How to keep your clothes on and have fun with text!

Android TextView icon

You use the TextView class to display text to the user.

Although you can also edit the text displayed in text views, it’s best to use the TextView subclass, EditText to do that.

The TextView class has a number of attributes that you can use to make your text really stand out. We’ll show you a few to whet your appetite.

Read on to see how to:

  • Create and position a TextView in a RelativeLayout in code
  • Add shadows to your text
  • Rotate your text
  • How to use different font families to impress with your text

Throw your weight around

Android layout_weight attribute weight icon

Linear layouts support a layout_weight attribute.

We can use the weight attribute to allocate a portion of the layout’s space to a view, depending on its weight.

All views have a default weight of 0.

You can set a weight attribute using a float value for any view that you use in a LinearLayout. Android will then divide the available space up amongst the views proportionately, depending on their weight values.
