How to have a transparent ImageButton: Android

Answer 1

The best way is using the transparent color code

android:background="#00000000"

use the color code #00000000 for making any thing transparent

Answer 2

I was already adding something to the background so , This thing worked for me:

   android:backgroundTint="@android:color/transparent"

(Android Studio 3.4.1)

EDIT: only works on android api level 21 and above. for compatibility, use this instead

   android:background="@android:color/transparent"

Answer 3

Remove this line :

android:background="@drawable/transparent">

And in your activity class set

ImageButton btn = (ImageButton)findViewById(R.id.previous);
btn.setAlpha(100);

You can set alpha level 0 to 255

o means transparent and 255 means opaque.

Answer 4

Programmatically it can be done by :

image_button.setAlpha(0f) // to make it full transparent
image_button.setAlpha(0.5f) // to make it half transparent
image_button.setAlpha(0.6f) // to make it (40%) transparent
image_button.setAlpha(1f) // to make it opaque

Answer 5

Use this:

<ImageButton
 android:id="@+id/back"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:background="@null"
 android:padding="10dp"
 android:src="@drawable/backbtn" />

Answer 6

<ImageButton
    android:id="@+id/previous"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/media_skip_backward">
</ImageButton>

I used a transparent png for the ImageButton, and the ImageButton worked.
