Answer 1

If you don't mind hardcoding it you can do this ~> android:background="#eeeeee" and drop any hex color # you wish.

Looks like this....

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentRight="true"
    android:layout_below="@+id/textView1"
    android:text="@string/ClickMe"
    android:background="#fff"/>

Answer 2

In order to keep the style, use:

int color = Color.parseColor("#99cc00");
button.getBackground().mutate().setColorFilter(new PorterDuffColorFilter(color, PorterDuff.Mode.SRC));

Answer 3

With version 1.2.0-alpha06 of material design library, now we can use android:background="..." on MaterialButton components:

<com.google.android.material.button.MaterialButton
    android:background="#fff"
    ...
/>

Answer 4

Why not just use setBackgroundColor(getResources().getColor(R.color.holo_light_green))?

Edit: If you want to have something which looks more like an Android button you are going to want to create a gradient and set it as the background. For an example of this, you can check out this question.
