RecyclerView实现横向滚动效果

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);
 }

}
