android获取屏幕信息

通过WindowManager获取

  DisplayMetrics dm = new DisplayMetrics();        getWindowManager().getDefaultDisplay().getMetrics(dm);        Log.i("--","width-display :" + dm.widthPixels);        Log.i("--","heigth-display :" + dm.heightPixels);

通过Resources获取

DisplayMetrics dm2 = getResources().getDisplayMetrics();        Log.i("--","width-display :" + dm.widthPixels);        Log.i("--","heigth-display :" + dm.heightPixels);
