How to set my username and password in the code.?

Question

Button loginbuttonbutton = (Button) findViewById(R.id.btnLogin);
loginbuttonbutton.setOnClickListener(new View.OnClickListener() {
    public void onClick(View view) {
        if(inputEmail.getText().toString() == "EdEffort@ncat.edu" &&
           inputPassword.getText().toString() == "Steelers") {
            Intent myIntent = new Intent(view.getContext(),
                                         Host_Setting_PageActivity.class);
            startActivityForResult(myIntent, 0);
        } else {
            System.out.println("Username or password is incorrect");
        }
    }
});

That is my code and the application actually start but whenever I hit the login button the application closes.

Everyday there is atleast 1 question on SO on string comparison. — Kazekage Gaara, May 29 '12 at 17:22
@KazekageGaara - That's not unreasonable - it's an easy mistake to make, and the results don't often look like a string comparison error. For users coming from a language like C++ or C#, recognizing the error isn't in any way intuitive. — derekerdmann, May 29 '12 at 17:25
@derekerdmann yup. I know. That was just a follow up comment to the possible duplicate comment. I didn't mean to demoralize the OP in any way if that's what you thought it to be. :-) — Kazekage Gaara, May 29 '12 at 17:27

first use .equals() to compare strings.

== compares string refrences.Not value.

.equals() = compare strings character equality

if((inputEmail.getText().toString().equals("EdEffort@ncat.edu")&&inputPassword.getText().toString().equals("Steelers"))

And if force close than put logcat here..

use equals insead of == for String comparison

    loginbuttonbutton.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            if(inputEmail.getText().toString().equals("EdEffort@ncat.edu") && inputPassword.getText().toString().equals("Steelers") ){
            Intent myIntent = new Intent(YOUR_CURRENT_ACTIVITY.this, Host_Setting_PageActivity.class);
            startActivityForResult(myIntent, 0);
        }
            else{
                System.out.println("Username or password is incorrect");
            }
        }
    });

and make sure you are registering YOUR_CURRENT_ACTIVITY.this and Host_Setting_PageActivity.class both in manifest.xml

You should add

Host_Setting_PageActivity.class to your AndroidManifest

And also, you should compare strings always using .equals and not with "==" as "==" will really compare the instance of the string object and .equals will check the value of the string

dont use == method in if Condition but used .equals() method like as

if(inputEmail.getText().toString().equals("abc") && inputPassword.getText().toString().equals("abc") ){
----------your code here-----------
}
