Android UI:ListView -- SimpleAdapter

SimpleAdapter是扩展性最好的适配器，可以定义各种你想要的布局，而且使用很方便。

layout ：

<?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="horizontal"> <ListView android:layout_width="match_parent" android:layout_height="wrap_content" android:divider="#7f00"　　　　//分割线 android:dividerHeight="2dp" android:id="@+id/listview_sample"/></LinearLayout>

header layout：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:orientation="vertical" android:layout_width="match_parent"android:layout_height="match_parent"><ImageView android:layout_width="match_parent" android:layout_height="wrap_content" android:src="@mipmap/ic_launcher"/></LinearLayout>

自定义布局 item：

<?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="horizontal"> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_margin="3px" android:id="@+id/img"/> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical"> <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:textSize="16sp" android:id="@+id/title"/> <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/info" android:textSize="16sp"/> </LinearLayout></LinearLayout>

Java 代码：

public class SampleAdapterActivity extends Activity { private ListView mListview; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.sampleadapter_layout); mListview = (ListView) findViewById(R.id.listview_sample); SimpleAdapter adapter = new SimpleAdapter(this, getData(), //数据来源 R.layout.item_listview, //对应item view new String[]{"img","title","info"}, //data 中对应值 new int[]{R.id.img,R.id.title,R.id.info}); //填充layout位置 mListview.setHeaderDividersEnabled(true); //是否显示头view 的分割线 View header = View.inflate(this,R.layout.listview_header,null); View footer = View.inflate(this,R.layout.listview_header,null); mListview.addHeaderView(header); //添加头部view mListview.addFooterView(footer); //添加底部view mListview.setAdapter(adapter); } @Override protected void onResume() { super.onResume(); } private List<? extends Map<String,?>> getData() { List<Map<String,Object>> items = new ArrayList<Map<String, Object>>(); for (int i = 0; i < 5; i++) { Map<String,Object> item = new HashMap<String,Object>(); item.put("img",R.mipmap.ic_launcher); item.put("title","title -- " + i ); item.put("info","info -- " + i ); items.add(item); } return items; }}
