So fügen Sie Symbole in der Navigationsleiste hinzu?

Question

Ich brauche dich Hilfe :) Ich habe bereits meine App geschrieben, aber jetzt muss ich Nav Schublade hinzufügen. Ich habe eine Nav-Schublade hinzugefügt, aber ich kann nicht verstehen, wo ich meine Icons platzieren soll. Ich mag Symbole setzen Text links von nav Artikeln wie folgen aus:

Bilder "one"

pics2 "zwei"

pics3 "drei"

hier mein Java-Code ist Einstellungen. java

Answer 1

Danke euch allen. Ich habe die Antwort in einem anderen Forum gefunden. cyberforum.ru

Hier gehen wir.

Sie benötigen Ihren eigenen Adapter, wo Sie Ihre Symbole und Etiketten anbringen und dann an Ihre Ansicht binden.

So Klasse MenuItem mit Daten, Icons und Titel

public class MenuItem { 
    private String title; 
    private int imageId; 

    public String getTitle() { 
     return title; 
    } 

    public void setTitle(String title) { 
     this.title = title; 
    } 

    public int getImageId() { 
     return imageId; 
    } 

    public void setImageId(int imageId) { 
     this.imageId = imageId; 
    } 
} 

Übertragen Sie Ihre erstellte Klasse Adpater und menuHolder zu erstellen, die

import android.content.Context; 
    import android.view.LayoutInflater; 
    import android.view.View; 
    import android.view.ViewGroup; 
    import android.widget.ArrayAdapter; 
    import android.widget.ImageView; 
    import android.widget.TextView; 

    import java.util.List; 

    /** 
    * Created by vklamm on 08.04.2016. 
    * transfer hier MenuItem class 
    * create Menu holder and bind it to view 
    */ 
    public class MyAdapter extends ArrayAdapter<MenuItem> { 

     private int resource; 
     private List<MenuItem> data; 
     private Context context; 
     private MenuHolder menuHolder; 

     public MyAdapter(Context context, int resource, Context context1) { 
      super(context, resource); 
      context = context1; 
     } 

     public MyAdapter(Context context, int resource, List<MenuItem> data) { 
      super(context, resource, data); 
      this.context = context; 
      this.resource = resource; 
      this.data = data; 
     } 

     @Override 
     public View getView(int position, View convertView, ViewGroup parent) { 
      if(convertView==null){ 
       LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
       convertView = layoutInflater.inflate(resource,parent,false); 

       menuHolder = new MenuHolder(); 

       //create drawer_list_item layout where ours icons and labels are 
       menuHolder.menuItemImg = (ImageView) convertView.findViewById(R.id.menuItemImg); 
       menuHolder.menuItemTitle = (TextView) convertView.findViewById(R.id.menuItemTitle); 
       convertView.setTag(menuHolder); 
      }else { 
       menuHolder = (MenuHolder) convertView.getTag(); 
      } 

      MenuItem menuItem = data.get(position); 
      if(menuItem!=null){ 
       menuHolder.menuItemImg.setImageResource(menuItem.getImageId()); 
       menuHolder.menuItemTitle.setText(menuItem.getTitle()); 
      } 

      return convertView; 
     } 
     //created class for binding our icons and texts from view 
     public class MenuHolder { 
      ImageView menuItemImg; 
      TextView menuItemTitle; 
     } 
    } 

modifites/Wechsel drawer_list_item.xml zu

zum Ansehen bindet

<?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"> 

    <ImageView 
     android:layout_width="50dp" 
     android:layout_height="50dp" 
     android:id="@+id/menuItemImg" /> 

    <TextView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:textAppearance="?android:attr/textAppearanceMedium" 
     android:text="Medium Text" 
     android:id="@+id/menuItemTitle" /> 
</LinearLayout> 

jetzt zu Settings.class

hinzufügen

Answer 2

Sie müssen Ihre eigenen Adapter, definieren das Layout es Elemente erstellen, so dass es auf das Symbol und Text enthält, wie Sie wollen, und dann Stellen Sie es als Adapter für Ihre Liste ein.

So müssen Sie Ihre drawer_list_item.xml ändern, um ein horizontales LinearView zu enthalten, mit dem Symbol ImageView und das Label TextView.

Hier ist eine Implementierung ich für eine meiner Projekte haben, die genau das tut, was Sie tun müssen:

    private void setUpDrawerToggle() { 
     final DrawerLayout drawerLayout = (DrawerLayout) findViewById(R.id.drawer_container); 
     mDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, getToolbar(), 
      R.string.drawer_open, R.string.drawer_close); 
     drawerLayout.addDrawerListener(mDrawerToggle); 
    }

Answer 3

drawer_list_item das Layout Ihrer Listenansicht ist .. ein Imageview vor dem Textview hinzufügen .. Erstellen Sie ein Array von Bildern wie mplanettitles, aber machen Sie ein Array von Zeichnungsdateien .. es wird wie int aussehen [] mplaneimages = [r.drawable.etwas] dann erstellen Sie einen benutzerdefinierten Adapter .. übergeben Sie dann das String-Array und int-Array von Bilder zu Ihrem Adapter dann Sie setzen es in den Adapter
