android studio实现一个简易横向滑动页面

首先，在布局文件中定义一个水平滑动的RecyclerView：

<android.support.v7.widget.RecyclerView
    android:id="@+id/recycler_view"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal" />

然后，在Activity中设置RecyclerView的LayoutManager为LinearLayoutManager，并设置其方向为水平：

RecyclerView recyclerView = findViewById(R.id.recycler_view);
recyclerView.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false));

接下来，创建一个适配器并设置给RecyclerView：

public class MyAdapter extends RecyclerView.Adapter<MyViewHolder> {

    private List<Integer> mData;

    public MyAdapter(List<Integer> data) {
        mData = data;
    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_layout, parent, false);
        return new MyViewHolder(view);
    }

    @Override
    public void onBindViewHolder(MyViewHolder holder, int position) {
        holder.bindData(mData.get(position));
    }

    @Override
    public int getItemCount() {
        return mData.size();
    }
}

public class MyViewHolder extends RecyclerView.ViewHolder {

    private TextView mTextView;

    public MyViewHolder(View itemView) {
        super(itemView);
        mTextView = itemView.findViewById(R.id.text_view);
    }

    public void bindData(int data) {
        mTextView.setText(String.valueOf(data));
    }
}

RecyclerView recyclerView = findViewById(R.id.recycler_view);
recyclerView.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false));
List<Integer> data = new ArrayList<>();
for (int i = 0; i < 10; i++) {
    data.add(i);
}
MyAdapter adapter = new MyAdapter(data);
recyclerView.setAdapter(adapter);

最后，在item_layout布局文件中定义一个TextView用于显示数据：

<TextView
    android:id="@+id/text_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="24sp" />

这样就实现了一个简易的横向滑动页面。
