It is a trivial process. You can see a good example in the source code
SMSPopup
Examine the following methods:
public static SmsMmsMessage getSmsDetails(Context context,
long ignoreThreadId, boolean unreadOnly)
public static long findMessageId(Context context, long threadId, long _timestamp, int messageType
public static void setMessageRead(Context context, long messageId, int messageType)
public static void deleteMessage(Context context, long messageId, long threadId, int messageType)
this is the method for reading:
public static SmsMmsMessage getSmsDetails(Context context,
long ignoreThreadId, boolean unreadOnly) {
String SMS_READ_COLUMN = "read";
String WHERE_CONDITION = unreadOnly ? SMS_READ_COLUMN + " = 0" : null;
String SORT_ORDER = "date DESC";
int count = 0;
//Log.v(WHERE_CONDITION);
if (ignoreThreadId > 0) {
// Log.v("Ignoring sms threadId = " + ignoreThreadId);
WHERE_CONDITION += " AND thread_id != " + ignoreThreadId;
}
Cursor cursor = context.getContentResolver().query(
SMS_INBOX_CONTENT_URI,
new String[] { "_id", "thread_id", "address", "person", "date", "body" },
WHERE_CONDITION,
null,
SORT_ORDER);
if (cursor != null) {
try {
count = cursor.getCount();
if (count > 0) {
cursor.moveToFirst();
// String[] columns = cursor.getColumnNames();
// for (int i=0; i<columns.length; i++) {
// Log.v("columns " + i + ": " + columns[i] + ": "
// + cursor.getString(i));
// }
long messageId = cursor.getLong(0);
long threadId = cursor.getLong(1);
String address = cursor.getString(2);
long contactId = cursor.getLong(3);
String contactId_string = String.valueOf(contactId);
long timestamp = cursor.getLong(4);
String body = cursor.getString(5);
if (!unreadOnly) {
count = 0;
}
SmsMmsMessage smsMessage = new SmsMmsMessage(
context, address, contactId_string, body, timestamp,
threadId, count, messageId, SmsMmsMessage.MESSAGE_TYPE_SMS);
return smsMessage;
}
} finally {
cursor.close();
}
}
return null;
