Two methods for Android to get the width and height pixel values of the device screen

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);  
}  

　　The output is the same:
