Question

This is probably quite basic but I’ve only needed a use for a feature like this now. I have a button that carries out a calculation when I click on it. The output is a number. I want to put that number into a TextView on a different layout. On it’s own page basically.

I can already get what I want on the same page. Just do the whole

TextView.setText(); 

Can anyone help me put the data onto it’s own page? So when I click the button it carries out the calculation AND opens this new page to put the answer on it?

I tried putting the TextView in a new layout file and calling it via a findViewById but that gave me a force close.

Any solutions? Thanks.

EDIT: Here’s the code, I’m trying to display the time on another page. See below

public void getWakeUpTime (View v) {

    LocalTime localtime = new LocalTime();
    LocalTime dt = new LocalTime(localtime.getHourOfDay(), localtime.getMinuteOfHour());
    LocalTime twoHoursLater = dt.plusHours(2);

    DateTimeFormatter formatter = DateTimeFormat.forPattern("HH:mm");
    Text1.setText("Time: " + twoHoursLater.toString(formatter));

}

Right now it displays on the same page under the TextView Text1.

You can pass integer to next activity using this code:

String num;
Intent i = new Intent(this, NextActivity.class);
i.putExtra("value", num);
startActivity(i);

You can retrieve the data on next activity as shown below:

Intent i = getIntent();
String num = i.getStringExtra("value");
textview.setText("Number is: "+num);
