tabSpec);
}
 
}
 
/** 在初始化界面之前调用 */
protected void prepare() {
// do nothing or you override it
}
 
/** 自定义头部布局 */
protected View getTop() {
// do nothing or you override it
return null;
}
 
protected int getTabCount() {
return mTabHost.getTabWidget().getTabCount();
}
 
/** 设置TabItem的图标和标题等*/
abstract protected void setTabItemTextView(TextView textView, int position);
 
abstract protected String getTabItemId(int position);
 
abstract protected Intent getTabItemIntent(int position);
 
abstract protected int getTabItemCount();
 
protected void setCurrentTab(int index) {
