Edit: as misunderstood original question:

int mPosition = -1;   

lv.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {

    public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
                int pos, long id) {

        if(mPosition!=-1) {
            //reset color of previously pressed item to white
            lv.getChildAt(mPosition).setBackgroundColor(Color.WHITE);
        }
        //set current item to fray.
        lv.getChildAt(pos).setBackgroundColor(Color.GRAY);
        //put value of currently selected item to mPosition.
        mPosition = pos;

        return true;
    }
});

Old answer below:

Add this into your method.

Button button1 = (Button)findViewById(R.id.button1);
if(this condition){
    button1.setBackgroundColor(Color.GRAY);
}else{
    //whatever.. 
}

This answer covers the same principle, but in more detail using the resources.

you can give color to list item when selected with

android:listSelector="@color/AnyColor" in .xml file .. see coding

<ListView
    android:id="@+id/nameOfYourListview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_margin="10dp"
    android:background="AnyYouWant"
   <!--code for color the selected item --> android:listSelector="ColorHereWhichYouWant" >
</ListView>
