最近开发的app中要用到时间轴这东西，需要实现的效果如下：

想想这个东西应该可以用listview实现吧。然后最近就模拟着去写了：

首先写 listview的item的布局:

listview_item.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"
android:orientation="vertical"
android:paddingRight="20dp" > <View
android:id="@+id/view_0"
android:layout_width="1dp"
android:layout_height="25dp"
android:layout_below="@+id/layout_1"
android:layout_marginLeft="71dp"
android:background="#A6A6A6" /> <View
android:id="@+id/view_1"
android:layout_width="1dp"
android:layout_height="25dp"
android:layout_below="@+id/layout_2"
android:layout_marginLeft="71dp"
android:background="#A6A6A6" /> <TextView
android:id="@+id/show_time"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/view_1"
android:layout_marginLeft="30dp"
android:text="测试数据"
android:textSize="12dp" /> <ImageView
android:id="@+id/image"
android:layout_width="15dp"
android:layout_height="15dp"
android:layout_below="@+id/view_1"
android:layout_marginLeft="65dp"
android:src="@drawable/timeline_green" /> <View
android:id="@+id/view_2"
android:layout_width="1dp"
android:layout_height="100dp"
android:layout_below="@+id/image"
android:layout_marginLeft="71dp"
android:background="#A6A6A6" /> <RelativeLayout
android:id="@+id/relative"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/image"
android:layout_marginTop="-20dp"
android:layout_toRightOf="@+id/image"
android:background="@drawable/timeline_content"
android:padding="10dp" > <ImageView
android:id="@+id/image_1"
android:layout_width="60dp"
android:layout_height="60dp"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:layout_marginLeft="5dp"
android:src="@drawable/bg_green_circle_smic" /> <TextView
android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:ellipsize="end"
android:maxEms=""
android:paddingLeft="5dp"
android:singleLine="true"
android:text="测试数据"
android:textSize="12sp" /> </RelativeLayout></RelativeLayout>

接下来就是写listview的adapter了：

TimelineAdapter.java

package com.example.timelinetext.test;import java.util.List;
import java.util.Map;import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;public class TimelineAdapter extends BaseAdapter { private Context context;
private List<Map<String, Object>> list;
private LayoutInflater inflater; public TimelineAdapter(Context context, List<Map<String, Object>> list) {
super();
this.context = context;
this.list = list;
} @Override
public int getCount() { return list.size();
} @Override
public Object getItem(int position) {
return position;
} @Override
public long getItemId(int position) {
return position;
} @Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder = null;
if (convertView == null) {
inflater = LayoutInflater.from(parent.getContext());
convertView = inflater.inflate(R.layout.listview_item, null);
viewHolder = new ViewHolder(); viewHolder.title = (TextView) convertView.findViewById(R.id.title);
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
} String titleStr = list.get(position).get("title").toString(); viewHolder.title.setText(titleStr); return convertView;
} static class ViewHolder {
public TextView year;
public TextView month;
public TextView title;
}
}
