我得到了这个json和created_time值显示整数格式的时间而不是时间格式,但我希望这个created_time以适当的格式.如何以正确的格式获取created_time？

"filter"=>"Normal",
"created_time"=>"1421677966",
  "link"=>"http://instagram.com/p/yCfw5sKorK/",
  "likes"=>{
    "count"=>1,
    "data"=>[
      {
        "username"=>"nikhil.thombare",
        "profile_picture"=>"https://instagramimages-a.akamaihd.net/profiles/anonymousUser.jpg",
        "id"=>"1651917721",
        "full_name"=>"Nikhil Narendra Thombare"
      }
    ]

我正在使用9图像视图我想要随机设置图像到imageview,当我点击刷新按钮,但我尝试这样它是为图像的随机分配工作,但它一次在两个(或)三个imageview中重复相同的图像.我的代码中的问题在哪里..

 final int[] imageViews = {
            R.id.imgview11, R.id.imgview12, R.id.imgview13, 
            R.id.imgview21, R.id.imgview22, R.id.imgview23, 
            R.id.imgview31, R.id.imgview32, R.id.imgview33 };

    final int[] images = {
            R.drawable.i1, R.drawable.i2, R.drawable.i3, 
            R.drawable.i4, R.drawable.i5, R.drawable.i6, 
            R.drawable.i7, R.drawable.i8, R.drawable.empty };

    final ImageButton shuffle = (ImageButton) findViewById(R.id.new_puzzle); 
    shuffle.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {        
            Random generator = new Random();
            //int n = 9;
            //n = generator.nextInt(n);
            //Random random = new Random(System.currentTimeMillis());
            for(int v : imageViews) {
                ImageView iv = (ImageView)findViewById(v);
                iv.setImageResource(images[generator.nextInt(images.length - 1)]);
            }
        }
    });      

我不想重复,一个图像仅适用于一个imageview ..
