public class StaggeredGridView extends ViewGroup
StaggeredGridView presents a multi-column grid with consistent column sizes
but varying row sizes between the columns. Each successive item from a
ListAdapter
will be arranged from top to bottom,
left to right. The largest vertical gap is always filled first.
Item views may span multiple columns as specified by their StaggeredGridView.LayoutParams
.
The attribute android:layout_span
may be used when inflating
item views from xml.
This class is still under development and is not fully functional yet.

ViewGroup
Using this function takes some care, as it has a fairly complicated
interaction with View.onTouchEvent(MotionEvent)
, and using it requires implementing
that method as well as this one in the correct way. Events will be
received in the following order:
MotionEvent.ACTION_CANCEL
, and all further
events will be delivered to your onTouchEvent() method and no longer
appear here.

If this method is used to detect click actions, it is recommended that
the actions be performed by implementing and calling
View.performClick()
. This will ensure consistent system behavior,
including:

public void requestLayout()
View
View.isInLayout()
. If layout is happening, the request may be honored at the
end of the current layout pass (and then layout will run again) or after the current

Subclasses which override this method should call the superclass method to handle possible request-during-layout errors correctly.

protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
View
Measure the view and its content to determine the measured width and the
measured height. This method is invoked by View.measure(int, int)
and
should be overridden by subclasses to provide accurate and efficient
measurement of their contents.
CONTRACT: When overriding this method, you
must call View.setMeasuredDimension(int, int)
to store the
measured width and height of this view. Failure to do so will trigger an
IllegalStateException
, thrown by
View.measure(int, int)
. Calling the superclass'
View.onMeasure(int, int)
is a valid use.
The base class implementation of measure defaults to the background size,
unless a larger size is allowed by the MeasureSpec. Subclasses should
override View.onMeasure(int, int)
to provide better measurements of
their content.
If this method is overridden, it is the subclass's responsibility to make
sure the measured height and width are at least the view's minimum height
and width (View.getSuggestedMinimumHeight()
and
View.getSuggestedMinimumWidth()
).
