供参考：http: //developer.android.com/reference/android/util/DisplayMetrics.html

你可以像这样得到 dpi 值；

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

并将density属性与常数进行比较；

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
