how to retrieve values from popup to main?

Question

I have a main Activity that calls a popup window:

AddProduct.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent popup = new Intent(SingleVoucher.this, PopUp.class);
                if (additionalProduct!=null) {
                    popup.putExtra("additionalamount", additionalQuantity);
                    popup.putExtra("additionalprice", additionalPrice);
                    popup.putExtra("additionalproduct", additionalProduct);
                }
                startActivity(popup);

            }
        });

the popup:

public class PopUp extends Activity {

private OnSubmitListener mListener;

@Override
protected void onCreate (Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.popup_window);
    DisplayMetrics dm = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(dm);
    int width = dm.widthPixels;
    int height = dm.heightPixels;
    WindowManager.LayoutParams windowManager = getWindow().getAttributes();
    windowManager.dimAmount = 0.75f;
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
    TextView SubmitAdditional = (TextView) findViewById(R.id.SubmitAdditional);
    final EditText product = (EditText) findViewById(R.id.adittionalTextEdit);
    final EditText qty = (EditText) findViewById(R.id.additionalQuantityTE);
    final EditText price = (EditText) findViewById(R.id.adittionalPriceTE);
    final Intent intent = getIntent();
    final Context context = this;
    SubmitAdditional.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String additionalProduct = product.getText().toString();
            String additionalQuantity = qty.getText().toString();
            String additionalPrice = price.getText().toString();
            if (additionalProduct!=null && additionalPrice.isEmpty()==false && additionalQuantity.isEmpty()==false) {
                intent.putExtra("additionalamount", additionalQuantity);
                intent.putExtra("additionalprice", additionalPrice);
                intent.putExtra("additionalproduct", additionalProduct);

            }
            else{
                AlertDialog.Builder alert = new AlertDialog.Builder(context);
                alert.setTitle("Missing Details");
                alert.setMessage("Some of the required fields are missing. please try again");
                alert.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener(){
                    @Override
                    public void onClick(DialogInterface dialog, int which) {

                    }
                });


            }

        }
    });
    getWindow().setLayout((int) (width * .8), (int) (height * .3));
}

}

and the XML of the poup window is:

I want to get the values from the EditText and send them back to the parent. How can I send the data back to the view who called the popup?

use intent to send data back to your activity.. – Mustanser Iqbal Feb 08 '16 at 07:36 — Mustanser Iqbal, Feb 08 '16 at 07:36

You will have to startActivityForResult()

then return result from PopUp Activity using setResult()

see this good link for statActivityForResult

You can use startActivityForResult and setResult methods to achieve this. In MainActivity start the popup activity like this

 startActivityForResult(popup,1);

In popup activity use the setResult method to pass the value back to main activity.

    Intent intent = new Intent();
    intent.putExtra("data",data); // data is the value you need in parent
    setResult(100,data);

In MainActivity use the onActivityResult method to get the data

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {     value = data.getBundleExtra("data");

Try to use startActivityForResult in order to show the popup.

Here is an example: http://developer.android.com/training/basics/intents/result.html

Then in the main activity you should override onActivityResult in order to have access to the info you sent from popup.

how to retrieve values from popup to main?
