Question

我想要做的是每次点击TextView时，星星都会得到我在布局中设置的随机位置。

首次点击后它会起作用，但下一次点击文字视图时会遗漏一些星星。

List<Integer> imageViews = new ArrayList<Integer>();
List<Integer> images = new ArrayList<Integer>();

public void clearimg()
    {
        str1.setImageResource(android.R.color.transparent);
        str2.setImageResource(android.R.color.transparent);
        str3.setImageResource(android.R.color.transparent);
        str4.setImageResource(android.R.color.transparent);
        str5.setImageResource(android.R.color.transparent);
        str6.setImageResource(android.R.color.transparent);
        str7.setImageResource(android.R.color.transparent);
        str8.setImageResource(android.R.color.transparent);
        str9.setImageResource(android.R.color.transparent);
        str10.setImageResource(android.R.color.transparent);
    }

public void viewadd()
{
    imageViews.add(R.id.star1);
    imageViews.add(R.id.star2);
    imageViews.add(R.id.star3);
    imageViews.add(R.id.star4);
    imageViews.add(R.id.star5);
    imageViews.add(R.id.star6);
    imageViews.add(R.id.star7);
    imageViews.add(R.id.star8);
    imageViews.add(R.id.star9);
    imageViews.add(R.id.star10);
}


public void imageadd()
{
    images.add(R.drawable.star1);
    images.add(R.drawable.star2);
    images.add(R.drawable.star3);
    images.add(R.drawable.star4);
    images.add(R.drawable.star5);
    images.add(R.drawable.star6);
    images.add(R.drawable.star7);
    images.add(R.drawable.star8);
    images.add(R.drawable.star9);
    images.add(R.drawable.star10);
}

View.OnClickListener tapHandler = new View.OnClickListener() 
    {

        @Override
        public void onClick(View v) 
        {
            // TODO Auto-generated method stub
               clearimg();
             imageadd();
                viewadd();


               Random rng = new Random(); 
                List<Integer> generated = new ArrayList<Integer>();
                for (int i = 0; i < 10; i++)
                {
                  while(true)
                    {

                      Integer next = rng.nextInt(imageViews.size()) ;
                      if (!generated.contains(next))
                        {
                         generated.add(next);
                         ImageView iv = (ImageView)findViewById(imageViews.get(next));
                         iv.setImageResource(images.get(next));
                         images.remove(next);
                         imageViews.remove(next);
                         break;
                        }
                    }



                }


          }
    };

Answer 1

 List<Integer> views = new ArrayList<Integer>();
 List<Integer> images = new ArrayList<Integer>();
 //populate your lists

您应该从列表中删除已使用的资源。这是一个例子。在你的时间：

 Integer next = rng.nextInt(views.size()) ;
 if (!generated.contains(next))
 {
    generated.add(next);
    ImageView iv = (ImageView)findViewById(views.get(next));
    iv.setImageResource(images.get(next));
    images.remove(next);
    views.remove(next);
    break;
 }

如何使用此代码重复随机位置和图像的处理
