TabHosts导航按钮实现自定义图片和文字

主要代码

package com.cc.selftabhost;

import android.app.TabActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;

/**
* @author cc
* 1.TabHostActivity extends TabActivity
* 2. TabHost tabhost = getTabHost();
* 3.需要介个页面就创建几个空的TabActivity，并在manifest注册
* 4.几个tab导航按钮，就创建几个xml 按钮的布局，比如上边图片下边文字。图片的位置可以使用selector控制焦点获取变换图片
*
* 【5-9 重复添加多个标签】
* 5.创建标签 TabSpec tabSpec01 = tabhost.newTabSpec("tab1");
* 6.填充导航按钮的布局 tabSpec01.setIndicator(View.inflate(TabHostMainActivity.this,R.layout.tab_main, null));
* 7.Intent跳转
* 8.标签 setContent 意图
* 9.tabhost.addTab 加载 标签。

public class TabHostMainActivity extends TabActivity {

@Override

// 继承 tabActivity，得到tabHost

TabSpec tabSpec01 = tabhost.newTabSpec("tab1");
// 设置tab 导航按钮的布局

// 添加意图跳转
Intent intent1 = new Intent(TabHostMainActivity.this,
TabMainActivity.class);
// 设置标题对应的内容
tabSpec01.setContent(intent1);
// 添加到tab中
tabhost.addTab(tabSpec01);
