canvas - in android trying to create an image by taking the width and height of textview -


i have created layout , textview dynamically , set textview width value , hieght fill_parent.

while doing 

    tv = new textview(this);     tv.setlayoutparams(new layoutparams(500, layoutparams.wrap_content));     tv.settext("hello world how whats whats hows life oh great");     tv.settextcolor(color.black);     tv.setbackgroundcolor(color.transparent);     tv.settextsize(24);     ll.addview(tv);     this.setcontentview(ll);

its showing content nicely , wrapping correctly

hello world how whats whats hows life oh great

but when try extract textview width , height , try create image of same width , same height, generating smaller width image cutting correctly word y partially.

    bitmap = bitmap.createbitmap(tv.getwidth(),tv.getheight(),config.rgb_565);      canvas=new canvas(bitmap);     canvas.drawargb(255,0,255,0);             paint.setstyle(style.fill);     paint.setcolor(color.blue);     paint.setantialias(true);     paint.settypeface(typeface.serif);     paint.settextsize((int) 24);             canvas.drawtext(tv.gettext().tostring().substring(0,44),0,27, paint);     canvas.drawtext(tv.gettext().tostring().substring(tv.getlayout().getlinestart(1),tv.getlayout().getlinestart(2)),0,48, paint);     canvas.drawtext(tv.gettext().tostring().substring(tv.getlayout().getlinestart(2),tv.getlayout().getlinestart(3)),0,48+24, paint);     canvas.save();

whats problem.

i tried too

bitmap = bitmap.createbitmap(tv.getwidth(),tv.getheight(),config.rgb_565);         canvas=new canvas(bitmap);         canvas.drawargb(255,0,255,0);         final textpaint paint = new textpaint(color.blue);         paint.setstyle(style.fill);         paint.setantialias(true);         paint.settypeface(typeface.serif);         paint.settextsize((int) 24);         canvas.save();         staticlayout sl= new staticlayout(tv.gettext().tostring(), paint, bitmap.getwidth(), android.text.layout.alignment.align_normal, 1.0f, 0.0f, false);         sl.draw(canvas);

but in result getting line cutting text , underline too. please advice

textviews word wrap. drawtext not, design. if need that, need use staticlayout wrapping.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
