生成bimaps与实例标题不同，每次？

问题描述

我需要生成的实例名称是不同的每一个thime如blocktitle1，blocktitle2，blocktitle3等。我已经把一些code键更改字符串变量头衔，但只是在前面加上标题，其中IM做一个新的位图将创建一个名为标题没有如blocktitle2的实例。

我会很greatfull在任何人都来帮忙。

 列表＆lt;嵌段＆GT;块=新的LinkedList＆lt;嵌段＆GT;（）;
 随机RND =新的随机（System.currentTimeMillis的（））; INT randomx = 400;
 公共block块;
 INT的blocknum = 10;
 字符串标题=blocktitle+的blocknum;
公共无效generateBlocks（）{          如果（的blocknum大于0）{              INT偏移= rnd.nextInt（400）+ 100; // 500是最大偏移，这是一个常数
              X + =偏移; // OFSET将是100和400之间              //我需要下面的块这个词被识别为一个字符串变量字符串标题
             块=新的块（BitmapFactory.de codeResource（getResources（），R.drawable.block），randomx，200）;
              的blocknum  -  = 1;
    }}
 

解决方案

试试这个：

 私有静态最后弦乐标题preFIX =的blocknum;
私有静态诠释titleNo = 0;
公共字符串getNextTitle（）{
    回到标题preFIX + titleNo ++;
}
 

i need the generated instance name to be different every thime eg blocktitle1, blocktitle2, blocktitle3 and so on. I have put some code to change the string variable "title" but just putting the word "Title" where im making a new bitmap will make the instance called "Title" not eg "blocktitle2".

I would be very greatfull in anyone were to help.

 List<Block> blocks = new LinkedList<Block>();
 Random rnd = new Random(System.currentTimeMillis());

 int randomx = 400;
 public Block block;
 int blocknum = 10;
 String Title = "blocktitle" + blocknum;


public void generateBlocks(){

          if(blocknum > 0){

              int offset = rnd.nextInt(400) + 100; //500 is the maximum offset, this is a constant
              x += offset;                         //ofset will be between 100 and 400

              // i need the word below "block" to be recognised as a String variable "String Title"
             block = new Block(BitmapFactory.decodeResource(getResources(), R.drawable.block), randomx, 200);
              blocknum -= 1;


    }

}

解决方案

Try this:

private static final String titlePrefix = "blocknum";
private static int titleNo = 0;
public String getNextTitle() {
    return titlePrefix + titleNo++;
}
