我正在使用 ListView 在 Android 中动态添加复选框。我正在使用 ContextAdapter 类来增加 ListView。 我的错误日志如下:

ContextAdapter类如下:

import android.app.Activity;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.CheckBox;
import android.widget.TextView;

public class CustomAdapter extends ArrayAdapter<ListData>{

    ListData[] items = null;
    Context context;

    public CustomAdapter(Context context, ListData[] resource) {
        super(context, R.layout.activity_list_row, resource);
        // TODO Auto-generated constructor stub
        this.context = context;
        this.items = resource;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        LayoutInflater inflator = ((Activity) context).getLayoutInflater();
        convertView = inflator.inflate(R.layout.activity_list_row, parent, false);
        TextView name = (TextView) convertView.findViewById(R.id.NameTV);
        TextView rollNo = (TextView) convertView.findViewById(R.id.RollNoTV);
        CheckBox cb = (CheckBox) convertView.findViewById(R.id.studentCB);
        name.setText(items[position].getName());
        rollNo.setText(items[position].getRollNo());

        if(items[position].getValue() == 1)
            cb.setChecked(true);
        else
            cb.setChecked(false);

        return convertView;
    }   
}

我的 ListData 类:

package com.project.attendancemanager;

public class ListData {

    String name;
    int value, rollno;

    ListData(String name, int rollno, int value){
        this.name = name;
        this.rollno = rollno;
        this.value = value;
    }

    public String getName(){
        return this.name;
    }

    public int getRollNo(){ 
        return this.rollno;
    }

    public int getValue(){  
        return this.value;
    }

}

在 Activity 的 onCreate 函数中，我正在这样做:

Listview lv;
ListData[] items;
CustomAdapter adapter = new CustomAdapter(this, items);
lv.setAdapter(adapter);

如果有人能指出我的代码中的错误，那将非常有帮助。 谢谢!干杯!

最佳答案

代替

rollNo.setText(items[position].getRollNo());

你应该使用

rollNo.setText(Integer.toString(items[position].getRollNo()));

如果您尝试将整数设置为文本，则调用方法 setText(int resID) 并且应用程序尝试将具有此 resID 的某些字符串资源设置为文本。
