I'm looking for a solution to create a theme style dynamically in an android app. Our customer make there styles in an back office and from the application we retrieve this information. With this info's we wan't to update the current theme or create a new one. But we didn't found a way to do this because we can't add or change a data in sytle.xml or R class during running app.
I don't want to modify element by element on loading page in code like this textViewStyleDynamic.setTextColor(Color.BLUE).
It would be perfect to edit or create a theme dynamically and set it on the app.

I have a android custom view that start a custom action view when long clicked, as such, it require the theme of the activity to have the style "windowActionModeOverlay" set to true. I don't want to define a custom theme. I want to use whatever theme the user provided for the activity, and set the style to true at runtime using code myself.
Is this possible ?
Please note any suggestion by changing style xml file is not what I am looking for, unless it allow user to use whatever theme they choose for their activity.
Thanks
There are tons of solution for changing the style of a single view. There are tons of solution for changing theme at runtime, but I only want to change a single style of a theme, and so far, I can not find a solution myself or online
I'm building a material design playground that can switch between the available pre-defined themes that can apply the color, typography and shapes to all the material design components throughout the app.
Right now, the user can choose available themes from the PreferenceScreen:
I got a NEW requirement that should allow the user to enter a value (eg. set color of colorPrimary). From the input, I would like to modify the Theme directly so that it could apply the change in the app.
How can I do this? I'm thinking of giving an option to the user something like below:
Here's a link to my sample material design playground app:

Seems like you need something like this android-how-to-change-application-theme-programmatically
link: android-how-to-change-application-theme-programmatically
This should be easy and there are lot of tutorials out there, don't forget to checkout
Basically what you need to do is:
apply statically defined theme(in res/values) as usual before activity is launched.
Now get the user input when activity is launched
Then get the current theme attributes using appropriate api and recolourize the ui controls dynamically in the program.
restart activity with the updated theme.
Some more link: Set theme color dynamically
You should be comfortable handling the activity lifecycle to view the updated theme when set.
I have a requirement to display a theme that comes from a webservice (return the color etc). What I want to know is can I create a style programmatically? I have my code setup to incorporate theme and I have 2 themes defined in xml which work perfectly fine. And now I want to add a third theme which is not locally in an xml. Is this even possible?
The other approach to achieve this is to create custom classes for views and apply the style according to the theme. Which is I don't want to do, as it is very tedious and error prone.
Any other suggestions are welcomed as well.
A similar question to this has been asked many times; however, an answer has not been given that addresses my situation. I need to dynamically change an application's theme based on color values that are being returned from an API call. I then need to change the theme colors of the app based on the values returned. Therefore, I have no way of saving the colors in a style XML file. Can this be done?
I have a base activity, and my plan is to set the app theme from there for all the activities.
Unfortunately, I did not find an easy way to do this. I created a ThemeColor class which holds all the colors returned by the API. Then for each activity I have to go through every widget and style it.
Example:
getActionBar().setBackgroundDrawable(new ColorDrawable(Color.parseColor(themeColor.getActionBarColor)));
this.getWindow().getDecorView().setBackgroundColor(Color.parseColor(themeColor.getBackgroundColor()));
etc
I was not able to locate a simple way to resolve this issue either. By creating a ThemeColor class that holds all the colors returned from the API. Next for each activity I needed to address each widget separately as well as style it.
I want to produce a single app that would let the user select a theme and have this applied over the entire app.
I understand that this can be achieved by using setTheme in onCreate of each activity.
But I need this to work in a different way. I don't want to have the themes stored in theme.xml or styles.xml.
I want to have a list of themes stored on the web and be able to dynamically download a new theme and have it applied in the app. I want to be able to create new themes without having to build a new version or an updated version of the app.
Images would be easy to replace. Just download from a url and store locally to be re-used. But the actual theme of the app, the colours of buttons etc should be changed at run time from a theme.xml file which isn't part of the apk but is fetched online.
Is this possible?
It depends how much styling you want to be able to do. You currently can't set view items styles grammatically outside of using a resource. But you can control things like text color and background color. If that's all you need to change, I would recommend writing a Theme factory class for you app that you use to get each view element you need. For example a getButton() function that will return you a button with the background color and text color you need.
