changing text color in Android TextView

obj=”<color name or #rrggbb>” where rr , gg and bb are hexadecimal values of red, green and blue respectively. All colors should be inside the quotation marks. Otherwise it will lead to compiler error.

To create a textview in xml layout file is like this,

android:layout_width=”wrap_content”

android:layout_height=”wrap_content” which means, it will take the whole space of its parent. In Java code, you created an object for TextView . After that set its width and height by setWidth() and setHeight().

For example,

TextView textview=(TextView)findViewById(R.id.text);

textview.setWidth(200); //width of the Textview is 200 dp

textview.setHeight(100); //height of the Textview is 100 dp

TextView is a subclass of ViewGroup, so you can set layout parameters such as margin , padding , gravity or scrollbar style on it. You can find several methods in the TextView class reference that are used to modify these properties for this widget. Just try them out and see what happens!

public class MainActivity extends Activity {

TextView textview=(TextView)findViewById(R.id.text);

textview.setTypeface(Typeface.MONOSPACE); //sets typeface to Monospace for all letter in this TextView

<dimen name=”typeface_size”>20dp</dimen> <!– Text size –>

android:text=”Welcome to my world!”

Run your app and you will see that the text view changes its font with dimension specified in typefaceSize.

font_name : it actually referred to the font styles that are available in your current device. To access all fonts first you need to define font family in your xml file for example,

android:text=”Welcome to my world!”

font_name=”font name” specifies the custom font which not installed on phone (e.g Roboto). The name of your custom font file must be in quotes.

android:text=”Welcome to my world!”

Just define the name of your custom font file in this attribute. Android will try to load the font from the given url location. Please note that it can’t always find the font you are trying to use, so make sure you put it somewhere where it can be found. If you want to load a font from your phone you should put the full path in quotes.
