Android SimpleAdapter顯示ListView、GridView

SimpleAdapter作為一個資料集，主要向ListView、GridView容器填充資料，總結了幾種填充方式，原理很簡單，直接看代碼和

1、 ListView單行顯示（simple_list_item_1）

代碼：

public class myListItem1 extends Activity{<br />@Override<br />public void onCreate(Bundle savedInstanceState){<br />super.onCreate(savedInstanceState);</p><p>ListView listView = new ListView(this);</p><p>List<Map<String, String>> mList = new ArrayList<Map<String, String>>();<br />for(int i=0; i<10; i++){<br />Map<String, String> map = new HashMap<String, String>();<br />map.put("TITLE", "Test Title");<br />map.put("CONTENT", "Test Content");<br />mList.add(map);<br />}</p><p>SimpleAdapter adapter = new SimpleAdapter(this,<br />mList,<br />android.R.layout.simple_list_item_1,// List 顯示一行item1<br />new String[]{ "CONTENT" },// "TITLE",<br />new int[]{ android.R.id.text1 }<br />);</p><p>listView.setAdapter(adapter);<br />setContentView(listView);<br />}<br />}

效果：

2、 ListView雙行顯示（simple_list_item_2）

代碼：

public class myListItem2 extends Activity{<br />@Override<br />public void onCreate(Bundle savedInstanceState){<br />super.onCreate(savedInstanceState);</p><p>ListView listView = new ListView(this);</p><p>List<Map<String, String>> mList = new ArrayList<Map<String, String>>();<br />for(int i=0; i<10; i++){<br />Map<String, String> map = new HashMap<String, String>();<br />map.put("TITLE", "Test Title");<br />map.put("CONTENT", "Test Content");<br />mList.add(map);<br />}</p><p>SimpleAdapter adapter = new SimpleAdapter(this,<br />mList,<br />android.R.layout.simple_list_item_2,// List 顯示兩行item1、item2<br />new String[]{ "TITLE", "CONTENT" },<br />new int[]{ android.R.id.text1, android.R.id.text2 }<br />);</p><p>listView.setAdapter(adapter);<br />setContentView(listView);<br />}<br />}

效果：

3、 ListView自訂顯示

代碼：

public class MyList extends Activity {<br />@Override<br />public void onCreate(Bundle savedInstanceState) {<br />super.onCreate(savedInstanceState);<br />setContentView(R.layout.mylist);</p><p>List<Map<String, Object>> mList = new ArrayList<Map<String, Object>>();<br />for (int i = 0; i < 10; i++) {<br />Map<String, Object> map = new HashMap<String, Object>();<br />map.put("PIC", R.drawable.pic);// 載入圖片資源<br />map.put("TITLE", "Test Title");<br />map.put("CONTENT", "Test Content");<br />mList.add(map);<br />}</p><p>SimpleAdapter adapter = new SimpleAdapter(this,<br />mList,<br />R.layout.listitem,// 自訂布局格式<br />new String[] { "PIC", "TITLE", "CONTENT" },<br />new int[] { R.id.listitem_pic, R.id.listitem_title, R.id.listitem_content }<br />);</p><p>ListView listView = (ListView) findViewById(R.id.list);<br />listView.setAdapter(adapter);<br />}<br />}自訂的 listitem.xml

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

效果：

4、 GridView自訂顯示

代碼：

public class MyGrid extends Activity {<br />@Override<br />public void onCreate(Bundle savedInstanceState) {<br />super.onCreate(savedInstanceState);<br />setContentView(R.layout.mygrid);</p><p>List<Map<String, Object>> mList = new ArrayList<Map<String, Object>>();<br />for (int i = 0; i < 10; i++) {<br />Map<String, Object> map = new HashMap<String, Object>();<br />map.put("PIC", R.drawable.pic);// 載入圖片資源<br />map.put("TITLE", "Test Title");<br />mList.add(map);<br />}<br />SimpleAdapter adapter = new SimpleAdapter(this,<br />mList, R.layout.griditem,// 自訂布局格式<br />new String[] { "PIC", "TITLE" },<br />new int[] { R.id.griditem_pic, R.id.griditem_title, }<br />);</p><p>GridView gridView = (GridView) findViewById(R.id.grid);<br />gridView.setAdapter(adapter);<br />}<br />}自訂的 gridview.xml
<?xml version="1.0" encoding="utf-8"?><br /><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"<br />android:layout_height="fill_parent"<br />android:layout_width="fill_parent"<br />android:orientation="vertical"></p><p><ImageView android:id="@+id/griditem_pic"<br />android:layout_width="wrap_content"<br />android:layout_height="wrap_content"<br />android:layout_gravity="center_horizontal"><br /></ImageView></p><p><TextView android:id="@+id/griditem_title"<br />android:layout_width="wrap_content"<br />android:layout_height="wrap_content"<br />android:layout_gravity="center_horizontal"><br /></TextView><br /></LinearLayout>
