android - How to display code snippet in textview? -


i'm trying display code snippet in textview.but cannot make long text line auto scrollable horizontally in textview.

code:

    textview code = new textview(getactivity());     tablerow.layoutparams paramsexample = new tablerow.layoutparams(tablerow.layoutparams.match_parent,tablerow.layoutparams.wrap_content);     code.setbackgroundcolor(getresources().getcolor(android.r.color.black));     code.setpadding(5, 5, 5, 5);     code.settextcolor(getresources().getcolor(android.r.color.white));     code.settextsize(typedvalue.complex_unit_sp,12);     code.setclickable(true);     code.setlayoutparams(paramsexample);     setcode(code, r.raw.codesnippet);     ll.addview(code);

i'm creating textview in fragment.fragment_layout.xml:

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:id="@+id/fragment_ll"     android:orientation="vertical">  </linearlayout>

and starting fragment in activity in coordinatorlayout > nestedscrollview > linearlayout(fragment container)

each one's width size "match parent"

this setcode method:

   public void setcode(textview tv, int rawid) {     resources res = getresources();     bufferedreader input = new bufferedreader(new inputstreamreader(             res.openrawresource(rawid)));     stringbuffer sb = new stringbuffer();     try {         string line;         while ((line = input.readline()) != null) {             sb.append(line);         }     } catch (ioexception e) {         e.printstacktrace();     } {         try {             input.close();         } catch (ioexception e) {             e.printstacktrace();         }     }     spanned spannedcode = html.fromhtml(sb.tostring());     tv.settext(spannedcode); }

i got code snippet (codesnippet.txt) vim:tohtml.

but not scroll horizontally.what should make auto scrollable horizontally webview ?

output above code:
enter image description here

after horizontalscrollview , code.sethorizontallyscrolling(true):

horizontal scrolling works fine in single line.i need display code snippet block.

your textview should inside horizontalscrollview following:

<horizontalscrollview      android:layout_width="fill_parent"      android:layout_height="fill_parent">      <textview android:layout_width="40dp"         android:layout_height="wrap_content"         android:scrollhorizontally="true"         android:text="horizontal scroll view"/>  </horizontalscrollview>
