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

How I can acomplish same thing using java code? Something like ib.setBackgroundColor(???);

Solution 1:

This is the simple only you have to set background color as transparent

    ImageButton btn=(ImageButton)findViewById(R.id.ImageButton01);
    btn.setBackgroundColor(Color.TRANSPARENT);

Solution 2:

Do it in your xml

<ImageButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/imageButtonSettings"
        android:layout_gravity="right|bottom"
        android:src="@drawable/tabbar_settings_icon"
        android:background="@android:color/transparent"/>

This should work - imageButton.setBackgroundColor(android.R.color.transparent);
