java - android中的密码验证确认

Question

我有这个 Activity ，我想在其中验证确认密码字段。这是我的代码-:

nt.setOnClickListener(new OnClickListener() { 

    public void onClick(View v) { 

         if(email.getText().toString().equals("")){
            AlertDialog alertDialog = new AlertDialog.Builder(Registration.this).create();
            alertDialog.setTitle("oops!");
            alertDialog.setMessage("E-mail field is empty");
            alertDialog.setButton("Ok",
            new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                      //dismiss the dialog  
                    }
                });
            alertDialog.show();
        }
        else if(pass.getText().toString().equals("")){

            AlertDialog alertDialog = new AlertDialog.Builder(Registration.this).create();
            alertDialog.setTitle("oops!");
            alertDialog.setMessage("Password  field is empty");
            alertDialog.setButton("Ok",
            new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                      //dismiss the dialog  
                    }
                });

            alertDialog.show();
        }

        else if(conpass.getText().toString()!= pass.getText().toString() ){
            AlertDialog alertDialog = new AlertDialog.Builder(Registration.this).create();
            alertDialog.setTitle("oops!");
            alertDialog.setMessage("Passwords do not match");

        else{

            String mail = email.getText().toString();

            String pas = pass.getText().toString();

            String fname = name.getText().toString();

            String dateob = dob.getText().toString();

            String add12 = address.getText().toString();

            String tow = city.getText().toString();

            String zip1 = zip.getText().toString();

            String mob = mobile.getText().toString();

            String phn = phone.getText().toString();

            Intent per = new Intent(getApplicationContext(), Register2.class);
            per.putExtra("email", mail);
            per.putExtra("name", fname);
            per.putExtra("password", pas);
            per.putExtra("mobile", mob);
            per.putExtra("phone", phn);
            per.putExtra("address", add12);
            per.putExtra("zip", zip1);
            per.putExtra("city", tow);
            per.putExtra("dateofbirth", dateob);
            startActivity(per);
        }

    }
});  

现在即使我的两个 edittext 字段相同，它仍然显示密码不匹配的警告对话框。请在这里帮助我。提前致谢。

您不能使用= 或!= 来比较字符串，而是使用equals

else if(!conpass.getText().toString().equals(pass.getText().toString()) )
