Android(安卓)adapter中调用activity中的方法

随手记录工作中的点滴,有时我们可能会在adapter中调用activity中的方法,办法很简单,话不多说直接上代码

public class DetectionAdapter extends RecyclerView.Adapter<DetectionAdapter.ViewHolder> {    //使用这个adapter的activity    private DetectionActivity context;    public DetectionAdapter(DetectionActivity context) {        this.context = context;    }    @Override    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {        View view = layoutInflater.inflate(R.layout.item_detection, parent, false);        return new ViewHolder(view);    }    @Override    public void onBindViewHolder(ViewHolder holder, final int position) {        holder.mButtonDelete.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                           //此处调用activity中的方法                     context.upData();            }        });        @Override public int getItemCount () {            return 0;        }        class ViewHolder extends RecyclerView.ViewHolder {            private final Button mButtonDelete;            public ViewHolder(View itemView) {                super(itemView);                mButtonDelete = ((Button) itemView.findViewById(R.id.btn_delect_viscera_detection));            }        }    }
