问题描述

我有一个按钮和一个TextView一个ListView。如何设置onclicklistener为ListView里面的按钮？
code如下：

I have a listView having a button and a textView. How can I set onclicklistener for the button inside the listView? Code Given below:

ListView.xml：

ListView.xml:

ListView lv1 = (ListView)popupView.findViewById(R.id.listView1);
listviewAdapter adapter = new listviewAdapter(Order_page.this, alist);
lv1.setAdapter(adapter);

ListviewAdapter类如下：

ListviewAdapter Class is as follows:

public class listviewAdapter extends BaseAdapter {
public ArrayList<HashMap<String, String>> list;
Activity activity;

public listviewAdapter(Activity activity,
        ArrayList<HashMap<String, String>> list) {
    super();
    this.activity = activity;
    this.list = list;
}

@Override
public int getCount() {
    // TODO Auto-generated method stub
    return list.size();
}

@Override
public Object getItem(int position) {
    // TODO Auto-generated method stub
    return list.get(position);
}

@Override
public long getItemId(int position) {
    // TODO Auto-generated method stub
    return 0;
}

class ViewHolder {
    Button btn_fav, btn_plus, btn_minus;
    TextView item_name;
    TextView item_price;
    TextView item_total;
    EditText et_quantity;
}

@Override
public View getView(int position, View convertView, final ViewGroup parent) {
    // TODO Auto-generated method stub

    // TODO Auto-generated method stub
    ViewHolder holder;
    LayoutInflater inflater = activity.getLayoutInflater();

    if (convertView == null) {

        convertView = inflater.inflate(R.layout.order_list_texts, null);
        holder = new ViewHolder();

        holder.btn_fav = (Button) convertView.findViewById(R.id.fav_btn_orderlist);
        holder.btn_plus = (Button) convertView.findViewById(R.id.order_pg_plus);
        holder.btn_minus = (Button) convertView.findViewById(R.id.order_pg_minus);

        holder.item_name = (TextView) convertView.findViewById(R.id.item_name);
        holder.item_price = (TextView) convertView.findViewById(R.id.itm_price);
        holder.item_total = (TextView) convertView.findViewById(R.id.Item_total);
        holder.et_quantity = (EditText) convertView.findViewById(R.id.et_quantity_order_list);

        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }

    HashMap<String, String> map = list.get(position);
    holder.item_name.setText(map.get(ITEM_NAME_COLUMN));
    holder.item_price.setText(map.get(ITEM_PRICE_COLUMN));
    holder.item_total.setText(map.get(TOTAL_COLUMN));
    holder.et_quantity.setText(map.get(ITEM_QUANTITY_COLUMN));

    return convertView;
}

}

请帮忙设置按钮的onClick事件

Please help to set onClick event of the button

推荐答案

您只需要添加一个监听器与 myButton.setOnClickListener（mBuyButtonClickListener）
这将在 getView（）来完成你的ListView

You just have to add a listener with myButton.setOnClickListener(mBuyButtonClickListener) This will be done in getView() of you ListView

您可以通过了解按钮的位置 myListView.getPositionForView（myButton的）
下面的解决方案可以帮助您：

you can know position of the button by using myListView.getPositionForView(myButton) Below solution can help you:

private OnClickListener mBuyButtonClickListener = new OnClickListener() {
@Override
public void onClick(View v) {
    final int position = getListView().getPositionForView(v);
    if (position != ListView.INVALID_POSITION) {
        //DO THE STUFF YOU WANT TO DO WITH THE position
    }
}

};
