Android - How to programmatically set the button style in a Linearlayout?

I am programmatically creating a LinearLayout for an AlertDialog with some buttons.

I WANT to do this:

<LinearLayout android:id="@+id/footer" android:layout_width="fill_parent"
style="@android:style/ButtonBar">

But with code like this:

LinearLayout buttons = new LinearLayout(parentContext);
buttons.setOrientation(LinearLayout.HORIZONTAL);
LinearLayout.LayoutParams buttonsParams =
    new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,
    LayoutParams.WRAP_CONTENT);
topLayout.addView(buttons, buttonsParams);
buttons.setLayoutParams(buttonsParams);
Button btnAdd = new Button(context);
btnAdd.setText("Add");

How can I set the style of the buttons (use a button bar) programmitically?

Hope I'm not too late to join the party :)

Well, Styles can be applied to a View at initialization phase. For example:

LinearLayout button = new LinearLayout(context, null, android.R.style.ButtonBar);

This worked for me:

int buttonStyle = R.style.your_button_style;
Button button = new Button(new ContextThemeWrapper(context, buttonStyle), null, buttonStyle)

This is the only answer that actually delivered what I was looking for: http://belencruz.com/2013/04/set-styles-programmatically-in-android/

Essentially, create a layout XML file that simply has a <Button/> element with the style you want. Then, inflate it programmatically and just customize the button text.

Something along the lines of:

<?xml version="1.0" encoding="utf-8"?>
<Button style="@style/your_custom_style_here"/>

In code:

Button button = (Button)getLayoutInflater().inflate(R.layout.your_custom_button_layout_file, null);
button.setText("Your Text");
