Whats wrong with my query?

Can anyone see any errors in this code? I've checked to make sure the data has been written to the database. Every time I click the button it gives me the "Incorrect Password" text. It's probably something stupid that I'm overlooking. Any help is appreciated.

public void buttonWork() {
    button_credCheck.setOnClickListener(new View.OnClickListener() {
        String rpq = regPwdQuery().toString();
        String passInputStr = editText_pwdInput.getText().toString();

        @Override
        public void onClick(View v) {
            if (passInputStr == rpq) {
                Intent myIntent = new Intent(LogInActivity.this, FindInfoActivity.class);
                startActivity(myIntent);

            } else {
                Toast.makeText(LogInActivity.this, "Incorrect Password", Toast.LENGTH_LONG).show();
            }
        }
    });
}
