Android ListView and ScrollView conflict issues

A recent app, which has a microblogging-like Comment feature interface, first lists the text content and pictures of the microblog. Then there is the comment below.

Start with a scrollview to wrap up the main content and the ListView in the comment area. Then add the contents of the individual controls (yes, it feels a bit like the CSDN blog's editing interface), but after writing it, I find that the ListView only shows the height of an entry. And can not slide, search the Internet to find the reason is that ScrollView and the ListView are sliding, put them in a piece will conflict. Finally, ScrollView got the focus. The ListView cannot be slid. The most common solution on the web is to use getmeasure to calculate the height of each entry and cut line when loading a ListView, then add the result to the height of the ListView control, just as if it were only applicable to the same height of each item in the ListView (not tried. Very strange why this is so). Either you define a control that inherits from the ListView, and it is the height of the ListView set beforehand. But it's always more troublesome. And the accuracy is not as good as the system itself.

Lazy cancer attack really do not want to do these things, so I would like to try a more speculative method, that is, in the adapter of the ListView GetView method based on position constructs a different interface, that is, assuming that position is 0, then use the original main information (micro-bo text, image) of the XML file take inflate Convertview, or use the comment entry XML to inflate, after testing is feasible. Then do not forget to see if there is a better way to achieve. Went to overflow to find a bit, found that someone recommended the method is almost the same as mine. So I think that this method is better, do not need to do extra work, just need to put inflate's work by the main activity in the adapter can be.

GetView method

@Overridepublic view GetView (int position, view Convertview, ViewGroup parent) {/* Main information interface */if (0 = = position) {Mainholder Holder = Null;convertview = Inflater.inflate (R.layout.info, parent, false); holder = new Mainholder (); Convertview.settag (holder);               ······} /* Comment interface */else{itemholder holder = Null;convertview = Inflater.inflate (R.layout.item, parent, false); holder = new Itemholder (); Convertview.settag (holder); return Convertview;}}
