android - ListView 中的 ArrayIndexOutOfBounds 异常

Question

我有以下数组适配器:

public class SmsArrayAdapter extends ArrayAdapter<String> {

    List<String> smsBody;
    List<Boolean> Status;
    List<String> time;
    List<String> SmsMessageId;

    Context context;
    private static LayoutInflater inflater = null;
    String fromNumber;

    public SmsArrayAdapter(Context context, int resource, List<String> smsBody,
            List<Boolean> Status, List<String> time, List<String> SmsMessageId,
            String fromNumber) {
        super(context, resource, smsBody);
        this.smsBody = smsBody;
        this.Status = Status;
        this.context = context;
        inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        this.fromNumber = fromNumber;
        this.time = time;
        this.SmsMessageId = SmsMessageId;
    }

    public String getStr(int position) {
        return smsBody.get(position);
    }

    public String getId(int position) {
        return SmsMessageId.get(position);
    }

    public void setRead(int position, String smsMessageId) {
        Status.set(position, true);
        ContentValues values = new ContentValues();
        values.put("read", true);
        context.getContentResolver().update(Uri.parse("content://sms/inbox"),
                values, "_id=" + smsMessageId, null);
    }

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

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

    public static class ViewHolder {
        public TextView textfrom;
        public TextView text_sms;
        public TextView text_time;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        ViewHolder holder;
        if (convertView == null) {

            /****** Inflate tabitem.xml file for each row ( Defined below ) *******/
            convertView = inflater.inflate(R.layout.row_item, null);

            /****** View Holder Object to contain tabitem.xml file elements ******/

            holder = new ViewHolder();

            holder.textfrom = (TextView) convertView
                    .findViewById(R.id.textView_from);
            holder.text_sms = (TextView) convertView
                    .findViewById(R.id.textView_sms);
            holder.text_time = (TextView) convertView
                    .findViewById(R.id.textView_time);

            /************ Set holder with LayoutInflater ************/
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }

        holder.textfrom.setText(" " + fromNumber);

        String smsTextToDisplay = smsBody.get(position);
        if (smsTextToDisplay.length() > 100)
            smsTextToDisplay = smsTextToDisplay.substring(0, 99) + " ...";

        holder.text_sms.setText(smsTextToDisplay);

        holder.text_time.setText(time.get(position));
        if (Status.get(position) == false) {
            convertView.setBackgroundColor(context.getResources().getColor(
                    R.color.light_blue_overlay));
        }

        return convertView;
    }

}

但是当我使用这个 ListView 时，出现以下异常。

为什么我会收到这个错误？我怎样才能避免这个错误？

Answer 1

不良做法

List<String> smsBody;
List<Boolean> Status;
List<String> time;
List<String> SmsMessageId;

最佳做法是管理不同的 ArrayList 以管理同一对象的数据。在进行添加或删除数据等操作时，您很难管理不同的 ArrayList。

例如，如果您想添加数据，则必须为每个列表中的相同索引添加数据。

管理 ArrayList 数据的最佳实践

最好的做法是管理具有用户定义对象的单个 ArrayList，例如ArrayList<SMSModel> .

其中 SMSModel 是一个模型类，它具有与 SMS 对象相关的所有属性，如 SMSBody、时间、SMS 消息等，并且该模型类将包含 getter/setter 方法以从对象获取和设置项目。
