将字符串变量从recyclerview传递到片段

public interface OnItemClickListener {
    void onItemClick(String item);
}

private OnItemClickListener mListener;

public void setOnItemClickListener(OnItemClickListener listener) {
    mListener = listener;
}

itemView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        if (mListener != null) {
            mListener.onItemClick(item);
        }
    }
});

public class MyFragment extends Fragment implements OnItemClickListener {
    // ...

    @Override
    public void onItemClick(String item) {
        // 在这里处理传递的字符串变量
    }
}

MyAdapter adapter = new MyAdapter();
adapter.setOnItemClickListener(myFragment);
