Removing Style From Selected Text In Edittext

My app should allow users to style inputted or selected text in an Edittext. Some of these styles are Underline, Strike through, Bold and Italic. They are easily added but I don't

Solution 1:

I think this class solve your problem.

publicclassStyleSpanRemover {

    publicvoidRemoveOne(Spannable spannable,
                          int startSelection, int endSelection, Class<?> style){

        ArrayList<SpanParts> spansParts = getSpanParts(spannable, startSelection, endSelection);
        removeOneSpan(spannable, startSelection, endSelection, style);
        restoreSpans(spannable, spansParts);
    }

    publicvoidRemoveStyle(Spannable spannable,
              int startSelection, int endSelection, int styleToRemove){

        ArrayList<SpanParts> spansParts = getSpanParts(spannable, startSelection, endSelection);
        removeStyleSpan(spannable, startSelection, endSelection, styleToRemove);
        restoreSpans(spannable, spansParts);
    }

    publicvoidRemoveAll(Spannable spannable, int startSelection, int endSelection){

        ArrayList<SpanParts> spansParts = getSpanParts(spannable, startSelection, endSelection);
        removeAllSpans(spannable, startSelection, endSelection);
        restoreSpans(spannable, spansParts);
    }

    protectedvoidrestoreSpans(Spannable spannable, ArrayList<SpanParts> spansParts){

        for (SpanParts spanParts : spansParts) {
            if(spanParts.part1.canAplly())
                spannable.setSpan(spanParts.part1.span, spanParts.part1.start,
                                  spanParts.part1.end,spanParts.span_flag);
            if(spanParts.part2.canAplly())
                spannable.setSpan(spanParts.part2.span, spanParts.part2.start,
                                  spanParts.part2.end, spanParts.span_flag);
        }
    }

    protectedvoidremoveAllSpans(Spannable spannable,int startSelection, int endSelection) {

        Object spansToRemove[] = spannable.getSpans(startSelection, endSelection, Object.class);
        for(Object span: spansToRemove){
            if(span instanceof CharacterStyle)
                spannable.removeSpan(span);
        }
    }

    protectedvoidremoveOneSpan(Spannable spannable,int startSelection, int endSelection,
                           Class<?> style) {

        CharacterStyle spansToRemove[] = spannable.getSpans(startSelection, endSelection, CharacterStyle.class);
        for(CharacterStyle span: spansToRemove){
            if(span.getUnderlying().getClass() == style )
                spannable.removeSpan(span);
        }
    }

    protectedvoidremoveStyleSpan(Spannable spannable, int startSelection,
        int endSelection, int styleToRemove) {

        MetricAffectingSpan spans[] = spannable.getSpans(startSelection, endSelection, MetricAffectingSpan.class);

            intstylesApplied=0;

            int spanStart;
            int spanEnd;
            int spanFlag;
            ObjectspanUnd= span.getUnderlying();
            if(spanUnd instanceof StyleSpan){
                spanFlag = spannable.getSpanFlags(spanUnd);
                stylesApplied = ((StyleSpan) spanUnd).getStyle();
                stylesToApply = stylesApplied & ~styleToRemove;

                spanStart = spannable.getSpanStart(span);
                spanEnd = spannable.getSpanEnd(span);
                if(spanEnd >= 0 && spanStart >= 0){
                    spannable.removeSpan(span);
                    spannable.setSpan(newStyleSpan(stylesToApply), spanStart, spanEnd,spanFlag);
                }
            }
        }
    }

    protected ArrayList<SpanParts> getSpanParts(Spannable spannable,
                                              int startSelection,int endSelection){

        ArrayList<SpanParts> spansParts = newArrayList<SpanParts>();
        Object spans[] = spannable.getSpans(startSelection, endSelection, Object.class);

                intspanStart= spannable.getSpanStart(span);
                intspanEnd= spannable.getSpanEnd(span);
                if(spanStart == startSelection && spanEnd == endSelection) continue;
                spanParts.span_flag = spannable.getSpanFlags(span);
                spanParts.part1.span = CharacterStyle.wrap((CharacterStyle) span);
                spanParts.part1.start = spanStart;
                spanParts.part1.end = startSelection;
                spanParts.part2.span = CharacterStyle.wrap((CharacterStyle) span);
                spanParts.part2.start = endSelection;

                spansParts.add(spanParts);
            }
        }
        return spansParts;
    }

    privateclassSpanParts{
        int span_flag;
        Part part1;
        Part part2;
        SpanParts() {
            part1 = newPart();
            part2 = newPart();

How to use:

int startSelection=editText.getSelectionStart();
int endSelection=editText.getSelectionEnd();
Spannable spannable = editText.getText();

StyleSpanRemover spanRemover = new StyleSpanRemover();
// to remove all styles
spanRemover.RemoveAll(spannable,startSelection,endSelection);
//to remove only StrikethroughSpan style use:
spanRemover.RemoveOne(spannable,startSelection,endSelection,StrikethroughSpan.class);
//to remove one StyleSpan use:
spanRemover.RemoveStyle(spannable,startSelection,endSelection,Typeface.BOLD)

Solution 2:

android.graphics.TYPEFACE.Default returns a Typeface, and the StyleSpan constructor takes an int as paramater.

Try using :

android.graphics.Typeface.DEFAULT.getStyle() 

instead of:

android.graphics.Typeface.DEFAULT

Solution 3:

I think this way below is the simplest but useful. It works for me.

Please try this code:

myEditText.setTypeface(Typeface.DEFAULT);
