Android_ListView详解

①ArrayAdapter演示

在ListView的使用中，可以使用ArrayList来填充列表。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context=".MainActivity" >    <ListView        android:id="@+id/listview"        android:layout_width="match_parent"        android:layout_height="match_parent" /></RelativeLayout>

MainActivity：

public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);ListView mListView = (ListView) findViewById(R.id.listview);String[] textArray = {"功能1","功能2","功能3","功能4","功能5","功能6","功能7","功能8"};/* * 定义数据适配器 * android.R.layout.simple_list_item_1  Listview的子条目显示的布局的id * textArray 显示在ListView列表中的数据 */ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, textArray);mListView.setAdapter(adapter);}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.main, menu);return true;}}

②SimpleAdapter演示

在ListView的使用中，SimpleAdapter使用最多。

public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);ListView mListView = (ListView) findViewById(R.id.listview);List<Map<String, Object>> data = new ArrayList<Map<String,Object>>();Map<String, Object> map = new HashMap<String, Object>();map.put("name", "张三1");map.put("icon", R.drawable.f007);data.add(map);map = new HashMap<String, Object>();map.put("name", "张三2");map.put("icon", R.drawable.f007);data.add(map);map = new HashMap<String, Object>();map.put("name", "张三3");map.put("icon", R.drawable.f007);data.add(map);map = new HashMap<String, Object>();map.put("name", "张三4");map.put("icon", R.drawable.f007);data.add(map);map = new HashMap<String, Object>();map.put("name", "张三5");map.put("icon", R.drawable.f007);data.add(map);SimpleAdapter adapter = new SimpleAdapter(this, // 上下文data, // listView绑定的数据R.layout.listview_item, // listview的子条目的布局的idnew String[]{"name", "icon"}, // data数据中的map集合里的keynew int[]{R.id.tv_name, R.id.iv_icon}); // resource 中的idmListView.setAdapter(adapter);}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.main, menu);return true;}}
