Question

boolean buttonflag=false;
        Editbutton.setOnClickListener( new OnClickListener()
        { 


            @Override
            public void onClick( View v )
            {
               buttonflag=true;

             }
        }

error im getting is “Cannot refer to a non-final variable buttonflag inside an inner class defined in a different method” what i want to do is when i press the Editbutton i want the buttonflag to be true..Can any one explain the reason and a fix for this problem?

Answer 1

The error message is pretty straight forward. Since buttonflag is not final, you cannot access it in your OnClickListener anonymous class. Two possible solutions

1. Make buttonflag a field

2. Make it final. However, then you cannot modify it, and you have to choose the one-dimensional array approach resulting in

   final boolean[] buttonflag=new boolean[]{false};
   Editbutton.setOnClickListener( new OnClickListener(){ 
      @Override
      public void onClick( View v ){
        buttonflag[0]=true;
      }
   }
