I appreciate the help, but only the text gets changed using those methods.
I also tried using an XML file like this:
(the filename is aris_theme_tab_indicator_holo.xml)
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/aris_theme_tab_unselected_holo" />
<item android:state_focused="false" android:state_selected="true" android:state_pressed="false" android:drawable="@drawable/aris_theme_tab_selected_holo" />
<!-- Focused states -->
<item android:state_focused="true" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/aris_theme_tab_unselected_focused_holo" />
<item android:state_focused="true" android:state_selected="true" android:state_pressed="false" android:drawable="@drawable/aris_theme_tab_selected_focused_holo" />
<!-- Pressed -->
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false" android:state_pressed="true" android:drawable="@drawable/aris_theme_tab_unselected_pressed_holo" />
<item android:state_focused="false" android:state_selected="true" android:state_pressed="true" android:drawable="@drawable/aris_theme_tab_selected_pressed_holo" />
<!-- Focused states -->
<item android:state_focused="true" android:state_selected="false" android:state_pressed="true" android:drawable="@drawable/aris_theme_tab_unselected_pressed_holo" />
<item android:state_focused="true" android:state_selected="true" android:state_pressed="true" android:drawable="@drawable/aris_theme_tab_selected_pressed_holo" />
</selector>
and inserted it using this code:
Dim r As Reflector
For i = 0 To 2
r.Target = tbe.GetTagWidget(tb).GetChildTabViewAt(i)
r.RunMethod2("setBackground", "aris_theme_tab_indicator_holo", "android.graphics.drawable.Drawable")
Next
but all I'm getting is this error:
java.lang.IllegalArgumentException: argument 1 should have type android.graphics.drawable.Drawable, got java.lang.String
I guess I'm missing something in my code but I don't know what that is.
EDIT: for those who might have the same problem in the future, this is how I solve this.
I inserted the XML file above using this code:
Dim ar As AndroidResources
Dim r As Reflector
For i = 0 To 2
r.Target = tbe.GetTagWidget(tb).GetChildTabViewAt(i)
Dim bg As StateListDrawable
bg.Initialize
bg.AddCatchAllState(ar.GetApplicationDrawable("aris_theme_tab_indicator_holo"))
r.RunMethod4("setBackground", Array As Object(bg), Array As String("android.graphics.drawable.Drawable"))
Next
