android - Get scrollview on top event -


i have code on gridview on touch event.

        gridview.setontouchlistener(new ontouchlistener() {          @override         public boolean ontouch(view v, motionevent event) {             // todo auto-generated method stub             int action = event.getaction();             switch (action) {             case motionevent.action_down:                 // disallow scrollview intercept touch events.                 v.getparent().requestdisallowintercepttouchevent(true);                 break;              case motionevent.action_up:                 // allow scrollview intercept touch events.                 v.getparent().requestdisallowintercepttouchevent(false);                 break;             }              // handle listview touch events.             v.ontouchevent(event);             return true;         }     });

inside motionevent.action_up case, want this.

if(v.getparent().scrollisontop){     v.getparent().requestdisallowintercepttouchevent(false);     } else{     v.getparent().requestdisallowintercepttouchevent(true);     }

mean when parent scroll on top, disallow scrollview intercept

else allow scrollview intercept.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
