将标题添加到导航抽屉

我一直在试图向我的导航抽屉添加标题/部分，但不幸的是没有成功。我看了这些问题在这里StackOverflow的：将标题添加到导航抽屉

Android Navigation Drawer ListView Headers

这里就是我想要做的事。我想制作一个导航抽屉（每行中有图标和文本），并且在一些标题之间（例如在项目2和项目6中）。如果你告诉我要在代码中添加/更改什么，以便使它成为可能，我会很感激。（但是更详细的内容是“覆盖函数X和覆盖函数Y”，因为我是初学者，而且我的时间不好试图实现它到我的代码→我已经尝试过6次今天，但它崩溃）。

希望你得到你的答案或问题已经解决。但是，如果没有，你可以尝试从https://github.com/AndGitRepo/NavDrawer/tree/master/NavDrawer

的例子你可以创建列表项的界面。然后在两个类中实现该接口：一个用于列表项，第二个用于列表的Section/Header项。

public class NavMenuSection implements NavDrawerItem { 

public static final int SECTION_TYPE = 0; 
private int id; 
private String label; 

private NavMenuSection() { 
} 

public static NavMenuSection create(int id, String label) { 
    NavMenuSection section = new NavMenuSection(); 
    section.setLabel(label); 
    return section; 
} 

@Override 
public int getType() { 
    return SECTION_TYPE; 
} 

public String getLabel() { 
    return label; 
} 

public void setLabel(String label) { 
    this.label = label; 
} 

@Override 
public boolean isEnabled() { 
    return false; 
} 

public int getId() { 
    return id; 
} 

public void setId(int id) { 
    this.id = id; 
} 

@Override 
public boolean updateActionBarTitle() { 
    return false; 
}

}

而另一类列表项是

public static final int ITEM_TYPE = 1 ; 

private int id ; 
private String label ; 
private int icon ; 
private boolean updateActionBarTitle ; 

private NavMenuItem() { 
} 

public static NavMenuItem create(int id, String label, String icon, boolean updateActionBarTitle, Context context) { 
    NavMenuItem item = new NavMenuItem(); 
    item.setId(id); 
    item.setLabel(label); 
    item.setIcon(context.getResources().getIdentifier(icon, "drawable", context.getPackageName())); 
    item.setUpdateActionBarTitle(updateActionBarTitle); 
    return item; 
} 

@Override 
public int getType() { 
    return ITEM_TYPE; 
} 

public int getId() { 
    return id; 
} 

public void setId(int id) { 
    this.id = id; 
} 

public String getLabel() { 
    return label; 
} 

public void setLabel(String label) { 
    this.label = label; 
} 

public int getIcon() { 
    return icon; 
} 

public void setIcon(int icon) { 
    this.icon = icon; 
} 

@Override 
public boolean isEnabled() { 
    return true; 
} 

@Override 
public boolean updateActionBarTitle() { 
    return this.updateActionBarTitle; 
} 

public void setUpdateActionBarTitle(boolean updateActionBarTitle) { 
    this.updateActionBarTitle = updateActionBarTitle; 
}

现在更新适配器代码

public class NavDrawerAdapter extends ArrayAdapter<NavDrawerItem>{ 

private LayoutInflater inflater; 

public NavDrawerAdapter(Context context, int textViewResourceId, NavDrawerItem[] objects) { 
    super(context, textViewResourceId, objects); 
    this.inflater = LayoutInflater.from(context); 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    View view = null ; 
    NavDrawerItem menuItem = this.getItem(position); 
    if (menuItem.getType() == NavMenuItem.ITEM_TYPE) { 
     view = getItemView(convertView, parent, menuItem); 
    } 
    else { 
     view = getSectionView(convertView, parent, menuItem); 
    } 
    return view ; 
} 

public View getItemView(View convertView, ViewGroup parentView, NavDrawerItem navDrawerItem) { 

