Andloid Studio 3.6.3  Spinner等の選択値の保存方法|teratail

Android Studioを初めて使用する初心者です。サンプルプログラムからSpinner, seekBar、RadioButton、RadioButtonをコードイングしてその値をheight.texに表示することを確認できましたが、アプリ再起動時に選択した値がheight.

Android Studioを初めて使用する初心者です。

サンプルプログラムからSpinner, seekBar、RadioButton、RadioButtonをコードイングしてその値をheight.texに表示することを確認できましたが、アプリ再起動時に選択した値がheight.texには反映しますがSpinner, seekBar、RadioButtonそれぞれにも設定値が反映されるようにしたいです。


下記のサンプルコードで再起動時に設定値ががSpinner, seekBar、RadioButtonに反映されるにはどのようなコーデイングが必要なのでしょうか方法を教えていただきたく宜しくお願い致します。
