android TabHost解决下面白线

  我之前做分页都是用GridView和ActivityGroup实现的.因为觉得TabHost不好用,还有就是自己水平差的原因吧.如果帮的话,重写view任何问题都可以解决,呵呵,下面请看实现过程,其实很简单.
      针对TabHost的运用,我就不多讲解了,网上例子好多,或者你也可以下载我的Demo查看,不过先声明,写的不好.
      代码片段:
[java] 
public class MyActivity extends TabActivity { 
    private TabWidget tabWidget; 
 
    /** Called when the activity is first created. */ 
    public void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState); 
        setContentView(R.layout.main); 
 
        Resources res = getResources(); // Resource object to get Drawables 
        final TabHost tabHost = getTabHost(); // The activity TabHost 
        TabHost.TabSpec spec; // Resusable TabSpec for each tab 
        Intent intent; // Reusable Intent for each tab 
 
        // Create an Intent to launch an Activity for the tab (to be reused) 
        intent = new Intent().setClass(this, ArtistsActivity.class); 
 
        // Initialize a TabSpec for each tab and add it to the TabHost 
        spec = tabHost 
                .newTabSpec("artists") 
                .setIndicator("Artists", 
                        res.getDrawable(R.drawable.ic_tab_artists)) 
                .setContent(intent); 
        tabHost.addTab(spec); 
 
        // Do the same for the other tabs 
        intent = new Intent().setClass(this, AlbumsActivity.class); 
        spec = tabHost 
                .newTabSpec("albums") 
                .setIndicator("Albums", 
                        res.getDrawable(R.drawable.ic_tab_artists)) 
                .setContent(intent); 
        tabHost.addTab(spec); 
 
        intent = new Intent().setClass(this, SongsActivity.class); 
        spec = tabHost 
                .newTabSpec("songs") 
                .setIndicator("Songs", 
                        res.getDrawable(R.drawable.ic_tab_artists)) 
                .setContent(intent); 
        tabHost.addTab(spec); 
        tabHost.setCurrentTab(2); 
        View v; 
        tabWidget = tabHost.getTabWidget(); 
 
        for (int i = 0; i < tabWidget.getChildCount(); i++) { 
            // 获取tabview项 
            v = tabWidget.getChildAt(i); 
            // 设置tab背景颜色 
            v.setBackgroundResource(android.R.color.white); 
            // 获取textview控件,(默认为白色) 
            TextView textView = (TextView) v.findViewById(android.R.id.title); 
            textView.setTextColor(Color.BLACK); 
            // 默认选项要处理 
            if (tabHost.getCurrentTab() == i) 
                v.setBackgroundResource(R.drawable.renren_sdk_pay_repair_btn); 
        } 
        // tabchanged的监听 
        tabHost.setOnTabChangedListener(new OnTabChangeListener() { 
            // tabId显示的是:newTabSpec里面的值 
            @Override 
            public void onTabChanged(String tabId) { 
                // 首先把所有的view背景初始化了. 
                for (int i = 0; i < tabHost.getTabWidget().getChildCount(); i++) { 
                    View v = tabHost.getTabWidget().getChildAt(i); 
                    // 设置tab背景颜色 
                    v.setBackgroundResource(android.R.color.white); 
                    // 选中的进行处理 
                    if (tabHost.getCurrentTab() == i) { 
                        v.setBackgroundResource(R.drawable.renren_sdk_pay_repair_btn); 
                    } 
 
                }
