Hi,

I am new to android development. I started learning android from this book. From the 2nd chapter of this book, i started coding To-Do List example in eclipse. When I completed the 6th step of the To-Do List Example, I am getting following errrors in eclipse.

ListView cannot be resolved to a type
EditText cannot be resolved to a type
R.id cannot be resolved

Please help me to resolve these errors and move forward with this example.

I am able to resolve the above errors. Eclipse is so intelligent that it advised me to import the corresponding package to resolve it. However I am getting a new error in step 8 of this example. The add method used is not getting compiled successfully.

The line of code with error is

Code:

todoItems.add(0, myEditText.getText(),toString());

The error is

The method add(int, String) in the type ArrayList<String> is not applicable for the arguments (int,Editable,String)

Please help me to resolve this error.

It's quite a simple fix, you have a comma where you should have a period just before the toString(). The code should be:

Code:

todoItems.add(0, myEditText.getText().toString());
