</LinearLayout>

CreateAppointment.java

package com.examples;

import android.app.Activity;
import android.os.Bundle;

public class CreateAppointment extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.createapp);
    }

}

code for the button to start a new activity

public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.simple_calendar_view);
    Button createAppointment = (Button)findViewById(R.id.crtApp);
    createAppointment.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

            // TODO Auto-generated method stub
            startActivity(new Intent("android.intent.action.CREATEAPP"));           
        }
    });
}

<Button /> needs to have the android:onClick="your method name here"attribute

and Java code should look something like this

public void methodName(View view)
{
  Intent intent = new Intent(this, ClassName.class);
  startActivity(intent)
}

Have you declared the activity in the menifest file?

Besides try:

Intent i = new Intent();
i.setClassName(pkgname, activity name);
startActivity(i);

if I understand well, you want to start an activity on button pressed.Then you should have something like this :

createAppointment.setOnClickListener(new View.OnClickListener() {
     @Override
     public void onClick(View v) {
     Intent intent = new Intent(your_context, CreateAppointment.class);
     startActivity(intent);
     }
 });

hope it helps! (for better understanding post your error log :) )

startActivity(new Intent(getBaseContext(), CreateAppointment.class));

And also like kailoon said, "Check to make sure the activity is in the AndroidManifest.xml file."
