Activity multiple

[annasvensson]

Hi,
I do not got this correct. I want to make two choices and write the choices in the main activity window.

The idea is to make the first choice (activity) and a new window pops up. Make the second choice (activity) and the total results, first and second activity print out in the main window.
Can you pls help me? 

MainActivity.java file
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
private final int WHISKY_ID = 1;
private final int DAYS_ID = 2;
@override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void chooseDay(View caller)
{
String instruction = "Please select your whisky-weekday from the list below:";
String buttonText = "OK";
String[] array = { "Monday", "Tuesday", "Wednesday", "Thursday", "Friday" };
Intent intent = new Intent(this, com.goran.dayandwhisky.ChooserActivity.class);
intent.putExtra(ChooserActivity.PARAM_INSTRUCTION, instruction);
intent.putExtra(ChooserActivity.PARAM_CHOICES, array);
intent.putExtra(ChooserActivity.PARAM_BTN_TEXT, buttonText);
startActivityForResult(intent, DAYS_ID);
}
public void chooseWhisky(View caller)
{
String instruction = "Please select your favourite whisky from the list below:";
String buttonText = "Done";
String[] array = { "Lagavulin", "Laphroaig", "Caol Ila", "Ardbeg", "Bowmore" };
Intent intent = new Intent(this, com.goran.dayandwhisky.ChooserActivity.class);
intent.putExtra(ChooserActivity.PARAM_INSTRUCTION, instruction);
intent.putExtra(ChooserActivity.PARAM_CHOICES, array);
intent.putExtra(ChooserActivity.PARAM_BTN_TEXT, buttonText);
startActivityForResult(intent, WHISKY_ID);
}
public void quit(View caller)
{
finish();
}
@override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK)
{
String result = data.getStringExtra(ChooserActivity.RETURN_VALUE);
TextView textView = null;
if(requestCode==DAYS_ID)
textView = this.findViewById(R.id.textView1);
else if(requestCode==WHISKY_ID)
textView = this.findViewById(R.id.textView2);
if (textView != null)
textView.setText(result);
}
}
}

spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener(){
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id){

}
public void onNothingSelected(AdapterView<?> parent) {}
});
}
public void quit(View caller)
{
Intent returnIntent = new Intent();
returnIntent.putExtra(RETURN_VALUE, selectedString);
setResult(RESULT_OK, returnIntent);
finish();
}
}
