parcelable

Does anyone know where/when this method of a Parcelable is called? @Override public int describeContents() { return 0; } It has to be overriden. But should I consider doing something useful with it? Ognyan There is a constant defined in Parcelable called CONTENTS_FILE_DESCRIPTOR which is meant to be used in describeContents() to create bitmask return value. Description for CONTENTS_FILE_DESCRIPTOR in the API ref is: Bit masks for use with describeContents(): each bit represents a kind of object considered to have potential special significance when marshalled. Which really means: If you need

I have searched a few topics but not found a solution to my problem. public class Series implements Parcelable { private String name; private int numOfSeason; private int numOfEpisode; /** Constructors and Getters/Setters have been removed to make reading easier **/ public Series(Parcel in) { String[] data = new String[3]; in.readStringArray(data); this.name = data[0]; this.numOfSeason = Integer.parseInt(data[1]); this.numOfEpisode = Integer.parseInt(data[2]); } @Override public int describeContents() { return 0; } @Override public void writeToParcel(Parcel dest, int flags) { dest

So I got my AccessibilityService working with the following code: @Override public void onAccessibilityEvent(AccessibilityEvent event) { if (event.getEventType() == AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED) { List<CharSequence> notificationList = event.getText(); for (int i = 0; i < notificationList.size(); i++) { Toast.makeText(this.getApplicationContext(), notificationList.get(i), 1).show(); } } } It works fine for reading out the text displayed when the notifcation was created (1) . The only problem is, I also need the value of (3) which is displayed when the user opens the

I'm trying to make an ArrayList Parcelable in order to pass to an activity a list of custom object. I start writing a myObjectList class which extends ArrayList<myObject> and implement Parcelable . Some attributes of MyObject are boolean but Parcel don't have any method read/writeBoolean . What is the best way to handle this? Here's how I'd do it... writeToParcel: dest.writeByte((byte) (myBoolean ? 1 : 0)); //if myBoolean == true, byte == 1 readFromParcel: myBoolean = in.readByte() != 0; //myBoolean == true if byte != 0 You could also make use of the writeValue method. In my opinion that's the

how do i pass 2 denominational array object as a parameter to another activity how to get two dimensional array string value in another activity String [][]str; Intent l = new Intent(context,AgAppMenu.class); l.putExtra("msg",str); l.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(l); another Activity class String[][] xmlRespone2; xmlRespone2 = getIntent().getExtras().getString("msg"); You can use putSerializable. Arrays are serializable. To store: bundle.putSerializable("list", selected_list); // Here bundle is Bundle object. To access: String[][] passedString_list = (String[][
