Any way to remove the grey background from ImageButtons?

Question

I have an ImageButton and I'd like to remove the ugly (IMHO) background that surrounds the Image. I could just add an ImageView, but they're very hard to get set perfectly in a Layout like the grey one pictured. [gravity "Center" doesn't make it go to the middle, just centers it Vertically.)

So any way to remove that?

Answer 1

Just use android:background="#0000" (#0000 same with #00000000) or

ImageButton imageButton = new ImageButton(this);
imageButton.setBackgroundDrawable(null);

Answer 2

The default background is not transparent.

So, just add the transparent color "#00000000" as you background, then you could solve it.

p.s. #00000000 is the transparent color

<ImageButton
android:id="@+id/imageButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/icon" 
android:background="#00000000"
/>

Answer 3

You can keep the square box and just change its color like this:

android:backgroundTint="@color/colorPrimary"

works beautifully
