ANDROID : split the screen in 2 equals parts with 2 listviews

Question

I\'m trying to put 2 listviews into my layout. The problem is that I don\'t know the size of each listview in advance. The first listview could have a few items (0, 1, 2 up

Answer 1

Try to set sizes in soft pixels (device independent ones) - like "50sp" or "100sp" - I'm sure you'll find appropriate one

Answer 2

I simply had to "encapsulate" my 2 listviews into 2 separate linearlayouts => these 2 linearlayout have a weight of 1 :

    <LinearLayout android:layout_weight="1" 
                    android:layout_height="fill_parent" 
                    android:layout_width="fill_parent">

                <ListView   android:id="@+id/ListView_NASDAQ100" 
                            android:layout_height="fill_parent" 
                            android:layout_width="fill_parent">

                </ListView>
    </LinearLayout>

<LinearLayout android:layout_weight="1" 
                android:layout_height="fill_parent" 
                android:layout_width="fill_parent">

            <ListView   android:id="@+id/ListView_from_52w_HIGHLOW" 
                        android:layout_height="fill_parent" 
                        android:layout_width="fill_parent">

            </ListView>
</LinearLayout>

<LinearLayout
        android:id="@+id/ListView_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:weightSum="1" >

        <RelativeLayout
            android:id="@+id/rl_ListView1"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="0.5" >

            <ListView
                android:id="@+id/lv1"
                android:layout_width="match_parent"
                android:layout_height="wrap_content" >
                </ListView>
        </RelativeLayout>

        <RelativeLayout
            android:id="@+id/rl_ListView2"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="0.5" >

            <ListView
                android:id="@+id/lv2"
                android:layout_width="match_parent"
                android:layout_height="wrap_content" >
            </ListView>

        </RelativeLayout>
    </LinearLayout>

Create a parent Linear Layout, define a weightsum and split that into two different relative layouts each of weight equals half of total weightsum because in relative layout things are managed easily and properly .I hope this works for you
