java 安卓:无法在tabhost上显示指示符文本和可绘制

Question

我正在尝试在安卓上用四个标签做一个简单的标签应用。我的问题是，当我想显示图标和指示器时，它只显示文本指示器，我想在tabhost上显示可绘制和指示器文本，这是我的代码：

@Override
    protected void onCreate(Bundle savedInstanceState) {
        //hide title bar
                BasicDisplaySettings.toggleTaskBar(SimasCardMainActivity.this, false);
                //show status bar
                BasicDisplaySettings.toggleStatusBar(SimasCardMainActivity.this, true);

        super.onCreate(savedInstanceState);
        setContentView(R.layout.simascard);

        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

        // Create an Intent to launch an Activity for the tab (to be reused)
        intent = new Intent().setClass(this, TerbaruSimasCard.class);
        spec = tabHost.newTabSpec("Terbaru").setIndicator("Terbaru",
                  res.getDrawable(R.drawable.menu_terbaru))
                  .setContent(intent);
        tabHost.addTab(spec);

        intent = new Intent().setClass(this, MerchantSimasCard.class);
        spec = tabHost.newTabSpec("Merchant").setIndicator("Merchant",
                  res.getDrawable(R.drawable.menu_merchant))
                  .setContent(intent);
        tabHost.addTab(spec);

        intent = new Intent().setClass(this, TentangSimasCard.class);
        spec = tabHost.newTabSpec("Tentang").setIndicator("Tentang",
                  res.getDrawable(R.drawable.menu_tentang))
                  .setContent(intent);
        tabHost.addTab(spec);

        intent = new Intent().setClass(this, FaqSimasCard.class);
        spec = tabHost.newTabSpec("FAQ").setIndicator("FAQ",
                  res.getDrawable(R.drawable.menu_faq))
                  .setContent(intent);
        tabHost.addTab(spec);


        for (int i = 0; i < tabHost.getTabWidget().getChildCount(); i++){
            tabHost.getTabWidget().getChildAt(i).setPadding(0,0,0,0);
            tabHost.getTabWidget().getChildTabViewAt(i).setBackgroundDrawable(null);
        }
        tabHost.setCurrentTab(0);
    }

//  @Override
    public void onBackPressed() {
     finish();
    }

当我使用

spec = tabHost.newTabSpec("Tentang").setIndicator("",
                      res.getDrawable(R.drawable.menu_tentang))
                      .setContent(intent);

它将显示一个图标，但当我在setIndicator上添加文本时，例如setIndicator("Tentang")它只在tabhost上显示指示符文本，我不知道我的代码哪里出了问题，我试图增加选项卡高度，但没有用，我希望有人能帮助我解决我的问题。多谢各位

删除此tabHost.getTabWidget().getChildTabViewAt(i).setBackgroundDrawable(null);

并将其替换为

tabHost.getTabWidget().getChildAt(i).setBackgroundResource(R.drawable.menu_tentang);

我已经这样做了，它工作得很好

Resources ressources = getResources(); 
    TabHost tabHost = getTabHost();

    Intent addfriend = new Intent().setClass(this, yourclass1.class);
    Intent mailfriend = new Intent().setClass(this, yourclass2.class);
    tabHost.addTab(tabHost.newTabSpec("child1").setIndicator("your tag",getResources().getDrawable(R.drawable.youpng)).setContent(addfriend));
    tabHost.addTab(tabHost.newTabSpec("child1").setIndicator("your tag",getResources().getDrawable(R.drawable.yourpng)).setContent(mailfriend));



    tabHost.getTabWidget().getChildAt(0).setBackgroundColor(getResources().getColor(R.color.anycolor));
    tabHost.getTabWidget().getChildAt(0).setBackgroundResource(R.drawable.yourpng);

    tabHost.getTabWidget().getChildAt(1).setBackgroundColor(getResources().getColor(R.color.anycolor));
    tabHost.getTabWidget().getChildAt(1).setBackgroundResource(R.drawable.youpng);
