我正在使用contentobserver来监控SMS。它一切正常。当我尝试将这些短信保存到数据库时，它显示特定SMS的错误error near "t" syntax error。当我删除这个特定的SMS时，没有问题。安装后，它会按顺序正确显示所有消息。但是错误发送到我的数组列表的末尾。此后，从我的手机发送的短信在列表之间更新，而不是最后一个位置。请帮忙。arraylist未正确更新
adapter = new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_list_item_1,list);
setListAdapter(adapter);
data = Incoming_outgoing_smsActivity.this.openOrCreateDatabase("Messages", MODE_PRIVATE, null);
data.execSQL("CREATE TABLE IF NOT EXISTS recor(text varchar(300));");
Cursor cur = data.rawQuery("SELECT * FROM recor", null);
while(cur.moveToNext()) {
String content = cur.getString(cur.getColumnIndex("text"));
backward_list.add(content);
list.add(content);
}
adapter.notifyDataSetChanged();
Cursor cursor = getContentResolver().query(Uri.parse("content://sms"), null, null, null, null);
while(cursor.moveToNext()) {
String number = cursor.getString(cursor.getColumnIndex("address"));
String[] projection = new String[] {ContactsContract.PhoneLookup.DISPLAY_NAME};
Uri contactUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));
Cursor cursor_name = getContentResolver().query(contactUri, projection, null, null, null);
String body = cursor.getString(cursor.getColumnIndex("body"));
String type = cursor.getString(cursor.getColumnIndex("type"));
long date1= cursor.getLong(cursor.getColumnIndex("date"));
SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-yyyy hh:mm:ss.SSS");
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(date1);
try {
int n = cursor.getInt(cursor.getColumnIndex("type"));
switch (n) {
case 1:
String message = "FROM "+number+"\n"+formatter.format(calendar.getTime())+"\n"+"Message:-"+body;
if(backward_list.contains(message)) {
continue;
} else {
list.add(message);
backward_list.add(message);
data.execSQL("INSERT INTO recor VALUES('"+message+"')");
}
break;
case 2:
String messag = "TO "+number+"\n"+formatter.format(calendar.getTime())+"\n"+"Message:-"+body;

上面的代码保存在收件箱中，以数据库的当前短信。下面的代码用于在新短信到达时更新您的收件箱。它为到达的消息做烤面包，但不会将它们插入到数据库中。
