What can I do when I get a "cannot be resolved to a type" error?

I am trying to create a button on the mainActivity. Once clicked, it takes a user to a second view. However I keep getting an error saying that

onclick listener cannot be resolved to a type

and

the method set onclicklistener in the type view is not applicaible for the type of arguments

Below is the screenshot of the code:

Does anyone have any ideas?

Use class name you may have mistaken using xml name ... For example:

public void onClick(View v) {
    startActivity(new Intent(Second.this, Third.class));
}

You may have used "third.class"

public void onClick(View v) {
    startActivity(new Intent(Second.this, third.class));
}

This is because your source file is still missing the required imports for the classes you want to use.

You can always auto-add missing imports using Eclipse:

Ctrl+Shift+O

That way you don't have to guess which package you need to import.

Use 

this.insertionButton.setOnClickListener(new View.OnClickListener){});

and yes also import the above mentioned classes or press ctrl+shift+o
