could tell me how solve problem?

your textviews have no width. required attribute.

<textview android:id="@+id/articletitle" android:choicemode="singlechoice" android:layout_height="20dp" android:layout_width="match_parent" android:minheight="20dp" /> <textview android:id="@+id/articleabstract" android:choicemode="singlechoice" android:layout_height="80dp" android:layout_width="match_parent" android:minheight="80dp" />

android xml android-layout-weight
