Question

我怎樣才能獲取在Android手機上的所有聯繫人，在一個活動？

Answer 1

1. 做出Contact類
2. 從ContentResolver()
3. 解析聯繫人列表中得到所有聯繫人列表，並填寫到ArrayList<Contact>
4. 使ContactArrayAdapter

ContactArrayAdapter樣品

//////////////////////////////////////////////////////////////////////////// 
private class ContactsAdapter extends ArrayAdapter<Contact> { 

    private final int _resourceId; 
    private final LayoutInflater _inflater; 
    private final Context _context; 

    public ContactsAdapter(Context context, int textViewResourceId, List<Contact> contacts) { 
     super(context, textViewResourceId, contacts); 
     _context = context; 
     _resourceId = textViewResourceId; 
     _inflater = LayoutInflater.from(context); 
    } 

    @Override 
    public View getView(int position, View v, ViewGroup parent) { 
     ViewHolder holder; 
     if (v == null) { 
      v = _inflater.inflate(_resourceId, null); 
      holder = new ViewHolder(); 
      holder.tv_name = (TextView) v.findViewById(R.id.tv_name); 
      holder.tv_phonenumber = (TextView) v.findViewById(R.id.tv_phonenumber); 
      holder.iv_photoid = (ImageView) v.findViewById(R.id.iv_photo); 
      v.setTag(holder); 
     } 
     else { 
      holder = (ViewHolder) v.getTag(); 
     } 

     Contact contact = getItem(position); 
     holder.tv_name.setText(contact.getName()); 
     holder.tv_phonenumber.setText(contact.getPhoneNumber()); 

     Bitmap bm = openPhoto(contact.getPhotoId()); 
     if (bm != null) { 
      holder.iv_photoid.setImageBitmap(bm); 
     } 
     else { 
      holder.iv_photoid.setImageDrawable(getResources() 
        .getDrawable(R.drawable.ic_item_profile_medium)); 
     } 

     return v; 
    } 

    private Bitmap openPhoto(long contactId) { 
     Uri contactUri = ContentUris.withAppendedId(Contacts.CONTENT_URI, contactId); 
     InputStream input = ContactsContract.Contacts 
       .openContactPhotoInputStream(_context.getContentResolver(), 
         contactUri); 

     if (input != null) { 
      return BitmapFactory.decodeStream(input); 
     } 

     return null; 
    } 

    private class ViewHolder { 
     ImageView iv_photoid; 
     TextView tv_name; 
     TextView tv_phonenumber; 
    } 

} 

分配適配器ListView在onCreate()或您的活動onResume()。

ListView contactList = (ListView) findViewById(R.id.list_contact); 
ContactsAdapter adapter = new ContactsAdapter(YourActivity.this, 
      R.layout.list_contact, getContactList()); 
contactList.setAdapter(adapter); 

我發現上面的來源使用谷歌搜索，但我不記得哪裏是參考網站。對不起。

使用以下代碼獲取所有使用的聯繫人ContentResolver。 Reference Link

ContentResolver cr = getContentResolver(); 
     Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, 
       null, null, null, null); 
     if (cur.getCount() > 0) { 
      while (cur.moveToNext()) { 
        String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID)); 
        String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 
        if (Integer.parseInt(cur.getString(
         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)); 
         Toast.makeText(NativeContentProvider.this, "Name: " + name + ", Phone No: " + phoneNo, Toast.LENGTH_SHORT).show(); 
        } 
        pCur.close(); 
       } 
      } 
     }
