RecycleView多控件携带多个参数点击事件

ListView多控件点击与此类似

在res-values-string.xml里定义常量

<!--设置多个tag-->
<item name="position" type="id" />
<item name="contact" type="id" />

定义回调接口

/**
 * 多个控件点击
 * Created by wulsh on 2017/8/30.
 */

public interface MultiWidgetClick {

    void onTextClick(int position, String content);

    void onButtonClick(int position, String content);
}

Adapter

public class FruitAdapter extends RecyclerView.Adapter<FruitAdapter.ViewHolder> implements View.OnClickListener {

    private ArrayList<Fruit> fruits;
    private MultiWidgetClick multiWidgetClick;


    public FruitAdapter(ArrayList<Fruit> fruits) {
        this.fruits = fruits;
    }

    public void setMultiWidgetClick(MultiWidgetClick multiWidgetClick) {
        this.multiWidgetClick = multiWidgetClick;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.item_recycle, parent, false);
        ViewHolder holder = new ViewHolder(view);
        return holder;
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        Fruit fruit = fruits.get(position);
        holder.txt_name.setText(fruit.getName());
        holder.btn_age.setText(fruit.getAge());
        holder.txt_name.setOnClickListener(this);
        holder.btn_age.setOnClickListener(this);
        holder.txt_name.setTag(R.id.position, position);
        holder.txt_name.setTag(R.id.contact, fruit.getName());
        holder.btn_age.setTag(R.id.position, position);
        holder.btn_age.setTag(R.id.contact, fruit.getName());
    }

    @Override
    public int getItemCount() {
        return fruits.size();
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.txt_name:
                if (multiWidgetClick != null) {
                    multiWidgetClick.onTextClick((int) v.getTag(R.id.position),
                            (String) v.getTag(R.id.contact));
                }
                break;
            case R.id.btn_age:
                if (multiWidgetClick != null) {
                    multiWidgetClick.onButtonClick((int) v.getTag(R.id.position),
                            (String) v.getTag(R.id.contact));
                }
                break;
        }
    }

    static class ViewHolder extends RecyclerView.ViewHolder {
        TextView txt_name;
        Button btn_age;

        public ViewHolder(View itemView) {
            super(itemView);
            txt_name = (TextView) itemView.findViewById(R.id.txt_name);
            btn_age = (Button) itemView.findViewById(R.id.btn_age);
        }
    }
}

Activity使用

LinearLayoutManager manager = new LinearLayoutManager(this);
        recycle_view.setLayoutManager(manager);

adapter = new FruitAdapter(fruits);
        recycle_view.setAdapter(adapter);

adapter.setMultiWidgetClick(new MultiWidgetClick() {
            @Override
            public void onTextClick(int position, String content) {
                //Log.d("CMCC", "点击了文字:" + position + ",content:" + content);
                Toast.makeText(MainActivity.this, "点击了文字:" + content, Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onButtonClick(int position, String content) {
                //Log.d("CMCC", "点击了按钮:" + position + ",content:" + content);
                Toast.makeText(MainActivity.this, "点击了按钮:" + position, Toast.LENGTH_SHORT).show();
            }
        });
