Android開電話號碼

Question

我有這些代碼基本上用一個ListView顯示在聯繫人列表中的名字，我想，當單擊每個單獨的名稱，以獲得他們的電話號碼：

final ContentResolver cr = getContentResolver(); 

final Cursor c = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null); 
myCursorAdapter = new SimpleCursorAdapter(this, R.layout.list_item, c, new String[] {ContactsContract.Contacts.DISPLAY_NAME}, new int[]{R.id.TVRow}, 0); 
myPhoneList.setAdapter(myCursorAdapter); 

myPhoneList.setOnItemClickListener(new AdapterView.OnItemClickListener(){ 
    @Override 
    public void onItemClick(AdapterView<?> parent, View view, int position, long id){ 
     c.moveToPosition(position); 
     Toast.makeText(getApplicationContext(), c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)), Toast.LENGTH_SHORT).show(); 
    } 
}); 

在onItemClick方法

GetColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER) 

返回-1，因此我無法使用此方法獲取電話號碼。

我也嘗試打印出光標c的所有列，它返回34列，但似乎與電話號碼有關的唯一列是HasPhoneNumber。

那麼問題在哪裏，我該如何解決？謝謝！

更新後的版本，其中String陣列通過構建myCursorAdapter改變：

final ContentResolver cr = getContentResolver(); 

    final Cursor c = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null); 
    myCursorAdapter = new SimpleCursorAdapter(this, R.layout.list_item, c, new String[] {ContactsContract.CommonDataKinds.Phone.NUMBER}, new int[]{R.id.TVRow}, 0); 
    myPhoneList.setAdapter(myCursorAdapter); 

    myPhoneList.setOnItemClickListener(new AdapterView.OnItemClickListener(){ 
     @Override 
     public void onItemClick(AdapterView<?> parent, View view, int position, long id){ 
      c.moveToPosition(position); 
      Toast.makeText(getApplicationContext(), c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)), Toast.LENGTH_SHORT).show(); 
     } 
    }); 

我想更新的代碼會顯示在ListView的電話號碼，但我得到了一個錯誤說「欄目'data1'不存在「。

Answer 1

ContactsContract Android API在Data表中存儲有關聯繫人（如電話號碼）的數據，而不是Contacts表。

請仔細閱讀：https://developer.android.com/reference/android/provider/ContactsContract.html。

更新 - 這裏是你的代碼（未經測試）的一個固定的版本：

所有的

final ContentResolver cr = getContentResolver(); 
String[] projection = new String[] {Contacts.DISPLAY_NAME, Phone.NUMBER}; 
final Cursor c = cr.query(Data.CONTENT_URI, projection, null, null, null); 
myCursorAdapter = new SimpleCursorAdapter(this, R.layout.list_item, c, new String[] {Phone.NUMBER}, new int[]{R.id.TVRow}, 0); 
myPhoneList.setAdapter(myCursorAdapter); 

myPhoneList.setOnItemClickListener(new AdapterView.OnItemClickListener(){ 
    @Override 
    public void onItemClick(AdapterView<?> parent, View view, int position, long id){ 
     c.moveToPosition(position); 
     Toast.makeText(getApplicationContext(), c.getString(1), Toast.LENGTH_SHORT).show(); 
    } 
});

返回-1，因爲你不從DB請求列ContactsContract.CommonDataKinds.Phone.NUMBER：

new String[] {ContactsContract.Contacts.DISPLAY_NAME} 

ContactsContract.Contacts.DISPLAY_NAME是你要求的唯一領域。

爲了能夠得到的電話號碼，你首先需要把它列入到你想從DB獲得列的列表：

新的String [] {ContactsContract.Contacts.DISPLAY_NAME，ContactsContract.CommonDataKinds.Phone.NUMBER}

現在，您必須重寫適配器的getView，以便將名稱設置爲列表行的textView。之後，您的onItemClick將按預期工作

首先在AndroidManifest.xml中加入這一行採取許可的用戶。

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

實施

 phoneContactsButtton.setOnClickListener(new OnClickListener() { 
      @Override 
      public void onClick(View view) { 
      // The below two line is needed to open the contact list of mobile 
       Intent contactPickerIntent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); 
       startActivityForResult(contactPickerIntent,1); 

      } 
     }); 

你必須重寫onActivityResult（）將被寫入的onCreate外（）mehtod 與此類似

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    } 


@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 

    switch (requestCode){ 
     case 1 : 
      if (resultCode == Activity.RESULT_OK) { 
       Uri contactData = data.getData(); 

       Cursor cur = getContentResolver().query(contactData, null, null, null, null); 
       if (cur.getCount() > 0) {// thats mean some resutl has been found 
        if(cur.moveToNext()) { 
         String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID)); 
         String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 
         Log.e("Names", name); 

         if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) 
         { 

          Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ id,null, null); 
          while (phones.moveToNext()) { 
           String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
           Log.e("Number", phoneNumber); 
          } 
          phones.close(); 
         } 

        } 
       } 
       cur.close(); 
      } 
      break; 
    } 

}
