I have an onTouch method that creates a new GeoPoint where the user
touches the screen. It then opens a dialog box and asks them for a
name for this GeoPoint. This method is shown below:
@Override
public boolean onTouchEvent(MotionEvent event, MapView mapView) {
if(event.getAction() == MotionEvent.ACTION_DOWN) {
if (add == true) {
this.add = false;
this.p = proj.fromPixels((int)event.getX(),
(int)event.getY());
LayoutInflater li = LayoutInflater.from(mContext);
View view = li.inflate(R.layout.adddialog, null);
winAlert = new AlertDialog.Builder(mContext)
.setIcon(R.drawable.marker)
.setTitle("Add a new POI")
.setPositiveButton("Save", mOnClickListener)
.setNegativeButton("Cancel", mOnClickListener)
.setView(view);
winDialog = winAlert.create();
winDialog.show();
}
}
return false;
}
Now when the Save button is clicked, this method is called to add the
point:
OnClickListener mOnClickListener = new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
switch(which) {
case -1:
add_dialog_editText = (EditText)
winDialog.findViewById
(R.id.add_dialog_editText);
addLocation(p, "Test",
add_dialog_editText.getText().toString());
break;
case -2:
dialog.cancel();
return;
}
}
};
My add location method looks like this:
public void addLocation(GeoPoint p, String title, String desc) {
OverlayItem overlayItem = new OverlayItem(p, title, desc);
this.addOverlay(overlayItem);
mapOverlays.add(this);
}
Now my issue is that my points will not display on the map unless
1) I add an initial point in the constructor of this class
2) Even after I add an initial point in the constructor, the points
don't show up until I touch the screen once more (anywhere).
I find if I comment out the dialog and put a static description the
points show up immediately so there must be something in the Dialog
that doesn't update until the user clicks the screen after the dialog
has been closed? I really don't understand why this is behaving like
this, can someone give me some help?
