Widget is resizable in the horizontal axis only.
Constant Value: 1 (0x00000001)
RESIZE_NONE
public static final int RESIZE_NONE
Widget is not resizable.
Constant Value: 0 (0x00000000)
RESIZE_VERTICAL
public static final int RESIZE_VERTICAL
Widget is resizable in the vertical axis only.
Constant Value: 2 (0x00000002)
WIDGET_CATEGORY_HOME_SCREEN
public static final int WIDGET_CATEGORY_HOME_SCREEN
Indicates that the widget can be displayed on the home screen. This is the default value.

Public constructors

Unflatten the AppWidgetProviderInfo from a parcel.
Parameters | |
---|---|
in | Parcel |
Public methods
clone
public AppWidgetProviderInfo clone ()
Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object x
, the expression:
will be true, and that the expression: x.clone() != x
will be x.clone().getClass() == x.getClass()
true
, but these are not absolute requirements. While it is typically the case that: will be x.clone().equals(x)
true
, this is not an absolute requirement. By convention, the returned object should be obtained by calling super.clone
. If a class and all of its superclasses (except Object
) obey this convention, it will be the case that x.clone().getClass() == x.getClass()
.
By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned by super.clone
before returning it. Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies. If a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by super.clone
need to be modified.
Returns | |

describeContents
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)

bit.
