Android获取设备屏幕宽高像素值的两个方法

private void get1() {
    Resources resources = this.getResources();
    DisplayMetrics dm = resources.getDisplayMetrics();
    int width = dm.widthPixels;
    int height = dm.heightPixels;
    Log.d("方法1", width + " , " + height);
}  

private void get2() {
    WindowManager manager = this.getWindowManager();
    DisplayMetrics outMetrics = new DisplayMetrics();
    manager.getDefaultDisplay().getMetrics(outMetrics);
    int width = outMetrics.widthPixels;
    int height = outMetrics.heightPixels;
    Log.d("方法2", width + " , " + height);
