我有下面的代碼來顯示彈出式菜單,當用戶單擊每個行項目中的溢出圖像時。不幸的是,我不知道如何將上下文傳遞給導致onClick()沒有獲取上下文值的片段。我設法顯示彈出式菜單,如果我直接在適配器類的getView()中創建監聽器,但我不能得到預期的結果,如果我將偵聽器傳遞給片段。我可以知道如何適應我的代碼?從片段到適配器類的Android傳遞值
我現在的編碼是如下:
public class SubProductCustomAdapter extends BaseAdapter {
...
@Override
public View getView(int position, View convertView, ViewGroup parent) {
//RecyclerView (Android 5.0) - To avoid app crash when there are too many records when user scroll
ViewHolder viewHolder;
LayoutInflater mInflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
//First Created
if(convertView == null)
{
convertView = mInflater.inflate(R.layout.item_sub_product, null);
viewHolder = new ViewHolder();
viewHolder.sub_product_name = (TextView)convertView.findViewById(R.id.txt_pdt_name);
viewHolder.popup_menu = (ImageView) convertView.findViewById(R.id.product_overflow);
SubRowProducts subRowPro = subRowProducts.get(position);
viewHolder.sub_product_name.setText(subRowPro.getSub_product_name());
//Managed to display popup menu using below method
/*viewHolder.popup_menu.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
PopupMenu popupMenu = new PopupMenu(context,v);
popupMenu.getMenuInflater().inflate(R.menu.drawermenu, popupMenu.getMenu());
popupMenu.show();
}
});*/
//Not managed to display popup menu using below method
viewHolder.popup_menu.setOnClickListener(new MySubProductListFragment());
//Store object inside convert view
convertView.setTag(viewHolder);
}
else{
//Reused or recycle the convertView
viewHolder = (ViewHolder)convertView.getTag();
}
//viewHolder.sub_product_name.setText(subRowProducts.get(position).getSub_product_name());
return convertView;
}
。
