How to create and apply styles through programming in android?

Question

Hi Friends,

I am new to Android app. development. I need to change the existing style at runtime or can create new styles at runtime and I need to apply it for my buttons and textviews..

Can any one suggest me?

Answer 1

There are several methods to do so (most of them are provided by the super class TextView):

• setTextColor to change the color of foreground
• setTypeface to change the font style
• setBackgroundResource(int) to change its backgrond
• setPadding to add padding

All of them work for EditText, Button and others, since most of them extends the TextView class. So, my suggestion is: RTFM... just kidding... read the documentation to see the available functions.

Hey,

That things I know. But, I want to apply the styles not individual items like android:style attribute.

Can I update the styles.xml to change the styles and apply that styles at run time?
