Question

I’m trying to download an image, and create an ImageView dynamically and add it to my layout, but it won’t display the image. Here is my code:

ImageView image = new ImageView(this);
LinearLayout.LayoutParams vp = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
image.setLayoutParams(vp);
image.setScaleType(ImageView.ScaleType.CENTER_CROP);
image.setMaxHeight(50);
image.setMaxWidth(50);
image.setImageDrawable(avatar);
theLayout.addView(image);

maybe I need to refresh the layout after I add the ImageView? How do you “refresh”?

Answer 1

Try the following code, and you will not need to refresh. Put your image url into the inputurl variable.

InputStream is = null;
String inputurl = " Enter url of ur image ";
try {
        URL url = new URL(inputurl);
        Object content = url.getContent();
        is = (InputStream) content;
        avatar = Drawable.createFromStream(is,"src");
} catch (MalformedURLException e) {
        e.printStackTrace();
} catch (IOException e) {
        e.printStackTrace();
}

ImageView image = new ImageView(this);
LinearLayout.LayoutParams vp = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
image.setLayoutParams(vp);
image.setScaleType(ImageView.ScaleType.CENTER_CROP);
image.setMaxHeight(50);
image.setMaxWidth(50);
image.setImageDrawable(avatar);
theLayout.addView(image);
