android - Is there any way to insert an ImageSpan in a TextView without disrupting the text?

Question

It seems that in order to add an ImageSpan to a Spannable in Android, I have to actually replace some text with the Image. For example:

Spannable span = new SpannableString("Foo imageplace Bar!");
Drawable android = context.getResources().getDrawable(R.drawable.android);
android.setBounds(0, 0, 32,32);
ImageSpan image = new ImageSpan(android, ImageSpan.ALIGN_BASELINE);
span.setSpan(image, 4, 14, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);

This will replace "imageplace" with the image. Because I'm dealing with complex multi-span text and reiteration, it's a bit of a headache to insert meaningless text at each place I want the android icon. But it looks like if start and end of span are the same, the image won't be included. Is there any way around this?

Answer 1

Maybe you can add an additional space to be replaced by the ImageSpan. For example,

Spannable span = new SpannableString("Foo  imageplace Bar!");
Drawable android = context.getResources().getDrawable(R.drawable.android);
android.setBounds(0, 0, 32,32);
ImageSpan image = new ImageSpan(android, ImageSpan.ALIGN_BASELINE);
span.setSpan(image, 3, 4, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);

And you will find the image replace the additional space without disrupting the text.
