mainactivity.java

private void displayview(int position) {     fragment fragment = null;     string title = getstring(r.string.app_name);     switch (position) {         case 0:             fragment = new homefragment();             title = getstring(r.string.nav_item_home);             break;         case 1:             fragment = new friendsfragment();             title = getstring(r.string.nav_item_friends);             break;         case 2:             fragment = new messagesfragment();             title = getstring(r.string.nav_item_notifications);             break;         case 3:             fragment = new calculatorfragment();             title = getstring(r.string.nav_item_calculator);             break;         case 4:             fragment = new moviefragment();             title = getstring(r.string.nav_item_listview);             break;         case 5:             fragment = new tabfragment();             title = getstring(r.string.nav_item_testabs);         default:             break;     }      if (fragment != null) {         fragmentmanager fragmentmanager = getsupportfragmentmanager();         fragmenttransaction fragmenttransaction = fragmentmanager.begintransaction();         fragmenttransaction.replace(r.id.container_body, fragment);         fragmenttransaction.commit();          // set toolbar title         getsupportactionbar().settitle(title);     } } 

navdrawweritem.java

public class navdraweritem { private boolean shownotify; private string title; private int icon;  public navdraweritem() {  }  public navdraweritem(boolean shownotify, string title, int icon) {     this.shownotify = shownotify;     this.title = title;     this.icon = icon; }  public boolean isshownotify() {     return shownotify; }  public void setshownotify(boolean shownotify) {     this.shownotify = shownotify; }  public string gettitle() {     return title; }  public int geticon(){     return this.icon; }  public void settitle(string title) {     this.title = title; }  public void seticon(int icon){     this.icon = icon; } 

easiest way use navigationview in support lib.

see link demo

you have create menu file item navigation

<group android:checkablebehavior="single">      <item         android:id="@+id/inbox"         android:checked="false"         android:icon="@drawable/ic_inbox_black"         android:title="@string/inbox_string" />      <item         android:id="@+id/starred"         android:checked="false"         android:icon="@drawable/ic_star_black"         android:title="@string/starred_string" />      <item         android:id="@+id/sent_mail"         android:checked="false"         android:icon="@drawable/ic_send_black"         android:title="@string/sent_mail_string" />      <item         android:id="@+id/drafts"         android:checked="false"         android:icon="@drawable/ic_drafts_black"         android:title="@string/draft_string" />       <item         android:id="@+id/allmail"         android:checked="false"         android:icon="@drawable/ic_email_black"         android:title="@string/all_mail_string" />     <item         android:id="@+id/trash"         android:checked="false"         android:icon="@drawable/ic_delete_black"         android:title="@string/trash_string" />     <item         android:id="@+id/spam"         android:checked="false"         android:icon="@drawable/ic_error_black"         android:title="@string/spam_string" />  </group>
