如何使用FragmentTabHost設置選項卡圖像？

Question

我用android.support.v4.app.FragmentTabHost編寫了一個Tab Navigation應用程序。 我想添加圖像背景到我的標籤。 代碼是在這裏：

protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_tab); 
    instance = this; 


    history = new HashMap<String, Stack<Fragment>>(); 
    tabhost = (FragmentTabHost)findViewById(android.R.id.tabhost); 

    tabhost = (FragmentTabHost)findViewById(android.R.id.tabhost); 
    tabhost.setup(this, getSupportFragmentManager(), R.id.realtabcontent); 

    TabSpec tab1 = tabhost.newTabSpec("0").setIndicator("Home"); 
    TabSpec tab2 = tabhost.newTabSpec("1").setIndicator("Sign Up"); 
    TabSpec tab3 = tabhost.newTabSpec("2").setIndicator("Tab3"); 



    System.out.print("second out"); 




    tabhost.addTab(tab1, myFragment.class, null); 
    tabhost.addTab(tab2, myFragment2.class, null); 
    tabhost.addTab(tab3, myFragment3.class, null);

可以從資源添加可繪製到TabSpec。這就是：

Resources res = getResources(); // Resource object to get Drawables 
TabHost tabHost = getTabHost(); 
TabHost.TabSpec spec; // Resusable TabSpec for each tab 

// Initialize a TabSpec for each tab and add it to the TabHost 
spec = tabHost.newTabSpec("1").setIndicator(res.getString(R.string.tabname1), 
              res.getDrawable(R.drawable.tabimage1)); 
tabHost.addTab(spec, FragmentOne.class, null); 

spec = tabHost.newTabSpec("2").setIndicator(res.getString(R.string.tabname2), 
              res.getDrawable(R.drawable.tabimage2)); 
tabHost.addTab(spec, FragmentTwo.class, null); 

spec = tabHost.newTabSpec("3").setIndicator(res.getString(R.string.tabname3), 
              res.getDrawable(R.drawable.tabimage3)); 
tabHost.addTab(spec, FragmentThree.class, null); 

//... and so on ...
