If you want to initialize the gap pointing to the disc, you need to make a brief modification!

DEMO

MLottery = Lottery. newInstance (mWheel, new OnLotteryListener () {@ Override public void onLotteryStop (int level) {Flog. I ("onLotteryStop:" + level) ;}@ Override public void onLotteryStart () {Flog. I ("onLotteryStart ");}}). setLevel (10) // a total of several awards. setLevelMap (new int [] {5, 1, 1, 1, 1, 1, 1, 1, 1}) // ing award. setTimeOut (4 );

After obtaining the server value, call

MLottery. stop (5); // The parameter number.
