What can i do please?

Definitely either you are missing name of the file or even file list_item.xml. So Insure that this layout file must be exist in your res/layout directory.

You are not including the correct R file. When you create a resource, like list_item, an identifier for it is added to the generated R file. This R file is located in the package of your application. There is also an Android R file, which is in a different package.

Make sure you have an import statement the imports the correct R file.

What is the name of your xml file? (Hint: it has to be list_item for R.layout.list_item to work)

Simply do this:

setContentView(R.layout.list_item);

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, msgList);

What you are probably trying to do is have a custom TextView in your ListView but it won't work like this.
