    <p>I've been struggling to lay out two ListViews in a vertical LinearLayout. I finally saw the answer on here about wrapping each in their own LinearLayout, and adding each one of these LinearLayouts to the original LinearLayout with weights of 1. So that's what I tried... but I just cannot seem to get this to work.</p> <p>I'm doing this all in code:</p> <pre><code>public class MyDualList extends LinearLayout { private LinearLayout _layout1; private LinearLayout _layout2; private ListView _list1; private ListView _list2; public MyDualList(Context context, ListView list1, ListView list2) { super(context); _list1 = list1; _list2 = list2; _layout1 = new LinearLayout(context); _layout1.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, 0, 1)); _layout1.addView(_list1, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); _layout2 = new LinearLayout(context); _layout2.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, 0, 1)); _layout2.addView(_list2, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); addView(_layout1); addView(_layout2); } } </code></pre> <p>This is my latest attempt, but I swear I've tried every combination/setting for the LayoutParams' height (FILL_PARENT, WRAP_CONTENT, 0) as well as various weights.</p> <p>The result is never very good; if my second list is very long, it inevitably takes up the vast majority of the original vertical layout (certainly much more than 50%).</p> <p>I'm not going to give up! Maybe someone can help me out a bit.</p> <p>Thanks, Ken</p>

    1. CONot sure if this relates, but I think there was a difference with the addView methods. Can you try to call: `addView(_layout1, new LayoutParams(LayoutParams.FILL_PARENT, 0, 1));` instead of setting the LayoutParams beforehand. Same for `_layout2`.

    2. CO@Sebastian - that won't make any difference. `addView(aView)` is exactly the same as `addView(aView, aView.getLayoutParams())`.

    3. COI'm not quite sure why you need _layout1 and _layout2. Why not just set the heights of _list1 and _list2 to 0, their weights to 1, and add them directly to the dual list?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
