1：在Application中定义mTabHost

如果Radio有样式也需要定义RadioButton数组

    public static TabHost onlyTabHost=null; 
    public static RadioButton[] radios = new RadioButton[3];

2：在TabHost初始化的时候对Application中的mTabHost和radios赋值

        AiChuXingApplication.onlyTabHost=mTabHost;
        AiChuXingApplication.radios[0] = shouyerb;
        AiChuXingApplication.radios[1] = memberrb;
        AiChuXingApplication.radios[2] = morerb;

3：切换的时候

AiChuXingApplication.setCurrentTab(0);

4：在Application中定义setCurrentTab方法定义

    public static void setCurrentTab(int position){
        if (null != onlyTabHost && null != radios) {
            AiChuXingApplication.onlyTabHost.setCurrentTab(position);
            AiChuXingApplication.radios[position].setChecked(true);
        }
    }
