            // TODO Auto-gener2ated method stub
            about.setImageResource(R.drawable.helps);
            Intent i=new Intent(getApplicationContext(),aboutActivity.class);
            startActivity(i);
            Toast.makeText(getApplicationContext(), "Enter all fields", Toast.LENGTH_SHORT).show();
            about.setImageResource(R.drawable.help);

Answer 1

use onResume() to restore image previous state:

 @Override  
    protected void onResume() {  
        about.setImageResource(R.drawable.imageView6);
        super.onResume();  
    }
