在android中读取联系人信息的程序，包括读取联系人姓名、手机号码和邮箱
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>
里面重要的是搭建测试环境和添加<uses-permission>，即读取和写入联系人信息的权限
2：读取的主要方法
/* * 读取联系人的信息 */ public void testReadAllContacts() { Cursor cursor = this.getContext().getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null); int contactIdIndex = 0; int nameIndex = 0; if(cursor.getCount() > 0) { contactIdIndex = cursor.getColumnIndex(ContactsContract.Contacts._ID); nameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME); } while(cursor.moveToNext()) { String contactId = cursor.getString(contactIdIndex); String name = cursor.getString(nameIndex); Log.i(TAG, contactId); Log.i(TAG, name); /* * 查找该联系人的phone信息 */ Cursor phones = this.getContext().getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + contactId, null, null); int phoneIndex = 0; if(phones.getCount() > 0) { phoneIndex = phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER); } while(phones.moveToNext()) { String phoneNumber = phones.getString(phoneIndex); Log.i(TAG, phoneNumber); } /* * 查找该联系人的email信息 */ Cursor emails = this.getContext().getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, ContactsContract.CommonDataKinds.Email.CONTACT_ID + "=" + contactId, null, null); int emailIndex = 0; if(emails.getCount() > 0) { emailIndex = emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA); } while(emails.moveToNext()) { String email = emails.getString(emailIndex); Log.i(TAG, email); } } }
3：目前手机中的联系人信息，有两个联系人的信息，如图所示，
这是Hellen的联系信息
这是Mike的联系信息
4：测试结果，在控制台输出的内容为：
可以看到在控制台输出了两个联系人的信息。
//--------------------------------------
获取所有分组编号和组的名称
Cursor groupInfoCursor = getContentResolver().query(ContactsContract.Groups.CONTENT_URI, null, null, null, null);
while(groupInfoCursor.moveToNext()) {
int idIndex = groupInfoCursor.getColumnIndex(ContactsContract.Groups._ID);
int titleIndex = groupInfoCursor.getColumnIndex(ContactsContract.Groups.TITLE);
String id = groupInfoCursor.getString(idIndex);
String title = groupInfoCursor.getString(titleIndex);
}
groupInfoCursor.close();

先加二个读和写权限：
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
package com.eboy.test;

public class ContectTest extends AndroidTestCase {
private static final String TAG = "TestContact";
//查询所有联系人的姓名，电话，邮箱
public void TestContact() throws Exception {
Uri uri = Uri.parse("content://com.android.contacts/contacts");
ContentResolver resolver = getContext().getContentResolver();
Cursor cursor = resolver.query(uri, new String[]{"_id"}, null, null, null);
while (cursor.moveToNext()) {
int contractID = cursor.getInt(0);
StringBuilder sb = new StringBuilder("contractID=");
sb.append(contractID);
uri = Uri.parse("content://com.android.contacts/contacts/" + contractID + "/data");
Cursor cursor1 = resolver.query(uri, new String[]{"mimetype", "data1", "data2"}, null, null, null);
while (cursor1.moveToNext()) {
String data1 = cursor1.getString(cursor1.getColumnIndex("data1"));
String mimeType = cursor1.getString(cursor1.getColumnIndex("mimetype"));
if ("vnd.android.cursor.item/name".equals(mimeType)) { //是姓名

} else if ("vnd.android.cursor.item/phone_v2".equals(mimeType)) { //手机
sb.append(",phone=" + data1);
}
}
cursor1.close();
Log.i(TAG, sb.toString());
}
cursor.close();
}
//查询指定电话的联系人姓名，邮箱
public void testContactNameByNumber() throws Exception {

}
//添加联系人，使用事务
