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

<pre><code>&lt;ImageButton
android:id="@+id/imageButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/icon" 
android:background="#00000000"
/&gt;
</code></pre>

works beautifully

I'm having the same problem but now it has been solved. If you are using <code>&quot;android:background=&quot;@null&quot;</code> it will resulted of no background at all and no button pressed animation will be appeared to the user.
Just adding this line of code to make an image button become flashing upon clicked. This is the proper way to alert the user an image button has been clicked.
<pre><code> &quot;android:background=&quot;?android:selectableItemBackground&quot; 
</code></pre>

if you set the

instead of

it should overwrite the gray background

blocks|key|635421|text|嗯。如果您拖动ImageButton，通常会提示输入ImageSource。但是ImageSource(android:src)并没有去掉灰色背景。这是一个应该放在背景之上的图像：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|635422|而不是在布局XML中尝试android:background。|635423|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Yeah. If you drag ImageButton that will usually ask for ImageSource. But the ImageSource(android:src) doesn't remove the gray background. It is an image that should be on top of background:

Instead of that try android:background in layout XML.

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?

Any way to remove the grey background from ImageButtons?

我有一个ImageButton和我想删除丑陋(IMHO)的背景，周围的图像。我可以只添加一个ImageView，但它们很难完美地设置在如图所示的灰色布局中。[重力“中心”不会使它居中，只是垂直居中。)那么有什么方法可以去掉它吗？​​
