How to change Style in Android

Question

Im using the following Styles, ButtonBlue is used normally. Over the Menu the Style should be changed to ButtonBlue.Big the Styles look like this:

  <style name="ButtonBlue" parent="android:Widget.Button">
        <item name="android:layout_weight">1</item>
        <item name="android:backgroundTint">@android:color/holo_blue_bright</item>
    </style>
    <style name="ButtonBlue.Big" parent="ButtonBlue">
        <item name="android:textSize">20sp</item>
    </style>

is there a way to change the Style to more than one Button? Because i have 31 Buttons and it would be really a lot of LoC if have to change it manually for every Button with

bt.setTextAppearance(this,R.style.ButtonBlue_Big);

Thanks in advance

Edit: I applied the ButtonBlue Style in the activity.xml

       <Button
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="@string/buttonInvert"
        style="@style/ButtonBlue"
        android:id="@+id/buttonInvert"
       android:onClick="buttonOnClick"/>

But my problem is, that i don't know how i can apply the new Style via Button in the Java-Code

    public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();
    if (id == R.id.number_small) {
        //apply the Style here
        return true;
    }

    return super.onOptionsItemSelected(item);
}

Set your style to every Button in your XML layout file. For example:

<Button
    style="@style/ButtonBlue.Big"
    android:text="@string/myButtonText" />

Etc.

You can do like this in your layout for all buttons,

<Button
 .....
 ..... 
  style="@style/ButtonBlue_Big"
/>

okay, then you need to do it for all button in the activity code. – Narendra Singh May 17 '15 at 19:50

Create .xml in the res/styles folder and use that file as android style attribute in the main.xml

Search on google lots of tutorials available.
