Remove button shadow in java (Android)

Question

I need to remove shadow from a button. Since it is created in java (not in xml) I can't see the option to do so. I know the following line can be used in xml.

android:stateListAnimator="@null"

Tried the same in java as follows.

myButton.setStateListAnimator(null);

But the problem is, it will work only on devices with 21 API or above. Is there any alternative way?

By shadow do you mean elevation? and if so elevation is not present in devices below 21. And so, there will be no elevation on button for devices running <21. Did you run your code on <21 devices? — capt.swag, Dec 26 '15 at 11:51

put

android:background="@null"

I mean

myButton.setBackground(null);

EDIT: Other possibilities (sorry for xml):

Set elevation as 0:

mybutton.setElevation(0);
Set background as transparent:

android:background="@android:color/transparent"

Check: How to set transparent background for Image Button in code?

Set style to button:

    <Button
     ...
     style="?android:attr/borderlessButtonStyle"
      ....
     />

In Java code:

Button button = new Button(getApplicationContext(), null, android.R.attr
        .borderlessButtonStyle);
button = (Button) findViewById(R.id.buttonEndTime);

Use Button.setShadowLayer(float radius, float dx, float dy, int Color) and set radius to 0.
