使用以下命令检查EditText值

Question

I am trying to do this, users are signing up, and for the password field I don't want to have two password fields (like traditionally password and the other is for confirm password) I want to have only one edittext and when after entering the password for first time and loose focus, well the below code is self-explanatory

passwordSgnup_et.setOnFocusChangeListener(new View.OnFocusChangeListener() {
                    @Override
                    public void onFocusChange(View v, boolean hasFocus) {
                        if(!hasFocus ) {
                            if (i <= 0) {
                                passwordSgnup_et.requestFocus();
                                cfmPasswordSgnup = Password;
                                passwordSgnup_et.getText().clear();
                                passwordSgnup_et.setHint("Confirm Password");
                                if (passwordSgnup_et.getText().toString() .equals( cfmPasswordSgnup)) {
                                    ParseUser userSignup = new ParseUser();
                                    userSignup.setUsername(Name);
                                    userSignup.setEmail(Email);
                                    userSignup.setPassword(Password);
                                    userSignup.put("Nickname",nickName);

Problem that I am facing is this. How can I know if the confirm password is entered and matches with the one entered the first time. I am confused there. Also to exit after the confirm password matches with the first password I am using the good old int i <= 0 logic anyway to improve this?

EDIT: This question was closed as a duplicate simply referring to another equals to question, MY QUESTION being is that, in the logic you can see that,

passwordSgnup_et.setHint("Confirm Password");
                                    if (passwordSgnup_et.getText().toString() .equals( cfmPasswordSgnup)) {

in between these two lines i need to take in the userinput (confirmpassword) to actually compare with the first password, that is what I am not able to get it.

One workaround taking a example with just one edittext

String password = null;
edittext.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        //First time edittext will be with default initialization so no tag will be set so u can check 
        if (!hasFocus){
            if (v.getTag() == null){
                //you require to put validations you want
                password = edittext.getText().toString();
                v.setTag("c");
                v.setText("");
                v.setHint("Confirm Password");
                v.requestFocus();
            }else if (((String)v.getTag()).equals("c"){
                //It is now confirm password field lost focus
            }
        }
    }
});

apart from this you can also implement the textwatcher and in afterTextChanged you can check

if (((String)v.getTag()).equals("c") {
   // So user has completed entering confirm password so you can put a check. 
}

I have not tested this code so it might have some code level issues/warning which you require to fix in actual implementation.

I think you want to use a TextWatcher .

TextView.addTextWatcher(...)

There are callbacks to get the info about when input is done. And check out OnFocusChangeListener interface as well!
