How to set the text color of TextView in code?
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?
Solution 1:
You should use:
holder.text.setTextColor(Color.RED);
You can use various functions from the Color
class to get the same effect of course.
-
Color.parseColor
(Manual) (like LEX uses)text.setTextColor(Color.parseColor("#FFFFFF"));
-
Color.rgb
andColor.argb
(Manual rgb) (Manual argb) (like Ganapathy uses)holder.text.setTextColor(Color.rgb(200,0,0)); holder.text.setTextColor(Color.argb(0,200,0,0));
-
And of course, if you want to define your color in an
XML
file, you can do this:<color name="errorColor">#f00</color>
because the
getColor()
function is deprecated1, you need to use it like so:ContextCompat.getColor(context, R.color.your_color);
-
You can also insert plain HEX, like so:
myTextView.setTextColor(0xAARRGGBB);
Where you have an alpha-channel first, then the color value.
Check out the complete manual of course, public class Color extends Object.
1This code used to be in here as well:
textView.setTextColor(getResources().getColor(R.color.errorColor));
This method is now deprecated in Android M. You can however use it from the contextCompat in the support library, as the example now shows.
Solution 2:
If you still want to specify your colors in your XML file:
<color name="errorColor">#f00</color>
Then reference it in your code with one of these two methods:
textView.setTextColor(getResources().getColor(R.color.errorColor, getResources().newTheme()));
or
textView.setTextColor(getResources().getColor(R.color.errorColor, null));
The first is probably preferable if you're compiling against Android M, however the theme you pass in can be null, so maybe that's easier for you?
And if you're using the Compat library you can do something like this
textView.setTextColor(ContextCompat.getColor(context, R.color.errorColor));
Solution 3:
And another one:
TextView text = (TextView) findViewById(R.id.text);
text.setTextColor(Color.parseColor("#FFFFFF"));
Solution 4:
You can do this only from an XML file too.
Create a color.xml
file in the values folder:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="textbody">#ffcc33</color>
</resources>
Then in any XML file, you can set color for text using,
android:textColor="@color/textbody"
Or you can use this color in a Java file:
final TextView tvchange12 = (TextView) findViewById(R.id.textView2);
//Set color for textbody from color.xml file
tvchange1.setTextColor(getResources().getColor(R.color.textbody));
