為什么除了監聽器綁定會提示程序包不存在，找不到符號，別的都行呢，語法應該沒錯，我貼下代碼
public?void??OnClickListenerBinding(User?user){
????Toast.makeText(MainActivity.this,user.getLastName(),Toast.LENGTH_SHORT).show();
}<TextView
????android:onClick="@{()?->?presenter.OnClickListenerBinding(user)}"
????android:text="@{User.lastName}"
????android:layout_width="wrap_content"
????android:layout_height="wrap_content"?/>只有綁定監聽器事件不行，別的都可以的，這是什么原因，語法檢查很多遍沒錯啊
