        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //setting up the button references
        Button jokeD = (Button) findViewById(R.id.jokeoftheday);
        Button jokeC = (Button) findViewById(R.id.jokecatagories);

        jokeD.setOnClickListener(new View.OnClickListener() {

            @Override

                // TODO Auto-generated method stub
                startActivity(new Intent(Menu.this, JokeOfTheDay.class));

            }
        });

        jokeC.setOnClickListener(new View.OnClickListener() {

            @Override

                Intent s = new Intent("com.Tripp.thebasics.JOKECATAGORIES");
                startActivity(s);
            }
        });

    @Override
    protected void onPause() {

        // TODO Auto-generated method stub
        super.onPause();
    }
}

Answer 1

Help with creating an intent such that you can call an activity when a button is clicked. Also need help declaring an activity in a manifest file:

 myBtn.setOnClickListener() {
        public void onClick() {
            Intent intent = new Intent(this, SecondActivity.class);
            startActivity(intent);
        }
    }

Answer 2

1. create seperate xml and java files for new activity.

2. Create on click listener like below for the button. Button.setOnClickListener() { public void onClick() { Intent myintent = new Intent(this, newactivity.class); startActivity(myintent); } }

3.add new activity on android manifest.xml file.

<application>

`<activity android:name=".classname" ></activity>`

</application

Answer 3

jokeD.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

            startActivity(new Intent(this,    JokeOfTheDay.class));

            }
         });

And make sure you have your new class in the AndroidManifest.xml:

<activity
            android:name=".youractivitypackagename.JokeOfTheDay"
            android:label="JokeOfTheDay" >
</activity>

EDIT: Take a look here for a better explanation of how to declare an activity in the Manifest, as it depends on how you declare the package: http://developer.android.com/guide/topics/manifest/manifest-intro.html .

If your package for your class is, for example, com.example.project.Test, then you should have the following, within the tags:

<activity
                android:name="com.example.project.Test.JokeOfTheDay"
                android:label="JokeOfTheDay" >
 </activity>
