How to pass an array of Address objects to an other Acitvity

由 戏子无情 提交于 2019-12-10 14:18:41
问题 I'm trying to pass an array of Address objects to another Activity through an Intent object. As the Address class implements the Parcelable interface I try to do the following. I got a List Address object from a Geocoder object, which I convert into a array of Address objects. Then I put this array into the Intent and call the activity. final Address[] addresses = addresseList.toArray(new Address[addresseList.size()]); final Intent intent = new Intent(this, SelectAddress.class); intent

问题 I've gone through this: How to send an object from one Android Activity to another using Intents? But i'm facing problem in sending images in the object to the other activity.

Android - polymorphism and Parcelable

由 冷暖自知 提交于 2019-12-10 09:24:45
问题 I can't figure out how to use polymorohism when writing/reading from parcel. I understand that I need to implement Parcelable in base class, and also in all derived classes (in the case that subclasses have additional properties that I would want to write into parcel). What I don't understand and what I don't know if it's even possible is - how to read subclass from Parcelable i.e., how do I know what kind of subclass I am reading from parcel. I can do some hack like writing some indicator

问题 I have been writing Parcelable s to Parcel without any focus on flags field, which is a parameter in the method signature and it has worked fine but I have run into an implementation where I can no longer ignore them: public static <K extends Parcelable, V extends Parcelable> void write(Parcel dest, Map<K, V> map, int flags) { if (map == null) { dest.writeInt(-1); } else { Set<Map.Entry<K, V>> entrySet = map.entrySet(); dest.writeInt(entrySet.size()); for (Map.Entry<K, V> entry : entrySet) {

Passing a Cursor between processes (Parcelable Cursor)

由 不问归期 提交于 2019-12-09 13:15:23
问题 I need to pass a Cursor ( SQLiteCursor ) from a service to an application on API 10 , and having hard time finding a decent (and fast) solution. I've seen the CursorWindow class. This is Parcelable but I can't instantiate this class on API 10 to use SQLiteCursor.fillWindow() because it has no valid constructors. CursorWindow(boolean) is deprecated. And even if I got a CursorWindow instance with data from a SQLiteCursor , how do I copy this window into a new Cursor ? What Cursor implementation
