Transparent picture in ImageButton does not display transparency

This is my transparent image:

enter image description here

But when I apply it to my app, the image not transparent, as shown below:

enter image description here

Why would the following code produce this behaviour?

<ImageButton
    android:layout_width="30dp"
    android:layout_height="30dp"
    android:id="@+id/back"
    android:layout_gravity="center_vertical"
    android:src="@drawable/back"/>

Activity:

ImageButton back = (ImageButton) findViewById(R.id.back);
back.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Back();
    }
});

Try this

you are use the direct drawable instead of src

  <ImageButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"

    android:background="@drawable/back"

   />

Note: if Your back image is white than should be your main layout or back ImageButton back layout background not white....

you can try this 

<ImageButton
  android:layout_width="30dp"
  android:layout_height="30dp"
  android:id="@+id/back"
  android:layout_gravity="center_vertical"
  android:src="@drawable/back" 
  android:background="@android:color/transparent"/>

if it does not work, try setting a background to another color (just to make sure that the src image is pointing to the correct drawable)

edit: also remove all tints if you have them, to see if it affects the results.

You need to set android:background = "@null"

  <ImageButton 
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:src="@drawable/ic_action_exit"
  android:background="@null"/>

put your drawable name instead of ic_action_exit.

this should give transparent background.
