1つのナビゲーションバーを取り除き、アンドロイドでそれらを1つにマージするにはどうすればいいですか？

Question

私はAndroidがかなり新しいです。だから、このシリーの問題で私を助けてください 私は2つのナビゲーションバーを取得しています。私は両方の合併と1つのナビゲーションバー内のすべての要素を取得したいenter image description here これは、これは私のmanifest.xml

<?xml version="1.0" encoding="utf-8"?> 
    <manifest xmlns:android="http://schemas.android.com/apk/res/android" 
     package="info.androidhive.navigationdrawer"> 

     <uses-permission android:name="android.permission.INTERNET" /> 

     <application 
      android:allowBackup="true" 
      android:icon="@mipmap/ic_launcher" 
      android:label="@string/app_name" 
      android:supportsRtl="true" 
      android:theme="@style/AppTheme"> 
      <activity 
       android:name=".activity.LoginActivity" 
       > 
       <intent-filter> 
        <action android:name="android.intent.action.MAIN" /> 

        <category android:name="android.intent.category.LAUNCHER" /> 
       </intent-filter> 
      </activity> 
      <activity 
       android:name=".activity.AboutUsActivity" 
       android:label="@string/activity_title_about_us" /> 
      <activity 
       android:name=".activity.PrivacyPolicyActivity" 
       android:label="@string/activity_title_privacy_policy" /> 
      <activity android:name=".activity.MainActivity" 
       android:label="Main" 
       > 

      </activity> 
     </application> 

    </manifest>

そうのstyles.xml

<resources> 

をこのコードを入れない場合は、ナビゲーションバー

としてこれを意味します

    <item name="colorPrimaryDark">@color/colorPrimaryDark</item> 
    <item name="colorAccent">@color/colorAccent</item>

Answer 2

です。レイアウトからandroid.support.design.widget.AppBarLayoutを削除しないでください。代わりに、app:elevation="0dp"という属性を追加してください。あなたの最終的なレイアウトは次のようになります。

<android.support.design.widget.AppBarLayout 
      android:id="@+id/appBarLayout" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      app:elevation="0dp"> 
      ... 
</android.support.design.widget.AppBarLayout>
