call an activity on java android

Question

first of all, i'm a noob at java programing for android. Now, I have a button in the main layout that suppose to call an activity, now what do I write in the onClick method of the button? and I can't use onCreate in the activity that is being called, so what do I use in there? thanks

This is a very trivial task, it takes less effort to google this, than to ask a question here, for which you have already gotten suggestions that it may have already been asked. — Tomislav Markovski, Dec 25 '11 at 20:04

Put this code in the onClick method:

Intent intent = new Intent(getApplicationContext(), Activity.class);
startActivity(intent);

The system will start the activity Activity as soon as possible, which will lead to it's onCreate method being called.

This will start new activity.

Intent i = new Intent(getApplicationContext(), MyNewActivity.class);
startActivity(i);

`this` points to the Button context, you need to reference application context/activity. – Nikola Despotoski Dec 25 '11 at 20:04

You basically follow this pattern:

onClick() {
    Intent i = new Intent(this, <TargetIntent>.class);
    startActivity(i);
}

You need to create Intent first and pass your current activity instance and nect activity to it. Then call that activity through startActivity().

Intent i = new Intent(getApplicationContext(), MyNewActivity.class);

startActivity(i);
