How to set the text color of TextView in code?

Question

In XML, we can set a text color by the textColor attribute, like android:textColor="#FF0000". But how do I change it by coding?

I tried something like:

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

Where holder is just a class and text is of type TextView. Red is an RGB value (#FF0000) set in strings.

But it shows a different color rather than red. What kind of parameter can we pass in setTextColor()? In documentation, it says int, but is it a resource reference value or anything else?

Answer 1

In order to set color of a TextView, TextView.setTextColor(R.color.YOURCOLOR) is not enough!

It has to be used like this –

TextView myText = (TextView) findViewById(R.id.YoutTextViewID);

myText.setTextColor(getResources().getColor(R.color.YOURCOLOR);

OR

myText.setTextColor(Color.parseColor("#54D66A"));

Answer 2

I did this way: Create a XML file, called Colors in res/values folder.

My Colors.xml:

    <?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="vermelho_debito">#cc0000</color>
    <color name="azul_credito">#4c4cff</color>
    <color name="preto_bloqueado">#000000</color>
    <color name="verde_claro_fundo_lista">#CFDBC5</color>
    <color name="branco">#ffffff</color>
    <color name="amarelo_corrige">#cccc00</color>
    <color name="verde_confirma">#66b266</color>
</resources>

To get this colors from the xml file, I've used this code: valor it's a TextView, and ctx it's a Context object. I'm not using it from an Activity, but a BaseAdapter to a ListView. That's why I've used this Context Object.

valor.setTextColor(ctx.getResources().getColor(R.color.azul_credito));

Hope it helps.

You can use

holder.text.setTextColor(Color.rgb(200,0,0));

You can also specify what color you want with Transparency.

holder.text.setTextColor(Color.argb(0,200,0,0));

a for Alpha (Transparent) value r-red g-green b-blue

Answer 4

If you are in an adapter and still want to use a color defined in resources you can try the following approach:

holder.text.setTextColor(holder.text.getContext().getResources().getColor(R.color.myRed));

Answer 5

There are many different ways to set color on text view.

1. Add color value in studio res->values->colors.xml as

   <color name="color_purple">#800080</color>
   

   Now set the color in xml or actvity class as

   text.setTextColor(getResources().getColor(R.color.color_purple)
   

2. If you want to give color code directly use below Color.parseColor code

   textView.setTextColor(Color.parseColor("#ffffff"));   
   

3. You can also use RGB

   text.setTextColor(Color.rgb(200,0,0));
   

4. Use can also use direct hexcode for textView. You can also insert plain HEX, like so:

   text.setTextColor(0xAARRGGBB);
   

5. You can also use argb with alpha values.

      text.setTextColor(Color.argb(0,200,0,0));
   

   a for Alpha (Transparent) v.

6. And if you're using the Compat library you can do something like this

      text.setTextColor(ContextCompat.getColor(context, R.color.color_purple));
   

Answer 6

From API 23 onward, getResources().getColor() is deprecated.

Use this instead:

textView.setTextColor(ContextCompat.getColor(getApplicationContext(), R.color.color_black));
