从联系人Android中获取一个电话号码

Question

嗨，我正试图从联系人列表中获取一个电话号码。我找到了一个代码，它能给我整个联系人列表的电话号码，我只需要点击项目的电话号码。如有任何帮助，我们将不胜感激。谢谢

public void onClick(View v) {
Intent contactPickerIntent = new Intent(Intent.ACTION_PICK,Contacts.CONTENT_URI);
startActivityForResult(contactPickerIntent,CONTACT_PICKER_RESULT);
ContentResolver cr = getActivity().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(getActivity(), phoneNo,Toast.LENGTH_SHORT).show();
                }
            }
        }
    }
}
});

当您在联系人列表中并单击一个联系人时，您将获得Intent.ACTION_PICK意向的结果。

因此，为了处理结果，您必须重写onActivityResult()方法。

您将在onActivityResult()返回的数据Intent对象中收到联系人的查找URI。

所以，你所要做的就是：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if(requestCode == CONTACT_PICKER_RESULT){
        if(resultCode==Activity.RESULT_OK){
            Uri uri = data.getData();
            ContentResolver contentResolver = getContentResolver();
            Cursor contentCursor = contentResolver.query(uri, null, null,null, null);
            if(contentCursor.moveToFirst()){
                String id = contentCursor.getString(contentCursor.getColumnIndexOrThrow(ContactsContract.Contacts._ID));
                String hasPhone =
                        contentCursor.getString(contentCursor.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 contactNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                    Log.i("phoneNUmber", "The phone number is "+ contactNumber);
                }
            }
            super.onActivityResult(requestCode, resultCode, data);
        }
    }
}

然后你只需要对contactNumber上的值做任何你想做的事情。

希望能帮助你。

首先在AndroidManifest.xml中添加此行以获得用户的权限。

移动用户还需要允许此权限。这可以通过设置手动完成

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

现在在按钮点击监听器编写此代码。

        contactsButtton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent contactPickerIntent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
                startActivityForResult(contactPickerIntent,1);
            }
        });

现在从onCreate（）函数的外部。您必须重写onActivityResult（）函数。类似于这个

    @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();
                ContentResolver cr = getContentResolver();
                Cursor cur = cr.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)
                        {
                            // Query phone here. Covered next
                            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;
    }
}
