推荐答案

您可以更改Tabhost文本的颜色如下。

You may change color of Tabhost text as follow.

tabHost.setOnTabChangedListener(new OnTabChangeListener() {

    @Override
    public void onTabChanged(String tabId) {

        for (int i = 0; i < tabHost.getTabWidget().getChildCount(); i++) {
            tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.parseColor("#FF0000")); // unselected
            TextView tv = (TextView) tabhost.getTabWidget().getChildAt(i).findViewById(android.R.id.title); //Unselected Tabs
            tv.setTextColor(Color.parseColor("#ffffff"));
        }

        tabHost.getTabWidget().getChildAt(tabHost.getCurrentTab()).setBackgroundColor(Color.parseColor("#0000FF")); // selected
        TextView tv = (TextView) tabhost.getCurrentTabView().findViewById(android.R.id.title); //for Selected Tab
        tv.setTextColor(Color.parseColor("#000000"))

    }
});

编辑：

要初步确定文本颜色在您的活动，您可以使用 onResume这code（）功能

To set text color initially in your activity, you can use this code in onResume() function

TabHost tabhost = getTabHost();
    for(int i=0;i<tabhost.getTabWidget().getChildCount();i++) 
    {
        TextView tv = (TextView) tabhost.getTabWidget().getChildAt(i).findViewById(android.R.id.title);
        tv.setTextColor(Color.parseColor("#000000"));
    }
