Android, change button style at runtime

I need to change button style from "contained" to "outlined" at runtime.
For now the only way I've found to create an outlined button is to set its style to ?attr/materialButtonOutlinedStyle.
Unfortunately I haven't found a way to change the style at runtime, is it possible?
Is there any way to get this effect?

As a view with text inside, it should have "setTextAppearance" function. It's not the ideal option but may help. Also can be useful to look on https://github.com/airbnb/paris.

Dynamic colours in an app

I have colors of text and button come dynamic form backend,
I need to change this color of text dynamically when change happens in backend all at time.
I could make it manual
textView.setTextColor(getResources().getColor(R.color.text_color));
Is there a way to change group of text color dynamically or must set every text color manually in code?
I searched for how to change theme colors dynamically at run time and i found this answer this answer.
But I also search again and I found this github
but it doesn't work on Android Marshmallow (6.0+) and it's use is discouraged! as he say.
Is there any lib or method to change the theme on runtime?

So far it's impossible and not viable because of themes are immutable.
GreenMatter becomes outdated so regretfully the answer of your question is No way.
More precisely, the color overriding at runtime is not working. There is no fix found at the moment. The future of this feature is uncertain.

Android using switchpreference to set color background

How can I change the color of the app I'm trying to develop.
I have used a switch statement under preferences menu, but do not know how I can code this, so that when the user clicks on the switch, the background color is changed across the whole app.
Does anyone have any idea of how this can be done?
Thanks

You can enable the user to change the theme using preferences. This will change the background color throughout the application in accordance with the choice. The following thread is talking about the same problem: How to change current Theme at runtime in Android. Hope this helps.

Android, change only clicked color of a button

I would like to change the default orange color that appears when someone press an Android button. I have done many searches but all I found was the use of selectors.
I understand the principle, but I don't want to modify the grey aspect of the normal button (not pressed). But using selectors force to define all characteristics of all aspects (pressed or not).
I don't know how to obtain the default aspect of buttons in the light theme, so can anyone tell me where I can find the original parameters of the light theme or at least give me another means to simply change the color of the button when clicked?

You can copy the Android's selector into your project, the one that Android sets it by default to buttons, and modify only the state when the button is pressed by just changing one single drawable.
You could find the file in \android-sdk\platforms\android-10\data\res\drawable\btn_default.xml

Sorry bro...........
i guess only selector will help you......
You must go with selector.....
and selector are reusable xmls you can use in all buttons.....:)
You can refer below link.

I tried to find a solution to this problem, but did not succeed.
Maybe this will help:
