2 activities, get value

[Mathew Mintalm]

Hello, Im making my application, and i have problem, hope some one is gonna help me.

Let me describe problem:

I have 2 activities:

- first for main menu, containing one TextView and one Button
- second containing only one TextView

And whats my problem? In my second activity i can not receive value from textview from first activity (always error, stopped unexpected ...)

    	TextView resultField = (TextView) findViewById(R.id.resultField);
    	String s = resultField.getText().toString();
    	int a = Integer.parseInt(s);

Never works, i have been trying with singleton holder and getInstance() aswell, but always the same.

Thanks in advance for any help.

If you're sending something simple, like Strings or numbers, you can pass these as "extras" to the new Activity when you launch it.

// Code in first activity to launch the second -

TextView resultField = (TextView) findViewById(R.id.resultField);  
String s = resultField.getText().toString();  
int result = Integer.parseInt(s); 
Intent i = new Intent( this, SecondActivity.class );
// Now add a as Extra Data
i.putExtra("result", result);
// start the Activity
startActivity(i); 
//....
// Code in second activity to get the data passed in -
Bundle extras = getIntent().getExtras();
int result = extras.getInt("result");
