如何在NavigationView中添加自定义布局并设计我的创建自定义NavigationView使用材质设计，我想把我的抽屉图标放在右边，文字左边是这样的

Answer 1

我搜索太多，这是我的经验，工作正常

首先创建标题的布局。它的名称是nav_header_main.xml，然后将其放在layouts的{​​{1}}个文件夹中，并将此代码放入其中..

res

然后我将其包含为<?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="@dimen/nav_header_height" android:background="@drawable/header" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" android:theme="@style/ThemeOverlay.AppCompat.Dark" android:gravity="top"> <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:padding="16dp"> <de.hdodenhof.circleimageview.CircleImageView android:id="@+id/cv_nave_profile_image" android:layout_width="@dimen/nav_profile_image" android:layout_height="@dimen/nav_profile_image" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:src="@drawable/profile" /> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_toLeftOf="@id/cv_nave_profile_image" android:layout_alignParentTop="true" android:padding="@dimen/activity_horizontal_margin" android:orientation="vertical" > <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/tv_nav_name" android:textStyle="bold" android:typeface="sans" android:textColor="#ffffff" android:gravity="right" android:layout_gravity="right" android:text="رخداد جدید" android:paddingBottom="5dp" android:textSize="@dimen/body" /> </LinearLayout> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:typeface="sans" android:textColor="#ffffff" android:id="@+id/tv_nav_phone" android:layout_alignParentLeft="true" android:text="0370077315" /> </RelativeLayout> </LinearLayout> 的子项，对于菜单项我使用NavigationView来显示菜单和图标，以便RecyclerView

NavigationView

只需记住将<android.support.design.widget.CoordinatorLayout android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true" tools:context="spydroid.ir.dorobar.Activities.SearchActivity"> <android.support.design.widget.AppBarLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:theme="@style/AppTheme.AppBarOverlay"> <android.support.v7.widget.Toolbar android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" android:background="?attr/colorPrimary" app:popupTheme="@style/AppTheme.PopupOverlay"> </android.support.v7.widget.Toolbar> </android.support.design.widget.AppBarLayout> <include layout="@layout/content_search" /> <android.support.design.widget.FloatingActionButton android:id="@+id/fab" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="bottom|end" android:layout_margin="@dimen/fab_margin" android:src="@android:drawable/ic_dialog_email" /> </android.support.design.widget.CoordinatorLayout> <android.support.design.widget.NavigationView android:id="@+id/nav_view" android:layout_width="fill_parent" android:layout_height="match_parent" android:layout_gravity="right" android:fitsSystemWindows="true" android:layout_marginLeft="@dimen/nav_margin" > <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <include layout="@layout/nav_header_main" /> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent"> <android.support.v7.widget.RecyclerView android:id="@+id/drawer_slidermenu" android:layout_width="fill_parent" android:layout_height="match_parent" android:layout_marginTop="16dp"/> </RelativeLayout> </LinearLayout> </android.support.design.widget.NavigationView> 放入NavigationView

然后我使用DrawerLayout和ImageView此布局为菜单项创建布局，此名称为TextView，其代码位于此处

card_drawer_item.xml

然后我为此布局创建<?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="48dp"> <ImageView android:id="@+id/drawer_icon" android:layout_width="25dp" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_marginLeft="12dp" android:layout_marginRight="12dp" android:src="@drawable/ic_about" android:layout_centerVertical="true" /> <TextView android:id="@+id/drawer_text" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_toLeftOf="@id/drawer_icon" android:minHeight="?android:attr/listPreferredItemHeightSmall" android:textAppearance="?android:attr/textAppearanceListItemSmall" android:gravity="center_vertical" android:typeface="sans" android:paddingRight="40dp"/> </RelativeLayout> 文件夹。

ViewHolder

现在我将菜单项的文本定义为字符串数组，并在public class DrawerItemHolder extends RecyclerView.ViewHolder { public ImageView itemIcon; public TextView itemText; public DrawerItemHolder(View itemView) { super(itemView); itemIcon= (ImageView) itemView.findViewById(R.id.drawer_icon); itemText= (TextView) itemView.findViewById(R.id.drawer_text); } }

中的菜单中包含菜单图标

strings.xml

然后我们只需要<string-array name="drawer_items"> <item>setting</item> <item>add record</item> <item>ads</item> <item>about</item> <item>call</item> <item>help</item> <item>privacy</item> </string-array> <array name="drawers_icons"> <item>@drawable/ic_action_settings</item> <item>@drawable/ic_plus</item> <item>@drawable/ic_ads</item> <item>@drawable/ic_about</item> <item>@drawable/ic_phone</item> <item>@drawable/ic_help</item> <item>@drawable/ic_policy</item> </array> 这样的

Adapter

每件事都没问题。刚才我们必须在Activity中设置NavigationView。

public class DrawerItemAdapter extends RecyclerView.Adapter<DrawerItemHolder> {

    // slide menu items
    private List<DrawerItem> items;
    private List<Integer> drawerIcons;
    public DrawerItemAdapter(List<DrawerItem>  items) {
        super();
        this.items = items;


    }

    @Override
    public DrawerItemHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View itemView = LayoutInflater.
                from(parent.getContext()).
                inflate(R.layout.card_drawer_item, parent, false);

        return new DrawerItemHolder(itemView);
    }

    @Override
    public void onBindViewHolder(DrawerItemHolder holder, int position) {
        holder.itemIcon.setImageResource(items.get(position).getIconId());
        holder.itemText.setText(items.get(position).getText());
    }

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