Android(安卓)SimpleAdapter显示ListView、GridView

SimpleAdapter作为一个数据集，主要向ListView、GridView容器填充数据，总结了几种填充方式，原理很简单，直接看代码和效果图

1、 ListView单行显示（simple_list_item_1）

代码：

public class myListItem1 extends Activity{@Overridepublic void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);ListView listView = new ListView(this);List<Map<String, String>> mList = new ArrayList<Map<String, String>>();for(int i=0; i<10; i++){Map<String, String> map = new HashMap<String, String>();map.put("TITLE", "Test Title");map.put("CONTENT", "Test Content");mList.add(map);}SimpleAdapter adapter = new SimpleAdapter(this,mList,android.R.layout.simple_list_item_1,// List 显示一行item1new String[]{ "CONTENT" },// "TITLE", new int[]{ android.R.id.text1 });listView.setAdapter(adapter);setContentView(listView);}}

效果：

2、 ListView双行显示（simple_list_item_2）

代码：

public class myListItem2 extends Activity{@Overridepublic void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);ListView listView = new ListView(this);List<Map<String, String>> mList = new ArrayList<Map<String, String>>();for(int i=0; i<10; i++){Map<String, String> map = new HashMap<String, String>();map.put("TITLE", "Test Title");map.put("CONTENT", "Test Content");mList.add(map);}SimpleAdapter adapter = new SimpleAdapter(this,mList,android.R.layout.simple_list_item_2,// List 显示两行item1、item2new String[]{ "TITLE", "CONTENT" },new int[]{ android.R.id.text1, android.R.id.text2 });listView.setAdapter(adapter);setContentView(listView);}}

效果：

3、 ListView自定义显示

代码：

public class MyList extends Activity {@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.mylist);List<Map<String, Object>> mList = new ArrayList<Map<String, Object>>();for (int i = 0; i < 10; i++) {Map<String, Object> map = new HashMap<String, Object>();map.put("PIC", R.drawable.pic);// 加载图片资源map.put("TITLE", "Test Title");map.put("CONTENT", "Test Content");mList.add(map);}SimpleAdapter adapter = new SimpleAdapter(this,mList,R.layout.listitem,// 自定义布局格式new String[] { "PIC", "TITLE", "CONTENT" }, new int[] { R.id.listitem_pic, R.id.listitem_title, R.id.listitem_content });ListView listView = (ListView) findViewById(R.id.list);listView.setAdapter(adapter);}}

自定义的 listitem.xml

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"        android:layout_width="fill_parent"         android:layout_height="?android:attr/listPreferredItemHeight">                <ImageView android:id="@+id/listitem_pic"                android:layout_width="wrap_content"                 android:layout_height="fill_parent"                android:layout_alignParentTop="true"                 android:layout_alignParentBottom="true"                android:adjustViewBounds="true"                android:padding="10dip" />                <TextView android:id="@+id/listitem_title"                android:layout_width="wrap_content"                 android:layout_height="wrap_content"                android:layout_toRightOf="@id/listitem_pic"                android:layout_alignParentRight="true"                 android:layout_alignParentTop="true"                android:layout_alignWithParentIfMissing="true"                 android:gravity="center_vertical"                android:textSize="22sp" />                <TextView android:id="@+id/listitem_content"                android:layout_width="fill_parent"                 android:layout_height="wrap_content"                android:layout_toRightOf="@id/listitem_pic"                android:layout_alignParentBottom="true"                android:layout_alignParentRight="true"                 android:layout_below="@id/listitem_title"                android:singleLine="true"                android:ellipsize="marquee"                 android:textSize="14sp" /></RelativeLayout>

效果：

4、 GridView自定义显示

代码：

public class MyGrid extends Activity {@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.mygrid);List<Map<String, Object>> mList = new ArrayList<Map<String, Object>>();for (int i = 0; i < 10; i++) {Map<String, Object> map = new HashMap<String, Object>();map.put("PIC", R.drawable.pic);// 加载图片资源map.put("TITLE", "Test Title");mList.add(map);}SimpleAdapter adapter = new SimpleAdapter(this,mList, R.layout.griditem,// 自定义布局格式new String[] { "PIC", "TITLE" }, new int[] { R.id.griditem_pic, R.id.griditem_title, });GridView gridView = (GridView) findViewById(R.id.grid);gridView.setAdapter(adapter);}}

自定义的 gridview.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_height="fill_parent" android:layout_width="fill_parent"android:orientation="vertical"><ImageView android:id="@+id/griditem_pic"android:layout_width="wrap_content" android:layout_height="wrap_content"android:layout_gravity="center_horizontal"></ImageView><TextView android:id="@+id/griditem_title"android:layout_width="wrap_content" android:layout_height="wrap_content"android:layout_gravity="center_horizontal"></TextView></LinearLayout>

效果：
