SurfaceControlViewHost.SurfacePackage
extends Object
implements
Parcelable
java.lang.Object | |
↳ | android.view.SurfaceControlViewHost.SurfacePackage |
Package encapsulating a Surface hierarchy which contains interactive view
elements. It's expected to get this object from
SurfaceControlViewHost#getSurfacePackage
afterwards it can be embedded within
a SurfaceView by calling SurfaceView#setChildSurfacePackage
.
Note that each SurfacePackage
must be released by calling
SurfacePackage#release
. However, if you use the recommended flow,
the framework will automatically handle the lifetime for you.
1. When sending the package to the remote process, return it from an AIDL method
or manually use FLAG_WRITE_RETURN_VALUE in writeToParcel. This will automatically
release the package in the local process.
2. In the remote process, consume the package using SurfaceView. This way the
SurfaceView will take over the lifetime and call SurfacePackage#release
for the user.
One final note: The SurfacePackage
lifetime is totally de-coupled
from the lifetime of the underlying SurfaceControlViewHost
. Regardless
of the lifetime of the package the user should still call
SurfaceControlViewHost#release
when finished.

public int describeContents ()
Describe the kinds of special objects contained in this Parcelable
instance's marshaled representation. For example, if the object will
include a file descriptor in the output of writeToParcel(android.os.Parcel, int)
,
the return value of this method must include the
CONTENTS_FILE_DESCRIPTOR
bit.
Returns | |
---|---|
int |
a bitmask indicating the set of special object types marshaled
by this Parcelable object instance.
Value is either 0 or CONTENTS_FILE_DESCRIPTOR |
public void release ()
Release the SurfaceControl
associated with this package.
It's not necessary to call this if you pass the package to
SurfaceView#setChildSurfacePackage
as SurfaceView
will
take ownership in that case.
public void writeToParcel (Parcel out, int flags)
Flatten this object in to a Parcel.
Parameters | |
---|---|
out |
Parcel : This value cannot be null . |
flags |
int : Additional flags about how the object should be written.
May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE .
Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE , and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
