how to add multiple sytleSpan in single editText?

Question

I'm working with with editText and buttons and layout contains four buttons

1. btnBold
2. btnItalic
3. btnStrike
4. btnUnderline

and one editText etDescription

Now, here I'm styling my editText's selected text by clicking on buttons

with using this code

CharacterStyle styleBold, styleItalic, styleUnderline, styleStrike;

 styleBold = new StyleSpan(Typeface.BOLD);
 styleItalic = new StyleSpan(Typeface.ITALIC);
 styleUnderline = new UnderlineSpan();
 styleStrike = new StrikethroughSpan();


 @Override
    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.btnItalic:
                makeIt(styleItalic);
                break;

            case R.id.btnBold:
                makeIt(styleBold);
                break;

            case R.id.btnUnderline:
                makeIt(styleUnderline);
                break;
            case R.id.btnStrike:
                makeIt(styleStrike);
                break;
        }
    }

    private void makeIt(CharacterStyle characterStyle) {
        String wholeTextUnder = etDescription.getText().toString();
        int startu = etDescription.getSelectionStart();
        int endu = etDescription.getSelectionEnd();

        SpannableStringBuilder sbu = new SpannableStringBuilder(wholeTextUnder);

        sbu.setSpan(characterStyle, startu, endu, 0);
        etDescription.setText(sbu);
    }

It's giving my whole editText a single style

Like when i select text 1-10 and then make it's bold it works!

but, when i select other text then make it some other like italic, strike, underline then pervious text become normal and new changes successfully.

I want that perivous text will also stay same

Waiting for answer!

Thanks in advance!!

Happy coding!

Your problem is when you call String wholeTextUnder = etDescription.getText().toString(); You already change it to String it means any Span you set will be clear. Try this.

private void makeIt(CharacterStyle characterStyle) {
    CharSequence wholeTextUnder = etDescription.getText();
    int startu = etDescription.getSelectionStart();
    int endu = etDescription.getSelectionEnd();

    SpannableStringBuilder sbu = new SpannableStringBuilder(wholeTextUnder);

    sbu.setSpan(characterStyle, startu, endu, 0);
    etDescription.setText(sbu);
}
