您好rakesh，您可以使用该链接在底部设置标签custom tabs 并查看此示例代码

public class Tab App extends Tab Activity {

@覆盖 protected void onCreate（Bundle savedInstanceState）{ super.onCreate（savedInstanceState）;

    Resources res = getResources(); // Resource object to get Drawables
    TabHost tabHost = getTabHost();  // The activity TabHost
    TabHost.TabSpec spec;  // Resusable TabSpec for each tab
    Intent intent;  // Reusable Intent for each tab
    tabHost.removeAllViews();
    TabWidget tabs = new TabWidget(this);
    tabs.setId(android.R.id.tabs);
    RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
    params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
    tabs.setLayoutParams(params);
    FrameLayout content = new FrameLayout(this);
    content.setId(android.R.id.tabcontent);
    content.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
    RelativeLayout relative = new RelativeLayout(this);
    relative.setLayoutParams(new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
    relative.addView(content);
    relative.addView(tabs);
    tabHost.addView(relative);
    tabHost.setup();

    // Create an Intent to launch an Activity for the tab (to be reused)
    intent = new Intent().setClass(this, AndroidBrowser.class);

    // Initialize a TabSpec for each tab and add it to the TabHost
    spec = tabHost.newTabSpec("tag1")
      .setIndicator("tag1",res.getDrawable(R.drawable.cw))
                              .setContent(intent);
    tabHost.addTab(spec);

    // Do the same for the other tabs
    intent = new Intent().setClass(this, CWBrowser.class);
    spec = tabHost.newTabSpec("tag2")
      .setIndicator("tag2",res.getDrawable(R.drawable.cw))
                              .setContent(intent);
    tabHost.addTab(spec);

    intent = new Intent().setClass(this, CWBrowser.class);
    spec = tabHost.newTabSpec("tag3")
      .setIndicator("tag3",res.getDrawable(R.drawable.cw))
                              .setContent(intent);
    tabHost.addTab(spec);

    tabHost.setCurrentTab(0);
}`
