使用Intent将RealmQuery对象传递给Activity

Question

I have an Activity that creates a RealmQuery<E> and I need to pass this query to another Activity to execute it. I can't do this using an Intent as the object I'm trying to pass is not parcelable. How can this be achieved?

Answer 1

Passing data back and forth Activity can be achieved with Intent Extra.

You can simply do the following

First Activity Firstly obtain your data into variable its datatype

String uid = myModel.getUid();

Sending data to ChefProfile class

Intent intent = new Intent(MainActivity.this, ChefProfile.class);
intent.putExtra(ChefProfile.EXTRA_USER_ID, uid);
startActivity(intent);

Now let get the data from Intent since it has arrived to the calling activity

This is Chef_Profile class. Firstly, we have to create a constant field for the data arrived.

private static final String EXTRA_USER_KEY = "uid";

//Here we obtain the data sent from first activity and extract it into userId
userId = getIntent().getStringExtra(EXTRA_USER_KEY);
if (userId == null) {
    throw new IllegalArgumentException("Must pass EXTRA_POST_KEY");
}
