Question

I ran the HelloWorld android app and now I moved on to making buttons and stuff like that. I am able to create the buttons in the layout xml and all that, but I ran into some confusion over Eclipse not recognizing my Intent declarations.

Here is a snippet of code:

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

The CurrentActivity and NextActivity classes do not seem to be recognized and Eclipse and it doesn’t give me the option to automatically create the import statements for it.

What is the package that these classes are in? Is it an issue of some things not recognized? Or some package that needs to be installed/downloaded? Whats the best practice way to handle such a situation?

Also, do I need to add listeners if I already added the buttons to the layout?

Thanks!

I believe CurrentActivity and NextActivity are just being used as example names for classes for launching an activity in whatever code snippet you were looking at.

CurrentActivity should be the name of whatever the Activity class is that you’re launching the new activity from, and NextActivity would be the name of some new Activity class that you want to navigate to next.
