Apps A few different questions

[Vitality93]

Hey everyone, I didn't want to make separate topics so I decided to put all my questions into 1 topic. It's okay if you can't answer them all at once but it would be helpful if you could answer even one of them.

1.) In my table layout I have 3 buttons horizontally next to each other. Only half of the 3rd button shows. Shouldn't eclipse automatically re-size all three to make them fit whatever screen is viewing the app? Is there a way to automatically re-size them to fit each screen?
--The ScrollView, TableLayout, and Buttons all have height and width set to wrap_content

2.) Is there a way to make links change color when you click them? Sort of like 'A:visited' or 'A:hover' in CSS. Because right now, I have

android:autoLink="web"

in one of my XML files. The link is blue, but it is rather annoying not knowing if you clicked it or not until a popup appears. I'm sure there is some javascript that I can use however I would like for it to return back to a normal color once the user hits the back button... that way if they want to click it again it will still change colors.

3.) How do you embed a link inside an ImageView?

Off the top of my head I can help with the first issue. You'll get much more universal results if you set sizes with "sp" for text and "dip" for basically everything else. Here's an example of a button I had in a table layout:

<Button 
        android:text="@string/calctotal" 
	android:id="@+id/btnTotal" 
	android:layout_width="150dip" 
	android:layout_height="wrap_content">
</Button>

The "sp" and "dip" are pixel density values rather than absolute values, so if you choose the size you want relative to the screen it stays pretty consistent between devices.
