android - Html.ImageGetter

Question

Can any one help me out how to use Html.ImageGetter to dispaly images using html image src tag ? and example or good tutorial

Answer 1

To get images from the application resources first in the text file one inserts an html image tag like this:

<img src="my_image">

Note that "my_image" is just a name of a drawable not a path. Then use this code to diplay the text with images in TextView

myTextView.setText(Html.fromHtml(myText, new ImageGetter() {
   @Override public Drawable getDrawable(String source) {
      Drawable drawFromPath;
      int path =
            myActivity.this.getResources().getIdentifier(source, "drawable",
               "com.package...");
      drawFromPath = myActivity.this.getResources().getDrawable(path);
      drawFromPath.setBounds(0, 0, drawFromPath.getIntrinsicWidth(),
         drawFromPath.getIntrinsicHeight());
      return drawFromPath;
   }
}, null));

If the source in the img tag is misspelled the applicaiton will crash because the method will fail to find the drawable, so more code can be added to prevent this...
