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

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">

android:id="@+id/recyclerView_view"

android:layout_width="match_parent"

android:layout_margin="8dp"/>

Item

android:layout_width="100dp"

android:layout_height="wrap_content"

android:orientation="vertical"

android:layout_margin="5dp">

android:id="@+id/iv_recyclerview_imag"

android:layout_width="wrap_content"

android:layout_height="100dp" />

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"/>

适配器

public class RecyclerViewAdapter extends RecyclerView.Adapter {

private List animalList;

private int resource;

public RecyclerViewAdapter(List 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 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);

}

}
