How to pass data from recyclerview adapter to fragment

Question

如何将数据从recyclerview适配器传递到fragment.I已经检查了堆栈溢出中的链接，但无法获取正确的代码。

Answer 1

Most efficient and professional method

Using CallBacks to communicate between adapter and fragment:

In Adapter:

 private Callback mlistener;

   public Interface Callback extends EventListener{

     public void onPassData(int data);

           }

   public void setListener(Callback listener)
    {
    this.mlistener = listener;
    }

And then you can Call listener method from anywhere in adapter as:

    mlistener.onPassData(4);

Receive Call back in Fragment:

   adapter.setListener(new Callback) {
   @Override
   public void onPassData(int data)
    {

   //YOu will receive data here whenever you call onPassData

   }}

Answer 2

 public interface AdapterCallback{
    void onReponse(Object data);
 }

In Adapter Contructor

CustomAdapter(...., AdapterCallback mCallback){
....
}

Call in Adapter like:

mCallback.onResponse(data);

Creating instance of adapter:

CustomAdapter obj = new CustomAdapter(....,new AdapterCallback() {
    @Override
    public void onReponse(Object data) {

    }
});
