Android TimeLine 时间节点轴的实现实例代码

整理文档，搜刮出一个Android TimeLine 时间节点轴的实现实例代码，稍微整理精简一下做下分享。

效果图

具体实现 (RecyclerView)

Adapter

package com.haoren.timeline;import android.content.Context;import android.support.v7.widget.RecyclerView;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.ImageView;public class TimeLineAdapter extends RecyclerView.Adapter<TimeLineAdapter.HorizontalVh> {  private Context context;  //时间节点数  private int nodeNum = 0;  //当前到达节点  private int currentNode = 1;  public TimeLineAdapter(Context context, int nodeNum) {    this.context = context;    this.nodeNum = nodeNum;  }  @Override  public HorizontalVh onCreateViewHolder(ViewGroup parent, int viewType) {    View view = LayoutInflater.from(context).inflate(R.layout.time_line, null, false);    HorizontalVh vh = new HorizontalVh(view);    return vh;  }  @Override  public void onBindViewHolder(HorizontalVh holder, int position) {    if (position < currentNode) {      //当前节点之前的全部设为已经经过      holder.point.setImageResource(R.mipmap.point_select);      holder.lineLeft.setBackgroundResource(R.color.colorPrimary);      holder.lineRight.setBackgroundResource(R.color.colorPrimary);    }    // 去掉左右两头的分支    if (position == 0) {      holder.lineLeft.setVisibility(View.INVISIBLE);    }    if (position == nodeNum - 1) {      holder.lineRight.setVisibility(View.INVISIBLE);    }  }  @Override  public int getItemCount() {    return nodeNum;  }    public void setCurrentNode(int currentNode) {    this.currentNode = currentNode;    this.notifyDataSetChanged();  }  class HorizontalVh extends RecyclerView.ViewHolder {    private ImageView point;    private View lineLeft, lineRight;    public HorizontalVh(View itemView) {      super(itemView);      this.point = (ImageView) itemView.findViewById(R.id.point);      this.lineLeft = itemView.findViewById(R.id.line_left);      this.lineRight = itemView.findViewById(R.id.line_right);    }  }}
