How to get value in edittext from a Radio Groups in Popup Activity?

Question

I am designing a registration form where I have one EditText field for Categories. This list of categories is opened as a radio group in separate Popup activity when we click in EditText field. It is working fine till popup. However, I am not able to get the value back in the EditText field after selecting the RadioButton in the Popup activity.

Activity.java

import android.app.Activity;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.DisplayMetrics;
import android.view.Gravity;
import android.view.View;
import android.view.WindowManager;
import android.widget.EditText;
import android.widget.RadioButton;
import android.widget.TextView;

import java.security.PublicKey;

public class Industry extends Activity {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate ( savedInstanceState );
        setContentView ( R.layout.activity_industry );

        DisplayMetrics dm = new DisplayMetrics ();
        getWindowManager ().getDefaultDisplay ().getMetrics ( dm );

        int width = dm.widthPixels;
        int height = dm.heightPixels;

        getWindow ().setLayout ( (int)(width*.9),(int)(height*.85) );

        WindowManager.LayoutParams params = getWindow ().getAttributes ();
        params.gravity = Gravity.CENTER;
        params.x = 0;
        params.y = -20;

        getWindow ().setAttributes ( params );



    }

}

You can simply try with using SharedPreference object.... save the data in your sharedpreference object on Radio Button Click and get data from sharedpreference where you want.

If you share the code I can help more.
