Convert Drawable To A Specific String

I have a chat app which I want to extend with emoticons. This code is used to insert a smilie in the text: Spanned cs = Html.fromHtml('', imageGet

Solution 1:

if you want to replace your emoticons try this:

EditTextet=newEditText(this);
et.setTextSize(24);
et.setHint("this view shows \":)\" as an emoticon, try to type \":)\" somewhere");
finalBitmapsmile= BitmapFactory.decodeResource(getResources(), R.drawable.emo_im_happy);
finalPatternpattern= Pattern.compile(":\\)");
TextWatcherwatcher=newTextWatcher() {
booleanfastReplace=true; 
    @OverridepublicvoidonTextChanged(CharSequence s, int start, int before, int count) {
        //Log.d(TAG, "onTextChanged " + start + " " + before + " " + count);if (fastReplace) {
            if (start > 0 && count > 0) {
                Stringsub= s.subSequence(start - 1, start + 1).toString();
                if (sub.equals(":)")) {
                    Spannablespannable= (Spannable) s;
                    ImageSpansmileSpan=newImageSpan(smile);
                    spannable.setSpan(smileSpan, start-1, start+1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
                }
            }
        } else {
            Spannablespannable= (Spannable) s;
            Matchermatcher= pattern.matcher(s);
            while (matcher.find()) {
                intmstart= matcher.start();
                intmend= matcher.end();
                ImageSpan[] spans = spannable.getSpans(mstart, mend, ImageSpan.class);
                Log.d(TAG, "onTextChanged " + mstart + " " + mend + " " + spans.length);
                if (spans.length == 0) {
                    ImageSpansmileSpan=newImageSpan(smile);
                    spannable.setSpan(smileSpan, mstart, mend, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
                }
            }
        }
        Log.d(TAG, "onTextChanged " + s);
    }

    @OverridepublicvoidbeforeTextChanged(CharSequence s, int start, int count, int after) {
    }

    @OverridepublicvoidafterTextChanged(Editable s) {
        Log.d(TAG, "afterTextChanged " + s);
    }
};
et.addTextChangedListener(watcher );

setContentView(et);

here if fastReplace == true you don't have to scan the whole text but it's only minimal implementation: works only if you type ")" right after typed ":", if fastReplace == false it replaces every occurrence of ":)" with a smiley but it has to scan the whole text so it's a bit slower when text is quite large
