(用qr code掃描後發票對獎)
專案的MainActivity裡有一個fab (寫在觸發qr code的事件裡)
(附上MainActivity連結:https://github.com/steveTW/ReceiptLottery/blob/master/app/src/main/java/my/receiptlottery/com/activity/MainActivity.java

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        //CaptureReceiptLotteryTask task = new CaptureReceiptLotteryTask();
        //task.execute(MainActivity.this);
    }

原作者打的onClick裡沒東西所以那個fab按下去後是沒有反應的
下面兩行不要註解的話則是跳出發票號碼已更新

請問onClick裡面要怎麼打呢謝謝
