java - Creating a static method that builds a RadioButton returns a NullPointerExeption -

so have static method building radiobutton:

public static radiobutton createaradiobutton() {     radiobutton radiobutton = new radiobutton(null);     return radiobutton; } 

and have assignment statement:

radiobutton = createaradiobutton(); 

which gives me nullpointerexeption.

now how write static method create radiobutton perform good? doing wrong in here?

you can't pass in null context argument radiobutton. @ least need this:

public static radiobutton createaradiobutton(context context) {     radiobutton radiobutton = new radiobutton(context);     return radiobutton; }
