Activity/Fragment周りのデータ受け渡しの方法まとめです。
Javaです。

ActivityからActivity

送信元のActivity

Intent intent = new Intent(this, ToActivity.class);
intent.putExtra("NAME", "太郎");
startActivity(intent);
finish();

送信先のActivity(ToActivity)

@Override
protected void onCreate(final Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);

  Intent intent = getIntent();
  String name = intent.getStringExtra("NAME");
}

ポイントはbundleが不要なところです。

ActivityからFragment

        .add(android.R.id.content, fragment)

  @Override

  Bundle args = getArguments();

  }
}

ポイントはbundleを使うところです。

Android Studioで実行したアプリがエラーで落ちる時に、落ちる直前で止まってくれる方法です。

以下の画像の中のCreat breakpointのテキストをクリックすればOKです。

昔調べたけどやり方分からなくて、ログ見てたらたまたま気付いた。
もっと早くに知りたかった。。

ImageVIewにDataBindingする方法です。

まずはレイアウトファイル
hoge.xml

1
2

<ImageView
    android:id="@+id/icon_menu"/>

次にFragment or Activityファイル
hoge.kt

1

binding.iconMenu.setImageResource(R.drawable.ic_action_hoge)

以上。

めちゃくちゃハマったけど最終的にシンプルに書けば良いだけだった。。
ググると複雑なやり方が出てくるのはどういうアレなんだろう。
これが正式なやり方じゃないかもだけど、とりあえず動いたので良かった。

2022/5/26追記
公式ページが十分分かりやすいのでこれ見れば十分ですね。。

以下、元の文章。

kotlinでFragmentのViewBindingを導入する方法です。

    }

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)

        binding.walkThroughButton1.setOnClickListener(this)

    override fun onClick(view: View?) {

        val intent = Intent(activity, SettingActivity::class.java)
        startActivity(intent)

以上です。

解決策

おそらくこのエラーの原因はtargetSDKバージョンが31以上であり、かつJDKバージョンが11より小さいことです。
以下の通りにすれば解決します。

• JDKバージョンを11以上にする
• Android Studio 2020.3（もしくはそれより最新版）をインストールする

JDKバージョンを11以上にするには、最新のAndroid Studioをダウンロードして、Android Studio → Preferences → Build Tools → GradleのGradle JDKを11以上に指定してください。
