            intentMessage.putExtra("MESSAGE", "hello");
            intentMessage.putExtra("selected_refer", customerpopulationlist.get(position).getLetId());

            setResult(RESULT_OK, intentMessage);
            finish();

        }
    });

Answer 1

you must hold an reference to your activity that created the adapter then set result to that. the thing you are doing is setting the result of OnClickListener object !!

add an Activity object to your adapter constructor and save it in a local variable in adapter and call it act then call the setResult() of the activtiy like below:

view.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View arg0) {
        SharedPreferences prefernces = mContext.getSharedPreferences("MyKey111", Context.MODE_PRIVATE);
        SharedPreferences.Editor editor1 = prefernces.edit();
        editor1.putString("Custname",customerpopulationlist.get(position).getName());
        editor1.putString("let_id", customerpopulationlist.get(position).getLetId());
        editor1.commit();

        Intent intentMessage = new Intent();

        // put the message in Intent
        intentMessage.putExtra("MESSAGE", "hello");
        intentMessage.putExtra("selected_refer", customerpopulationlist.get(position).getLetId());

        //THESE TWO LINES NEED TO BE CHANGED
        act.setResult(RESULT_OK, intentMessage);
        act.finish();

    }
});
