Android 根据屏幕大小设置字体

public static int adjustFontSize(int screenWidth, int screenHeight){
        if (screenWidth <= 240) {       // 240X320 屏幕           
            return 10;
        }else if (screenWidth <= 320){  // 320X480 屏幕
            return 14;
        }else if (screenWidth <= 480){  // 480X800 或 480X854 屏幕
            return 24;
        }else if (screenWidth <= 540){  // 540X960 屏幕 

            return 26;          
        }else if(screenWidth <= 800){   // 800X1280 屏幕 

            return 30;          
        }else{                          // 大于 800X1280

            return 30;          
        }
}
