java – Show Custom emoticon in Android Keyboard-ThrowExceptions

Exception or error:

I have been trying for the last 3 days to show a graphical custom emoticon in the default android message view. I have successfully shown my custom emoticons in place of keys. Now the problem is that I am trying to show a drawable in spanable string builder. But the drawable just does not appear on the keyboard. Here is the code so far:

     SpannableString ss = new SpannableString(" "); 
                    Drawable d = getResources().getDrawable(R.drawable.a); 
                    d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight()); 
//                  ImageSpan span = new ImageSpan(d, ImageSpan.ALIGN_BASELINE); 
                    ImageSpan span = new ImageSpan(d);
//                  ss.setSpan(span, 0, 1, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);

                    mComposing.append(":");
                    mComposing.setSpan(new ImageSpan(d), 0,1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
                    getCurrentInputConnection().commitText(mComposing, 1);

I have tried different methods to somehow fit the drawable but it just wont show on the default message view of android. Any help would be highly appreciated.

Maybe you could use:

String txt = "<img src=\"" + resourceID + "\"/>"; to generate an HTML tag and after that

Spanned spanned = Html.fromHtml(txt, emojiGetter, null);
editTextObj = setText(spanned,BufferType.SPANNABLE);

where emojiGetter is

private ImageGetter emojiGetter = new ImageGetter() {
    public Drawable getDrawable(String source){
        int id = getResources().getIdentifier(source, "drawable", context.getPackageName());

        Drawable emoji = getResources().getDrawable(id);
        int w = (int)emoji.getIntrinsicWidth() ;
        int h = (int)emoji.getIntrinsicHeight() ;
        emoji.setBounds(0, 0, w, h);
        return emoji;
    }
};

It works fine for me. I’ve created a CustomEditText component to simplify this conversion.

i have achieved it doing like this

 ImageGetter imageGetter = new ImageGetter() 
                {
                    public Drawable getDrawable(String source) {
                        Drawable d = getResources().getDrawable(R.drawable.e041);
                        d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
                        return d;
                    }
                };

                Spanned cs = Html.fromHtml("<img src='" + getResources().getDrawable(R.drawable.e041) + "'/>", imageGetter, null);

             getCurrentInputConnection().commitText(cs, 1); 

//but it override the last entered text see my question here
