使用Intent.ACTION_PICK

Question

閱讀電話號碼以及地址我想從建立聯繫人選擇器中讀取聯繫信息。我正在閱讀電話號碼，街道，電子郵件和地址。它出錯了。

以下是代碼調用聯繫人挑選：

Intent contactPickerIntent = new Intent(Intent.ACTION_PICK, ContactsContract.CommonDataKinds.Phone.CONTENT_URI); 
context.startActivityForResult(contactPickerIntent, REQUEST_ID_CONTACT_PICKER); 

以下是OnActivityResult方法的代碼，在那裏我是從光標fetching contact信息：

Uri contactURI = intent.getData(); 
        Cursor cursor = activity.getContentResolver().query(contactURI, null, null, null, null); 
int count = cursor.getCount(); 
// here value of count is 1, so need to do cursor.moveToNext() to go to selected record. 
if (cursor.moveToNext()) { 
      String givenName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 
      String familyName = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.FAMILY_NAME)); 
      String displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME)); 
      String middleName = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.MIDDLE_NAME)); 

      int contactType = cursor.getInt(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE)); 
      String phoneNo = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
      String poBox = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POBOX)); 
      String street = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.STREET)); 
      String city = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.CITY)); 
      String state = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.REGION)); 
      String postalCode = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POSTCODE)); 
      String country = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.COUNTRY)); 
      String neighborhood = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.NEIGHBORHOOD)); 
      String formattedAddress = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.FORMATTED_ADDRESS)); 
      String emailId = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA)); 

     } 

我無法確定，爲什麼我在街道，emailId等欄目中收到錯誤的數據（即聯繫電話號碼）。

這裏cursor.moveToNext（）必須去第一排，所以它的 明顯必需的，我的問題不是我得到不同的 記錄，我得到在街上的手機號碼，EMAILID列，這是錯誤的 。

浪費後超過3天發現做我想要的方式：

有用於存儲所有類型的數據，即電話，地址，電子郵件等的是一個common structure See the common columns names，

這就是爲什麼我們無法獲得所有類型的數據（聯繫人，電子郵件，地址 等）與接觸選擇器的意圖，所以首先我們需要聯繫 ID或聯繫lookUpKey作爲結果的聯繫人選擇器的意圖，比我們 需要單獨查詢其他細節。

但嘗試獲取其他詳細信息時會出現問題，因爲每個 數據都保存在相同的表結構中，即可以使用 保存任何類型的聯繫人數據的通用表。

並且存儲在給定行中的數據的類型由行的 MIMETYPE值指定，該值確定了通用列 DATA1到DATA15的含義。例如，如果數據Mime類型爲 Phone.CONTENT_ITEM_TYPE，則DATA1列存儲電話號碼 ，但如果數據Mime類型爲Email.CONTENT_ITEM_TYPE，則 DATA1存儲電子郵件地址。

所以首先我們需要查詢 的任何類型的內容之前設置好MIME類型條款，請參閱MIME類型的列表here

這是我們應該如何火的意圖來選擇聯繫人：

int REQUEST_ID_CONTACT_PICKER = 1001; 
Intent contactPickerIntent = new Intent(Intent.ACTION_PICK, ContactsContract.CommonDataKinds.Phone.CONTENT_URI); 
startActivityForResult(contactPickerIntent, REQUEST_ID_CONTACT_PICKER); 

比onActivityResult，我們得到的URI數據：

public void onActivityResult(int requestCode, int resultCode, Intent intent) { 
    Contact contact = null; 
    if (resultCode == Activity.RESULT_OK) { 
     switch (requestCode) { 
     case REQUEST_ID_CONTACT_PICKER : 
      try { 
      Uri contactURI = intent.getData(); 
      contact = fetchAndBuildContact(getApplicationContext(), contactURI); 
      Log.d(LOG_TAG, "Pick contact sucessfully!!"+contact.toString()); 
      } 
      catch (Exception e) { 
      Log.e(LOG_TAG, "Failed to pick contact!!"); 
      e.printStackTrace(); 
      } 
      break; 
     } 
    } else { 
     Log.e(LOG_TAG, "Failed to pick contact!!"); 
    } 
    } 

