Why isn't my bundle getting passed?
- by NickTFried
I'm trying to pass a bundle of two values from a started class to my landnav app, but according to the debug nothing is getting passed, does anyone have any ideas why?
package edu.elon.cs.mobile;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
public class PointEntry extends Activity{
private Button calc;
private EditText longi;
private EditText lati;
private double longid;
private double latd;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.pointentry);
calc = (Button) findViewById(R.id.coorCalcButton);
calc.setOnClickListener(landNavButtonListener);
longi = (EditText) findViewById(R.id.longitudeedit);
lati = (EditText) findViewById(R.id.latitudeedit);
}
private void startLandNav() {
Intent intent = new Intent(this, LandNav.class);
startActivityForResult(intent, 0);
}
private OnClickListener landNavButtonListener = new OnClickListener() {
@Override
public void onClick(View arg0) {
Bundle bundle = new Bundle();
bundle.putDouble("longKey", longid);
bundle.putDouble("latKey", latd);
longid = Double.parseDouble(longi.getText().toString());
latd = Double.parseDouble(lati.getText().toString());
startLandNav();
}
};
}
This is the class that is suppose to take the second point
