Returns the value associated with the given key, or null if no mapping of the desired type exists for the given key or a null value is explicitly associated with the key.

Note: if the expected value is not a class provided by the Android platform, you must call setClassLoader(java.lang.ClassLoader) with the proper ClassLoader first. Otherwise, this method might throw an exception or return null.

Parameters
key String: a String, or null

Returns
T a Parcelable value, or null

getParcelable

Added in API level 33
public T getParcelable (String key, 
                Class<T> clazz)

  • No mapping of the desired type exists for the given key.
  • A null value is explicitly associated with the key.
  • The object is not of type clazz.

Note: if the expected value is not a class provided by the Android platform, you must call setClassLoader(java.lang.ClassLoader) with the proper ClassLoader first. Otherwise, this method might throw an exception or return null.

Warning: the class that implements Parcelable has to be the immediately enclosing class of the runtime type of its CREATOR field (that is, Class#getEnclosingClass() has to return the parcelable implementing class), otherwise this method might throw an exception. If the Parcelable class does not enclose the CREATOR, use the deprecated getParcelable(java.lang.String) instead.

Warning: if the list contains items implementing the Parcelable interface, the class that implements Parcelable has to be the immediately enclosing class of the runtime type of its CREATOR field (that is, Class#getEnclosingClass() has to return the parcelable implementing class), otherwise this method might throw an exception. If the Parcelable class does not enclose the CREATOR, use the deprecated getParcelableArray(java.lang.String) instead.

Parameters

Returns
T[] a Parcelable[] value, or null
