Android从联系人列表中获取电话号码

概述我有这些代码基本上使用ListView来显示联系人列表中的名称,我想在单击每个单一名称时获取他们的电话号码：finalContentResolvercr=getContentResolver();finalCursorc=cr.query(ContactsContract.Contacts.CONTENT_URI,null,null,null,null);myCursorAdapter=new

我有这些代码基本上使用ListVIEw来显示联系人列表中的名称,我想在单击每个单一名称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,但唯一与电话号码相关的列是HasPhoneNumber.

那么问题在哪里,我该如何解决？谢谢！

更新版本,其中传递给构造myCursorAdapter的String数组已更改：

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();        }    });

我想更新后的代码会在ListVIEw中显示电话号码,但我收到一条错误,说“列’data1’不存在”.

解决方法:

ContactsContract AndroID API在“数据”表中存储有关电话号码等联系人的数据,而不是“联系人”表.

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();    }});
