                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:layout_marginLeft="@dimen/spacing_large"
                        android:layout_marginRight="@dimen/spacing_large"

use SharedPreferences to save Your Own TextSize

code to save textsize in SharedPreferences: 

  SharedPreferences  pref=getSharedPreferences("MyPref",MODE_PRIVATE);              
   SharedPreferences.Editor editor=pref.edit();            
   editor.putFloat(FONT_SIZE_KEY,textSize);    // your textsize       
   editor.commit();

to retreive textsize Value from SharedPreferences

       SharedPreferences prefs=getSharedPreferences("MyPref", MODE_PRIVATE);
       float fontsize=prefs.getFloat(FONT_SIZE_KEY, 12);
