我有一个SMSItem对象的列表视图。当任何新的短信到达时，它会显示在列表中。但是在单击列表或重新启动活动后，该项目正在消失。该项目未显示在列表中。
我的清单文件如下：

如果清单文件如下，则列表中的项目不会消失。但该应用程序未设置为默认值。

问题出在哪里。我该如何解决这个问题？
适配器的代码如下：
public class SmsArrayAdapter extends ArrayAdapter<SMSItem> {
List<SMSItem> smsBody;
Context context;
private static LayoutInflater inflater = null;
String fromNumber;
public SmsArrayAdapter(Context context, int resource,
List<SMSItem> smsBody, String fromNumber) {
super(context, resource, smsBody);
this.smsBody = smsBody;
this.context = context;
inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
this.fromNumber = fromNumber;
}
public SMSItem getStr(int position) {
return smsBody.get(position);
}
public void setRead(int position, String smsMessageId) {
smsBody.get(position).status = true;
SMSItem smsItem = smsBody.get(position);
smsItem.status = true;
//smsBody.set(position, smsItem);
ContentValues values = new ContentValues();
values.put("read",true);
int flag = context.getContentResolver().update(Uri.parse("content://sms/inbox"),
values, "_id=" + smsMessageId, null);
Toast.makeText(context, "The result is "+flag, Toast.LENGTH_LONG).show();
/* Uri uri = Uri.parse("content://sms/inbox");
String selection = "address = ? AND body = ? AND read = ?";
String from = "03590000004";
String body =smsItem.sms;
String[] selectionArgs = {from, body, "0"};
ContentValues values = new ContentValues();
values.put("read", true);
int flag = context.getContentResolver().update(uri, values, selection, selectionArgs);
Toast.makeText(context, "The result is "+flag, Toast.LENGTH_LONG).show(); */
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return super.getCount();
}
@Override
public SMSItem 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) {
// Toast.makeText(context, "The index is "+position, Toast.LENGTH_LONG).show();
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);
SMSItem smsItem = smsBody.get(position);
String smsTextToDisplay = smsItem.sms;
if (smsTextToDisplay.length() > 100)
smsTextToDisplay = smsTextToDisplay.substring(0, 99) + " ...";
holder.text_sms.setText(smsTextToDisplay);
holder.text_time.setText(smsItem.time);
if (smsItem.status == false) {
convertView.setBackgroundColor(context.getResources().getColor(
R.color.light_blue_overlay));
}
else
{
convertView.setBackgroundColor(Color.WHITE);
}
return convertView;
}
}
