I know I should use the Html.fromHtml(String source, Html.ImageGetter imageGetter, Html.TagHandler tagHandler)

But I don’t know how to get the ImageGetter, Can anyone help?

Answer 1

This worked for me,

Implementing a ImageGetter is straight and simple; you pass an ImageGetter object to be use to fetch the images that later will be use to fill the placeholders. In order to fetch the images the ImageGetter object must implement the getDrawable method. The getDrawable method must return the Drawable object that will fill the placeholder; but, if null is returned the generic image placeholder will be used instead (see implementation below).

For ImageGetter you need to override the method below:

public Drawable getDrawable (String  source)

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 = (Drawable) myActivity.this.getResources().getDrawable(path);
     drawFromPath.setBounds(0, 0, drawFromPath.getIntrinsicWidth(), drawFromPath.getIntrinsicHeight());
     return drawFromPath;
    }
}, null));
