Gallery Judge Scroll start and stop

To do some processing when the gallery starts sliding and at the end of the slide, you need to know the timing of the start and stop of the slide.

1. The time to start

Gallery Mcoverflowview = new Gallery (context);

Final Gesturedetectorcompat Mgesturedetectorcompat = new Gesturedetectorcompat (this, this);

Mcoverflowview.setontouchlistener (New Ontouchlistener () {

@Override

public boolean OnTouch (View V, motionevent event) {

Return Mgesturedetectorcompat.ontouchevent (event);

}

});

　　

});

The Ongesturelistener can then be used in the

@Override

public boolean onscroll (Motionevent E1, motionevent E2, float Distancex,

Float Distancey) {

Adding processing logic at start of slide

return false;

}

2. Determine when gallery stops

Mcoverflowview.setcallbackduringfling (FALSE);

Mcoverflowview.setonitemselectedlistener (New Onitemselectedlistener () {

@Override

public void onitemselected (adapterview<?> parent, view view,

int position, long ID) {

Add sliding end processing logic

}

@Override

public void onnothingselected (adapterview<?> parent) {

}

});
