问题描述
我使用自定义适配器，以显示我的ArrayList的项目。每一行项目有2 textViews和图像按钮。根据一个属性的状态，在图像按钮图像是变化的。虽然这看起来很容易，我无法找到一种方式来获得来自行项目（订单ID在我的情况）的一些信息，点击图像按钮时。这是我的自定义适配器类
公共类OrderedAdapter扩展ArrayAdapter＆LT; RMOrder＆GT; {
私人上下文的背景下;
私人RMOrder rowItem;
私人的ListView LV;
私人诠释clickedID;
私人的ArrayList＆LT; RMOrder＆GT;项目;
私人诠释订单ID;
私人ViewHolder持有人;
公共OrderedAdapter（上下文的背景下，INT textViewResourceId，名单，其中，RMOrder＆GT;对象）{
超（背景下，textViewResourceId，对象）;
this.context =背景;
}
/ *私有视图holder类* /
私有类ViewHolder {

}
公共查看getView（最终诠释的立场，观点convertView，ViewGroup中父）{
支架=无效;
rowItem =的getItem（位置）;
LayoutInflater mInflater =（LayoutInflater）context.getSystemService（Activity.LAYOUT_INFLATER_SERVICE）;
如果（convertView == NULL）{
convertView = mInflater.inflate（R.layout.basket_list_row，NULL）;
持有人=新ViewHolder（）;
holder.txtMenuName =（TextView中）convertView.findViewById（R.id.menuNameText）;
holder.txtMenuDesc =（TextView中）convertView.findViewById（R.id.menuDetailText）;
holder.deleteButton =（的ImageButton）convertView.findViewById（R.id.menuDelete）;
holder.txtMenuPrice =（TextView中）convertView.findViewById（R.id.menuPrice）;
holder.orderID = 0;
LV =（ListView控件）convertView.findViewById（R.id.orderedList）;
convertView.setTag（保持器）;
} 其他
支架=（ViewHolder）convertView.getTag（）;
字符串detailsString =;
双价= rowItem.getPrice（）;
为（RMOption I：rowItem.getOption（））{
detailsString + = - + i.getName（）;
价格+ = i.getExtraPrice（）;
}
holder.orderID = rowItem.getId（）;
holder.txtMenuName.setText（rowItem.getMenuName（））;
holder.txtMenuDesc.setText（detailsString）;
holder.txtMenuPrice.setText（Double.toString（价格）+TL）;
holder.deleteButton.setFocusable（假）;
项=新的ArrayList＆其中; RMOrder＆GT;（GlobalList.orderedItemsList.values（））;
clickedID = items.get（位置）.getId（）;
订单ID = holder.orderID;
//改变图像按钮的图像
如果（rowItem.getStatus（）。等于（悬而未决））{
holder.deleteButton.setImageResource（R.drawable.rsz_pending）;
holder.deleteButton.setOnClickListener（新OnClickListener（）{
// TODO Buradatıklananıbulmaktasıkıntı变种
公共无效的onClick（视图v）{
//获取订单ID
}
}）;
其他
holder.deleteButton.setImageResource（R.drawable.rsz_approved）;
}
返回convertView;
}
解决方案
设置位置deleteButton标签
holder.deleteButton =（的ImageButton）convertView.findViewById（R.id.menuDelete）;
holder.deleteButton.setTag（位置）;
然后的onClick
holder.deleteButton.setOnClickListener（新OnClickListener（）{
// TODO Buradatıklananıbulmaktasıkıntı变种
公共无效的onClick（视图v）{
INT POS = Integer.parseInteger（v.getTag（））;
RMOrder rItem =的getItem（POS）;
INT的orderId = rowItem.getId（）;
}
}）;
I am using custom adapter to show the items in my ArrayList. Each row item has 2 textViews and an image button. Depending on the status of an attribute, image on the image button is changing. Although it seems quite easy, I couldn't find a way to get some information from row item(orderID in my case), when image button is clicked. This is my custom adapter class
public class OrderedAdapter extends ArrayAdapter<RMOrder> {
private Context context;
private RMOrder rowItem;
private ListView lv;
private int clickedID;
private ArrayList<RMOrder>items;
private int orderID;
private ViewHolder holder;
public OrderedAdapter(Context context, int textViewResourceId, List<RMOrder> objects) {
super(context, textViewResourceId, objects);
this.context = context;
}
/*private view holder class*/
private class ViewHolder {
ImageButton deleteButton;
TextView txtMenuName;
TextView txtMenuDesc;
TextView txtMenuPrice;
int orderID;
}
public View getView(final int position, View convertView, ViewGroup parent) {
holder = null;
rowItem = getItem(position);
LayoutInflater mInflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
convertView = mInflater.inflate(R.layout.basket_list_row, null);
holder = new ViewHolder();
holder.txtMenuName = (TextView) convertView.findViewById(R.id.menuNameText);
holder.txtMenuDesc = (TextView) convertView.findViewById(R.id.menuDetailText);
holder.deleteButton = (ImageButton) convertView.findViewById(R.id.menuDelete);
holder.txtMenuPrice = (TextView) convertView.findViewById(R.id.menuPrice);
holder.orderID = 0;
lv = (ListView) convertView.findViewById(R.id.orderedList);
convertView.setTag(holder);
} else
holder = (ViewHolder) convertView.getTag();
String detailsString = "";
double price = rowItem.getPrice();
for (RMOption i : rowItem.getOption()) {
detailsString += "-" + i.getName();
price += i.getExtraPrice();
}
holder.orderID = rowItem.getId();
holder.txtMenuName.setText(rowItem.getMenuName());
holder.txtMenuDesc.setText(detailsString);
holder.txtMenuPrice.setText(Double.toString(price) + " TL");
holder.deleteButton.setFocusable(false);
items = new ArrayList<RMOrder>(GlobalList.orderedItemsList.values());
clickedID = items.get(position).getId();
orderID = holder.orderID;
//change image of image button
if(rowItem.getStatus().equals("pending")){
holder.deleteButton.setImageResource(R.drawable.rsz_pending);
holder.deleteButton.setOnClickListener(new OnClickListener() {
//TODO Burada tıklananı bulmakta sıkıntı var
public void onClick(View v) {
//GET ORDER ID
}
});
else
holder.deleteButton.setImageResource(R.drawable.rsz_approved);
}
return convertView;
}
解决方案
Set the position as deleteButton tag
holder.deleteButton = (ImageButton) convertView.findViewById(R.id.menuDelete);
holder.deleteButton.setTag(position);
And then onClick
holder.deleteButton.setOnClickListener(new OnClickListener() {
//TODO Burada tıklananı bulmakta sıkıntı var
public void onClick(View v) {
int pos = Integer.parseInteger(v.getTag());
RMOrder rItem = getItem(pos);
int orderId = rowItem.getId();
}
});
