How To Set Image Button Resource From Web Url In Android?

I have an image button and would like to set background image from internet URL. I don't want to save background picture into SD card instead my image button's image needs to be UR

Solution 1:

Never tried this but hope fully this will work with you

private Drawable ImageOperations(Context ctx, String url, String saveFilename) {
    try {
        InputStream is = (InputStream) this.fetch(url);
        Drawable d = Drawable.createFromStream(is, saveFilename);
        return d;
    } catch (MalformedURLException e) {
        e.printStackTrace();
        returnnull;
    } catch (IOException e) {
        e.printStackTrace();
        returnnull;
    }
}

and for image view

ImageView IV= (ImageView)findViewById(R.id.imageId);      
Drawabledrw= ImageOperations(this,url,filename)
IV.setBackgroundDrawable(drw)

get URL

public Object fetch(String address)throws MalformedURLException,IOException {

    URLurl=newURL(address);
    Objectcontent= url.getContent();
    return content;
}

Solution 2:

First you have to download your Image as Drawable: Android Drawable Images from URL

and after that set it as background drawable

button.setBackgroundDrawable(drawable)

Solution 3:

Try this

        Bitmap bitmap;
classloadImageextendsAsyncTask<Void , Void, Void>{
    @OverrideprotectedvoidonPreExecute() {
        super.onPreExecute();
    }
    @Overrideprotected Void doInBackground(Void... params) {
        URLurl=newURL(stringURL);
        URIuri=newURI(url.getProtocol(), url.getHost(),
                url.getPath(), url.getQuery(), null);
        HttpURLConnectionconnection= (HttpURLConnection) uri
                .toURL().openConnection();
        connection.setDoInput(true);
        connection.connect();
        InputStreaminput= connection.getInputStream();
        ByteArrayOutputStreambyteBuffer=newByteArrayOutputStream();

        intbufferSize=1024;
        byte[] buffer = newbyte[bufferSize];
        intlen=0;
        while ((len = input.read(buffer)) != -1) {
            byteBuffer.write(buffer, 0, len);
        }
        byte[] img = byteBuffer.toByteArray();
        byteBuffer.flush();
        byteBuffer.close();
        input.close();
        bitmap = BitmapFactory.decodeByteArray(img, 0, img.length);
        returnnull;
    }
    @OverrideprotectedvoidonPostExecute(Void result) {
        super.onPostExecute(result);
        ImageButtonimage_btn= (ImageButton)findViewById(R.id.your_image_button_id);
        image_btn.setImageBitmap(bitmap);
    }
}
