How to Set the Text Color of TextView in Code

Have you ever wondered how to change the text color of a TextView in your Android app using code instead of XML? 🤔 You're not alone! Many developers have faced this challenge and struggled to find a straightforward solution. But fear not! In this blog post, we'll dive into the common issues and provide easy-to-implement solutions. Let's get started! 🚀

The Problem:

By default, in XML, you can easily set the text color of a TextView using the textColor attribute. For example, android:textColor="#FF0000" would set the text color to red. But how do we achieve the same result in code? 🤷‍♂️

Attempting a Solution:

One might think that setting the text color in code is as simple as calling setTextColor() on the TextView object, passing in a color value. For instance:

holder.text.setTextColor(R.color.Red);

In this example, holder is a class that holds the TextView, and text is the TextView object we want to modify. We might assume that R.color.Red refers to the RGB value (#FF0000) defined in the strings resource file. But unfortunately, this approach doesn't yield the expected results.

The Int Parameter:

According to the documentation, the setTextColor() method requires an integer parameter. But what exactly should we pass into this method? 🤔

The parameter should be an integer representation of the color value you want to set. However, directly passing in R.color.Red won't work because R.color.Red is actually an integer resource ID, not the color value itself. So how do we obtain the correct integer representation of our desired color?

Solution: Resource.getColor()

To get the correct integer representation of a color resource, Android provides the getColor() method. This method retrieves the actual color value associated with a given resource ID. Here's how you can use it:

int color = holder.text.getContext().getResources().getColor(R.color.Red);
holder.text.setTextColor(color);

In this snippet, we first obtain the color value from the R.color.Red resource ID using getColor(). Next, we pass the obtained color value to setTextColor() to set the text color of our TextView.

And voila! 🎉 This solution ensures that you can modify the text color in code just as easily as you would in XML.
