Google联系人问题示例“选择特定联系人数据”

问题描述：

我使用的是谷歌示例https://developer.android.com/guide/components/intents-common.html 可正常工作以使用以下代码启动联系人浏览器。Google联系人问题示例“选择特定联系人数据”

Intent intent = new Intent(Intent.ACTION_PICK); 
    intent.setType(ContactsContract.Contacts.CONTENT_TYPE); 
    if (intent.resolveActivity(getPackageManager()) != null) { 
     startActivityForResult(intent, PHONE_ACTIVITY); 
    }

我选择一个联系人和活动退出，并调用我的onActivityResult（）

然而，当我使用示例代码从它抛出的意图和非法柱异常数据1的结果，当它到达查询的最后一行（）

public void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 
     switch (requestCode) { 
     case (PHONE_ACTIVITY): { 
      if (resultCode == Activity.RESULT_OK) { 
       Uri contactUri = data.getData(); 
       String[] projection = new String[]{CommonDataKinds.Phone.NUMBER}; 
       Cursor cursor = getContentResolver().query(contactUri, projection, 
         null, null, null); 
      }}}}

我不知道什么是错的。数据在Uri中，但是我得到了下面的堆栈转储。

好的，如果有人感兴趣的底线是谷歌的例子有一个错误。一般的方法是正确的，你打电话给联系人的代码，但这再次分解到联系人界面有点复杂和记录不完善。我将投影设置为null，并将数据解析为这样。

  ContentResolver contentResolver = getContentResolver(); 
      Cursor cursor = getContentResolver().query(contactUri, 
        null, null, null, null); 
      // If the cursor returned is valid, get the phone number 
      if (cursor != null && cursor.getCount() > 0) { 
       cursor.moveToFirst(); 
       String contact_id = cursor.getString(cursor 
         .getColumnIndex(ContactsContract.Contacts._ID)); 
       int numberIndex = cursor 
         .getColumnIndex(CommonDataKinds.Phone.NUMBER); 
       int hasPhoneNumber = Integer 
         .parseInt(cursor.getString(cursor 
           .getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))); 

       if (hasPhoneNumber > 0) { 
        Cursor phoneCursor = contentResolver 
          .query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 
            null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", 
            new String[] { contact_id }, null); 
        boolean found = false; 
        while (phoneCursor.moveToNext()) { 
         String phoneNumber = phoneCursor 
           .getString(phoneCursor 
             .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
         int phoneType = phoneCursor.getInt(phoneCursor 
           .getColumnIndex(Phone.TYPE)); 
         if (phoneType == Phone.TYPE_MOBILE) { 
          phoneNumber = phoneNumber.replaceAll(
            "[^\\d]", ""); 
          if (phoneNumber.startsWith("1")) { 
           phoneNumber = phoneNumber.substring(1, 
             phoneNumber.length()); 
          }}}}
