我试图显示从手机到回收视图的所有联系人,当用户按下任何项目时,它应该做一些工作。当我单击

onClicklistener
未执行时,我在片段页面适配器内的片段中有一个联系人列表

我所做的是在您的RecyclerView适配器中创建一个接口:

public interface OnClickItem { // create an interface
    void onClickItem(int position); // create callback function
}
然后在OnBindViewHolder中:

customViewHolder.(yourView).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
               ContactListener.onClickItem(customViewHolder.getAdapterPosition());
            }
});
public class ListOfContacts extends Fragment implements ListOfContactsRAdapter.OnClickItem { ...
@Override
  public void onClickItem(int position) {
  ... 
  }
在你的片段中

customViewHolder.(yourView).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
               ContactListener.onClickItem(customViewHolder.getAdapterPosition());
            }
});
public class ListOfContacts extends Fragment implements ListOfContactsRAdapter.OnClickItem { ...
@Override
  public void onClickItem(int position) {
  ... 
  }
实施方法

customViewHolder.(yourView).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
               ContactListener.onClickItem(customViewHolder.getAdapterPosition());
            }
});
public class ListOfContacts extends Fragment implements ListOfContactsRAdapter.OnClickItem { ...
@Override
  public void onClickItem(int position) {
  ... 
  }

我已经使用了这个代码没有任何工程…我的完整项目源代码好的,我会让你知道,如果我可以修复这个。
