I have SpannedText
in EditText
and I am replacing text with smiles for example cool replaced with smile. But when I am pressing Backspace on android phone (Nexus 5 kitkat 4.4.4) it shows "(Smile)cool" then it deletes the letters at last the smile itself. But on Genymotion emulator it works as needed. What is wrong with my code?
This code is in for
Drawable d = Drawable.createFromStream(ims, null);
Bitmap b = ((BitmapDrawable)d).getBitmap();
int spanSmileHeight = (displayHeight>displayWidth) ? ((int) ((double) displayHeight/25)) : ((int) ((double) displayWidth/25));
int spanSmileWidth = ((int) ((double) spanSmileHeight/b.getHeight())*b.getWidth())+15;
Bitmap bitmapResized = Bitmap.createScaledBitmap(b, spanSmileWidth, spanSmileHeight, false);
Drawable sd = new BitmapDrawable(getResources(), bitmapResized);
sd.setBounds(0, 0, spanSmileWidth, spanSmileHeight);
addPattern(emoticons, smileyCode, sd);
...
ImageView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
int start = Math.max(message.getSelectionStart(), 0);
int end = Math.max(message.getSelectionEnd(), 0);
message.getText().replace(Math.min(start, end), Math.max(start, end),
smileyCode, 0, smileyCode.length());
message.setText(getSmiledText(view.getContext(), message.getText()));
message.setSelection(start + smileyCode.length());
and this
public static boolean addSmiles(Context context, Spannable spannable) {
boolean hasChanges = false;
for (Map.Entry<Pattern, Drawable> entry : emoticons.entrySet()) {
Matcher matcher = entry.getKey().matcher(spannable);
while (matcher.find()) {
boolean set = true;
for (ImageSpan span : spannable.getSpans(matcher.start(),
matcher.end(), ImageSpan.class))
if (spannable.getSpanStart(span) >= matcher.start()
&& spannable.getSpanEnd(span) <= matcher.end())
spannable.removeSpan(span);
else {
set = false;
break;
}
if (set) {
hasChanges = true;
spannable.setSpan(new ImageSpan(entry.getValue(), ImageSpan.ALIGN_BOTTOM),
matcher.start(), matcher.end(),
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
}
}
}
return hasChanges;
}
public static Spannable getSmiledText(Context context, CharSequence text) {
Spannable spannable = spannableFactory.newSpannable(text);
addSmiles(context, spannable);
return spannable;
}
Before bacspace
After backspace(of virtual keyobard) pressed

I have found a way how to prevent this. If we change targetSDK to 15 then smiles are deleted succesfully.
