我为此应用程序设置了一个计时器,因此,当计时器结束并且仍选中Itemdata中的框时,它应调用Thank.class活动。
但是,我意识到它多次对Thanks.class活动进行了分类。
例如。如果有3个选定的项目,它将调用Thank.class活动3次。

这是我宣布的计时器

    //Declare timer
CountDownTimer cTimer = null;

//start timer function
void startTimer() {
    cTimer = new CountDownTimer(10000, 1000) {
        public void onTick(long millisUntilFinished) {
        }
        public void onFinish() {
            Intent intent = new Intent(ctx, Thanks.class);
            ctx.startActivity(intent);
        }
    };
    cTimer.start();

}
//cancel timer
void cancelTimer() {
    if(cTimer!=null)
        cTimer.cancel();
}


这是我如何调用该函数。

@Override
public View getView(final int position, final View view, ViewGroup parent) {
    final GridItemData itemData = getItem(position);
    inflater = (LayoutInflater) ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    final View itemView = inflater.inflate(R.layout.grid_image, parent, false);

    ivGallery = itemView.findViewById(R.id.grid_item_image);
    ivGallery.setImageResource(getItem(position).imageUrl);
    final MainActivity main = new MainActivity();

    itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            ivGallery = itemView.findViewById(R.id.grid_item_image);
            itemData.setSelected(!itemData.isSelected());
            startTimer();
            if(itemData == getItem(8)) {
                AlertDialog.Builder builder = new AlertDialog.Builder(v.getContext());
                customizeAlert(builder, v);
                builder.show();
            }
            else if (itemData == getItem(0)) {
                ivGallery.setImageResource(itemData.isSelected()?R.drawable.clickfloor: R.drawable.floor);
            }
            else if (itemData == getItem(1)) {
                ivGallery.setImageResource(itemData.isSelected()?R.drawable.cb: R.drawable.wb);
            }
            else if (itemData == getItem(2)) {
                ivGallery.setImageResource(itemData.isSelected()?R.drawable.cs: R.drawable.s);
            }
            else if (itemData == getItem(3)) {
                ivGallery.setImageResource(itemData.isSelected()?R.drawable.clickothers: R.drawable.others);
            }
          }
    });

    return itemView;
}


请告诉我该怎么办,谢谢!

最佳答案

只启动一次CountDownTimer怎么样?

void startTimer() {
    if(cTimer == null) {
        cTimer = new CountDownTimer(10000, 1000) {
            public void onTick(long millisUntilFinished) {
            }
            public void onFinish() {
                Intent intent = new Intent(ctx, Thanks.class);
                ctx.startActivity(intent);
            }
        };
        cTimer.start();
    }
}


或者,当第二个CountDownTimer将要启动时,只需停止第一个。
