Android button font size

Question

I ve been trying to create a custom button in android using this tutorial - http   www gersic com blog php id 56  It works well but it doesn t say how to change the font size or weighting  Any ideas   There was another question on here and the only answer was to use html styling but you can t change a font size in html without using css  or the deprecated font tag   There must be a better way of setting the pixel size of the font used on buttons

Another approach   declaring an int first with the default fontsize  int txtSize   16                button setOnClickListener new View OnClickListener                      Override                 public void onClick View v                        mTextView setTextSize txtSize

You define these attributes in xml as you would anything else  for example    lt Button android id    id next button              android layout width  wrap content              android layout height  wrap content              android text   string next              android background   drawable mybutton background              android textSize  10sp    gt   lt  -- Use SP Scale Independent Pixel  -- gt    You can find the allowed attributes in the api   Or  if you want this to apply to all buttons in your application  create a style   See the Styles and Themes development documentation
