Android Can'；t更改碎片选项卡主机选项卡的指示器颜色

我想在我的应用程序中实现一个自定义FragmentTabHost。关于这个主题的文档是有限的，我无法让它与我的自定义指示器绘图（绿色）一起工作，它们不会显示在选项卡按钮下

我只得到默认的蓝色指示器。有什么不对劲？ 谢谢

我遇到了这样的问题，我用下面的代码语句解决了它：

mTabHost.getTabWidget().getChildAt(mTabHost.getCurrentTab()).setBackgroundResource(R.drawable.tab_selected);

祝你好运

mTabHost.getTabWidget().getChildAt(mTabHost.getCurrentTab()).setBackgroundResource(R.drawable.tab_selected);
