android写入联系人Contacts的信息，包括联系人的姓名，联系方式和邮箱

1：androidmanifest.xml的内容

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="cn.itcast.contacts"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<uses-library android:name="android.test.runner" />
<activity android:name=".MainActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
<instrumentation android:name="android.test.InstrumentationTestRunner"
android:targetPackage="cn.itcast.contacts" android:label="Tests for My App" />
</manifest> 

2：ContactTest类，主要提供insert的插入方法

package cn.itcast.contacts.test;
import android.content.ContentUris;
import android.content.ContentValues;
import android.net.Uri;
import android.provider.ContactsContract.Data;
import android.provider.ContactsContract.RawContacts;
import android.provider.ContactsContract.CommonDataKinds.Email;
import android.provider.ContactsContract.CommonDataKinds.Phone;
import android.provider.ContactsContract.CommonDataKinds.StructuredName;
import android.test.AndroidTestCase;
public class ContactTest extends AndroidTestCase {
/*
* 首先向RawContacts.CONTENT_URI执行一个空值插入，目的是获得系统返回的rawContactId
* 这时后面插入data表的数据，只有执行空值插入，才能使插入的联系人在通讯录里面可见
*/
public void testInsert() {
ContentValues values = new ContentValues();
/*
* 首先向RawContacts.CONTENT_URI执行一个空值插入，目的是获得系统返回的rawContactId
*/
Uri rawContactUri = this.getContext().getContentResolver().insert(RawContacts.CONTENT_URI, values);
long rawContactId = ContentUris.parseId(rawContactUri);
//往data表里写入姓名数据
values.clear();
values.put(Data.RAW_CONTACT_ID, rawContactId);
values.put(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE); //内容类型
values.put(StructuredName.GIVEN_NAME, "李天山");
this.getContext().getContentResolver().insert(android.provider.ContactsContract.Data.CONTENT_URI, values);
//往data表里写入电话数据
values.clear();
values.put(Data.RAW_CONTACT_ID, rawContactId);
values.put(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE);
values.put(Phone.NUMBER, "13921009789");
values.put(Phone.TYPE, Phone.TYPE_MOBILE);
this.getContext().getContentResolver().insert(android.provider.ContactsContract.Data.CONTENT_URI, values);
//往data表里写入Email的数据
values.clear();
values.put(Data.RAW_CONTACT_ID, rawContactId);
values.put(Data.MIMETYPE, Email.CONTENT_ITEM_TYPE);
values.put(Email.DATA, "liming@itcast.cn");
values.put(Email.TYPE, Email.TYPE_WORK);
this.getContext().getContentResolver().insert(android.provider.ContactsContract.Data.CONTENT_URI, values);
}
}

3：测试结果，表明插入联系人成功

4：另外一种方式来添加联系人的信息

/*
* 批量添加，处于用一个事务中
*/
public void testSave() {
ArrayList<ContentProviderOperation> ops =new ArrayList<ContentProviderOperation>();
int rawContactInsertIndex = ops.size();
ops.add(ContentProviderOperation.newInsert(RawContacts.CONTENT_URI)
.withValue(RawContacts.ACCOUNT_TYPE, null)
.withValue(RawContacts.ACCOUNT_NAME, null)
.build());
ops.add(ContentProviderOperation.newInsert(Data.CONTENT_URI)
.withValueBackReference(Data.RAW_CONTACT_ID, rawContactInsertIndex)
.withValue(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE)
.withValue(StructuredName.DISPLAY_NAME, "良辰")
.build());
ops.add(ContentProviderOperation.newInsert(Data.CONTENT_URI)
.withValueBackReference(Data.RAW_CONTACT_ID, rawContactInsertIndex)
.withValue(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE)
.withValue(Phone.NUMBER, "1234567890")
.withValue(Phone.TYPE, Phone.TYPE_MOBILE)
.withValue(Phone.LABEL, "手机号")
.build());
ops.add(ContentProviderOperation.newInsert(Data.CONTENT_URI)
.withValueBackReference(Data.RAW_CONTACT_ID, rawContactInsertIndex)
.withValue(Data.MIMETYPE, Email.CONTENT_ITEM_TYPE)
.withValue(Email.DATA, "liangchen@itcast.cn")
.withValue(Email.TYPE, Email.TYPE_WORK)
.build());
ContentProviderResult[] results;
try {
results = this.getContext().getContentResolver()
.applyBatch(ContactsContract.AUTHORITY, ops);
for(ContentProviderResult result : results) {
Log.i(TAG, result.uri.toString());
}
} catch (RemoteException e) {
e.printStackTrace();
} catch (OperationApplicationException e) {
e.printStackTrace();
}
}

这种方法的好处用文档的英文表述就是：
The batch method is by far preferred. It inserts the raw contact and its constituent data rows in a single database transaction and causes at most one aggregation pass.
