LinearLayout doesn't fill tablerow even width fill_parent is called

Question

I have a linearLayout inside a tableRow, this linearLayout contains a chart that i would like to display for my app. I read some thread saying that the child of the tableRow not need to specify its width and height, so I did it, but the chart is not displayed. If I specify the linearLayout to be width=fill_parent and height=200dp, then the linearlyLayout is only fill 1/3 of the tableRow.

Answer 1

I found out just set the weight = 1(or any number) for the linearLayout

<LinearLayout
                android:id="@+id/soundaomplitude_graphViewLinearLayout"
                android:layout_width="0dp"
                android:layout_height="200dp"
                android:layout_weight="1"
                android:paddingTop="4dip" />

Answer 2

It seems that a TableRow acts as a LinearLayout, hence nesting one right inside a TableRow seems redundant. In Eclipse also, it says, that it is "useless". Therefore, you can just include your view (any view) directly inside the TableRow, instead of the LinearLayout. If it is not showing, then, there is probably some other problems.
