ok! i moved the code to onCreateDialog
and even tough vg is null, it created the alert. but should vg be
null ?
but it crashed again !
here is code
protected Dialog onCreateDialog(int id) {
AlertDialog.Builder builder;
AlertDialog alertDialog = null;
Context mContext = getApplicationContext();
LayoutInflater inflater = (LayoutInflater)
mContext.getSystemService
(LAYOUT_INFLATER_SERVICE);
switch(id) {
case MY_DIALOG_ID:
ViewGroup vg = (ViewGroup)
findViewById(R.id.layout_root);
View layout = inflater.inflate(R.layout.mydialog,
vg);
builder = new AlertDialog.Builder(mContext);
builder.setView(layout);
alertDialog = builder.create();
break;
default:
alertDialog = null;
}
return alertDialog;
}
void CheckHighScore() {
showDialog(MY_DIALOG_ID);
}
