我怎样才能从用户选择的联系人中获取电话号码？

Question

我能得到用户选择的联系人姓名，但不能得到电话号码

在onclick：

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

PICK_CONTACT 只是一个 int 值，它等于我的请求代码

然后：

@Override
protected void onActivityResult(int reqCode, int resultCode, Intent data) {
    super.onActivityResult(reqCode, resultCode, data);
    if (reqCode == PICK_CONTACT) {
        if (resultCode == AppCompatActivity.RESULT_OK) {

            Uri contactData = data.getData();

            Cursor c = getContentResolver().query(contactData, null, null, null, null);
            if (c.moveToFirst()) {
                String name = c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
                     contactadder.setText(name);


                c.close();

            }

这是我工作的一些小插曲，也许可以帮助您找到正确的方向。 Android 数据库交互的文档记录很差，很难找到正确的方式/值。如果您需要更多帮助来理解，请回复。我删除了一些业务相关的数据，所以不会这样编译。只是为了方便发布！
