Android NumberPicker: Set min, max, default from XML

Is there a way to set the minimum, maximum and default values of a NumberPicker from the XML Layout?

I'm doing it from within the Activity code:

np = (NumberPicker) findViewById(R.id.np);
np.setMaxValue(120);
np.setMinValue(0);
np.setValue(30);

XML is obviously more appropriate , because it defines property, not behaviour.

Is there a way to set these using the XML layout?

I had the same problem, this is how I solved it (according to the comment of MKJParekh):

1. I created my own NumberPicker-Class

   package com.exaple.project;
   
   import android.annotation.TargetApi;
   import android.content.Context;
   import android.os.Build;
   import android.util.AttributeSet;
   import android.widget.NumberPicker;
   
   @TargetApi(Build.VERSION_CODES.HONEYCOMB)//For backward-compability
   public class MyNumberPicker extends NumberPicker {
   
       public MyNumberPicker(Context context) {
           super(context);
       }
   
       public MyNumberPicker(Context context, AttributeSet attrs) {
           super(context, attrs);
           processAttributeSet(attrs);
       }
   
       public MyNumberPicker(Context context, AttributeSet attrs, int defStyle) {
           super(context, attrs, defStyle);
           processAttributeSet(attrs);
       }
       private void processAttributeSet(AttributeSet attrs) {
           //This method reads the parameters given in the xml file and sets the properties according to it
           this.setMinValue(attrs.getAttributeIntValue(null, "min", 0));
           this.setMaxValue(attrs.getAttributeIntValue(null, "max", 0));
       }
   }
   

2. Now you can use this NumberPicker in your xml layout file

   <com.exaple.project.myNumberPicker
       android:id="@+id/numberPicker1"
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       android:layout_gravity="center"
       android:orientation="vertical"
       max="100"
       min="1" />
