Android setBackgroundTintList on pre-lollipop devices

Question

I'm working with FloatingActionButton. The user should be able to switch the FAB background color within a onClick Event.

However, the recommended call to setBackgroundTintList seems to be only compatible from 21+ API.

How do I - correctly - go about it on pre-lollipop devices? Is there any alternative I could use?

Thanks in advance.

@Skizo Thank you! Wasn't aware of that ViewCompat call (neither of the setSupportBackgroundTintList). Please write your own answer so that I can mark it as accepted! — Lampione, Nov 10 '15 at 22:04

You can use also setSupportBackgroundTintList

Applies a tint to the background drawable. Does not modify the current tint mode, which is SRC_IN by default.

Subsequent calls to View.setBackground(Drawable) will automatically mutate the drawable and apply the specified tint and tint mode.

Also take a look on ViewCompat.setBackgroundTintList()

Applies a tint to the background drawable.

This will always take effect when running on API v21 or newer. When running on platforms previous to API v21, it will only take effect if view implement the TintableBackgroundView interface.

I found a solution here on SO that I've used before and is this:

public static void setButtonTint(Button button, ColorStateList tint) {
  if (Build.VERSION.SDK_INT == Build.VERSION_CODES.LOLLIPOP && button instanceof AppCompatButton) {
      ((AppCompatButton) button).setSupportBackgroundTintList(tint);
  } else {
      ViewCompat.setBackgroundTintList(button, tint);
  }
}

It works for me I hope it works for you too.

But FloatingActionButton does not implement TintableBackgroundView, so the ViewCompat.setBackgroundTintList() does not work for API < 21 – lage May 31 '16 at 08:22

I get a lint warning when using AppCompatButton.setBackgroundTintList() AppCompatButton.setSupportBackgroundTintList can only be called from within the same library group (groupId=com.android.support) – starkej2 Apr 19 '17 at 18:11
@starkej2 may you post a question with images related with your issue and link here your question link? I'll try to help you :D – Skizo-ozᴉʞS ツ Apr 19 '17 at 20:34
@Skizo-ozᴉʞS I think all you need to do is call ViewCompat.setBackgroundTintList(button, tint) regardless of API level – starkej2 Apr 20 '17 at 14:03
ViewCompat.setBackgroundTintList(button, tint); is working for my AppCompatButton button's on API 19/Kit Kat. This answer's IF should really be checking for Lollipop and below. – Alan Jun 03 '17 at 20:41

simple:

fab.setBackgroundTintList(ColorStateList.valueOf(0xFF4CAF50));

fab is your FloatingActionButton of course and 0xFF4CAF50 just a example color

I think you didn't understand what I meant. Check @Skizo answer for further clarification. Thank you by the way! :) – Lampione Nov 10 '15 at 22:14
is this way backward compatible – Basheer AL-MOMANI May 10 '16 at 06:32

@Matteo FAB implementation comes from support lib and it does support backward compatibility. Underneath `setBackgroundTintList()` is using different impl for pre-lolipop. Proven on KitKat device. – Kamil Seweryn Feb 24 '17 at 12:19

From XML, you can use

card_view:backgroundTint="@color/your_color"

where card_view is xmlns:card_view="http://schemas.android.com/apk/res-auto"
