Android例子—内容提供者操作手机联系人

简单的读取手机联系人

核心代码

private void getContacts(){
//①查询raw_contacts表获得联系人的id
ContentResolver resolver = getContentResolver();
Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
//查询联系人数据
cursor = resolver.query(uri, null, null, null, null);
while(cursor.moveToNext())
{
//获取联系人姓名,手机号码
String cName = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String cNum = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
System.out.println("姓名:" + cName);
System.out.println("号码:" + cNum);
System.out.println("======================");
}
cursor.close();
}

加读联系人的权限

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

查询指定电话的联系人信息

核心代码

private void queryContact(String number){
Uri uri = Uri.parse("content://com.android.contacts/data/phones/filter/" + number);
ContentResolver resolver = getContentResolver();
Cursor cursor = resolver.query(uri, new String[]{"display_name"}, null, null, null);
if (cursor.moveToFirst()) {
String name = cursor.getString(0);
System.out.println(number + "对应的联系人名称：" + name);
}
cursor.close();
}

添加一个新的联系人

核心代码

private void AddContact() throws RemoteException, OperationApplicationException {
//使用事务添加联系人
Uri uri = Uri.parse("content://com.android.contacts/raw_contacts");
Uri dataUri =  Uri.parse("content://com.android.contacts/data");

ContentResolver resolver = getContentResolver();
ArrayList<ContentProviderOperation> operations = new ArrayList<ContentProviderOperation>();
ContentProviderOperation op1 = ContentProviderOperation.newInsert(uri)
.withValue("account_name", null)
.build();
operations.add(op1);

//依次是姓名，号码，邮编
ContentProviderOperation op2 = ContentProviderOperation.newInsert(dataUri)
.withValueBackReference("raw_contact_id", 0)
.withValue("mimetype", "vnd.android.cursor.item/name")
.withValue("data2", "Coder-pig")
.build();
operations.add(op2);

ContentProviderOperation op3 = ContentProviderOperation.newInsert(dataUri)
.withValueBackReference("raw_contact_id", 0)
.withValue("mimetype", "vnd.android.cursor.item/phone_v2")
.withValue("data1", "13798988888")
.withValue("data2", "2")
.build();
operations.add(op3);

ContentProviderOperation op4 = ContentProviderOperation.newInsert(dataUri)
.withValueBackReference("raw_contact_id", 0)
.withValue("mimetype", "vnd.android.cursor.item/email_v2")
.withValue("data1", "779878443@qq.com")
.withValue("data2", "2")
.build();
operations.add(op4);
//将上述内容添加到手机联系人中~
resolver.applyBatch("com.android.contacts", operations);
Toast.makeText(getApplicationContext(), "添加成功", Toast.LENGTH_SHORT).show();
}

别忘了权限

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