You need both getText   - which returns an Editable and toString   - to convert that to a String for matching  So instead of  passw1 toString   equalsIgnoreCase  1234   you need passw1 getText   toString   equalsIgnoreCase  1234

You can compare the values using equals   of Java    public void onClick View v           TODO Auto-generated method stub      s1 text1 getText   toString        s2 text2 getText   toString         if s1 equals s2           Show setText  Are Equal        else         Show setText  Not Equal

Try to use  trim   first  before  equals    or create a new String var that has these things

Using the    operator will compare the references to the strings not the string themselves   Ok  you have to toString   the Editable  I loaded up some of the code I had before that dealt with this situation   String passwd1Text   passw1 getText   toString    String passwd2Text   passw2 getText   toString     if  passwd1Text equals passwd2Text

ou can use String compareTo String  that returns an integer that s negative   lt    zero    or positive      Use it so   You can use String compareTo String  that returns an integer that s negative   lt    zero    or positive      Use it so     String a  myWord     if a compareTo another string   lt 0         a is strictly  lt  to another string       else if  a compareTo another string     0         a equals to another string     else       a is strictly  gt  than another string

EDIT  I made a mistake earlier  because  to get the text  you need to use  getText   toString     Here is a full working example   package com psegina passwordTest01   import android app Activity  import android os Bundle  import android view View  import android view View OnClickListener  import android widget Button  import android widget EditText  import android widget LinearLayout  import android widget Toast   public class Main extends Activity implements OnClickListener       LinearLayout l      EditText user      EditText pwd      Button btn        Override     public void onCreate Bundle savedInstanceState            super onCreate savedInstanceState            l   new LinearLayout this           user   new EditText this           pwd   new EditText this           btn   new Button this            l addView user           l addView pwd           l addView btn           btn setOnClickListener this            setContentView l              public void onClick View v           String u   user getText   toString            String p   pwd getText   toString            if  u equals  p                 Toast makeText getApplicationContext     Matches   Toast LENGTH SHORT  show            else             Toast makeText getApplicationContext    user getText          pwd getText    Toast LENGTH SHORT  show              Original answer  Will not work because of the lack of toString     Try using  getText   instead of  toString     if  passw1 getText      passw2 getText      do something    toString   returns a String representation of the whole object  meaning it won t return the text you entered in the field  see for yourself by adding a Toast which will show the output of  toString
