本文实例为大家分享了RecyclerView实现横向滚动效果的具体代码，供大家参考，具体内容如下

布局文件

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".RecyclerViewActivity"> <androidx.recyclerview.widget.RecyclerView android:id="@+id/recyclerView_view" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_margin="8dp"/></LinearLayout>

Item

android:layout_width="100dp"android:layout_height="wrap_content"android:orientation="vertical"android:layout_margin="5dp"><ImageView android:id="@+id/iv_recyclerview_imag" android:layout_width="wrap_content" android:layout_height="100dp" /> <TextView android:id="@+id/tv_recyclerview_name" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="老虎" android:textSize="17sp" android:layout_gravity="center" android:textStyle="bold" android:padding="3dp"/></LinearLayout>

适配器

public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder> { private List<Animal> animalList; private int resource; public RecyclerViewAdapter(List<Animal> animalList, int resource) { this.animalList = animalList; this.resource = resource; } @NonNull @Override public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) { View itemView = LayoutInflater.from(parent.getContext()).inflate(resource,parent, false); ViewHolder holder = new ViewHolder(itemView); return holder; } @Override public void onBindViewHolder(@NonNull ViewHolder holder, int position) { Animal animal = animalList.get(position); holder.animalImag.setImageResource(animal.getImageId()); holder.animalName.setText(animal.getName()); } @Override public int getItemCount() { return animalList.size(); } static class ViewHolder extends RecyclerView.ViewHolder{ ImageView animalImag; TextView animalName; public ViewHolder(View itemView){ super(itemView); animalImag = itemView.findViewById(R.id.iv_recyclerview_imag); animalName = itemView.findViewById(R.id.tv_recyclerview_name); } }}

核心代码

public class RecyclerViewActivity extends AppCompatActivity { private List<Animal> animalList = new ArrayList<>(); private RecyclerView recyclerView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_recycler_view); recyclerView = findViewById(R.id.recyclerView_view); initAnimals(); LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this); linearLayoutManager.setOrientation(LinearLayoutManager.HORIZONTAL); recyclerView.setLayoutManager(linearLayoutManager); RecyclerViewAdapter adapter = new RecyclerViewAdapter(animalList,R.layout.recyclerview_item); recyclerView.setAdapter(adapter); } //初始化动物数据 private void initAnimals() { Animal daxaing = new Animal("大象", R.drawable.animal_one); animalList.add(daxaing); Animal shizi = new Animal( "袋鼠", R.drawable.animal_two); animalList.add(shizi); Animal daishu = new Animal("二哈", R.drawable.animal_three); animalList.add(daishu); Animal laohu = new Animal("狮子", R.drawable.animal_four); animalList.add(laohu); Animal zhu = new Animal("猪", R.drawable.animal_five); animalList.add(zhu); Animal songshu = new Animal("猴子", R.drawable.animal_six); animalList.add(songshu); Animal baozi = new Animal("豹子", R.drawable.animal_seven); animalList.add(baozi); Animal shayu = new Animal("鲨鱼", R.drawable.animal_eight); animalList.add(shayu); }}
