Question

我收到此错误：对于非静态字段，方法或属性'Android.App.FragmentManager.BeginTransaction（）'在行中需要对象引用：FragmentTransaction transaction = FragmentManager.BeginTransaction（）;

void mEditar_Click (object sender, EventArgs e )
            {
                FragmentTransaction transaction = FragmentManager.BeginTransaction();

                dialog_Editar_produto dialog_editar = new dialog_Editar_produto ();
                dialog_editar.Show (transaction, "dialog fragment");

                dialog_editar.mOnEditarComplete += dialog_editar_mOnEditarComplete;

            }

我该怎么办？

Answer 1

该错误消息表明BeginTransaction不是FragmentManager类的静态方法。尝试访问班级中的FragmentManager对象。

试试这个：

FragmentTransaction transaction = this.FragmentManager.BeginTransaction();

Answer 2

使用此代码：

FragmentManager fragmentManager = getFragmentManager()
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
