Android解决RecyclerView的item宽度无法铺满的问题

不同手机上的展示情况

item 父布局的宽度设置为match_parent

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:layout_margin="@dimen/dp_4">

    <ImageView
        android:id="@+id/iv_movie_cover"
        android:layout_width="match_parent"
        android:layout_height="300dp"
        android:layout_gravity="center"
        android:background="@color/black" />

    <TextView
        android:id="@+id/tv_movie_search_key"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|center_horizontal"
        android:gravity="center"
        android:padding="@dimen/dp_4"
        android:textColor="@color/white" />

</FrameLayout>

适配器中，解决宽度不能铺满

View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_group_list, parent, false);//解决宽度不能铺满

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
//        View itemView = View.inflate(context,R.layout.item_recycle,null);
//        return new ViewHolder(itemView);
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_group_list, parent, false);//解决宽度不能铺满
        ViewHolder holder = new ViewHolder(view);
        return holder;

    }
