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"/>