    NavMenuItem menuItem = (NavMenuItem) navDrawerItem ; 
    NavMenuItemHolder navMenuItemHolder = null; 

    if (convertView == null) { 
     convertView = inflater.inflate(R.layout.navdrawer_item, parentView, false); 
     TextView labelView = (TextView) convertView 
       .findViewById(R.id.navmenuitem_label); 
     ImageView iconView = (ImageView) convertView 
       .findViewById(R.id.navmenuitem_icon); 

     navMenuItemHolder = new NavMenuItemHolder(); 
     navMenuItemHolder.labelView = labelView ; 
     navMenuItemHolder.iconView = iconView ; 

     convertView.setTag(navMenuItemHolder); 
    } 

    if (navMenuItemHolder == null) { 
     navMenuItemHolder = (NavMenuItemHolder) convertView.getTag(); 
    } 

    navMenuItemHolder.labelView.setText(menuItem.getLabel()); 
    navMenuItemHolder.iconView.setImageResource(menuItem.getIcon()); 

    return convertView ; 
} 

public View getSectionView(View convertView, ViewGroup parentView, 
     NavDrawerItem navDrawerItem) { 

    NavMenuSection menuSection = (NavMenuSection) navDrawerItem ; 
    NavMenuSectionHolder navMenuItemHolder = null; 

    if (convertView == null) { 
     convertView = inflater.inflate(R.layout.navdrawer_section, parentView, false); 
     TextView labelView = (TextView) convertView 
       .findViewById(R.id.navmenusection_label); 

     navMenuItemHolder = new NavMenuSectionHolder(); 
     navMenuItemHolder.labelView = labelView ; 
     convertView.setTag(navMenuItemHolder); 
    } 

    if (navMenuItemHolder == null) { 
     navMenuItemHolder = (NavMenuSectionHolder) convertView.getTag(); 
    } 

    navMenuItemHolder.labelView.setText(menuSection.getLabel()); 

    return convertView ; 
} 

@Override 
public int getViewTypeCount() { 
    return 2; 
} 

@Override 
public int getItemViewType(int position) { 
    return this.getItem(position).getType(); 
} 

@Override 
public boolean isEnabled(int position) { 
    return getItem(position).isEnabled(); 
} 


private static class NavMenuItemHolder { 
    private TextView labelView; 
    private ImageView iconView; 
} 

private class NavMenuSectionHolder { 
    private TextView labelView; 
}}

然后从主要活动中添加列表项的部分和/或项目

NavDrawerItem[] menu = new NavDrawerItem[] { 
      NavMenuSection.create(100, "Logged in user details"), 
      //NavMenuItem.create(101,"List/Detail (Fragment)", "navdrawer_friends", true, this), 
      //NavMenuItem.create(102, "Airport (AsyncTask)", "navdrawer_airport", false, this), 
      //NavMenuSection.create(200, "General"), 
      NavMenuItem.create(202, "Rate this app", "drawer_shadow", false, this), 
      NavMenuItem.create(203, "Nav", "drawer_shadow", false, this), 
      NavMenuItem.create(204, "Quit", "drawer_shadow", false, this)}; 

    NavDrawerActivityConfiguration navDrawerActivityConfiguration = new NavDrawerActivityConfiguration(); 
    navDrawerActivityConfiguration.setMainLayout(R.layout.activity_nav_drawer); 
    navDrawerActivityConfiguration.setDrawerLayoutId(R.id.drawer_layout); 
    navDrawerActivityConfiguration.setLeftDrawerId(R.id.left_drawer); 
    navDrawerActivityConfiguration.setNavItems(menu); 
    navDrawerActivityConfiguration.setDrawerShadow(R.drawable.drawer_shadow);  
    navDrawerActivityConfiguration.setDrawerOpenDesc(R.string.drawer_open); 
    navDrawerActivityConfiguration.setDrawerCloseDesc(R.string.drawer_close); 
    navDrawerActivityConfiguration.setBaseAdapter(
     new NavDrawerAdapter(this, R.layout.navdrawer_item, menu));
