Android NavigationView Menü Umschalttaste

Question

Ich möchte Umschalttaste oder mindestens Kontrollkästchen in meinem NavigationView für die Funktion der Kontrolle Benachrichtigungen von ihm (ein/aus).

Das Layout mit Hilfe der Datei "menu.xml" durchgeführt.

Ich habe versucht, checkable="true" hinzuzufügen, aber es zeigt nichts. Wie implementiert man es?

<group android:checkableBehavior="single"> 
     <item 
      android:id="@+id/profile" 
      android:icon="@drawable/ic_account_grey600_48dp" 
      android:title="@string/profile" /> 
     <item 
      android:id="@+id/tutorial" 
      android:icon="@drawable/ic_help_grey600_48dp" 
      android:title="@string/tutorial" /> 
<item 
    android:id="@+id/checkable_menu" 
    android:checkable="true" 
    android:title="@string/haircut_notifications" /> 

    </group> 

    <group 
     android:id="@+id/menu_bottom" 
     android:checkableBehavior="none"> 
     <item 
      android:id="@+id/nav_share" 
      android:icon="@drawable/ic_share_variant_grey600_48dp" 
      android:title="@string/share" /> 
     <item 
      android:id="@+id/selfie_videos" 
      android:icon="@drawable/ic_camera_front_variant_grey600_48dp" 
      android:title="@string/selfie_videos" /> 
    </group> 

</menu> 

EDIT:

Kleines Beispiel bei Google M mit Knebel wie ich erreichen möchte.

Haben Sie eine Idee, das zu tun?

Answer 1

Sie könnten versuchen mit der App: actionLayout = "@ layout/item", item.xml ist, wo Sie Ihre Schaltfläche wechseln.

<menu xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto"> 

<item android:title="@string/settings_info"> 
     <menu> 

    <item android:id="@+id/nav_number" 
      android:icon="@drawable/ic_room" 
      android:title="@string/number" 
      app:actionLayout="@layout/item"/> 

    </item> 

</menu> 


/*How to handle the click event*/ 
@Override public boolean onNavigationItemSelected(MenuItem item) { 

// Handle navigation view item clicks. 
    switch (item.getItemId()){ 
     case R.id.nav_network: 
      startActivity(new Intent(this, NetworkActivity.class)); break; 
    } 

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); 
    drawer.closeDrawer(GravityCompat.START); 
    return true; 
} 

Answer 2

statt Ansicht Verwendung Recycler Menü, so dass Sie viel mehr Kontrolle über die Elemente. Der folgende Code ist getestet und funktioniert.

Dies ist löschte:

Schritt eins: Artikel Layouts erstellen:

item_normal.xml

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

<ImageView 
    android:id="@+id/image" 
    android:layout_marginLeft="16dp" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:src="@mipmap/ic_launcher" /> 

<TextView 
    android:id="@+id/text" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_gravity="center_vertical" 
    android:layout_marginLeft="16dp" 
    android:text="Title" /> 

</LinearLayout> 

nichts Besonderes, einfach nur Bild und ein Text

Schritt 2 : Für unser Toggle-Layout können wir item_toggle.xml

erstellen

item_toggle.xml

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

<TextView 
    android:id="@+id/textCustom" 
    android:layout_marginLeft="16dp" 
    android:layout_centerVertical="true" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="Notifications" /> 

<ToggleButton 
    android:layout_marginRight="16dp" 
    android:id="@+id/toggleButton" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentEnd="true" 
    android:layout_alignParentRight="true" 
    android:text="New ToggleButton" /> 
</RelativeLayout> 

Schritt 3: Damit können Adapter für unsere Recycler Ansicht erstellen, die in unserer Navigationsansicht

CustomAdapter.java

public class CustomAdapter extends RecyclerView.Adapter { 

String Tag = CustomAdapter.class.getSimpleName(); 

private final int NORMAL_VIEW = 88; // code for normal view type 
private final int CUSTOM_VIEW = 99; //code for loader type 

private Context context; 
private ArrayList<Model> listingData = new ArrayList<>(); 

public CustomAdapter(Context context) { 
    this.context = context; 
} 

@Override 
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 

    LayoutInflater inflater = LayoutInflater.from(parent.getContext()); 

    if (viewType == NORMAL_VIEW) { 

     View normalView = inflater.inflate(R.layout.item_normal, parent, false); 
     return new NormalItem(normalView); 

    } else if (viewType == CUSTOM_VIEW) { 

     View customView = inflater.inflate(R.layout.item_toogle, parent, false); 
     return new CustomItem(customView); 
    } else return null; // unknown type. 
} 

@Override 
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) { 

    if (holder instanceof NormalItem) { 
     // normal list item. 
     ((NormalItem) holder).textView.setText(listingData.get(position).getName()); 
     ((NormalItem) holder).icon.setImageResource(R.mipmap.ic_launcher); 

    } else if (holder instanceof CustomItem) 
    { 
     ((CustomItem) holder).textViewToggle.setText("On"); 
     ((CustomItem) holder).textViewToggle.setText("Notifications"); 
    } 
} 

