Android时光轴

时间轴，顾名思义就是将一些事件或者事物等按照时间顺序罗列起来，给用户带来一种更加直观的体验。京东和淘宝等的物流顺序就是一个时间轴

前言：​Android中使用RecyclerView实现时光轴，代码简单易懂.

效果如下：​

开发环境：AndroidStudio2.1.2+gradle-2.10

添加依赖(gradle中)：

compile 'com.android.support:recyclerview-v7:23.0.0'

activity中：

public class MainActivity extends AppCompatActivity {

private RecyclerView recyclerView;
private List<TimeInfo > list=null;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    initLayout();
}
private void initLayout(){
    recyclerView= (RecyclerView) findViewById(R.id.recyclerView);
    recyclerView.setLayoutManager(new LinearLayoutManager(this));
    recyclerView.setHasFixedSize(true);
    recyclerView.setItemAnimator(new DefaultItemAnimator());
    list=new ArrayList<>();
    for(int i=0;i<10;i++){
        list.add(new TimeInfo());
    }
    TimelineAdapter mAdapter = new TimelineAdapter(this, list);
    recyclerView.setAdapter(mAdapter);
}

}

adapter中:

public class TimelineAdapter extends  RecyclerView.Adapter<TimelineAdapter.ViewHolder> {

private static final int ALPHA = 100;

private List<TimeInfo> list=null;

private Context context;
public TimelineAdapter(Context context,List<TimeInfo> list) {
    this.list=list;
    this.context=context;

}
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View v = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.v7_item_timeline, null);

    return new ViewHolder(v);
}

@Override
public void onBindViewHolder(ViewHolder holder, int position) {
    holder.textView.setText("2016-08-10\n10：20");
    int color = context.getResources().getColor(R.color.colorAccent);
    holder.civ.setFillColor(color);
    holder.civ.setBorderColor(ColorUtils.setAlphaComponent(color, ALPHA));
    holder.img.setBackgroundResource(R.mipmap.ic_zhihu_logo);
    holder.item_timeline_view.setBackgroundResource(list.size()%2==0?R.color.colorAccent:R.color.colorPrimary);
}

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

public static class ViewHolder extends RecyclerView.ViewHolder {
    TextView textView;
    CircleImageView civ;
    ImageView img;
    View item_timeline_view;
    public ViewHolder(View v) {
        super(v);
        textView = (TextView) v.findViewById(R.id.item_timeline_time);
        civ= (CircleImageView) v.findViewById(R.id.item_timeline_icon_bg);
        img= (ImageView) v.findViewById(R.id.item_timeline_icon);
        item_timeline_view=v.findViewById(R.id.item_timeline_view);
    }
}

}
