I have a JSON
string, say a name and a Url . I need to extract name into the TextView
and extract and display image in ImageView
.
Below is the code for above scenario.
public static final String JSON_STRING="{\"WebImages\":{\"Imagename\":\"image_name\",\"imageurl\":http://www.example.com/image/example.png}}";
I need to display the name in TextView
which I created, and fetch the image from that url and display in the Imageview
.
First of all use Gson to parse Json and get url as a String, then you can use UniversalImageLoader library (it does the async image download and very easy to use) https://github.com/nostra13/Android-Universal-Image-Loader
static public DisplayImageOptions options= new DisplayImageOptions.Builder().cacheOnDisk(true).cacheInMemory(true).build();
imageLoader.displayImage(imgUrl, ivImage, options, new ImageLoadingListener() {
public void onLoadingStarted(String imageUri, View view) {
((ImageView)view).setImageResource(R.drawable.nofoto);
}
public void onLoadingFailed(String imageUri, View view, FailReason failReason) {
((ImageView)view).setImageResource(R.drawable.nofoto);
}
public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
}
public void onLoadingCancelled(String imageUri, View view) {
}
});
