This may be off topic  but for those who are struggling on how to exactly change also the font of the button text  that was my case and Skatephone s answer helped me  here s how I did it  if you made buttons ind design mode    First we need to have the button s string name  converted   it s a foul way to explain  but straightforward  into java from the xml  and so we paste the aforementioned code into our MainActivity java      IMPORTANT  place the code under the OnCreate method    import android widget RemoteViews   RemoteViews remoteViews   new RemoteViews getPackageName    R layout my layout   remoteViews setTextViewText R id Counter   Set button text here         Keep in mind    my layout has to be substituted with the xml file where your buttons are  Counter has to be substituted with the id name of your button     id ButtonName    if you want to change the button text just insert the text in place of  Set button text here      here comes the part where you change the font    Now that you  converted  from xml to java  you can set a Typeface method for TextView  Paste the following code exactly under the previous one just described above  TextView txt    TextView  findViewById R id text your text view id           Typeface font   Typeface createFromAsset getAssets     fonts MyFontName ttf            txt setTypeface font     where in place of text your text view id you put your button s id name  like as previous code  and in place of MyFontName ttf you put your desired font     WARNING  This assumes you already put your desired font into the   assets font folder  e g  assets fonts MyFontName ttf

You can use the setText   method  Example   import android widget Button   Button p1 button    Button findViewById R id Player1   p1 button setText  Some text      Also  just as a point of reference  Button extends TextView  hence why you can use setText   just like with an ordinary TextView
