请给我一个android 横向时间轴的demo

以下是一个简单的Android横向时间轴的Demo：

1. 在你的布局文件中添加RecyclerView：

<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

2. 创建一个数据类来保存时间轴中的数据：

data class TimeLineItem(
    val title: String,
    val description: String,
    val time: String
)

3. 创建一个RecyclerView的ViewHolder类：

class TimeLineViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
    private val titleTextView: TextView = itemView.findViewById(R.id.titleTextView)
    private val descriptionTextView: TextView = itemView.findViewById(R.id.descriptionTextView)
    private val timeTextView: TextView = itemView.findViewById(R.id.timeTextView)

    fun bind(item: TimeLineItem) {
        titleTextView.text = item.title
        descriptionTextView.text = item.description
        timeTextView.text = item.time
    }
}

4. 创建一个RecyclerView的Adapter类：

class TimeLineAdapter(private val items: List<TimeLineItem>) :
    RecyclerView.Adapter<TimeLineViewHolder>() {

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): TimeLineViewHolder {
        val view = LayoutInflater.from(parent.context)
            .inflate(R.layout.item_time_line, parent, false)
        return TimeLineViewHolder(view)
    }

    override fun onBindViewHolder(holder: TimeLineViewHolder, position: Int) {
        holder.bind(items[position])
    }

    override fun getItemCount(): Int {
        return items.size
    }
}

5. 在你的Activity或Fragment中初始化RecyclerView和Adapter：

val recyclerView = findViewById<RecyclerView>(R.id.recyclerView)
val layoutManager = LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false)
val items = listOf(
    TimeLineItem("Title 1", "Description 1", "Time 1"),
    TimeLineItem("Title 2", "Description 2", "Time 2"),
    TimeLineItem("Title 3", "Description 3", "Time 3"),
    TimeLineItem("Title 4", "Description 4", "Time 4"),
    TimeLineItem("Title 5", "Description 5", "Time 5")
)
val adapter = TimeLineAdapter(items)
recyclerView.layoutManager = layoutManager
recyclerView.adapter = adapter

6. 创建item_time_line.xml布局文件来定义每个时间轴项目的外观：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:padding="16dp">

    <View
        android:layout_width="4dp"
        android:layout_height="match_parent"
        android:background="@color/colorAccent" />

    <TextView
        android:id="@+id/titleTextView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Title"
        android:textSize="16sp" />

    <TextView
        android:id="@+id/descriptionTextView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Description"
        android:textSize="14sp" />

    <TextView
        android:id="@+id/timeTextView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Time"
        android:textSize="14sp" />

</LinearLayout>

这样就完成了一个简单的Android横向时间轴的实现。
