NavigationView common attributes and basic usage

Effect picture:

Common attributes:

android:layout_gravity: left/startMeans sliding out from the left, rightmeans sliding out from the right

android:background: Background color (except headerbackground color)

<com.google.android.material.navigation.NavigationView
    android:id="@+id/nv_sides_lip"
    android:layout_width="320dp"
    android:layout_height="match_parent"                                           
    android:layout_gravity="left"
    app:headerLayout="@layout/layout_sidelip"
    app:menu="@menu/menu_sidelip"
    app:itemTextColor="@color/nv_item_text"
    android:background="@drawable/bac_top_user"                                                       app:itemTextAppearance="@style/navigation_item_text_size"
    />

How to modify the icon size, text size, icon and text spacing of Menu in NavigationView

1. Modify 图标大小:

In style.xmlthe definition of a <dimen>rewrite attribute design_navigation_icon_size. xmlFile header needs to be importedtools

<dimen name="design_navigation_icon_size" tools:override="true">图标具体的大小</dimen>

2. Modify 文字大小:

In style.xmla defined<style>

<style name="navigation_item_text_size">
    <item name="android:textSize">文字具体的大小</item>
</style>

3. Modify the space between the icon and the text:

In style.xmlthe definition of a <dimen>rewrite attribute design_navigation_icon_padding. The header of the xml file needs to be importedtools

<dimen name="design_navigation_icon_padding" tools:override="true">具体间距大小</dimen>

Basic usage (Java code):

private DrawerLayout dl_sides_lip; // 侧滑栏布局
private NavigationView nv_sides_lip;  // 侧滑栏内布局

dl_sides_lip = findViewById(R.id.dl_sideslip_layout);
nv_sides_lip = findViewById(R.id.nv_sides_lip);

// 设置监听器，NavigationView.OnNavigationItemSelectedListener接口
nv_sides_lip.setNavigationItemSelectedListener(this);

// 保留原 icon 的颜色，不然自己图标的颜色都不生效
nv_sides_lip.setItemIconTintList(null);

// 实现接口方法
/**
 * 侧滑栏中 NavigationView 的子项点击事件
 * @param menuItem 菜单子项
 * @return
 */
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
    
    
   switch (menuItem.getItemId()){
    
    
       case R.id.nv_about:
            Toast.makeText(getContext(),menuItem.getTitle().toString(),Toast.LENGTH_SHORT).show();
            // 关闭侧滑栏
            dl_sides_lip.closeDrawer(Gravity.LEFT);
            return true;
       case R.id.nv_1:
            Toast.makeText(getContext(),menuItem.getTitle().toString(),Toast.LENGTH_SHORT).show();
            dl_sides_lip.closeDrawer(Gravity.LEFT);
            return true;
       case R.id.nv_2:
            Toast.makeText(getContext(),menuItem.getTitle().toString(),Toast.LENGTH_SHORT).show();
            dl_sides_lip.closeDrawer(Gravity.LEFT);
            return true;
       default:
            break;
    }
   return false;
}
