将时间与移动时间进行比较

Question

我的列表视图中有两个计时和一个按钮，它们之间的时差是10分钟。我想要的是我的移动时间到达newtime时必须单击才能单击的时间，以下是无法单击的代码：

SecondCustom.java

public class SecondCustom extends BaseAdapter {
    Activity a;
    ArrayList<Model> timelist;
    Date newtime;
    Time itime,canceltime;


    public SecondCustom(Activity a, ArrayList<Model> timelist) {
        this.a = a;
        this.timelist= timelist;
    }

    @Override
    public int getCount() {
        return timelist.size();
    }

    @Override
    public Object getItem(int i) {
        return timelist.get(i);
    }

    @Override
    public long getItemId(int i) {
        return i;
    }



    public class Viewholder{
        TextView srno, ctime, ltime;
        Button buy;
    }

    @Override
    public View getView(final int i, View convertView, ViewGroup viewGroup) {
        Viewholder viewholder=null;
        if (convertView == null) {
            viewholder = new Viewholder();
            LayoutInflater li = a.getLayoutInflater();
            convertView = li.inflate(R.layout.secondcustom, viewGroup, false);

            viewholder.srno = (TextView) convertView.findViewById(R.id.sr);
            viewholder.ctime = (TextView) convertView.findViewById(R.id.currenttime);



            viewholder.buy = (Button) convertView.findViewById(R.id.st);
            viewholder.ltime = (TextView) convertView.findViewById(R.id.lefttime);
            convertView.setTag(viewholder);
        }
        else {
            viewholder = (Viewholder) convertView.getTag();
        }


        Model model=timelist.get(i);
        viewholder.srno.setText(valueOf(timelist.get(i).getSr()));



        String Time = DateFormat.getTimeInstance().format(new Date());
        viewholder.ctime.setText(Time);

     Calendar cal = Calendar.getInstance();
        SimpleDateFormat sd = new SimpleDateFormat("HH:mm:ss a");

        cal.add(Calendar.MINUTE,10); 
     String FutTime= sd.format(cal.getTime());
        viewholder.ltime.setText(FutTime);


        viewholder.buy.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    Toast.makeText(a, "Purchased" + " " + flowerlist.get(i).getSr(), Toast.LENGTH_LONG).show();
                }
            });

        return convertView;
    }
}

Answer 1

使用处理程序使按钮在10分钟后可点击。

伪代码应如下所示-

new Handler().postDelayed(new Runnable() {
              public void run() {
               viewholder.buy.setclickable(true);

            }
        }, 10*60*1000);

Answer 2

new CountDownTimer(30000, 1000) {

    public void onTick(long millisUntilFinished) {
        mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
       //here you can have your logic to set text to edittext
    }

    public void onFinish() {
        mTextField.setText("done!");
    }

}.start();

使用countDownTimer满足您的要求。 当您的计时器结束时，它将给事件onFinish（）。 这样就可以执行操作了。

Answer 3

倒数计时器可以解决您的问题，将sleepTime设置为倒数计时器10秒

viewholder.buy.setclickable(false);
mCountDownTimer = new CountDownTimer(sleepTime, 1000) {

                public void onTick(long millisUntilFinished) {


                    String hms = String.format("%02d:%02d:%02d", TimeUnit.MILLISECONDS.toHours(millisUntilFinished),
                            TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished) - TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millisUntilFinished)),
                            TimeUnit.MILLISECONDS.toSeconds(millisUntilFinished) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished)));
                    txtTimer.setText(hms);//display the time 
                }
                public void onFinish() {
                    txtTimer.setText("00:00:00");
                    viewholder.buy.setclickable(true);

                }
            }.start();
