Android ApiDemos示例解析(120):Views->Gallery->2. People

SimpleCursorAdapter 的构造函数如下

public SimpleCursorAdapter(Context context, int layout, Cursor c, String[] from, int[] to)

context: context对象，可以使用activity。
layout: layout 资源ID simple_gallery_item.xml
cursor： cursor对象，本例为通讯录cursor.
from: 需要显示的列名数组
to: 列对应的View 的id
[java] 
SpinnerAdapter adapter = new SimpleCursorAdapter(this, 
// Use a template that displays a text view  
 android.R.layout.simple_gallery_item, 
 // Give the cursor to the list adatper  
 c, 
 // Map the NAME column in the people database to...  
 new String[] {People.NAME}, 
 // The "text1" view defined in the XML template  
 new int[] { android.R.id.text1 }); 
 
Gallery g = (Gallery) findViewById(R.id.gallery); 
g.setAdapter(adapter); 

SpinnerAdapter adapter = new SimpleCursorAdapter(this,
// Use a template that displays a text view
 android.R.layout.simple_gallery_item,
 // Give the cursor to the list adatper
 c,
 // Map the NAME column in the people database to...
 new String[] {People.NAME},
 // The "text1" view defined in the XML template
 new int[] { android.R.id.text1 });

Gallery g = (Gallery) findViewById(R.id.gallery);
g.setAdapter(adapter);

本例Adapter 使用的View为TextView (id 为 android.R.id.text1） ，因此 Gallery显示的为联系人的人名。
