Java Android TabHost更改底部栏的颜色

搜索这个已经有一段时间了，努力让任何东西都能正常工作

我需要将蓝色底部栏的颜色更改为十六进制值，我已经更改了选项卡的背景颜色，但它没有更改TanHost上的蓝色。真的有可能改变这一点吗？我看到youtube把它做成了一个漂亮的红色，所以它一定是可行的！这是设置选项卡主机：

选项卡是由它们自己的类控制的片段

// set up the tabhost
         mTabHost = (FragmentTabHost)findViewById(android.R.id.tabhost);
            mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);
            mTabHost.addTab(mTabHost.newTabSpec("event").setIndicator("Event Locations",
                    getResources().getDrawable(R.drawable.ic_event_tab)),
                    EventFragment.class, null);
            mTabHost.addTab(mTabHost.newTabSpec("itin").setIndicator("Itinerary",
                    getResources().getDrawable(R.drawable.ic_itin_tab)),
                       ItineraryFragment.class, null);
            mTabHost.addTab(mTabHost.newTabSpec("info").setIndicator("Kendal Info",
                    getResources().getDrawable(R.drawable.ic_info_tab)),
                    KendalInfoFragment.class, null);

            mTabHost.getTabWidget().setBackgroundColor(Color.RED);

假设不推荐使用的库一如既往地工作，这是我用来给选项卡上色的过程。我只是在代码中设置了背景，如下所示，因为它在xml中无法直接访问：

 TabWidget tabs = (TabWidget)getTabWidget();            
        for (int i = 0; i<tabs.getChildCount(); i++) {
            RelativeLayout tab = (RelativeLayout) tabs.getChildAt(i);
            tab.setBackgroundDrawable(this.getResources().getDrawable(R.drawable.tabindicator));

TabWidget tabs=（TabWidget）getTabWidget（）；
对于（int i=0；i
