根據屏幕密度的Android的HTML字體大小

Question

我需要一種方式來說，如果設備是LDPI或MDPI或HDPI設置HTML字體大小爲x。 e.g

if (ldpi){ 
htmlString.append("<br><p align='center'><font color='Yellow' size='5'>"); 
} 
else if (mdpi){ 
htmlString.append("<br><p align='center'><font color='Yellow' size='6'>"); 
} 
else if (hdpi){ 
htmlString.append("<br><p align='center'><font color='Yellow' size='7'>"); 
} 

任何幫助，將不勝感激

參考：http://developer.android.com/reference/android/util/DisplayMetrics.html

，你可以得到這樣的dpi值;

DisplayMetrics metrics = new DisplayMetrics(); 
getWindowManager().getDefaultDisplay().getMetrics(metrics); 

並比較density屬性與常量;

int DENSITY_DEFAULT The reference density used throughout the system. 
int DENSITY_HIGH Standard quantized DPI for high-density screens. 
int DENSITY_LOW Standard quantized DPI for low-density screens. 
int DENSITY_MEDIUM Standard quantized DPI for medium-density screens. 
int DENSITY_TV Standard quantized DPI for 720p TV screens. 
int DENSITY_XHIGH
