Loading images in galleryview

I want to load images in gallery view in a manner that once images is load than after when user scrolls, want to show loading indicator and than after new image will be display. in my below code it takes all the data(including images) and display.

here is my code:

ProductDetailsActivity.java

public class ProductsDetailActivity extends BaseActivity implements
        OnClickListener, OnItemSelectedListener {
    Gallery gallery;
    TextView prod_descri, productTitle1, productTitle2;
    ImageAdapter imageAdapter;
    ImageView leftArrow, rightArrow;
    private int selectedImagePosition = 0;
    private List<Drawable> drawables;
    String title, url, title1;
    Bundle b;
    Products product;
    ProductDetails pDetails;
    ArrayList<ProductDetails> productList;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.products_details);
        init();

        setTitle(getResources().getString(R.string.title_product));
        b = getIntent().getExtras();
        product = (Products) b.getSerializable("product");
        if (b != null) {
            if (Global.isNetworkAvailable(ProductsDetailActivity.this)) {
                new ProductAsyncTask().execute(Constants.url,

Solution

  • Download Universal Image Loader from https://github.com/nostra13/Android-Universal-Image-Loader.

    Add the jar file to your libs folder of your project

    Note: The below display's image by downloading images from internet. You can also provide path of images from your sdcard folder.

    Universal Image Loader is a improves version of Lazy Loading. Loads Images asynchronously. You can cache images in your sdcard or phone memory if your are downloading image from internet
