question: private static void autofit ( TextView view , TextPaint paint , float minTextSize , float maxTextSize , int maxLines , float precision ) { if ( maxLines <= 0 || maxLines == Integer . MAX_VALUE ) { return ; } int targetWidth = view . getWidth ( ) - view . getPaddingLeft ( ) - view . getPaddingRight ( ) ; if ( targetWidth <= 0 ) { return ; } CharSequence text = view . getText ( ) ; TransformationMethod method = view . getTransformationMethod ( ) ; if ( method != null ) { text = method . getTransformation ( text , view ) ; } Context context = view . getContext ( ) ; Resources r = Resources . getSystem ( ) ; DisplayMetrics displayMetrics ; float size = maxTextSize ; float high = size ; float low = 0 ; if ( context != null ) { r = context . getResources ( ) ; } displayMetrics = r . getDisplayMetrics ( ) ; paint . set ( view . getPaint ( ) ) ; paint . setTextSize ( size ) ; if ( ( maxLines == 1 && paint . measureText ( text , 0 , text . length ( ) ) > targetWidth ) || getLineCount ( text , paint , size , targetWidth , displayMetrics ) > maxLines ) { size = getAutofitTextSize ( text , paint , targetWidth , maxLines , low , high , precision , displayMetrics ) ; } if ( size < minTextSize ) { size = minTextSize ; } view . setTextSize ( TypedValue . COMPLEX_UNIT_PX , size ) ; }
target:  Re-sizes the textSize of the TextView so that the text fits within the bounds of the View.
