edit:do not put listview in expandableview. first problem.second 1 graph's height zero.(look in details http://developer.android.com/guide/topics/ui/how-android-draws.html ) these problems.for listview used textviews , put values in them loop. graph problem check device's pixel values , setlayoutparameters depending on whether portrait or landscape.here code used it.it gives values on devices use there may better solution.
int orientation = getresources().getconfiguration().orientation; displaymetrics metrics = new displaymetrics(); getactivity().getwindowmanager().getdefaultdisplay().getmetrics(metrics); int height=metrics.heightpixels; int width = metrics.widthpixels; if (orientation == 1) { sgv.setlayoutparams(new layoutparams(width, height/4)); } else { sgv.setlayoutparams(new layoutparams(width, height/2)); } i'm implementing expandablelistview has 2 different type of children view , listview.i use 2 different layout files both have 2 child layout child_list.xml , child_img.xml
the problem if don't set layout width , height gives normal width 0 height view , normal width , not enough height listview can see 1 element of listview.however if set layoutparameters (1200,400) show listview elements.
without setting height or width how can show list elements?
