android - Bug in a code the buttons 这些按钮什么都不做

Question

我有一个问题，我不知道哪个是错误，当我按下添加照片按钮或发送按钮时根本没有发生，我没有收到任何错误，第一个按钮应该打开我的照片，第二个按钮应该发送到我提供代码的 fragment 中的 RecyclerView

抱歉我的英语不好用谷歌翻译

fragment

 public class PostCreateDialog  extends DialogFragment implements View.OnClickListener{

    private static final int RC_PHOTO_PICKER = 1;

尝试在单击按钮时显示任何 toast。如果出现 toast，则说明您的点击事件有效；如果未显示 toast，则说明您的按钮点击无效。
