android - LazyList set item height -
i using listview lazyadapter , need change item row height, seems little more tricky. here adapter:
public class albumdetailsadapter extends baseadapter { private activity activity; private arraylist<songs> data; private static layoutinflater inflater = null; private mediaplayer mediaplayer; public albumdetailsadapter(activity a, arraylist<songs> products) { activity = a; mediaplayer = new mediaplayer(); data = products; inflater = (layoutinflater) activity .getsystemservice(context.layout_inflater_service); } public int getcount() { return data.size(); } public object getitem(int position) { return position; } public long getitemid(int position) { return position; } public view getview(final int position, view convertview, viewgroup parent) { view vi = convertview; if (convertview == null) vi = inflater.inflate(r.layout.songs_items, parent); textview songnumber = (textview) vi .findviewbyid(r.id.songs_item_number); textview albumtitle = (textview) vi .findviewbyid(r.id.songs_item_album_title); textview singer = (textview) vi .findviewbyid(r.id.songs_item_album_singer); final imageview playsong = (imageview) vi.findviewbyid(r.id.songs_item_play); imageview downloadsong = (imageview) vi .findviewbyid(r.id.songs_item_download); if (!data.get(position).getsong_mp3() .equals("http://nelu.burduja.com/musica/songs_with/")) { downloadsong.setbackgroundresource(r.drawable.down_yes); if (!mediaplayer.isplaying()) { playsong.setbackgroundresource(r.drawable.play_nr); } playsong.setonclicklistener(new onclicklistener() { @override public void onclick(view v) { if (mediaplayer.isplaying()) { mediaplayer.release(); playsong.setbackgroundresource(r.drawable.play_nr); mediaplayer=new mediaplayer(); } else { playsong.setbackgroundresource(android.r.drawable.ic_media_pause); try { mediaplayer.setdatasource(data.get(position) .getsong_mp3()); final progressdialog bufferingdialog=new progressdialog(activity); bufferingdialog.setmessage("buffering ..."); bufferingdialog.show(); mediaplayer.prepareasync(); mediaplayer.setonpreparedlistener(new onpreparedlistener() { @override public void onprepared(mediaplayer arg0) { bufferingdialog.dismiss(); mediaplayer.start(); } }); mediaplayer.setoncompletionlistener(new oncompletionlistener() { @override public void oncompletion(mediaplayer arg0) { playsong.setbackgroundresource(r.drawable.play_nr); mediaplayer.release(); } }); } catch (illegalargumentexception e) { // todo auto-generated catch block e.printstacktrace(); } catch (securityexception e) { // todo auto-generated catch block e.printstacktrace(); } catch (illegalstateexception e) { // todo auto-generated catch block e.printstacktrace(); } catch (ioexception e) { // todo auto-generated catch block e.printstacktrace(); } } } }); } imageview youtube = (imageview) vi.findviewbyid(r.id.songs_item_video); if (data.get(position).getsong_mp4().length() > 0) { youtube.setbackgroundresource(r.drawable.video_nr); youtube.setonclicklistener(new onclicklistener() { @override public void onclick(view v) { intent intent = new intent(intent.action_view, uri .parse(data.get(position).getsong_mp4())); v.getcontext().startactivity(intent); } }); } albumtitle.settext(data.get(position).getsong_title()); singer.settext(data.get(position).getsong_artist()); songnumber.settext((position + 1) + ""); return vi; } } and songs_item xml file:
