标签： android android-contacts

我想从我的联系人列表中选择一个联系人。 我读了很多解决方案和研究几周，但所有文章都没有正常工作。 一些代码如下：

Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(intent, PICK_CONTACT);

//并且在activityresult中：

if (resultCode == Activity.RESULT_OK) {
            Uri contactData = data.getData();
            Cursor c =  managedQuery(contactData, null, null, null, null);
            if (c.moveToFirst()) {
              String name = c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
              tv1.setText(name);
            }
          }

或此代码获取所有联系人但我不能拥有联系人数量：

String[] contacts = new String[] {People.NAME, People.NUMBER};       
Uri contentUri = People.CONTENT_URI;        
Cursor cursor = managedQuery(contentUri, contacts, null, null, null);                 
String textContacts = "";                 
if (cursor.moveToFirst()) {         
    String myname = null;         
    String mynumber = null;         
    do {          
        textContacts = textContacts + cursor.getString(cursor.getColumnIndex(People.NAME)) + " : " + cursor.getString(cursor.getColumnIndex(People.NUMBER)) + "\n";         
    } while (cursor.moveToNext()); 
tv1.setText(textContacts);
}

尝试以下代码可以帮助您：

  // You need below permission to read contacts
  <uses-permission android:name="android.permission.READ_CONTACTS"/>

  // Declare
  static final int PICK_CONTACT=1;

  Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
  startActivityForResult(intent, PICK_CONTACT);

  //code 
  @Override
 public void onActivityResult(int reqCode, int resultCode, Intent data) {
 super.onActivityResult(reqCode, resultCode, data);

 switch (reqCode) {
 case (PICK_CONTACT) :
   if (resultCode == Activity.RESULT_OK) {

     Uri contactData = data.getData();
     Cursor c =  managedQuery(contactData, null, null, null, null);
     if (c.moveToFirst()) {


         String id =c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts._ID));

         String hasPhone =c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));

           if (hasPhone.equalsIgnoreCase("1")) {
          Cursor phones = getContentResolver().query( 
                       ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null, 
                       ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ id, 
                       null, null);
             phones.moveToFirst();
              cNumber = phones.getString(phones.getColumnIndex("data1"));
             System.out.println("number is:"+cNumber);
           }
         String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));


     }
   }
   break;
 }
 }

使用Intent.ACTION_PICK访问手机联系人。代码为

Uri uri = Uri.parse("content://contacts");
Intent intent = new Intent(Intent.ACTION_PICK, uri);
intent.setType(Phone.CONTENT_TYPE);
startActivityForResult(intent, REQUEST_CODE);

哪里

private static final int REQUEST_CODE = 1;

使用onActivityResult（）方法访问所选联系人。代码为

@Override
    protected void onActivityResult(int requestCode, int resultCode,
            Intent intent) {
        if (requestCode == REQUEST_CODE) {
            if (resultCode == RESULT_OK) {
                Uri uri = intent.getData();
                String[] projection = { Phone.NUMBER, Phone.DISPLAY_NAME };

                Cursor cursor = getContentResolver().query(uri, projection,
                        null, null, null);
                cursor.moveToFirst();

                int numberColumnIndex = cursor.getColumnIndex(Phone.NUMBER);
                String number = cursor.getString(numberColumnIndex);

                int nameColumnIndex = cursor.getColumnIndex(Phone.DISPLAY_NAME);
                String name = cursor.getString(nameColumnIndex);

                Log.d(TAG, "ZZZ number : " + number +" , name : "+name);

            }
        }
    };

添加将联系人数据读取到应用程序清单的权限。

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

在您的活动中使用Intent.Action_Pick，如下所示

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

然后覆盖onActivityResult() 

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // check whether the result is ok
        if (resultCode == RESULT_OK) {
            // Check for the request code, we might be usign multiple startActivityForReslut
            switch (requestCode) {
            case RESULT_PICK_CONTACT:
               Cursor cursor = null;
        try {
            String phoneNo = null ;
            String name = null;           
            Uri uri = data.getData();            
            cursor = getContentResolver().query(uri, null, null, null, null);
            cursor.moveToFirst();           
            int  phoneIndex =cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
            phoneNo = cursor.getString(phoneIndex); 

            textView2.setText(phoneNo);
        } catch (Exception e) {
            e.printStackTrace();
        }
                break;
            }
        } else {
            Log.e("MainActivity", "Failed to pick contact");
        }
    }

这将检查出来

以下是我实施的内容：

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

    Log.i(LOG_TAG, "get Contact List: Fetching complete contact list");

    ArrayList<String> contact_names = new ArrayList<String>();

    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 (cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER.trim())).equalsIgnoreCase("1"))
            {
                if (name!=null){
                    //contact_names[i]=name;

