Answer 1

// First activity
actvty_btn.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {               
        Intent i = new Intent(v.getContext(),SECONDACTIVITY.class);    
        startActivityForResult(i, STATIC_INTEGER_VALUE);
    }
});

/* This function gets the value from the other activity where we have passed a value on calling this activity */ 
public void activity_value() {
    Intent i = getIntent();
    Bundle extras=i.getExtras();
    if(extras !=null) {
        // This is necessary for the retrv_value
        rtrv_value = extras.getString("key");

        if(!(rtrv_value.isEmpty())) {
            // It displays if the retrieved value is not equal to zero
            myselection.setText("Your partner says = " + rtrv_value);
        }
    }
}


// Second activity
myBtn.setOnClickListener(new View.OnClickListener () {
    public void onClick(View v) {
        Intent intent = new Intent(v.getContext(), FIRSTACTIVITY.class);
        Bundle bundle = new Bundle();
        bundle.putString("key", txt1.getText().toString());
        // Here key is just the "Reference Name" and txt1 is the EditText value
        intent.putExtras(bundle);               
        startActivity(intent);
    }
});
