How to get data from a parse object?

I have a class in parse.com called Messages. I have created a column called sent of type string which stores the object-id of the user to whom the message has to be sent. In my android app I want to retrieve the messages of the current user. But my app does not show any messages.

This is how I'm implementing it-

public void done(List<ParseObject> postList, ParseException e) {
setProgressBarIndeterminateVisibility(false);
if (e == null) {
// If there are results, update the list of posts
// and notify the adapter
posts.clear();   //posts is a list of <TextMessage>
//TextMessage is a class which holds the details of Messages (parse object)

for (ParseObject msg : postList) {

if(msg.getParseUser("sent")==ParseUser.getCurrentUser())
{
    TextMessage note = new TextMessage(msg.getObjectId());
    posts.add(note);
}

}
    ((ArrayAdapter<TextMessage>) getListAdapter()).notifyDataSetChanged();
}

I can't understand why the if conditions are not being implemented, what am I doing wrong. How else can I retrieve the string in the sent column? Feel free to ask for any more information required.

I am not android expert but I think your issue is :

If you care comparing two strings, you must use equals() not ==

Change == to equals() everything works

Note: == checks the reference to the object are equal .

Note: equals() This method compares this string to the specified object. The result is true if and only if the argument is not null and is a String object that represents the same sequence of characters as this object

read about equals()
