scrollview with tablelayout and linearlayouts

Question

I have a ScrollView layout with a TableLayout in which i have a TableRow which consists of three TextViews.

The problem arises when i try to align the TextViews with the screen. The TextViews don't take up the space of the screen and kind of cram up.

I have attached the code too if you guys need to review it ...

Answer 1

Set in LinearLayout android:layout_weight="2.5" which is sum of layout weight of LinearLayout children. After this Layout should be aligned to left and right.

<LinearLayout android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:layout_weight="2.5"
    android:id="@+id/linear_layout_two_table_layout">
