Why my Android Listview is not scrolling?

Question

I have made a xml display with some items . But my listView of that xml is not scrolling. I have made a scrollView and the listView is inside the scrollView , is it a problem ? If I design display with keeping the listView out side the scrollView, then the lisViw is not showing on my android device display. I need such a display where need a scrollView and scrolling listview. My code is given below.

Answer 1

As samir and coader said, never use them in scrollview; but let this time be an exception, first check whether you've entered enough no. of items inside the list such tat there is enough no. of objects to scroll

Answer 2

Do not put a ListView inside a ScrollView.

ListView already handles scrolling, you're only going to run into trouble.

Using a ListView to make it not scroll is extremely expensive and goes against the whole purpose of ListView. You should NOT do this. Just use a LinearLayout instead.

Answer 3

Never add ListView,MapView,WebView(its already scrollable) in ScrollView

Remove from ScrollView.
