Resolution processing for Android programming related code segment collections

An example of RESOLUTION processing for Android programming is presented in this paper. To share for your reference, the details are as follows:

1. Screen resolutions commonly referred to as 800x480, 960x540, etc. These resolutions are available in code. Mobile phone screen resolution calculation:

//  Calculate your phone's screen resolution 
private void computeDisplayMetrics() {
  //  The resolution of the mobile phone screen is heightxwidth
  DisplayMetrics dm = new DisplayMetrics();
  this.getWindowManager().getDefaultDisplay().getMetrics(dm);
  int width = dm.widthPixels;
  int height = dm.heightPixels;
  //  The current resolution of the mobile phone screen is width x height
}

2. Switch from dp to px according to the resolution of the phone:

public static int dip2px(Context context,float dpValue) {
  final float scale = context.getResources().getDisplayMetrics().density;
  return (int) (dpValue * scale + 0.5f);
}

3. Switch from px(pixels) to dp according to the resolution of the phone:

public static int px2dip(Context context,float pxValue) {
  final float scale = context.getResources().getDisplayMetrics().density;
  return (int) (pxValue / scale + 0.5f) - 15;
}

I hope this article has been helpful for Android programming.
