ナビゲーションドロワーは、複数の活動のためのアイテムでの作業ではない

Question

私は私の新しい次のようになりますNavigationDrawerActivity.java内のナビゲーションドロワーのためのすべての私のコードをコピーここは電子activity_navigation_drawer.xmlmenu Ressourceファイルです。それは私が何も起こらないのナビゲーションでアイテムをクリックしているという事実に大きなまで働いて

<?xml version="1.0" encoding="utf-8"?> 
 
<menu xmlns:android="http://schemas.android.com/apk/res/android"> 
 

 
    <group android:checkableBehavior="single">

      android:id="@+id/nav_home"

    </item> 
 

 
</menu>

。私が間違っていることを示唆していますか？

あなたはプロジェクト全体hereを見つけることができます。

Answer 1

最初に、メニュー項目をどのように作成するのか、リソースメニューファイルで作成するのか、単純に配列をロードするのかについてのリファレンスやコードを投稿してください。もし配列を使用しているのであれば、メニュー項目を作成します。このような

何か：あなたはどうするかコード化されていないため

<?xml version="1.0" encoding="utf-8"?> 
<menu xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item android:id="@+id/new_game" 
      android:icon="@drawable/ic_new_game" 
      android:title="@string/new_game" 
      android:showAsAction="ifRoom"/> 
    <item android:id="@+id/help" 
      android:icon="@drawable/ic_help" 
      android:title="@string/help" /> 
</menu>
