I executed the above url, but there is no change.

styles.xml

Create a shape named button_pressed.xml as follows....

<shape xmlns:android="http://schemas.android.com/apk/res/android">

    <solid android:color="@color/blue" />

    <stroke
        android:width="4dp"
        android:color="@color/blue" />

    <padding
        android:bottom="1dp"
        android:left="1dp"
        android:right="1dp"
        android:top="1dp" />

</shape>

Suppose, you have tow button whose id s are R.id.btn and R.id.btn1 as follows...

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <Button
        android:id="@+id/btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="12dp"
        android:background="@drawable/button_pressed"
        android:onClick="onClick"
        android:text="Press Me 1" />

    <Button
        android:id="@+id/btn2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="12dp"
        android:background="@drawable/button_pressed"
        android:onClick="onClick"
        android:text="Press Me 2" />

</LinearLayout>

Write onClick() method as follows...which will allow you to retain the changed color until another button pressed.

Button button;

public void onClick(View v) {

    Drawable dr = getResources().getDrawable(R.drawable.button_pressed);
    dr.setColorFilter(Color.parseColor("#FF0000"), PorterDuff.Mode.SRC_ATOP);

    switch (v.getId()) {
    case R.id.btn:

        if (button == null) {
            button = (Button) findViewById(v.getId());
        } else {
            button.setBackgroundResource(R.drawable.button_pressed);
            button = (Button) findViewById(v.getId());
        }
        button.setBackgroundDrawable(dr);

        break;

    case R.id.btn2:
        if (button == null) {
            button = (Button) findViewById(v.getId());
        } else {
            button.setBackgroundResource(R.drawable.button_pressed);
            button = (Button) findViewById(v.getId());
        }
        button.setBackgroundDrawable(dr);

        break;

    default:
        break;
    }
}

Hope this work for you.Just let me know if it work.

Realized in the following.

styles.xml
    <style name="PopupMenu" parent="@android:style/Widget.PopupMenu">
