Android從聯系人列表中獲取電話號碼

Question

我有這些代碼，它們基本上使用ListView在聯系人列表中顯示姓名，並且我想在單擊每個名稱時獲取其電話號碼：

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方法中

    GetColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)

返回-1，因此我無法使用此方法獲取電話號碼。

我還嘗試打印出光標c所有列，它返回34列，但是似乎與電話號碼相關的唯一列是HasPhoneNumber 。

那么問題出在哪里，我該如何解決？ 謝謝！

更新版本，更改了傳遞給構造myCursorAdapter的String數組的位置：

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();
        }
    });

我想更新后的代碼將在ListView中顯示電話號碼，但是我收到一條錯誤消息，說“列'data1'不存在”。

您可以使用以下代碼在Recyclerview中獲取聯系人列表。

  List<ContactVO> contactVOList = new ArrayList();

  String[] projection = new String[]{ContactsContract.Contacts._ID, ContactsContract.Data.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.PHOTO_URI};
    Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, projection, null, null,
            ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");
    List<ContactVO> userList = new ArrayList<>();

    String lastPhoneName = " ";
    if (phones.getCount() > 0) {
        while (phones.moveToNext()) {
            String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
            String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
            String contactId = phones.getString(phones.getColumnIndex(ContactsContract.Contacts._ID));
            String photoUri = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI));
            if (!name.equalsIgnoreCase(lastPhoneName)) {
                lastPhoneName = name;
                ContactVO user = new ContactVO();
                user.setContactName(phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)));
                user.setContactNumber(phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));
                userList.add(user);
                Log.d("getContactsList", name + "---" + phoneNumber + " -- " + contactId + " -- " + photoUri);
            }
        }
    }
    phones.close();

    AllContactsAdapter contactAdapter = new AllContactsAdapter(userList, getApplicationContext());
    rvContacts.setLayoutManager(new LinearLayoutManager(PhoneDirectoryActivity.this));
    rvContacts.setAdapter(contactAdapter);

在ContactVO類文件下面；

public class ContactVO
{
private String ContactImage;
private String ContactName;
private String ContactNumber;

public String getContactImage() {
    return ContactImage;
}

public void setContactImage(String contactImage) {
    this.ContactImage = ContactImage;
}

public String getContactName() {
    return ContactName;
}

public void setContactName(String contactName) {
    ContactName = contactName;
}

public String getContactNumber() {
    return ContactNumber;
}

public void setContactNumber(String contactNumber) {
    ContactNumber = contactNumber;
}
}

以下是AllContactsAdapter文件

    public class AllContactsAdapter extends RecyclerView.Adapter<AllContactsAdapter.ContactViewHolder> {

    private List<ContactVO> contactVOList;
    private Context mContext;
    private SparseBooleanArray itemStateArray = new SparseBooleanArray();

    public AllContactsAdapter(List<ContactVO> contactVOList, Context mContext) {
        this.contactVOList = contactVOList;
        this.mContext = mContext;
    }

    @Override
    public ContactViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(mContext).inflate(R.layout.single_contact_view, null);
        ContactViewHolder contactViewHolder = new ContactViewHolder(view);
        return contactViewHolder;
    }

    @Override
    public void onBindViewHolder(ContactViewHolder holder, int position) {
        ContactVO contactVO = contactVOList.get(position);
        holder.tvContactName.setText(contactVO.getContactName());
        holder.tvPhoneNumber.setText(contactVO.getContactNumber());

        holder.bind(position);

        holder.cbContact.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                int adapterPosition = position;
                if (!itemStateArray.get(adapterPosition, false)) {
                    holder.cbContact.setChecked(true);
                    contactsList.add(holder.tvPhoneNumber.getText().toString());
                    itemStateArray.put(adapterPosition, true);
                } else {
                    holder.cbContact.setChecked(false);
                    itemStateArray.put(adapterPosition, false);
                    contactsList.remove(holder.tvPhoneNumber.getText().toString());
                }
            }
        });
    }

    @Override
    public int getItemCount() {
        return contactVOList.size();
    }

    public class ContactViewHolder extends RecyclerView.ViewHolder {

        ImageView ivContactImage;
        TextView tvContactName;
        TextView tvPhoneNumber;
        CheckBox cbContact;

        public ContactViewHolder(View itemView) {
            super(itemView);
            ivContactImage = itemView.findViewById(R.id.ivContactImage);
            tvContactName = itemView.findViewById(R.id.tvContactName);
            tvPhoneNumber = itemView.findViewById(R.id.tvPhoneNumber);
            cbContact = itemView.findViewById(R.id.cbContact);
        }
        void bind(int arg1) {
            // use the sparse boolean array to check
            if (!itemStateArray.get(arg1, false)) {
                cbContact.setChecked(false);
            } else {
                cbContact.setChecked(true);
            }
        }
    }
}

Answer 2

首先，在AndroidManifest.xml中添加此行以獲取用戶權限。

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

實現聯系按鈕

        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);

            }
        });

您必須重寫onActivityResult（），該方法將類似於以下內容寫入onCreate（）方法的外部

    @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;
    }

}

Answer 3

ContactsContract Android API將有關聯系人的Data例如電話號碼）存儲在Data表中，而不是Contacts表中。

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

更新 -這是您代碼的固定版本（未經測試）：

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();
    }
});

Answer 4

它返回-1，因為您不從數據庫請求列ContactsContract.CommonDataKinds.Phone.NUMBER ：

new String[] {ContactsContract.Contacts.DISPLAY_NAME}

ContactsContract.Contacts.DISPLAY_NAME是您要求的唯一字段。

為了獲得電話號碼，您首先需要將其包括在要從數據庫中獲取的列的列表中：

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

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