Question

是Android（Java）的新手，我想执行一项简单的任务我如何获取设备上的所有联系人电话号码，电子邮件和全名以及他们的详细信息并放入它们就像一个阵列一样我来自PHP背景，所以这个阵列会在PHP中看起来像这样：

 ContactsArray[0] = array(
                    'fullname' => 'John doe',
                    'Phone' => '0909809890' ,
                    'email' => 'johndoe@email.com'
                         )

从PHP的角度来看，数组应该是什么样的，我是Android新手，想要一个类来获取所有这些数据把它们放在一个数组中返回数据。

PSEUDO CODE

     function GetContacts(){
     contacts = fetchAllContactsDetails
     return contacts;
     }

Answer 1

这可能是一个开始。请注意，我没有对此进行测试，可能会出现错误，但您会明白这一点。

阅读本文以获取有关多维数组的更多信息。 Link

String phpArray;
int x=3;
int y=array.length();
String[][] myStringArray = new String [y][x];

for(int i=0; i<array.length; i++){
    for(int j=0; j<3; j++){
        phpArray = contactsArray[i];
        myStringARray[i][j] = phpArray[j];
    }

}

首先，您需要添加读取清单文件中联系人的权限：

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

您可以查看此代码：

public void fetchContacts() { 
    String phoneNumber = null; 
    String email = null; 
    Uri CONTENT_URI = ContactsContract.Contacts.CONTENT_URI; 
    String _ID = ContactsContract.Contacts._ID; 
    String DISPLAY_NAME = ContactsContract.Contacts.DISPLAY_NAME; 
    String HAS_PHONE_NUMBER = ContactsContract.Contacts.HAS_PHONE_NUMBER; 
    Uri PhoneCONTENT_URI = ContactsContract.CommonDataKinds.Phone.CONTENT_URI; 
    String Phone_CONTACT_ID = ContactsContract.CommonDataKinds.Phone.CONTACT_ID; 
    String NUMBER = ContactsContract.CommonDataKinds.Phone.NUMBER; 
    Uri EmailCONTENT_URI =  ContactsContract.CommonDataKinds.Email.CONTENT_URI;
    String EmailCONTACT_ID = ContactsContract.CommonDataKinds.Email.CONTACT_ID; 
    String DATA = ContactsContract.CommonDataKinds.Email.DATA; 
    StringBuffer output = new StringBuffer(); 
    ContentResolver contentResolver = getContentResolver(); 
    Cursor cursor = contentResolver.query(CONTENT_URI, null,null, null, null);   
    // Loop for every contact in the phone 
    if (cursor.getCount() > 0) { 
        while (cursor.moveToNext()) { 
            String contact_id = cursor.getString(cursor.getColumnIndex( _ID )); 
            String name = cursor.getString(cursor.getColumnIndex( DISPLAY_NAME )); 
            int hasPhoneNumber = Integer.parseInt(cursor.getString(cursor.getColumnIndex( HAS_PHONE_NUMBER ))); 
            if (hasPhoneNumber > 0) { 
                output.append("\n First Name:" + name); 
                // Query and loop for every phone number of the contact 
                Cursor phoneCursor = contentResolver.query(PhoneCONTENT_URI, null, Phone_CONTACT_ID + " = ?", new String[] { contact_id }, null); 
                while (phoneCursor.moveToNext()) { 
                    phoneNumber = phoneCursor.getString(phoneCursor.getColumnIndex(NUMBER)); 
                    output.append("\n Phone number:" + phoneNumber); 

                } 
                phoneCursor.close(); 
                // Query and loop for every email of the contact 
                Cursor emailCursor = contentResolver.query(EmailCONTENT_URI,    null, EmailCONTACT_ID+ " = ?", new String[] { contact_id }, null); 

                while (emailCursor.moveToNext()) { 

                    email = emailCursor.getString(emailCursor.getColumnIndex(DATA)); 
                    output.append("\nEmail:" + email); 

                } 

                emailCursor.close(); 
            } 
            output.append("\n"); 

        } 
        outputText.setText(output); 
    } 
}

}
