Question

I just compiled and ran the hello world app and it worked. And I read through a bunch of stuff on the android documentation about the diff components of android and how it all works together. Now I want to make a few buttons which link to various actions.

For example, I want to make a button that goes to a new screen. Is there a tutorial for this sort of a thing? Or maybe someone could explain to me how to do that?

Thanks!

This is really simple. To make a button that goes to a new screen you should put a new button on your XML layout, and assign it an id. After you’ve done this, in your code, you need to do something like the following:

Button mButton = (Button) findViewById(R.id.mybutton);
mButton.setOnClickListener(new Button.OnClickListener() {  
    public void onClick(View v) {
      Intent myIntent = new Intent(CurrentActivity.this, NextActivity.class);
      CurrentActivity.this.startActivity(myIntent);
    }
});

Hope this helps you.

Also, be sure that the activity that you’re trying to start A) Exists, and B) is in your manifest.
