Android 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{
@Override
public 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item1
new 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{
@Override
public 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、item2
new 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 {
@Override
public 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 {
@Override
public 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：
