我使用 ImageDownloader 类来从服务器映像和获得使用一个ArrayList这些图像的链接。下载图片后，我设置的图像作为布局背景。所有的工作，但我希望有一个具体的的时间间隔后改变这些图像，并设置为背景不同的图像。我已经经历了很多帖子了这里，但没有得到我想要的。正如我在ArrayList中的所有图片的链接，所以我怎么能设置一个计时器来改变图像，从的ArrayList 。它到来总是让我在指数为零连我都设置一个计时器，但同样的图像再次显示？请帮我，如果有人有任何code为例，看看我的code有什么改变呢？

 最后ImagesSerialized项目;
最后ImageView的bgImage =（ImageView的）findViewById（R.id.image）;

        控制=（控制器）getApplicationContext（）;
        名单=（ArrayList中＆LT; ImagesSerialized＆GT;）control.Table_Images.GetData（）;

         的for（int i = 0; I＆LT;则为list.size（）;我++）

解决方案

我不知道 ImageLoader的分量，但在一个视图调度计时器是很容易在Android中。 （没有任何额外的对象）

 最后ImageView的bgImage =（ImageView的）findViewById（R.id.image）;

...

新的Runnable（）{
    INT updateInterval = 1000; // =1秒

    @覆盖
    公共无效的run（）{

        //任何code肚里，这里将被执行每一个updateInterval
        //这里改变你的背景

        bgImage.postDelayed（这一点，updateInterval）;
    }
}。跑（）;
 

你愿意，可以改变这个模板，假设我想停止这个定时器，用于这个目的，我必须添加一个stop方法我同步的可运行（此停车方法行为，并不会导致不一致的计时器内codeS）：

 的Runnable myRunnable =新的Runnable（）{
    INT updateInterval = 1000; // =1秒
    布尔停止= FALSE;

    公共无效停止（）{
        this.stop = TRUE;
    }

    @覆盖
    公共无效的run（）{

        //任何code肚里，这里将被执行每一个updateInterval
        //这里改变你的背景

        如果（！停止）{
            bgImage.postDelayed（这一点，updateInterval）;
        }
    }
}。跑（）;
 

现在我可以通过 myRunnable.stop（）停止;

编辑： 你应该重复你的网址阵列，并通过其中的一个到你的下载器。它可以通过这个片段code来实现：

  INT ARRAYSIZE =则为list.size（）;

新的Runnable（）{
    INT CURRENTINDEX = 0;
    INT updateInterval = 1000; // =1秒

    @覆盖
    公共无效的run（）{

        CURRENTINDEX + = 1;
        如果（CURRENTINDEX == ARRAYSIZE）{
            CURRENTINDEX = 0;
        }

        项目= list.get（CURRENTINDEX）;
        downloader.download（item.imageurl（），bgImage）;

        bgImage.postDelayed（这一点，updateInterval）;
    }
}。跑（）;
 

I am using ImageDownloader class to get images from server and getting these images links using an ArrayList. After downloading the Image I am setting the Image as background of the layout. All is working but I want to change these Images after a specific time interval and set as background different images. I have gone through many posts here but didn't get what I want. As I have all Images links in ArrayList, so how can I set a timer to change the images, coming from that ArrayList.It always show me the first Image at index zero even I have set a timer but the same Image is showing again? Please help me if someone has any code example and see my code what to change there?

final ImagesSerialized item;
final ImageView bgImage=(ImageView) findViewById(R.id.image);
 ArrayList<ImagesSerialized> list;
        control = (Controller) getApplicationContext();
        list = (ArrayList<ImagesSerialized>) control.Table_Images.GetData();

         for(int i=0; i<list.size(); i++)
         {
         item = list.get(i);
         }




         downloader = new ImageDownloader();
         downloader.download(item.imageurl(), bgImage);

I do not know about ImageLoader component but scheduling a timer on a view is quite easy in Android.(Without any additional Object)

final ImageView bgImage=(ImageView) findViewById(R.id.image);

...

new Runnable() {
    int updateInterval = 1000; //=one second

    @Override
    public void run() {

        // Any code which goes here will be executed every 'updateInterval'
        // change your background here            

        bgImage.postDelayed(this, updateInterval);
    }
}.run();

You can change this template as you wish, suppose I want to stop this timer, for this purpose I have to add a stop method to my runnable(This stop method acts synchronized and do not cause inconsistency in timer inner codes):

Runnable myRunnable = new Runnable() {
    int updateInterval = 1000; //=one second
    boolean stop = false;

    public void stop() {
        this.stop = true;
    }    

    @Override
    public void run() {

        // Any code which goes here will be executed every 'updateInterval'
        // change your background here            

        if(!stop) {
            bgImage.postDelayed(this, updateInterval);
        }
    }
}.run();

Now I can stop it by myRunnable.stop();

EDIT : You should iterate your array of URLs and pass one of them to your downloader. It can be accomplished by this snippet code:

int arraySize = list.size();

new Runnable() {
    int currentIndex = 0;
    int updateInterval = 1000; //=one second

    @Override
    public void run() {

        currentIndex += 1;
        if(currentIndex == arraySize){
            currentIndex = 0;
        }

        item = list.get(currentIndex);       
        downloader.download(item.imageurl(), bgImage);            

        bgImage.postDelayed(this, updateInterval);
    }
}.run();
