2：RadioButton的style="@style/main_tab_bottom"文件

 <style name="main_tab_bottom">
        <item name="android:textSize">10.0dip</item>
        <item name="android:textColor">#ffffffff</item>
        <item name="android:ellipsize">marquee</item>

</selector>

 

4：主类里的调用代码：（class MainActivity extends TabActivity）：

public TabHost mth;
 public static final String TAB_HOME="首页";
 public static final String TAB_MSG="信息";

//----------------------------------

mth=this.getTabHost();
       
        TabSpec ts1=mth.newTabSpec(TAB_HOME).setIndicator(TAB_HOME);
        ts1.setContent(new Intent(MainActivity.this,FirstActivity.class));
        mth.addTab(ts1);
       
        TabSpec ts2=mth.newTabSpec(TAB_MSG).setIndicator(TAB_MSG);
        ts2.setContent(new Intent(MainActivity.this,SecondActivity.class));
        mth.addTab(ts2);
       
        this.radioGroup=(RadioGroup)findViewById(R.id.main_radio);
        radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {
   
   @Override
   public void onCheckedChanged(RadioGroup group, int checkedId) {
    // TODO Auto-generated method stub
    
    switch(checkedId){
    case R.id.radio_button0:
     mth.setCurrentTabByTag(TAB_HOME);
     break;
    case R.id.radio_button1:
     mth.setCurrentTabByTag(TAB_MSG);
     break;
    case R.id.radio_button2:
     mth.setCurrentTabByTag(TAB_HOME);
     break;
    case R.id.radio_button3:
     mth.setCurrentTabByTag(TAB_MSG);
     break;
    case R.id.radio_button4:
     mth.setCurrentTabByTag(TAB_HOME);
     break;
    }
   }
  });
