问题
I Have listview in my xml file. Below listview I have other layouts. If I set android:layout_weight="1" in listview then after changing orientation it does not scroll and only layout below listview is visible . If I remove layout_weight="1" from listview then without changing orientation also listview is not visible. Here is my xml:

What should I do so listview is visible and after changing orientation scroll is also available. Thanks in advance

So here is my result. I think you should let the list view be 1/2 of the screen and with the rest of the elements add them a ScrollView

回答2:
You are missing a </LinearLayout>. I do not know if this will solve the problem. Also usually if you add the weight attribute you would add it to the other elements in that LinearLayout so that the layout can weight all the elements properly. By adding just the weight attribute, the other elements may by getting a 0 weight by default and hence would not be shown.
