Android从联系人列表中获取电话号码

Question

我有这些代码，它们基本上使用 ListView 来显示联系人列表中的姓名，我想在单击每个姓名时获取他们的电话号码：

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，因此我无法使用此方法获取电话号码。

我还尝试打印出光标 c 的所有列，它返回 34 列，但似乎与电话号码相关的唯一列是 HasPhoneNumber。

那么问题出在哪里，我该如何解决？谢谢！

更新版本，其中 String 数组传递给构造 myCursorAdapter 发生变化：

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();
        }
    });

我想更新后的代码将在 ListView 中显示电话号码，但我收到一条错误消息“列 'data1' 不存在”。

首先在 AndroidManifest.xml 中添加这一行以获得用户的许可。

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

实现联系按钮

        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);

            }
        });

你必须重写 onActivityResult() 它将被写入 onCreate() 方法的外部 类似这个

    @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;
    }

}

您可以使用以下代码在 Recyclerview 中获取联系人列表；

  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);

ContactVO类文件下面；

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 3

ContactsContract Android API 将联系人数据（例如电话号码）存储在Data 表中，而不是Contacts 表中。

仔细阅读：https://developer.android.com/reference/android/provider/ContactsContract.html。

更新 - 这是您的代码的固定版本（未经测试）：

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 因为您没有从 DB 请求列 ContactsContract.CommonDataKinds.Phone.NUMBER：

new String[] {ContactsContract.Contacts.DISPLAY_NAME}

ContactsContract.Contacts.DISPLAY_NAME 是您请求的唯一字段。

为了能够获取电话号码，您首先需要将其包含在要从 DB 获取的列列表中：

新字符串[] {ContactsContract.Contacts.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone.NUMBER}

现在您必须覆盖适配器的getView，以便将名称设置到列表行的 textView 中。之后，您的 onItemClick 将按预期工作

Answer 5

此答案只是上述答案的一个小更新。它可能对某人有所帮助。

StarActivityForResult 已弃用。所以我们可以在 Kotlin 中使用下面的模型。

在清单中：

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

请同时实现运行时权限。我的代码中还没有完成。

用于处理结果的以下行：

    private val openContacts = registerForActivityResult(ActivityResultContracts.PickContact()) {

    val contactData: Uri = it
    val phone: Cursor? = contentResolver.query(contactData!!, null, null, null, null)
    if (phone!!.moveToFirst()) {
        val contactName: String = phone.getString(phone.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME))

        // To get number - runtime permission is mandatory.
        val id: String = phone.getString(phone.getColumnIndex(ContactsContract.Contacts._ID))
        if (phone.getString(phone.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)).toInt() > 0) {
            val phones = contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + id, null, null)
            while (phones!!.moveToNext()) {
                val phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))
                Log.d("## Number", phoneNumber)
            }
            phones!!.close()
        }

        Log.d("## Contact Name", contactName)
    }

}

打开联系人：

button.setOnClickListener {
        openContacts.launch(null)
    }
