Two extra lines added to edit text when retrieving html String

Question

I save my formatted edit text in sqlite database in html then after retrieving it two extra lines are added to the edit text

So I started like so:-

 edt.setText(Html.fromHtml("<b>"+myString+"</b>"));//making it bold
 Editable e = edt.getText();//convert to Editable
 String text = Html.toHtml(e);//convert to String

Then after I inserted text into the database .I retrieved it back to edt this way:-

Spanned sp = Html.fromHtml(text);//convert text to spanned
edt.setText(sp);//setting to the edittext

It was retrieved successfully however 2 extra lines where added to edt at the end of text each time why you think that occurs?.

try this

edt.setText(Html.fromHtml("<b>"+myString+"</b>"));//making it bold
Editable e = edt.getText();//convert to Editable
/* String text = Html.toHtml(e);//convert to String

Spanned sp = Html.fromHtml(text);  //convert text to spanned */
edt.setText(e);//setting to the edittext

this problem is Html.toHtml() and Html.fromHtml() adding escape word "\n". – 배준모 Jun 19 '17 at 09:01
Do you mean edt should be set from Editable instead of spanned ? this is the only difference I see from my code – Omar Boshra Jun 19 '17 at 09:03
I think It maybe the html extra line breaks – Omar Boshra Jun 19 '17 at 09:04
in Html.java you can find withinDiv(StringBuilder out, Spanned text, int start, int end, int option){ ........ out.append("\n"); ....} – 배준모 Jun 19 '17 at 09:15

I finally found a solution using code from an answer in this question Remove extra line breaks after Html.fromHtml() .Its all about removing extra html whitspaces but using it for spannable String like so :-

Spanned sp = Html.fromHtml(subnote);

int h = sp.length();

// loop back to the first non-whitespace character

while(--h >= 0 && Character.isWhitespace(sp.charAt(h))) {
}

sp= (Spanned) sp.subSequence(0, h+1);



edt.setText(sp);
