android - Returning strings to a previous activity usint intents -

i have 2 activities has second activity return text inputs user , respectively change textviews. however, when passing text inputs second activity returning empty.

the second activity's onclick method goes main activity:

public void onclick(view v)         {             intent = new intent();             edittext txt1 = (edittext)findviewbyid(r.id.txt_name);             i.putextra("str3", txt1.gettext());              edittext txt2 = (edittext)findviewbyid(r.id.txt_address);             i.putextra("str4", txt2.gettext());              setresult(result_ok, i);             finish();         }     }); } 

the method called after second activity finishes

public void onactivityresult(int requestcode,int resultcode, intent data) {     textview txt = (textview)findviewbyid(r.id.txt_one);     txt.settext(getintent().getstringextra("str3")); } 

try below

 public void onactivityresult(int requestcode,int resultcode, intent data)  {  txt.settext(getintent().getstringextra("str3"));  } 

also move initialization oncreate.

textview txt ; @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     txt = (textview)findviewbyid(r.id.txt_one);     ... // rest of code  } 

the same edittext's also. declare class members , initialize in oncreate no need intialize everytime on button click

edit:

also use below

public editable gettext ()

added in api level 1

return text textview displaying. if settext() called argument of buffertype.spannable or buffertype.editable, can cast return value method spannable or editable, respectively. note: content of return value should not modified. if want modifiable one, should make own copy first.

  string value1 = txt1.gettext().tostring();   i.putextra("str3", value1);
