Abhi,
I am a little confused - you mentioned changing button state and then
talk about focus.
Enabled/disabled state is one thing, and focus is quite another.
Try calling:
button.setEnabled(true or false)
Note that for an ImageButton you need to have a state drawable like this
to select image depending on the button's state.
// my_button_selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android";>
<item android:state_enabled="false"
android:drawable="@drawable/my_button_disabled" />
<item android:drawable="@drawable/my_button_normal" />
</selector>
my_button_disabled and my_button_normal are images (.png or .9.png)
// in layout xml
<ImageButton ..... android:src="@drawable/my_button_selector"

Guys,
I am trying to get the button in my layout to have focus as I am
programmatically changing its state. My application is a video player
using VideoView. I am toggling the state of the button based on where
my video is. So basically, I am doing videoview.getCurrentPosition()
and if it is in a certain window, I want to toggle my Button state
(enabled to disabled and vice versa). The layout is LinearLayout and I
have the VideoView and Button layed horizontally. When I first had the
MediaController in my Video, the button would change focus on touching
the videoview (which is when the MediaController would pop up). I
later removed the controller because I didn't want the button state to
change when the user touches the screen. I want it to change
automatically.
I tried all sorts of combinations possible. button.setFocusable(),
button.requestFocus(), button.bringToFront() and so on. But none of
them seem to work.
Is there any way I can make it toggle programatically and without user
intervention through touch? or is it impossible to do it with the
VideoView?
Thanks,
Abhi
