Make buttons work

Question

How do I add a button on a background image in Android?

I already added the background now I want to add a button and make it work within the background. I have tried to add multiple buttons but then they all don't work, I'm not sure if its the layout or something else.

This is what I have so far:

    <Button
    style="?android:attr/buttonStyleSmall"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="back"
    android:id="@+id/button2"
    android:layout_alignTop="@+id/button"
    android:background="@drawable/scan1"
    android:layout_centerHorizontal="true"
    android:layout_alignParentStart="false"
    android:layout_alignParentLeft="false" />

i edited the code, so the "scan1" drawable is showing red.

Answer 1

Transparent button

 android:background="@null"

or

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

Answer 2

Use FancyButtons library to create buttons with transparent background. Set fb_defaultColor param as follows:

fancy:fb_defaultColor="@android:color/transparent"

Using this library, you won't lose ripple effects on button clicks.

Answer 3

 android:background="?android:attr/selectableItemBackground"

Add this to your button xml.. Hope it helps

Answer 4

You may also use: in your xml:

android:background="@null"

or in code:

button.setBackgroundColor(Color.TRANSPARENT);
