java - illegal initializer for 'java.lang.Integer'

问题描述

I was following grid view example in https://developer.android.com/guide/topics/ui/layout/gridview#example to try gridView. 

private Integer[] mThumbIds = {
        R.drawable.sample_2, R.drawable.sample_3,
        R.drawable.sample_4, R.drawable.sample_5,
        R.drawable.sample_6, R.drawable.sample_7,
        R.drawable.sample_0, R.drawable.sample_1,
        R.drawable.sample_2, R.drawable.sample_3,
        R.drawable.sample_4, R.drawable.sample_5,
        R.drawable.sample_6, R.drawable.sample_7,
        R.drawable.sample_0, R.drawable.sample_1,
        R.drawable.sample_2, R.drawable.sample_3,
        R.drawable.sample_4, R.drawable.sample_5,
        R.drawable.sample_6, R.drawable.sample_7
};

This part of code returns illegal initializer for 'java.lang.Integer' error. Android Studio also uses android.R.drawable unlike in this guide. Could it be outdated even though it says "Last updated December 20, 2018."? If so, how to initialize it correctly?
