How to fix: Resources$NotFoundException while calling Toast

I wanted to display the Selecteditemposition (number of clicked item in a Listview) in a Toast when an item is clicked in my Listview, but any method in this event crashes.

This is the crash report:

        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:858)

And this is the code:

list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    public void onItemClick(AdapterView<?> parent, View view,
                            int position, long id) {
        boolean co = true;
        int lineNumber = listview.getSelectedItemPosition();
        Toast.makeText(MainActivity.this, lineNumber, Toast.LENGTH_SHORT).show();
    }
});

What am I doing wrong?

lineNumber is an integer, so you are using this overload of makeText():

makeText(Context context, int resId, int duration)

Which expects an integer string resource id, so lineNumber is considered a string resource id, which of course is not so it can't be found.

Instead what you should be doing is convert lineNumber to string and use this overload of makeText():

makeText(Context context, CharSequence text, int duration)

So do this:

Toast.makeText(MainActivity.this, String.valueOf(lineNumber), Toast.LENGTH_SHORT).show();
