How To Get current layout object on Android

In android using getLayoutInflater method in LayoutInflater class we can get current layout object.

Example Code:

 UI Layout (mainlayout.xml)

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@android:color/darker_gray"
    tools:context=".MainActivity" >
  <Button
                android:id="@+id/button"
                style="?android:attr/buttonStyleSmall"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                  />
  </RelativeLayout>

Here if we want to get current layout object use below code.
LayoutInflater inflater = getLayoutInflater();
RelativeLayout root= (RelativeLayout) inflater.inflate(R.layout.mainlayout,null);

And we can access Button  using root object
Button button= (Button) root.findViewById(R.id.record);
