I've implemented a basic gesture detection system in my app with the
following code (taken from an Android sample):
mGestureLibrary = GestureLibraries.fromRawResource(this,
R.raw.gestures);
if (!mGestureLibrary.load()) {
finish();
}
gestures = (GestureOverlayView) findViewById(R.id.gestures);
gestures.addOnGesturePerformedListener(this);
gesturedItems = new ArrayList<String>();
public void onGesturePerformed(GestureOverlayView overlay, Gesture
gesture) {
ArrayList<Prediction> predictions =
mGestureLibrary.recognize(gesture);
if (predictions.size() > 0 && predictions.get(0).score > 1.0)
{
String action = predictions.get(0).name;
if ("line".equals(action)) {
gesturedItems.add
}
}
}
(My Activity here implements OnGesturePerformedListener).
My gestures are being detected on a scrolling GridView. Each element
in the GridView is implemented with a ViewHolder. So, when I open a
context menu on a single item, I can get metadata about it like its
ID, in order to perform further actions like delete, rename, e.t.c.
I want to grab that same ViewHolder metadata information through my
gesture. Is that possible? I don't necessarily want the gesture to
equal a long press--I intend to build a list of IDs of each item that
the gesture picks up.
