Android Tabactivity-如何在选择标签时更改图标图像

Question

In my tabactivity, I display icon that I get from the database, by creating an ImageView and passsing this to the setIndicator method. I have only one image for each tab, so I was wondering if there is way to just change the color of the image alone (as opposed to changing the tab's color) when a tab is selected? Also is it possible to hide the gray line that is being drawn at the bottom of the tabs when a tab is selected? Any help is appreciated..thanks

Hiding gray line:

yourTabWidget.setStripEnabled(false);

Setting custom image per tab state:

tabitemicon.xml:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- When selected, use grey -->
    <item android:drawable="@drawable/orange"
          android:state_selected="true" />
    <!-- When not selected, use white-->
    <item android:drawable="@drawable/white" />
</selector>

Java code:

tabHost = getTabHost():
tabHost.newTabSpec("test").setIndicator("My Tab Title",
                          res.getDrawable(R.drawable.tabitemicon))
                      .setContent(someIntent);
