Method Detail

getParcelableArray

public static <T extends android.os.Parcelable> T[] getParcelableArray(android.os.Bundle bundle,
                                                                       String key,
                                                                       Class<T[]> type)

This method extracts a Parcelable array from the Bundle, and returns it in an array whose type is the exact Parcelable subclass. This is needed because Bundle.getParcelable(String) returns an array of Parcelable, and we would get ClassCastException when we assign it to Parcelable subclass arrays. For more info, see this url.

Type Parameters:

T - the element type of the returned array

Parameters:

bundle - the bundle holding the array which is extracted

key - the array is associated with this key

type - the desired type of the returned array

Returns:

a Parcelable subclass typed array which holds the objects from Bundle.getParcelableArray(String) or null if Bundle.getParcelableArray(String) returned null for the key
