Hii,
I am just trying to switch to next activity.Infact,anything
written in onClick() is giving error on call to setOnClickListener.
Here is code:
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent intent = new
Intent(Login.this, ForgetPassword.class);
startActivity(intent);
}
});

[android-developers] Re: problem with buttonListener
The log output you just sent gives you the answer. At line 24 of your
helloone activity, in the onCreate() method, you are trying to
dereference a null pointer. Apparently, you did not retrieve the
button correctly.
