java - What is wrong with these static getter & setter methods - Android? -


i'm befuddled tiny problem in android code. getters , setters created in custom class (i.e. 'resultsroominfocustrlyt') give me following 'java nullpointerexception':

05-31 13:37:13.222  29262-29262/com.whitsoft.stan e/androidruntime﹕ fatal exception: main java.lang.nullpointerexception         @ com.whitsoft.stan.mods.resultsroominfocustrlyt.setsingleroomsnumbertextvalue(resultsroominfocustrlyt.java:61)         @ com.whitsoft.stan.utils.datafixer.updaterelevantviewswithselecteddata(datafixer.java:48)         @ com.whitsoft.stan.mods.stanlistfragment.checkifthelistadapterdatahaschanged(stanlistfragment.java:98)         @ com.whitsoft.stan.mods.stanlistfragment.onactivitycreated(stanlistfragment.java:49)         @ android.app.fragment.performactivitycreated(fragment.java:1707)         @ android.app.fragmentmanagerimpl.movetostate(fragmentmanager.java:921)         @ android.app.fragmentmanagerimpl.movetostate(fragmentmanager.java:1075)         @ android.app.backstackrecord.run(backstackrecord.java:682)         @ android.app.fragmentmanagerimpl.execpendingactions(fragmentmanager.java:1455)         @ android.app.fragmentmanagerimpl$1.run(fragmentmanager.java:441)         @ android.os.handler.handlecallback(handler.java:730)         @ android.os.handler.dispatchmessage(handler.java:92)         @ android.os.looper.loop(looper.java:137)         @ android.app.activitythread.main(activitythread.java:5493)         @ java.lang.reflect.method.invokenative(native method)         @ java.lang.reflect.method.invoke(method.java:525)         @ com.android.internal.os.zygoteinit$methodandargscaller.run(zygoteinit.java:1209)         @ com.android.internal.os.zygoteinit.main(zygoteinit.java:1025)         @ dalvik.system.nativestart.main(native method)

here custom class ('resultsroominfocustrlyt') getters & setters implemented:

public class resultsroominfocustrlyt extends relativelayout {  layoutinflater staninflater; private static textview singleroomsnumbertv, singleroomsdesctv, viproomsnumbertv, viproomsdesctv;  public resultsroominfocustrlyt(context context) {     super(context);      staninflater = layoutinflater.from(context);     initializeandlayoutchildren(); }  public resultsroominfocustrlyt(context context, attributeset attrs) {     super(context, attrs);      staninflater = layoutinflater.from(context);     initializeandlayoutchildren(); }  public resultsroominfocustrlyt(context context, attributeset attrs, int defstyleattr) {     super(context, attrs, defstyleattr);      staninflater = layoutinflater.from(context);     initializeandlayoutchildren(); }  private void initializeandlayoutchildren() {      staninflater.inflate(r.layout.cust_rlyt_results_room_info, this, true);      singleroomsnumbertv = (textview) findviewbyid(r.id.stan_single_rooms_number_tv);     singleroomsdesctv = (textview) findviewbyid(r.id.stan_single_rooms_description_tv);     viproomsnumbertv = (textview) findviewbyid(r.id.stan_vip_rooms_number_tv);     viproomsdesctv = (textview) findviewbyid(r.id.stan_vip_rooms_description_tv); }  public static string getsingleroomsnumbertextvalue() {     return singleroomsnumbertv.gettext().tostring(); }  public static void setsingleroomsnumbertextvalue(string singleroomsnumbertext) {     singleroomsnumbertv.settext(singleroomsnumbertext); }   public static void setviproomsnumbertextvalue (string viproomsnumbertext) {     viproomsnumbertv.settext(viproomsnumbertext); }  public static string getviproomsdesctextvalue () {     return viproomsdesctv.gettext().tostring(); }  public static void setviproomsdesctextvalue (string viproomsdesctext) {     viproomsdesctv.settext(viproomsdesctext); }  }

...as can see love using static getters , setters gives me easy access required views single line of code. odd thing error getting @ runtime have 2 other classes 1 use same setup - , classes work fine (update data required). however, when class's setters called following calls fail execute:

resultsroominfocustrlyt.setsingleroomsnumbertextvalue(singleroomsnumberinfo);     resultsroominfocustrlyt.setsingleroomsdesctextvalue(singleroomsdescinfo);     resultsroominfocustrlyt.setviproomsnumbertextvalue(viproomsnumberinfo);     resultsroominfocustrlyt.setviproomsdesctextvalue(viproomsdescinfo);

any appreciated. thanks. shore-t.

well problem trying set texts of null text views. example, following line:

resultsroominfocustrlyt.setsingleroomsnumbertextvalue(singleroomsnumberinfo);

tries following:

singleroomsnumbertv.settext(singleroomsnumbertext);

but singleroomsnumbertv? assigned? need call:

new resultsroominfocustrlyt(this);

from activity initialize static textviews.
