我第一次只遇到这个错误所以我真的不知道如何修复它。我认为我的问题在于使用setText方法。我不知道为什么。在修改我的一些代码之前，我的代码完全正常。现在我收到了这个错误。以下是我的代码，

MyAdapter.java 

package com.functions;

import java.util.ArrayList;
import java.util.List;

import com.example.senditem.R;

import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.EditText;
import android.widget.Spinner;
import android.widget.TextView;

public class MyAdapter extends ArrayAdapter<Model> {

 private final List<Model> list;

 String adapter;
    private final Activity context;
    private final int id;
    int listPosition;
    public MyAdapter(Activity context, List<Model> list, int id){
        super(context, R.layout.userproduct, list);
        this.context = context;
        this.list = list;
        this.id = id;
    }


    class ViewHolder{
        protected TextView text;
        EditText quantity;
        protected TextView amount;
        protected Spinner uom;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent){
        listPosition = position;
        ViewHolder viewHolder = null;
        if(convertView == null){
            LayoutInflater inflator = context.getLayoutInflater();
            convertView = inflator.inflate(R.layout.userproduct, null);
            viewHolder = new ViewHolder(); 
            viewHolder.text = (TextView) convertView.findViewById(R.id.label);
            viewHolder.quantity = (EditText) convertView.findViewById(R.id.inputQty);

            convertView.setTag(R.id.inputUom, viewHolder.uom);
        }
        else{
            viewHolder = (ViewHolder) convertView.getTag();
        }
        SqliteHelper db = new SqliteHelper(context);
        viewHolder.text.setText(list.get(position).getName());
        viewHolder.quantity.setId(position);
        viewHolder.amount.setText(String.valueOf(Model.getAmt()));
        viewHolder.amount.setId(position);
        viewHolder.uom.setId(position);
        viewHolder.text.setId(position);
        String data = db.getAllDetails(id,Model.getitemId());
        if(data==null)
        {
             viewHolder.quantity.setText(list.get(position).quantity);

        }
        else{
            viewHolder.quantity.setText(data);
        }
        viewHolder.quantity.setOnFocusChangeListener(new View.OnFocusChangeListener() {
                public void onFocusChange(View v, boolean hasFocus) {
                    if (!hasFocus){
                        final int position = v.getId();
                        final EditText Caption = (EditText) v;



     list.get(position).quantity = Integer.parseInt(Caption.getText().toString());
                    }
                }
            });


        List<String> uomlist = new ArrayList<String>();

        for(int j=0;j<list.size();j++){
            String itemid = list.get(j).getitemId(); 
            uomlist.add(db.selectUom(itemid));

            ArrayAdapter<String> uomadapter = new ArrayAdapter<String>(getContext(),android.R.layout.simple_spinner_item,uomlist);
            uomadapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
            viewHolder.uom.setAdapter(uomadapter);

        }


        return convertView;

    }

1 个答案:

答案 0 :(得分：2)

你的错误应该在这一行：

    if(data==null)
    {
       //  viewHolder.quantity.setText(list.get(position).quantity); <---ERROR HERE
       //  Probably quantity is not a string, so use String.valueOf Function here
           viewHolder.quantity.setText(String.valueOf(list.get(position).quantity));

    }
    else{
        // data is already declared a string. So, String.valueOf is not required.
        viewHolder.quantity.setText(data);
    }

根据答案here setText with string显示这样的值，而setText with int则试图找到与int值匹配的资源。
