Question

我正在研究这个小型游戏，每500毫秒将一个图像设置为图像视图所以我要检查的是当我点击其中一个箭头图像（左，右，上，下）来检查它是否等于随机图像...如果是，则分数增加1。这是我的布局 https://i.stack.imgur.com/wPxZB.png

这是我的代码

您正在检查索引中的数据，并且您需要该位置，因此请改用：

pos = Array.asList(arrayBuckets).indexOf((int) (Math.random() * arrBuckets.length));

img_up.setOnClickListener(new View.OnClickListener() { 
        @Override public void onClick(View view) {
         if(pos==2)
            {
        SCORE++; 
        score.setText(SCORE+""); 
        }

        });
