How to remove ImageButton's standard background image?

Question

In ImageButton I want to remove the standard button background image. In http://developer.android.com it is said, that one must define his\her own background image or set the background color to be transparent. I tried to set a black background, but it didn't make any effect...

Answer 1

You can use android:background="@null" for your ImageButton.

Answer 2

ImageButton.setBackgroundResource(0)

Answer 3

The best choice is not set a transparent background to your ImageButton.

Give to your user a feedback when the button is tapped.

android:background="?attr/selectableItemBackgroundBorderless"

Answer 4

No, it has to be transparent, not black. Try color: #00FFFFFF

use the following property in your in the xml of ImageButton:

android:background="@drawable/icon"

where icon is the name of the image kept in your drawable.

Dot't use button.setBackgroundResource(0); on some devices you will get:

Using Kotlin, you can do this:

val myImageButton = ImageButton(context).apply({
    background = null

    // and if you need to add drawable, simply use:

    setImageDrawable(ContextCompat.getDrawable(context, 
                         R.drawable.ic_save_black_24px))
})
