我想实现一个自定义的图标之一，我在底部菜单的外观
我已经创建了button_custom. xml

  1. <?xml version="1.0" encoding="utf-8"?>
  2. <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
  3.     android:layout_width="match_parent"
  4.     android:layout_height="match_parent">
  6.     <ImageButton
  7.         android:layout_width="40dp"
  8.         android:layout_height="40dp"
  9.         android:layout_gravity="center"
  10.         android:background="@drawable/button_border"
  11.         android:src="@drawable/ic_baseline_star_24"/>
  12. </FrameLayout>

我添加到我的菜单底部

  1. <item
  2.     android:id="@+id/kuponimeni"
  3.     android:title=""/>

我似乎不知道该在我的网站上添加什么V2MainFragment.java

我想请你帮忙
最终目标大致为enter image description here
我试过了

  1. MenuItem kuponimeniItem = navigation.getMenu().findItem(R.id.kuponimeni);
  2. View customView = LayoutInflater.from(requireContext()).inflate(R.layout.button_custom, null, false);
  3. FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
  4. layoutParams.gravity = Gravity.CENTER;
  5. customView.setLayoutParams(layoutParams);
  6. kuponimeniItem.setActionView(customView);

但我得到的只是空白，所以其他图标显示正常。button_custom应该在的地方是空的

无需为自定义按钮创建新的布局文件，只需将其嵌入到片段的布局文件中即可
一种方法是这样的

  1. <com.google.android.material.bottomnavigation.BottomNavigationView
  2.         android:id="@+id/bottomNavigationView"
  3.         android:layout_width="match_parent"
  4.         android:layout_height="wrap_content"
  5.         app:itemIconTint="@color/bnv_tab_item_foreground"
  6.         app:itemTextColor="@color/bnv_tab_item_foreground"
  7.         android:background="@color/colorFooter"
  8.         app:layout_constraintBottom_toBottomOf="parent"
  9.         app:menu="@menu/bottom_navigation_menu"
  10.         tools:ignore="MissingConstraints" >
  12.         <com.google.android.material.button.MaterialButton
  13.             android:id="@+id/btnAdc"
  14.             android:layout_width="76dp"
  15.             android:layout_height="wrap_content"
  16.             android:layout_gravity="center"
  17.             android:background="@menu/buttonadd"
  18.             android:gravity="center"
  19.             android:text="@string/add_btn"
  20.             android:textSize="25sp"
  22.             />
  23.     </com.google.android.material.bottomnavigation.BottomNavigationView>

您也可以使用约束来执行此操作。

  1. <ImageView
  2.             android:id="@+id/imageView"
  3.             android:layout_width="60dp"
  4.             android:layout_height="60dp"
  5.             android:elevation="2dp"
  6.             android:src="@drawable/ic_usernew"
  7.             app:layout_constraintBottom_toBottomOf="@+id/bot_nav_view"
  8.             app:layout_constraintEnd_toEndOf="parent"
  9.             app:layout_constraintStart_toStartOf="parent" />
  11.         <com.google.android.material.bottomnavigation.BottomNavigationView
  12.             android:id="@+id/bot_nav_view"
  13.             android:layout_width="0dp"
  14.             android:layout_height="wrap_content"
  15.             android:layout_marginStart="0dp"
  16.             android:layout_marginEnd="0dp"
  17.             android:background="@color/white"
  18.             app:elevation="0dp"
  19.             app:itemIconSize="20dp"
  20.             app:itemTextAppearanceActive="@style/BottomNavigationView.Active"
  21.             app:itemTextAppearanceInactive="@style/BottomNavigationView"
  22.             app:itemTextColor="@drawable/tab_icon_selector"
  23.             app:labelVisibilityMode="labeled"
  24.             app:layout_constraintBottom_toBottomOf="parent"
  25.             app:layout_constraintLeft_toLeftOf="parent"
  26.             app:layout_constraintRight_toRightOf="parent"
  27.             app:menu="@menu/bottom_nav_menu" />
  28.     </androidx.constraintlayout.widget.ConstraintLayout>

此组件将占用您在菜单项列表中指定的空白空间。
