you have mistake in article layout. article layout has horizontal orientation, , it's child textview has match_parent width, when add new child, it'll outside screen. change orientation vertical:
<linearlayout android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/articlelayout" android:orientation="vertical"> <---- change line <textview android:layout_width="match_parent" android:layout_height="wrap_content" android:text="read more" android:textsize="15dp" android:textstyle="bold" android:layout_gravity="center" android:clickable="true" android:focusable="false" android:gravity="center" android:onclick="readmore" android:padding="1dp" android:textcolor="@android:color/holo_green_light" /> </linearlayout>
