我正在处理邮件应用程序，并希望在新邮件到达时更新我的自定义listView。我已经尝试了几种方法来做到这一点但是没有成功...请帮助完整的描述因为新的android。这是我的代码
public class SMSBroadcastReceiver extends BroadcastReceiver {
Messages message1;
MessageDbHelper db;
Context context=null;
SmsInboxList smsInboxList;
BroadcastReceiver br;
// ADapter adap;
private static final String ACTION = "android.provider.Telephony.SMS_RECEIVED";
IntentFilter intentFilter=new IntentFilter(ACTION);
@SuppressLint("SimpleDateFormat")
@Override
public void onReceive(Context context, Intent intent) {
// Retrieves a map of extended data from the intent.
Bundle bundle = intent.getExtras();
message1 = new Messages();
this.context=context;
// context = context.getApplicationContext();
smsInboxList = new SmsInboxList();
// adap=new ADapter(context, R.id.listView_Conversation);
MessageDbHelper dbMessagedbHelper = new MessageDbHelper(context, null,null, 0);
db = dbMessagedbHelper;
try {
if (bundle != null) {
Object[] pdusObj = (Object[]) bundle.get("pdus");
for (int i = 0; i < pdusObj.length; i++) {
SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
String phoneNumber = currentMessage.getDisplayOriginatingAddress();
String senderNum = phoneNumber;
String message = currentMessage.getDisplayMessageBody();
Long localLong = Long.valueOf(currentMessage.getTimestampMillis());
String datae = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date(localLong.longValue()));
/*****************

try {
message1.body(message);
message1.number(senderNum);

db.insertDataInMsgTable(message1);
createNotification(context, message1);
} catch (Exception e) {
Log.i("", "except" + e);
}
Log.i("SmsReceiver", "senderNum: " + senderNum

}
}
}
}
public void createNotification(Context context, Messages message1) {

答案 0 :(得分：3)
使用
listView.invalidate();
例如您在listView中添加/删除/更新了数据。
答案 1 :(得分：0)
只是一个想法：
将您的代码public CategoryListAdapter1 adapter;称为全球课程。
只要您的列表要刷新，请使用adapter.notifyDataSetChanged();。
