FragmentのButtonでfindViewByIdエラー

Posted at

Fragmentでレイアウトの中にあるButtonにクリック処理などしようとしたら、findViewByIdでエラー
調べてみたら、FragmentではfindViewByIdが定義されていないとの事。

その場合は、rootViewを使うとfindViewByIdが取得できるとか。
こんな感じ

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_main, container, false);
}

これでfindViewByIdができる
