Android 网格布局管理器未将元素居中

Question

我在约束布局中有以下回收器视图（非常简单）

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context=".activities.PokemonFavoritesActivity"
tools:showIn="@layout/activity_pokemon_favorites">

<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/rv_pokemon_favorites"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_margin="2dp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>

这是我初始化 Recycler View 的方法：

  private void initializeRecyclerViewComponents() {
    favoritesRecyclerView = findViewById(R.id.rv_pokemon_favorites);
    layoutManager = new GridLayoutManager(this, 4);
    favoritesRecyclerView.setLayoutManager(layoutManager);
    pokemonFavoritesAdapter = new PokemonFavoritesAdapter(this, favoritePokemon);
    pokemonFavoritesAdapter.setClickListener(this);
    favoritesRecyclerView.setAdapter(pokemonFavoritesAdapter);
}

这里是 item_layout:

<?xml version="1.0" encoding="utf-8"?>
<com.mikhaellopez.circularimageview.CircularImageView 
 xmlns:android="http://schemas.android.com/apk/res/android"
 android:id="@+id/civ_pokemon_favorite"
 android:layout_width="100dp"
 android:layout_height="100dp" />

但是，正如您在图片中看到的那样，视图没有“居中”（与开始相比，每一行的末尾有很多额外的边距）我怎样才能使 4 列居中以具有相同的开始和结束间距？

Answer 1

尝试将项目视图包裹在线性布局中，并将图像居中放置。这应该可以解决它。
