Question

I’m trying to load a remote image from the server using the following code:

imageViewClient = (ImageView) findViewById(R.id.imageViewClient);
try 
{
    URL thumb_u = new URL(c.getImage());
    Drawable thumb_d = Drawable.createFromStream(thumb_u.openStream(), "src");
    imageViewClient.setImageDrawable(thumb_d);                      

}
catch (Exception e) 
{

}

The image is showing fine but when I put the code into a new thread, the image is not loaded.

The code is:

new Thread() 
{
    @Override
    public void run()
    {
            //** Set imageview url
            try {
                URL thumb_u = new URL(c.getImage());
                Drawable thumb_d = Drawable.createFromStream(
                    thumb_u.openStream(), "src");

                imageViewClient.setImageDrawable(thumb_d);                      

            }
            catch (Exception e) {

            }

    }
}.start();

The image does not load, why not?

you will need to use Activity.runOnUiThread for changing from background thread as :

 @Override
  public void run() {
     //** Set imageview url
     try {
        URL thumb_u = new URL(c.getImage());
         Drawable thumb_d = Drawable.createFromStream(
                              thumb_u.openStream(), "src");                      

        Your_current_Activity.this.runOnUiThread(new Runnable() {
        public void run() {
         // Chnage imageView bg here
        imageViewClient.setImageDrawable(thumb_d); 
        }
    });
       }
     catch (Exception e) {

    }
