How to Access Primary Text Color In Kotlin Fragment?

3 minutes read

To access the primary text color in a Kotlin fragment, you can use the android.R.attr.textColorPrimary attribute from the theme of the fragment's context. You can access the primary text color using the following code snippet:


val primaryTextColor = TypedValue() requireContext().theme.resolveAttribute(android.R.attr.textColorPrimary, primaryTextColor, true) val primaryColor = ContextCompat.getColor(requireContext(), primaryTextColor.resourceId)


This code will retrieve the primary text color from the current theme of the fragment's context and store it in the primaryColor variable for further use.


What is the best practice for managing the primary text color in a Kotlin fragment?

The best practice for managing the primary text color in a Kotlin fragment is to follow the principle of separating concerns and utilizing resources efficiently. Here are some suggested best practices:

  1. Use resources: Define the primary text color in your colors resources file, such as colors.xml. This allows you to easily update the color across your app by changing it in one central location.
  2. Use Data Binding: Use data binding to bind the primary text color resource to the TextView or other UI elements in your fragment layout. This allows for a more declarative and efficient way of setting the color.
  3. Use themes: Utilize themes to define the primary text color for your app or individual fragments. This allows for consistent styling across your app and simplifies the management of colors.
  4. Avoid hardcoding: Do not hardcode the primary text color directly in your code. This makes it harder to maintain and customize the color in the future.
  5. Consider accessibility: Ensure that the primary text color chosen meets accessibility guidelines and is easy to read for all users.


By following these best practices, you can effectively manage the primary text color in your Kotlin fragment in a way that is maintainable, efficient, and accessible.


What is the primary color of the text in a Kotlin fragment by default?

The primary color of the text in a Kotlin fragment by default is black.


How to access the default primary text color in a Kotlin fragment?

In a Kotlin fragment, you can access the default primary text color by using the following code snippet:

1
2
3
4
val color = android.R.attr.textColorPrimary
val typedValue = TypedValue()
requireContext().theme.resolveAttribute(color, typedValue, true)
val primaryTextColor = typedValue.data


This code snippet retrieves the default primary text color attribute from the current theme and stores it in the primaryTextColor variable. You can then use this color value to set the text color of any UI elements in your fragment.


How to access the primary text color programmatically in a Kotlin fragment?

In order to access the primary text color programmatically in a Kotlin fragment, you can use the following code:

1
2
3
4
5
6
7
8
9
val typedValue = TypedValue()
val theme = requireContext().theme

theme.resolveAttribute(android.R.attr.textColorPrimary, typedValue, true)

val primaryTextColor = typedValue.data

// Now you can use the primary text color
textView.setTextColor(primaryTextColor)


In this code snippet, we first create a TypedValue object to store the resolved attribute value. We then get the theme of the fragment's context and use the resolveAttribute() method to retrieve the primary text color attribute (in this case, android.R.attr.textColorPrimary). Finally, we assign the resolved color to the primaryTextColor variable and use it to set the text color of a TextView (replace textView with your actual view reference).


This code will allow you to programmatically access the primary text color in your Kotlin fragment and use it as needed.
