title: Android get data from another class
body: <p>I've tried to solve this before in another post but was unsuccessful. This is what I want to accomplish: When the user clicks the gpsbtn it will pull from the gps.printLocation method to get the long / lat. I want to auto populate the edittext but I think I could figure out how to do that with a quick google search. So if I could just store it the coords to a variable that would be all I want but my brain is not working. Full code:</p>
  
  <pre><code>public class Location extends Activity {
  
      /** Called when the activity is first created. */
      @Override
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
  
          // Full Screen
          requestWindowFeature(Window.FEATURE_NO_TITLE);
          getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                  WindowManager.LayoutParams.FLAG_FULLSCREEN);
  
          setContentView(R.layout.location);
  
          // Go button
          Button gobtn = (Button) findViewById(R.id.gobtn);
          final EditText Zipcodeinput = (EditText) findViewById(R.id.Zipcode);
          gobtn.setOnClickListener(new View.OnClickListener() {
  
              public void onClick(View view) {
                  // Edit text validation field
                  Pattern pattern = Pattern.compile("[0-9][0-9][0-9][0-9][0-9]"); // string needs 5 digits
                  // argument to matcher is string to validate
                  Matcher matcher = pattern.matcher(Zipcodeinput.getText()
                          .toString());
                  if (!matcher.matches()) // on Success
                  {
                      // invalid
                      // pop up ERROR message
                      Toast.makeText(getBaseContext(), " Invalid Input ",
                              Toast.LENGTH_LONG).show();
  
                  } else {
                      // validation successful
                      // Change to Listings Page
                      Intent filterIntent = new Intent(view.getContext(),
                              Listings.class);
                      startActivityForResult(filterIntent, 0);
                  }
              }
          });
  
          // button to get to list view
          Button gpsbtn = (Button) findViewById(R.id.gps); // temp use of gps
                                                              // button
          gpsbtn.setOnClickListener(new View.OnClickListener() {
              public void onClick(View view) {
  
                  // Toast.makeText(getApplicationContext(), "Please wait...",
                  // Toast.LENGTH_LONG).show();
                  Intent gpsIntent = new Intent(view.getContext(), gps.class);
                  startActivityForResult(gpsIntent, 0);
  
              }
  
          });
  
      }