                    Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",new String[]{id}, null);
                    while (pCur.moveToNext()) 
                    {
                        String PhoneNumber = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                        PhoneNumber = PhoneNumber.replaceAll("-", "");
                        if (PhoneNumber.trim().length() >= 10) {
                            PhoneNumber = PhoneNumber.substring(PhoneNumber.length() - 10);
                        }
                        contact_names.add(name + ":" + PhoneNumber);

                        //i++;
                        break;
                    }
                    pCur.close();
                    pCur.deactivate();
                    // i++;
                }
            }
        }
        cur.close();
        cur.deactivate();
    }

    String[] contactList = new String[contact_names.size()]; 

    for(int j = 0; j < contact_names.size(); j++){
        contactList[j] = contact_names.get(j);
    }

    return contactList;
}

您可以调用此功能，也可以使用AutoCompleteTextView显示和选择联系人姓名和10位数字。这个函数返回String数组，你可以直接返回arrayList并删除最后一个for循环。

如果您想在点击或焦点事件中从联系人列表中选择联系人，请复制此代码并粘贴到您的活动中。

  • 编辑文本的焦点事件： 

     phoneNo.setOnFocusChangeListener(new OnFocusChangeListener()
  {   public void onFocusChange(View v, boolean hasFocus) 
      {
         Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
         startActivityForResult(intent,PICK_CONTACT );//PICK_CONTACT is private static final int, so declare in activity class
   } });

  • 获取联系人姓名和电话的功能：

      public void onActivityResult(int reqCode, int resultCode, Intent data)
   {
     super.onActivityResult(reqCode, resultCode, data);

        switch(reqCode){
           case (PICK_CONTACT):
             if (resultCode == Activity.RESULT_OK)
             {
                 Uri contactData = data.getData();
                 Cursor c = managedQuery(contactData, null, null, null, null);
              if (c.moveToFirst()) {
              String id =   
                c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts._ID));

              String hasPhone =
              c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));

              if (hasPhone.equalsIgnoreCase("1")) {
             Cursor phones = getContentResolver().query( 
                          ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null, 
                          ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ id, 
                          null, null);
                phones.moveToFirst();
                String phn_no = phones.getString(phones.getColumnIndex("data1"));
                String name = c.getString(c.getColumnIndex(StructuredPostal.DISPLAY_NAME));
               Toast.makeText(this, "contact info : "+ phn_no+"\n"+name, Toast.LENGTH_LONG).show();

              }
                }

此代码适用于手机号码联系人，不适用于电子邮件或其他内容。我发现这个代码最简单。如果有任何问题，请告诉我。

使用电话数据类型的选择意图启动活动：

findViewById(R.id.choose_contact_button).setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
            Intent pickContact = new Intent(Intent.ACTION_PICK, ContactsContract.CommonDataKinds.Phone.CONTENT_URI);
            startActivityForResult(pickContact, PICK_CONTACT_REQUEST);
      }
 });

现在设置onAcitivityResult（）; 

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent intent){
        switch (requestCode){
            case PICK_CONTACT_REQUEST:
                if (resultCode == RESULT_OK){
                    Uri contactUri = intent.getData();
                    Cursor nameCursor = getContentResolver().query(contactUri, null, null, null, null);
                    if (nameCursor.moveToFirst()){
                        String name = nameCursor.getString(nameCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
                        String number = nameCursor.getString(nameCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                        ((EditText)findViewById(R.id.person_name)).setText(name);

如果没有清单或运行时权限，您可以尝试此操作。

从联系人应用中提取姓名和联系电话。通过此代码，联系人应用程序还将显示联系人姓名下方的数字。

代码是从联系人应用中选择单个姓名和号码。

private void openContactSelectionIntent() {
        Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
        intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_TYPE);
        startActivityForResult(Intent.createChooser(intent, "Select Contact"), RC_SELECT_CONTACT);
    }

这是onActivityResult方法的代码

Uri uri1 = data.getData();
                Cursor c = managedQuery(uri1, null, null, null, null);
                if (c.moveToFirst()) {
                    String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                    System.out.println("name is: " + name);

                }



                Cursor cursor = getContentResolver().query(uri1, null, null, null, null);
                if (null == cursor) return;
                try {
                    while (cursor.moveToNext()) {
                        String number = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
                        System.out.println("number is "+number);
                    }
                }catch (Exception e){
                    e.printStackTrace();
                }finally {
                    cursor.close();
                }

如果联系人确实有多个号码，您也可以尝试此解决方案

Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.CommonDataKinds.Phone.CONTENT_URI);
            startActivityForResult(intent , REQUEST_CODE_ADDRESS_BOOK

);

，然后显示活动结果：

@Override
    public void onActivityResult(int reqCode, int resultCode, Intent data) {
        super.onActivityResult(reqCode, resultCode, data);

        switch (reqCode) {
            case (REQUEST_CODE_ADDRESS_BOOK):
                if (resultCode == Activity.RESULT_OK) {
                    Uri contactData = data.getData();
                    Cursor c =  getContentResolver().query(contactData, null, null, null, null);

                    c.moveToFirst();
                    String phoneNumber =  c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                    c.close();
                }
                break;
        }
    }

