時間軸，顧名思義就是將發生的事件按照時間順序羅列起來，給用戶帶來一種更加直觀的體驗。物流順序就是一個時間軸
其實，整個時間軸還是可以當做一個ListView處理，只是在Adapter中的佈局要花點心思。好了，廢話不說，看代碼。
1、整個效果就是一個ListView,ListView的每個條目的佈局如下
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/listview"
android:cacheColorHint="@null"
android:divider="@null"
></ListView>
</LinearLayout>
2、TimelineAdapter 的代碼如下：
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);
viewHolder.show_time = (TextView) convertView.findViewById(R.id.show_time);
viewHolder.image=(ImageView) convertView.findViewById(R.id.image);
viewHolder.view_1= convertView.findViewById(R.id.view_1);
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
String titleStr = list.get(position).get("title").toString();
String timeStr = list.get(position).get("show_time").toString();
viewHolder.title.setText(titleStr);
viewHolder.show_time.setText(timeStr);
if (position==0) {
viewHolder.view_1.setVisibility(View.GONE);
}
return convertView;
}
static class ViewHolder {
public TextView year;
public TextView month;
public ImageView image;
public TextView title;
View view_2;
View view_1;
public TextView show_time;
}
}
3、listview_item的佈局如下：
<?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="#000000"
android:orientation="vertical"
android:paddingRight="20dp" >
<View
android:id="@+id/view_1"
android:layout_width="1dp"
android:layout_height="20dp"
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="06:00"
android:textColor="#ffffff"
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/callmsgsafe" />
<View
android:id="@+id/view_2"
android:layout_width="1dp"
android:layout_height="90dp"
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="80dp"
android:layout_below="@+id/image"
android:layout_marginTop="-10dp"
android:layout_toRightOf="@+id/image"
android:background="@drawable/reg_shape"
android:layout_marginLeft="10dp" >
<TextView
android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:paddingLeft="5dp"
android:textStyle="bold"
android:text="19:00"
android:textSize="12sp" />
</RelativeLayout>
</RelativeLayout> 4、MainActivity實現代碼：
public class MainActivity extends Activity {
private ListView listView;
List<String> data ;
private TimelineAdapter timelineAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_listview);
listView = (ListView) this.findViewById(R.id.listview);
listView.setDividerHeight(0);
timelineAdapter = new TimelineAdapter(this, getData());
listView.setAdapter(timelineAdapter);
}
private List<Map<String, Object>> getData() {
List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
Map<String, Object> map = new HashMap<String, Object>();
map.put("title", "時間軸");
map.put("show_time", "08:30");
list.add(map);
map = new HashMap<String, Object>();
map.put("title", "時間軸");
map.put("show_time", "09:30");
list.add(map);
map = new HashMap<String, Object>();
map.put("title", "時間軸");
map.put("show_time", "14:30");
list.add(map);
map = new HashMap<String, Object>();
map.put("title", "時間軸");
map.put("show_time", "20:45");
list.add(map);
map = new HashMap<String, Object>();
map.put("title", "時間軸");
map.put("show_time", "23:00");
list.add(map);
map = new HashMap<String, Object>();
map.put("title", "時間軸");
map.put("show_time", "00:30");
list.add(map);
return list;
}
} 實現效果如下圖
