in code alertdialog has not initialized yet gives nullpointer.initialize alertdialog through create() method of builder. like:
alertdialog alert = builder.create(); alert.show(); and have not used view here. in method parameter take 1 view activity , initialize view components through not through alert.
public void gamedialog(activity activity, view view) { textview tv = (textview) view.findviewbyid(r.id.message); } and pass parent layout holds textview through parameter.
