I created an Android application with two activities, but somehow the buttons on the second activity do not seem to work properly. The button on the first activity (a map activity and a button to add infromat which takes users to the second activity with an information entry screen) works fine, neither button on the second activity seems to have any effect... I can't even get an OnClick Toast message to work.
public class MapsActivity extends FragmentActivity implements OnMapReadyCallback , LocationListener {
public void AddMapInfo(View view) {
Intent intent = new Intent(this, InformationInputActivity.class);
LatLng providedLocation = current;
Bundle args = new Bundle();
args.putParcelable("provided_location", providedLocation);
intent.putExtra("bundle", args);
startActivityForResult(intent, 1);
}
public void onActivityResult (int requestCode, int resultCode, Intent data){
Toast.makeText(this, "back with cheese!", Toast.LENGTH_LONG).show();
if (requestCode != 1){
Toast.makeText(this, "Oops... This shouldn't happen", Toast.LENGTH_LONG).show();
}
else{
setContentView(R.layout.activity_maps);
InformationPoint informationPoint = (InformationPoint) data.getSerializableExtra("information_point");
informationPoint.display(mymap);
}
}
}
The second activity brings on the layout for the screen, and it sets the proper options for the EditText field, so I know it gets control... but that's about it. There is no Toast message from any of the methods (I still get the Toasts when the location update info is received on the first activity instead), and neither the radio button or submit buttons seem to work, I'm also not getting the result and control back in the first activity. (Previously, I used to be able to get a Toast on ever on checked option on the radio button, but now that doesn't seem to work either). Trying to send the activity result aborts the application (since I added finish() to the second activity).

I didn't see any problem but missing invocation of show() after toast creation, just like this:
Toast.makeText(this, "Oops... This shouldn't happen", Toast.LENGTH_LONG).show();