不是我們需要找到LookUpKey，有利於獲取任何MIME類型的數據：

private Contact fetchAndBuildContact(Context ctx, Uri uriContact){ 
     // Getting cursorLookUpKey because contacts ID may not be correct all the time. 
     Cursor cursorLookUpKey = ctx.getContentResolver().query(uriContact, new String[]{ContactsContract.Data.LOOKUP_KEY}, null, null, null); 
     Contact contact = null; 
     String lookupKey = null; 
     if (cursorLookUpKey.moveToFirst()) { 
      lookupKey = cursorLookUpKey.getString(cursorLookUpKey.getColumnIndex(ContactsContract.Data.LOOKUP_KEY)); 
      if(null != lookupKey){ 
       contact = new Contact(); 
       contact = buildConactPhoneDetails(lookupKey, ctx, contact); 
       contact = buildEmailDetails(lookupKey, ctx, contact); 
       contact = buildAddressDetails(lookupKey, ctx, contact); 
      } 
     } 
     cursorLookUpKey.close(); 
     return contact; 
    } 

這就是我們如何能夠利用ContactsContract.Data.MIMETYPE = ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE獲取手機詳情：

private Contact buildConactPhoneDetails(String lookupKey, Context ctx, final Contact contact) { 
     ContentResolver contentResolver = ctx.getContentResolver(); 
     String contactWhere = ContactsContract.Data.LOOKUP_KEY + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?"; 
     String[] contactWhereParams = new String[]{lookupKey, ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE}; 
     Cursor cursorPhone = contentResolver.query(ContactsContract.Data.CONTENT_URI, null, contactWhere, contactWhereParams, null); 
     if (cursorPhone.getCount() > 0) { 
      if (cursorPhone.moveToNext()) { 
       if (Integer.parseInt(cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) { 
        String givenName = cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 
        String familyName = cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.FAMILY_NAME)); 
        String middleName = cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.MIDDLE_NAME)); 
        int contactType = cursorPhone.getInt(cursorPhone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE)); 
        String phoneNo = cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
        contact.contactNumber = phoneNo; 
        contact.givenName = givenName; 
        contact.familyName = familyName; 
        contact.middleName = middleName; 
        contact.contactType = contactType; 
       } 
      } 
     } 
     cursorPhone.close(); 
     return contact; 
    } 

這是我們如何可以使用ContactsContract.Data.MIMETYPE = ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE獲取電子郵件詳細信息：

private Contact buildEmailDetails (String lookupKey, Context ctx, final Contact contact) { 
     ContentResolver contentResolver = ctx.getContentResolver(); 
     String emailWhere = ContactsContract.Data.LOOKUP_KEY+ " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?"; 
     String[] emailWhereParams = new String[]{lookupKey, ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE}; 
     Cursor emailCursor = contentResolver.query(ContactsContract.Data.CONTENT_URI, null, emailWhere, emailWhereParams, null); 
     if (emailCursor.moveToNext()) { 
      String emailId = emailCursor.getString(emailCursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA)); 
      contact.emailId = emailId; 
     } 
     emailCursor.close(); 
     return contact; 
    } 

這就是我們如何能夠利用ContactsContract.Data.MIMETYPE = ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_ITEM_TYPE獲取PhoneDetails：

private Contact buildAddressDetails(String lookupKey, Context ctx, final Contact contact) { 
    ContentResolver contentResolver = ctx.getContentResolver(); 
    String addrWhere = ContactsContract.Data.LOOKUP_KEY + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?"; 
    String[] addrWhereParams = new String[]{lookupKey, ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_ITEM_TYPE}; 
    Cursor addrCursor = contentResolver.query(ContactsContract.Data.CONTENT_URI, null, addrWhere, addrWhereParams, null); 
    if (addrCursor.moveToNext()) { 
     String poBox = addrCursor.getString(addrCursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POBOX)); 
     String street = addrCursor.getString(addrCursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.STREET)); 
     String city = addrCursor.getString(addrCursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.CITY)); 
     String state = addrCursor.getString(addrCursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.REGION)); 
     String postalCode = addrCursor.getString(addrCursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POSTCODE)); 
     String country = addrCursor.getString(addrCursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.COUNTRY)); 
     String neighborhood = addrCursor.getString(addrCursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.NEIGHBORHOOD)); 
     String formattedAddress = addrCursor.getString(addrCursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.FORMATTED_ADDRESS)); 

     contact.poBox = poBox; 
     contact.street = street; 
     contact.city = city; 
     contact.state = state; 
     contact.zipcode = postalCode; 
     contact.country = country; 
     contact.street = street; 
     contact.neighborhood = neighborhood; 
     contact.poBox = poBox; 
     contact.formattedAddress = formattedAddress; 
    } 
    addrCursor.close(); 
    return contact; 
    } 

，這是聯繫POJO類，我們在上面的代碼中創建：

public class Contact { 
    String country; 
    String poBox; 
    String givenName; 
    String middleName; 
    String familyName; 
    String address; 
    String city; 
    String state; 
    String street; 
    String zipcode; 
    String emailId; 
    String contactNumber; 
    String neighborhood; 
    String formattedAddress; 
    String label; 
    int contactType; 
}
