error:

08-03 16:12:00.992: e/androidruntime(28017): java.lang.nullpointerexception: attempt invoke virtual method 'android.content.res.resources android.content.context.getresources()' on null object reference 08-03 16:12:00.992: e/androidruntime(28017):    @ com.jkmt.ppbanjir.adapter.tabspageradapter.getitem(tabspageradapter.java:62) 

adapter's instantiation

madapter = new tabspageradapter(getsupportfragmentmanager(), null);  viewpager.setadapter(madapter);  

the issue line

madapter = new tabspageradapter(getsupportfragmentmanager(), null);  

you passing null context, , assigning null member in adapter. when getitem called, , member referenced, app crashes nullpointerexception. change with

madapter = new tabspageradapter(getsupportfragmentmanager(), this); 

if inside activity, or

madapter = new tabspageradapter(getsupportfragmentmanager(), getactivity());   

if inside fragment
