                });

            alertDialog.show();
        }

        else if(conpass.getText().toString()!= pass.getText().toString() ){

        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,即使我让两个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.谢谢.

您无法使用=或比较字符串!=,equals而是使用

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