本文实例讲述了Android编程实现通讯录中联系人的读取,查询,添加功能。分享给大家供大家参考，具体如下：
先加二个读和写权限：
<uses-permission android:name="android.permission.READ_CONTACTS" /> <uses-permission android:name="android.permission.WRITE_CONTACTS" />
具体代码：
package com.eboy.test; import java.util.ArrayList; import android.content.ContentProviderOperation; import android.content.ContentResolver; import android.database.Cursor; import android.net.Uri; import android.test.AndroidTestCase; import android.util.Log; 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 sb.append(",name=" + data1); } else if ("vnd.android.cursor.item/email_v2".equals(mimeType)) { //邮箱 sb.append(",email=" + data1); } 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 { String number = "18052369652"; Uri uri = Uri.parse("content://com.android.contacts/data/phones/filter/" + number); ContentResolver resolver = getContext().getContentResolver(); Cursor cursor = resolver.query(uri, new String[]{"display_name"}, null, null, null); if (cursor.moveToFirst()) { String name = cursor.getString(0); Log.i(TAG, name); } cursor.close(); } //添加联系人，使用事务 public void testAddContact() throws Exception { Uri uri = Uri.parse("content://com.android.contacts/raw_contacts"); ContentResolver resolver = getContext().getContentResolver(); ArrayList<ContentProviderOperation> operations = new ArrayList<ContentProviderOperation>(); ContentProviderOperation op1 = ContentProviderOperation.newInsert(uri) .withValue("account_name", null) .build(); operations.add(op1); uri = Uri.parse("content://com.android.contacts/data"); ContentProviderOperation op2 = ContentProviderOperation.newInsert(uri) .withValueBackReference("raw_contact_id", 0) .withValue("mimetype", "vnd.android.cursor.item/name") .withValue("data2", "龚小永") .build(); operations.add(op2); ContentProviderOperation op3 = ContentProviderOperation.newInsert(uri) .withValueBackReference("raw_contact_id", 0) .withValue("mimetype", "vnd.android.cursor.item/phone_v2") .withValue("data1", "13539777967") .withValue("data2", "2") .build(); operations.add(op3); ContentProviderOperation op4 = ContentProviderOperation.newInsert(uri) .withValueBackReference("raw_contact_id", 0) .withValue("mimetype", "vnd.android.cursor.item/email_v2") .withValue("data1", "asdfasfad@163.com") .withValue("data2", "2") .build(); operations.add(op4); resolver.applyBatch("com.android.contacts", operations); } }
