更改 strings.xml 中 TextView 一部分的颜色

Question

In my android app with Kotlin, I created a layout in which there's a TextView that shows some text. For the text I have an item in strings.xml where I want to change the color of part of this Text, I tried the following code :

<string name="description">the product is <font fgcolor="green"> free </font></string>

But, The color didn't change. I just want to change the color of "free" to green, can someone explain how I can achieve this?

Answer 1

Use <font color="#008000">free</font> instead. According to the documentation , the correct attribute name is color and it only supports hex codes.

Answer 2

Ben P. 's awesome answer should satisfy your use case. However, I want to present to you another way you can achieve this.

You can use SpannableString to achieve the same effect. With SpannableString, you can set several behaviours (color, font-weight, font-size, click-behaviour, etc) to any part of your String.

For the string in your question, you can do something like this:

// the textview you want to set your coloured text to
TextView textView = (TextView) findViewById(R.id.myTextView);

// declare the string you want to span as a Spannable
Spannable wordtoSpan = new SpannableString("the product is free");  

// set the colour span        
wordtoSpan.setSpan(new ForegroundColorSpan(Color.GREEN), 15, 19, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

// set the text to your TextView
textView.setText(wordtoSpan);
