Mahesh, Why dont you make a different class, say PlayBackView, extending LinearLayout and place the layout of the common component "Playback bar" in a different layout xml, say playback.xml.
Now inflate the playback.xml in the PlayBackView. Now you can add this your custom view in any of the layout xml (home, A, B, C) as: <?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/ android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <com.packagename.PlayBackView android:id="@+id/playbackview" android:layout_width="match_parent" android:layout_height="wrap_contentt" /> <ImageView ------- etc etc/> </FrameLayout> In the PlayBackView class, you can define the onClick handlers or any other event handler as you want. Hope this will help you.
