android 4组件之 provider--访问通讯录

a
provider是一个组件需要在清单中配置，和activity是并列的关系。
android:authorities是内容提供者的唯一标示，其他应用根据这个找到这个内容提供者。

<provider android:name=".PersonContentProvider" android:authorities="cn.itcast.provides.personprovider"/>

b.
访问联系人的provider

调用

ContactTest contact =new ContactTest(this);        ArrayList<HashMap<String, Object>> persons = null ;                try {                persons = contact.GetContacts();for(int i=0;i<persons.size();i++){        HashMap<String, Object> map = new HashMap<String, Object>();        map.put("ItemImage", R.drawable.ic_launcher);//图像资源的ID        map.put("ItemTitle",(String) persons.get(i).get("name"));        map.put("ItemText", (String) persons.get(i).get("phone"));        mArrayList.add(map);}} catch (Throwable e) {// TODO Auto-generated catch blocke.printStackTrace();}

配置权限

<uses-permission android:name="android.permission.READ_CONTACTS" /><uses-permission android:name="android.permission.WRITE_CONTACTS" />
