java - EditText and Reflection -

my problem little particular.

i show forth in code:

    import android.app.activity; import android.content.context; import android.widget.edittext;  import java.lang.reflect.field; import java.util.hashmap;   public class myactivity extends activity {       public hashmap initedittext(context context){         hashmap list = new hashmap();         field[] fields = context.getclass().getdeclaredfields();          (field field : fields){             if(field.getname().startswith("e_")){                 string word = field.getname().substring(2);                 string firscaract = word.substring(0, 1).touppercase();                 string key = field.getname().substring(3);                 try{                     class<?> cl = field.gettype();                     // value of member in object: (object instance of myclass)                     //object o = field.get(c);                      if (edittext.class.isassignablefrom(cl)) {                         edittext value = (edittext) field.get(context);                         list.put(firscaract + key, value.gettext().tostring());                     }                  }                 catch (illegalaccessexception e){                     e.printstacktrace();                 }              }         }          return list;     } }` 

this class, myactivity, serve me mother class

    import android.os.bundle; import android.view.view; import android.widget.button; import android.widget.edittext; import android.widget.textview;  import java.lang.reflect.field; import java.util.hashmap; import java.util.iterator;   public class testactivity extends myactivity {     public edittext e_prenom = null;     private edittext e_nom = null;      private textview t_prenom = null;     private textview t_nom = null;      private button validate = null;      private textview display = null;      private hashmap list;      string text2 = "";      @override     public void oncreate(bundle savedinstancestate){         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_testt);          e_prenom = (edittext) findviewbyid(r.id.edit_register_prenom);         e_nom = (edittext) findviewbyid(r.id.edit_register_nom);          t_prenom = (textview) findviewbyid(r.id.text_register_prenom);         t_nom = (textview) findviewbyid(r.id.text_register_nom);          validate = (button) findviewbyid(r.id.valider_register);          display = (textview) findviewbyid(r.id.affiche);          list = new hashmap();          e_prenom.settext("du con");         e_nom.settext("du puis");           list = initedittext(this);         iterator = liste.keyset().iterator();         stringbuilder builder = new stringbuilder();          while(it.hasnext()){             object key = it.next();             object value = liste.get(key);             builder.append(string.valueof(key) + "_" + string.valueof(value) + "\n");         }          text2 = builder.tostring();          validate.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view v) {                   display.settext(text2);             }         });     } } 

testactivity, child class inherits myactivity.

in myactivity initedittext method allows recover fields starting "e_" (those more precisely edittext) , storing names , values in hashmap.

in testactvity, have 2 edittext "e_prenom" , "e_nom". calling initedittext stock value in hashmap traveled , clicking on "validate" content of hahmap ("list") displayed in textview ("display").

so expect have result textview "prenom_du con" "nom_du puis".

but "prenom_du con" displayed.

anybody know why ?

after several investigations , tests noticed line

field[] fields = context.getclass().getdeclaredfields(); 

all fields recovered

but here

if (edittext.class.isassignablefrom(cl)) {                     edittext value = (edittext) field.get(context);                     list.put(firscaract + key, value.gettext().tostring());                 } 

only 1 of fields (edittext) has value retrieved.

is there property of view (edittext accurate in case) not know , cause ? comes property of field.get (object object)?

looks problem modifiers (public,private...):

public edittext e_prenom = null; private edittext e_nom = null; 

as can see 1 public, , other private.

to access private field, make accessible:

field.setaccessible(true); 

so overall, it'll like:

public hashmap initedittext(context context){     hashmap list = new hashmap();     field[] fields = context.getclass().getdeclaredfields();      (field field : fields){         field.setaccessible(true); //add line here         if(field.getname().startswith("e_")){             string word = field.getname().substring(2);             string firscaract = word.substring(0, 1).touppercase();