@Override 
public int getItemCount() { 
    return listingData.size(); 
} 

@Override 
public int getItemViewType(int position) { 

    if (position == 3) return CUSTOM_VIEW; 
    else return NORMAL_VIEW; 
} 

public class NormalItem extends RecyclerView.ViewHolder { 

    ImageView icon; 
    TextView textView; 

    public NormalItem(View itemView) { 
     super(itemView); 

     icon = (ImageView) itemView.findViewById(R.id.image); 
     textView = (TextView) itemView.findViewById(R.id.text); 

    } 
} 

public class CustomItem extends RecyclerView.ViewHolder { 

    ToggleButton toggleButton; 
    TextView textViewToggle; 

    public CustomItem(View itemView) { 
     super(itemView); 

     toggleButton = (ToggleButton) itemView.findViewById(R.id.toggleButton); 
     textViewToggle = (TextView) itemView.findViewById(R.id.textCustom); 

    } 
} 


/** 
* method to update the adapter and notify the adapter item by item 
* 
* @param data data to be updated. 
*/ 
public void updateAdapter(ArrayList<Model> data) { 

    try { 
     for (Model item : data) { 
      listingData.add(item); 
      notifyItemInserted(getItemCount() - 1); 
     } 
    } catch (Exception e) { 
     Log.e(Tag, e.toString() + ""); 
    } 

} 
} 

Schritt 4 sein wird: ein erstellen activity_main.xml

activity_main.xml

<?xml version="1.0" encoding="utf-8"?> 
<android.support.design.widget.CoordinatorLayout    xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:fitsSystemWindows="true" 
tools:context=".main.MainActivity"> 


<android.support.v4.widget.DrawerLayout 
    android:id="@+id/drawerLayout" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:fitsSystemWindows="true" 
    tools:openDrawer="start"> 

    <LinearLayout 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:orientation="vertical"> 

     <include layout="@layout/toolbar" /> 

    </LinearLayout> 

    <android.support.design.widget.NavigationView 
     android:id="@+id/navigationView" 
     android:layout_width="wrap_content" 
     android:layout_height="match_parent" 
     android:layout_gravity="start"> 

     <android.support.v7.widget.RecyclerView 
      android:layout_marginTop="16dp" 
      android:id="@+id/recyclerView" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      android:scrollbars="vertical" /> 


    </android.support.design.widget.NavigationView> 
</android.support.v4.widget.DrawerLayout> 

Schritt 5: Ermöglicht eine einfache Klasse erstellen

Model.java unsere Daten

public class Model { 

public String getName() { 
    return name; 
} 

public void setName(String name) { 
    this.name = name; 
} 

public int getItem() { 
    return item; 
} 

public void setItem(int item) { 
    this.item = item; 
} 

String name; 
int item; 
} 

Schritt 6 zu halten:

<?xml version="1.0" encoding="utf-8"?> 
<android.support.v7.widget.Toolbar  xmlns:android="http://schemas.android.com/tools" 
xmlns:app="http://schemas.android.com/apk/res/android" 
app:id="@+id/toolbar" 
android:elevation="4dp" 
app:layout_width="match_parent" 
app:layout_height="wrap_content" 
app:background="?attr/colorPrimary" 
app:popupTheme="@style/ThemeOverlay.AppCompat.Light" 
app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" 
android:background="?attr/colorPrimary" 
/> 

letzter Schritt: Erstellen MainActiivty .klasse

Hauptaktivität.Klasse

public class MainActivity extends AppCompatActivity { 

private DrawerLayout drawerLayout; 
private RecyclerView recyclerView; 
private ArrayList<Model> data; 



@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 
    getSupportActionBar().setTitle("Custom Nav "); 
    drawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout); 
    NavigationView navigationView = (NavigationView) findViewById(R.id.navigationView); 

    ActionBarDrawerToggle mToogle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.app_name, R.string.app_name); 
    drawerLayout.addDrawerListener(mToogle); 
    mToogle.syncState(); 

    recyclerView = (RecyclerView) findViewById(R.id.recyclerView); 
    LinearLayoutManager manager = new LinearLayoutManager(this); 
    recyclerView.setLayoutManager(manager); 

    CustomAdapter adapter = new CustomAdapter(this); 
    recyclerView.setAdapter(adapter); 

    data = new ArrayList<>(); 

    Model item1 = new Model(); 
    item1.setName("Option 1"); 
    item1.setItem(R.mipmap.ic_launcher); 

    Model item2 = new Model(); 
    item2.setName("Option 2"); 
    item2.setItem(R.mipmap.ic_launcher); 

    Model item3 = new Model(); 
    item3.setItem(R.mipmap.ic_launcher); 
    item3.setName("Option 3"); 

    Model item4 = new Model(); 
    item4.setItem(R.mipmap.ic_launcher); 
    item4.setName("Option 4"); 


    data.add(item1); 
    data.add(item2); 
    data.add(item3); 
    data.add(item4); 
    adapter.updateAdapter(data); 
} 

} 

Sie können Header hinzufügen und die Benutzeroberfläche nach Ihren Bedürfnissen polieren. Ich hoffe es hilft. Glückliche Codierung.
