获取屏幕分辨率的方式如下：
一、在activity中 
1、DisplayMetrics dm = getResources().getDisplayMetrics();
     int screenWidth = dm.widthPixels;
     int screenHeight = dm.heightPixels;

2、DisplayMetrics dm = new DisplayMetrics();
     this.getWindowManager().getDefaultDisplay().getMetrics(dm);
     int screenWidth = dm.widthPixels;
     int screenHeight = dm.heightPixels;
二、在service中
    DisplayMetrics dm = new DisplayMetrics();
    dm = getResources().getDisplayMetrics();
    int screenWidth = dm.widthPixels;
    int screenHeight = dm.heightPixels;
三、在非activity中，传一个Context进来调用
1、public ImageGalleryAdapter(Context c) { 
         myContext = c;
         DisplayMetrics dm = c.getResources().getDisplayMetrics();
         int screenWidth = dm.widthPixels;
         int screenHeight = dm.heightPixels;
    }
2、public class BaseTools {
          public static int getWindowWidth(Context context){
                // 获取屏幕分辨率
                WindowManager wm = (WindowManager) (context.getSystemService(Context.WINDOW_SERVICE));
                DisplayMetrics dm = new DisplayMetrics();
                wm.getDefaultDisplay().getMetrics(dm);
                int mScreenWidth = dm.widthPixels;
                return mScreenWidth;
         }
         public static int getWindowHeigh(Context context){
                // 获取屏幕分辨率
                WindowManager wm = (WindowManager) (context.getSystemService(Context.WINDOW_SERVICE));
                DisplayMetrics dm = new DisplayMetrics();
                wm.getDefaultDisplay().getMetrics(dm);
                int mScreenHeigh = dm.heightPixels;
                return mScreenHeigh;
         }
}
