設定指定名字的圖片；

int imgId = getResources().getIdentifier(imgName, "drawable", getPackageName());   //imgName為圖片名稱；
imageView.setImageResource(imgId);

所以當有一組圖片要顯示時(圖片以a1、a2、a3……命名）可以用for迴圈：

int[] imgs = new int[7];
for(int i=0; i<imgs.size(); i++)
{
    imgs[i] = getResources().getIdentifier("a"+i, "drawable"
 
, getPackageName());
}

從MyEclipse伺服器上下載圖片；

    private Bitmap getImage(String imgPath)
    {
        URL url = null;
        Bitmap bitmap = null;
        InputStream input = null;
        HttpURLConnection httpCon = null;
        //伺服器地址+專案名+圖片的路徑；http://192.168.18.145:8080/Order/images/a.png (images/a.png是在伺服器的WebRoot資料夾下）;
 

        url = new URL(Content.path + imgPath);  
        httpCon = (HttpURLConnection) url.openConnection();
        httpCon.setConnectTimeout(5000);  //設定超時時間；
         System.out.println("=============");
        if(httpCon.getResponseCode() == 200)
        {
            System.out.println("----------="
 
);
            input = httpCon.getInputStream();
            bitmap = BitmapFactory.decodeStream(input);
            System.out.println("=====" + bitmap);
        }
        //獲取失敗的話，就顯示本地的任意一張圖片；
        else
        {
            bitmap = BitmapFactory.decodeResource(this.getResources(), R.drawable.dish_no_image);
        }

        if(input != null)
        {
            input.close();              
        }
        if(httpCon != null)
        {
            httpCon.disconnect();
        }
    return bitmap;
    }
