How to dynamically add a drawable (.xml) to buttons (generated dynamically)

I have a method that creates dynamically an array of Button

 for(int i = 0; i < 10; i++){
     Button button = new Button(activity);
     LinearLayout.LayoutParams lparams = new LinearLayout.LayoutParams(200, 100);
     button.setLayoutParams(lparams);
     button.setTag(0);
     buttonArray[i] = button;
     layout.addView(button);
 }

I created a drawable (d.xml) that I have to apply to the buttons

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <stroke
        android:width="1dp"
        android:color="#FFFFFF"/>
</shape>

What I'm not able to do is to apply d.xml to the buttons that I create dynamically.

Can somebody help me? Thank you in advance.

Once you have created your background drawable, you can apply this to the dynamically generated Button in your code.

If your minimum build is API 21 (Lollipop), then use

button.setBackground(activity.getDrawable(R.drawable.d)

You can also use setBackgroundDrawable for lower APIs.

A more suitable solution can be to use 

button.setBackgroundResouce(R.drawable.d)

Give those a go!

in your for loop, after button.setTag(0); do this button.setBackground(ContextCompat.getDrawable(this, R.drawable.d));

Use

 button.setBackgroundResource(R.drawable.your_resource);

Use set background resource of Button :

 for(int i = 0; i < 10; i++){
     Button button = new Button(activity);
     LinearLayout.LayoutParams lparams = new LinearLayout.LayoutParams(200, 100);
     button.setLayoutParams(lparams);
     button.setTag(0);
     button.setBackgroundResource(R.drawable.d);
     buttonArray[i] = button;
     layout.addView(button);
 }