然后，该号码将在phoneNumber变量中。

您可以使用 LiveData 从“联系人”列表中获取姓名和电话号码，还可以检查“联系人”权限。

ReadContactsViewModel 

public class ReadContactsViewModel extends AndroidViewModel {
private MutableLiveData<ArrayList<Contat>> contactList;

public ReadContactsViewModel(@NonNull Application application) {
    super(application);
}


public MutableLiveData<ArrayList<Contat>> getContacts(Context context) {
    if (contactList == null) {
        String phoneNumber;
        ArrayList<Contat> savedContacts = new ArrayList<>();
        Contat savedContact;
        ContentResolver cr = context.getContentResolver();
        ArrayList<String> idList = new ArrayList<>();
        if (cr != null) {
            Cursor cur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, "UPPER(" + ContactsContract.Contacts.DISPLAY_NAME + ") ASC");
            if (cur != null) {
                while (cur.moveToNext()) {


                    phoneNumber = cur.getString(cur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                    if (phoneNumber.length() > 9) {
                        savedContact = new Contat();
                        phoneNumber = phoneNumber.replaceAll("\\s+", "");
                        String id = phoneNumber.substring(phoneNumber.length() - 7);//last 7 digits of numbers
                        String name = cur.getString(cur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
                        String photoThumb = cur.getString(cur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_THUMBNAIL_URI));
                        savedContact.setNumber(phoneNumber);
                        savedContact.setName(name);

                        if (!idList.contains(id)) {
                            savedContacts.add(savedContact);
                            idList.add(id);
                        }
                    }
                }

                cur.close();
                idList.clear();
            }

        }

        contactList = new MutableLiveData<>();
        contactList.setValue(savedContacts);
    }
    return contactList;
}

现在您可以获取此savedContactList或将其发送到服务器，我还使用了权限TedPermission库，您可以使用任何喜欢的人

    private void syncContacts() {
    ReadContactsViewModel readContactsViewModel = ViewModelProviders.of(this)
            .get(ReadContactsViewModel.class);

    Observer<ArrayList<Contat>> readContactsObserver =
            new Observer<ArrayList<Contat>>() {
                @Override
                public void onChanged(@Nullable ArrayList<Contat> savedContactList) {
                    assert savedContactList != null;
                    for (int i = 0; i < savedContactList.size(); i++) {
                        Contat savedContact = savedContactList.get(i);

                        contactPostList.add(new Contat(savedContact.getName(), savedContact.getNumber()));
                    }
                    youractiviy.this.postContactsToServer();

                }
            };
    contactPermissionListener = new PermissionListener() {
        @Override
        public void onPermissionGranted() {


            readContactsViewModel.getContacts(youractiviy.this)
                    .observe(youractiviy.this,
                            readContactsObserver);


        }

        @Override
        public void onPermissionDenied(ArrayList<String> deniedPermissions) {

        }
    };

    TedPermission.with(this).setPermissionListener(contactPermissionListener).setDeniedMessage(R.string.permission_denied).setPermissions(Manifest.permission.READ_CONTACTS).check();
}

这是我为所有在Kotlin寻找解决方案的人的答案， 不要与“绑定”一词混淆，这只是用于绑定视图。点击“ pickContact”，我们将打开“联系人”应用。

首先在清单文件中添加权限。

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

val RESULT_PICK_CONTACT = 1

binding?.pickContact ->{
            val contactPickerIntent = Intent(
                Intent.ACTION_PICK,
                ContactsContract.CommonDataKinds.Phone.CONTENT_URI
            )
            startActivityForResult(contactPickerIntent, RESULT_PICK_CONTACT)
        }

点击pickContact，我们将打开“联系人”应用， 然后覆盖onActivityResult方法，

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)

    if (resultCode == Activity.RESULT_OK) {
        when (requestCode) {
            RESULT_PICK_CONTACT -> {
                var cursor: Cursor? = null
                try {
                    var phoneNo: String? = null
                    var name: String? = null
                    val uri: Uri? = data?.data
                    cursor = contentResolver.query(uri!!, null, null, null, null)
                    cursor?.moveToFirst()
                    val phoneIndex: Int =
                        cursor!!.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)
                    val phoneContactName: String =
                        cursor!!.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME))
                    phoneNo = cursor?.getString(phoneIndex)
                    et_name.setText(phoneContactName) //setting the contacts name
                    mobile_number.setText(phoneNo) //setting the contacts phone number

                } catch (e: Exception) {
                    e.printStackTrace()
                }
            }
        }
    } else {
        Log.e("ActivityName", "Something went wrong")
    }
}
