Android OnCreateOptionsMenu Artikel mit actionLayout funktioniert nicht

Question

Ich muss ein Layout in meinem Optionsmenü anzeigen.

menu.xml

<?xml version="1.0" encoding="utf-8"?> 
<menu xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item 
     android:id="@+id/action_likes" 
     android:showAsAction="never" 
     android:actionLayout="@layout/likes_layout"/> 

    <item 
     android:id="@+id/settings" 
     android:showAsAction="never" 
     android:title="Settings" 
     /> 
</menu> 

shape_notification.xml

<?xml version="1.0" encoding="utf-8"?> 
<shape xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="oval"> 
    <stroke android:color="#080808" android:width="2dp"/> 
    <corners android:radius="5dp" /> 
    <solid android:color="#85ea32"/> 
</shape> 

likes_layout.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="horizontal" android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

    <TextView 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:layout_weight="3" 
     android:id="@+id/likes" 
     android:linksClickable="false" 
     android:text="Likes" 
     android:gravity="center_vertical|center_horizontal" 
     android:textAppearance="?android:attr/textAppearanceLarge" /> 

    <Button 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_weight="5" 
     android:layout_gravity="center" 
     android:id="@+id/notif_count" 
     android:background="@drawable/shape_notification" 
     android:text="0" 
     android:textSize="16sp" 
     android:gravity="center" 
     android:padding="2dp" 
     android:singleLine="true" 
     android:layout_margin="5dp" 
     android:textColor="#fff"/> 
</LinearLayout> 

MainActivity.java

public class MainActivity extends AppCompatActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     MenuInflater inflater = getMenuInflater(); 
     inflater.inflate(R.menu.menu, menu); 

     return true; 
    } 
} 

Optionsliste ist sichtbar. Einstellungselement ist sichtbar, aber das Layout likes ist leer.

Hat jemand ein Aktionslayout für versteckte Objekte ausgeführt? Bitte helfen Sie mir

Answer 2

ändern android:actionLayout zu app:actionLayout so Ihre Menüpunkt Erklärung sollte aussehen wie

<item 
    android:id="@+id/action_likes" 
    app:showAsAction="never" 
    app:actionLayout="@layout/likes_layout"/> 

Aktualisiert:

Sie haben eine benutzerdefinierte Dropdown-Menü erstellen PopupWindow verwenden.

menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:app="http://schemas.android.com/apk/res-auto" 
xmlns:tools="http://schemas.android.com/tools" 
tools:context="project.com.example.MainActivity" 

> 
<item 
    android:id="@+id/item1" 
    android:title="@string/action_settings" 
    android:icon="@drawable/ic_launcher" 
    app:actionViewClass="android.widget.ImageButton" 
    app:showAsAction="always"> 

<menu> 
</menu> 
</item> 

</menu> 

MainActivity.java

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.menu_main, menu); 
    locButton = (ImageButton) menu.findItem(R.id.action_settings).getActionView(); 
    locButton.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      PopupWindow popupwindow_obj = popupDisplay(); 
      popupwindow_obj.showAsDropDown(locButton, -40, 18); 
     } 
    }); 
    return true; 
} 
    public PopupWindow popupDisplay() 
{ 

    final PopupWindow popupWindow = new PopupWindow(this); 

    LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

    View view = inflater.inflate(R.layout.listViewLayout, null); 
    ListView listView=(ListView)view.findViewById(R.id.list); 
    // populate listview with custom view which will be shown in drow down menu 
    popupWindow.setFocusable(true); 
    popupWindow.setWidth(WindowManager.LayoutParams.WRAP_CONTENT); 
    popupWindow.setHeight(WindowManager.LayoutParams.WRAP_CONTENT); 
    popupWindow.setContentView(view); 

    return popupWindow; 
} 

Hoffe, es hilft: peice Code, der es umgesetzt werden müssen archiviert werden.
