android獲取所有聯繫人

Question

如何獲取Android中聯繫人的所有名稱並將其放入字符串數組中？

Answer 1

試試這個太，

private void getContactList() { 
    ContentResolver cr = getContentResolver(); 
    Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, 
      null, null, null, null); 

    if ((cur != null ? cur.getCount() : 0) > 0) { 
     while (cur != null && cur.moveToNext()) { 
      String id = cur.getString(
        cur.getColumnIndex(ContactsContract.Contacts._ID)); 
      String name = cur.getString(cur.getColumnIndex(
        ContactsContract.Contacts.DISPLAY_NAME)); 

      if (cur.getInt(cur.getColumnIndex(
        ContactsContract.Contacts.HAS_PHONE_NUMBER)) > 0) { 
       Cursor pCur = cr.query(
         ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 
         null, 
         ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", 
         new String[]{id}, null); 
       while (pCur.moveToNext()) { 
        String phoneNo = pCur.getString(pCur.getColumnIndex(
          ContactsContract.CommonDataKinds.Phone.NUMBER)); 
        Log.i(TAG, "Name: " + name); 
        Log.i(TAG, "Phone Number: " + phoneNo); 
       } 
       pCur.close(); 
      } 
     } 
    } 
    if(cur!=null){ 
     cur.close(); 
    } 
} 

如果您需要更多的基準裝置是指該鏈接Read ContactList

Answer 2

Cursor contacts = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null); 
String aNameFromContacts[] = new String[contacts.getCount()]; 
String aNumberFromContacts[] = new String[contacts.getCount()]; 
int i = 0; 

int nameFieldColumnIndex = contacts.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME); 
int numberFieldColumnIndex = contacts.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER); 

while(contacts.moveToNext()) { 

    String contactName = contacts.getString(nameFieldColumnIndex); 
    aNameFromContacts[i] = contactName ; 

    String number = contacts.getString(numberFieldColumnIndex); 
    aNumberFromContacts[i] = number ; 
i++; 
} 

contacts.close(); 

其結果將是aNameFromContacts陣列充分接觸。另外，還要確保您已在main.xml中

public class MyActivity extends Activity 
         implements LoaderManager.LoaderCallbacks<Cursor> { 

    private static final int CONTACTS_LOADER_ID = 1; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     // Prepare the loader. Either re-connect with an existing one, 
     // or start a new one. 
     getLoaderManager().initLoader(CONTACTS_LOADER_ID, 
             null, 
             this); 
    } 

    @Override 
    public Loader<Cursor> onCreateLoader(int id, Bundle args) { 
     // This is called when a new Loader needs to be created. 

     if (id == CONTACTS_LOADER_ID) { 
      return contactsLoader(); 
     } 
     return null; 
    } 

    @Override 
    public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) { 
     //The framework will take care of closing the 
     // old cursor once we return. 
     List<String> contacts = contactsFromCursor(cursor); 
    } 

    @Override 
    public void onLoaderReset(Loader<Cursor> loader) { 
     // This is called when the last Cursor provided to onLoadFinished() 
     // above is about to be closed. We need to make sure we are no 
     // longer using it. 
    } 

    private Loader<Cursor> contactsLoader() { 
     Uri contactsUri = ContactsContract.Contacts.CONTENT_URI; // The content URI of the phone contacts 

     String[] projection = {         // The columns to return for each row 
       ContactsContract.Contacts.DISPLAY_NAME 
     } ; 

     String selection = null;         //Selection criteria 
     String[] selectionArgs = {};        //Selection criteria 
     String sortOrder = null;         //The sort order for the returned rows 

     return new CursorLoader(
       getApplicationContext(), 
       contactsUri, 
       projection, 
       selection, 
       selectionArgs, 
       sortOrder); 
    } 

    private List<String> contactsFromCursor(Cursor cursor) { 
     List<String> contacts = new ArrayList<String>(); 

     if (cursor.getCount() > 0) { 
      cursor.moveToFirst(); 

      do { 
       String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 
       contacts.add(name); 
      } while (cursor.moveToNext()); 
     } 

     return contacts; 
    } 

} 

添加

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

，不要忘記

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

得到公正的代碼行數的聯繫人列表

Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null); 
while (phones.moveToNext()) 
{ 
    String name=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); 
    String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
    Toast.makeText(getApplicationContext(),name, Toast.LENGTH_LONG).show(); 

} 
phones.close();

獲取聯繫人信息，照片聯繫人，照片uri並轉換爲類型

1）。樣品分類型號：

public class ContactModel { 
     public String id; 
     public String name; 
     public String mobileNumber; 
     public Bitmap photo; 
     public Uri photoURI; 
    } 

2）。獲取聯繫人並轉換爲模型

 public List<ContactModel> getContacts(Context ctx) { 
     List<ContactModel> list = new ArrayList<>(); 
     ContentResolver contentResolver = ctx.getContentResolver(); 
     Cursor cursor = contentResolver.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null); 
     if (cursor.getCount() > 0) { 
      while (cursor.moveToNext()) { 
       String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID)); 
       if (cursor.getInt(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)) > 0) { 
        Cursor cursorInfo = contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, 
          ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[]{id}, null); 
        InputStream inputStream = ContactsContract.Contacts.openContactPhotoInputStream(ctx.getContentResolver(), 
          ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, new Long(id))); 

        Uri person = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, new Long(id)); 
        Uri pURI = Uri.withAppendedPath(person, ContactsContract.Contacts.Photo.CONTENT_DIRECTORY); 

        Bitmap photo = null; 
        if (inputStream != null) { 
         photo = BitmapFactory.decodeStream(inputStream); 
        } 
        while (cursorInfo.moveToNext()) { 
         ContactModel info = new ContactModel(); 
         info.id = id; 
         info.name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 
         info.mobileNumber = cursorInfo.getString(cursorInfo.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
         info.photo = photo; 
         info.photoURI= pURI; 
         list.add(info); 
        } 

        cursorInfo.close(); 
       } 
      } 
      cursor.close(); 
     } 
     return list; 
    }
