推荐答案
这<一个href=\"http://stackoverflow.com/questions/14722654/tabwidget-current-tab-bottom-line-color\">answer解决了我的问题。
将此code你设置你的标签之后:
Add this code after you setup your tabs :
TabHost host = (TabHost)view.findViewById(R.id.tab_host);
TabWidget widget = host.getTabWidget();
for(int i = 0; i < widget.getChildCount(); i++) {
View v = widget.getChildAt(i);
// Look for the title view to ensure this is an indicator and not a divider.
TextView tv = (TextView)v.findViewById(android.R.id.title);
if(tv == null) {
continue;
}
v.setBackgroundResource(R.drawable.tab_indicator_ab_dgrey);
}
然后就可以从删除以下code你的 styles.xml
:
<item name="android:actionBarTabStyle">@style/ActionBarTabStyle.Dgrey</item>
和
<style name="ActionBarTabStyle.Dgrey" parent="@android:style/Widget.Holo.ActionBar.TabView">
<item name="android:background">@drawable/tab_indicator_ab_dgrey</item>
</style>
