私はAndroidのデータバインディング機能について読んでいました。私はネストされたレイアウトからビューをバインドしようとしていました。私の活動は、アンドロイドのデフォルトテンプレートDrawerMenuActivity
で、レイアウト内にネストされたcontent_my_activity
レイアウトです。入れ子になったレイアウトでAndroid DataBindingを設定する方法
私は3つの自動生成バインディングクラスを持っています。 MyActivityBinding
,AppBarMyActivityBinding
およびContentMyActivityBinding
。
MyActivity.java
MyActivityBinding activityBinding;
AppBarMyActivityBinding appBarBinding;
ContentMyActivityBinding contentBinding;
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
activityBinding = DataBindingUtils.setContentView(this,
R.layout.activity_my_activity);
appBarBinding = DataBindingUtils.setContentView(this,
R.layout.app_bar_my_activity);
contentBinding = DataBindingUtils.setContentView(this,
R.layout.content_my_activity);
setName();
}
private void setName(){
contentBinding.setFirstName("Omkar");
}
しかし、それは以下のようにRuntimeExceptionをスロー:

どのように私はcontent_my_activity
からビューを結合しない
は、私は以下のように、すべての3クラスを初期化しようとしましたMyActivity.javaクラスでは、どんな助けにも感謝しています。
ありがとうございました。
