In my program the App crashes when I write it like this and if I write @Override bevor the onClick(View v) it is an error too. Whats wrong?

[karter61]

When I write the same as you, I get this error:

btn1.setOnClickListener(this);

(with setOnClickListener underlined)

Can you help me?

@karter61 change "this" to "null"

[valgriz]

[sonictwin]

Instead of making the button pop-up a toast message, how do I make the buttons link to different pages in the layout.

much better than the first way. I got stuck with the first way also because the comp I was on could only handle API 7 and down. now I'm on a comp with 4gb of RAM and a real processor. but because no error message comes up in eclipse letting you know that, I was sort of guessing until I got on a better machine. anyway, I'm loving the videos and learning alot. this is a godsend actually. keep em coming!

When I write the same as you, I get two errors.

I get one in this:

public class HelloWorldActivity extends Activity implements OnClickListener {

And one in this:

btn1.setOnClickListener(this);

Can you help me?

Try setting your API level to 10, aka (gingerbread 2.3.3). Also make sure your SDKs and Eclipse are up to date.
