android的liveview装载数据

设置布局

<?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" >        <TextView        android:id="@+id/itemsTitle"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="center_vertical"        android:paddingLeft="10dip"        android:paddingTop="5dip"        android:textColor="@color/gray_black"        android:textSize="18dip" />    <TextView        android:id="@+id/itemsText"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_below="@+id/itemsTitle"        android:gravity="left"        android:paddingBottom="2dip"        android:paddingLeft="10dip"        android:textColor="@color/gray"        android:textSize="15dip" /></RelativeLayout>

　从MAP的集合取数据

//获取数据Intent intent = getIntent();Bundle bundle = intent.getExtras();SerializableMaplist SerializableMaplist = (SerializableMaplist) bundle.get("listdata");maplist =SerializableMaplist.getMap();  //填充数据ListView mListView = (ListView)findViewById(R.id.listview);//使用自定义的AdapterMyListViewAdapter myListViewAdapter = new MyListViewAdapter(this, maplist,R.layout.list_items,new String[] {"rqsj","s","f" ,"JLR"}, new int[] {R.id.itemsTitle,R.id.itemsText }); mListView.setAdapter(myListViewAdapter);

　　自定义类MyListViewAdapter
