Android button font size
You define these attributes in xml as you would anything else, for example:
<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" /> <!-- Use SP(Scale Independent Pixel) -->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.
Button butt= new Button(_context);butt.setTextAppearance(_context, R.style.ButtonFontStyle);and in res/values/style.xml
<resources> <style name="ButtonFontStyle"> <item name="android:textSize">12sp</item> </style></resources>
Programmatically:
Button bt = new Button(this);bt.setTextSize(12);In xml:
<Button android:textSize="10sp"/>
