People api用于访问已弃用的联系人。您应该使用ContactsContract。

我修改了你的代码，现在工作正常。这里是。

public class MainActivity extends Activity {
public static final int PICK_CONTACT = 1;
private Button btnContacts;
private TextView txtContacts1;
private TextView txtContacts2;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    btnContacts = (Button) findViewById(R.id.btn_contacts);
    txtContacts1 = (TextView) findViewById(R.id.txt_contacts_name);
    btnContacts.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg0) {
            Intent intent = new Intent(Intent.ACTION_PICK);
            intent.setType(ContactsContract.Contacts.CONTENT_TYPE);
            if (intent.resolveActivity(getPackageManager()) != null) {
                startActivityForResult(intent, PICK_CONTACT);
            }
        }
    });
}

@Override
public void onActivityResult(int reqCode, int resultCode, Intent data) {
    super.onActivityResult(reqCode, resultCode, data);
    String cNumber = null;
    switch (reqCode) {
        case (PICK_CONTACT):
            if (resultCode == Activity.RESULT_OK) {

                Uri contactData = data.getData();
                Cursor c = managedQuery(contactData, null, null, null, null);
                if (c.moveToFirst()) {


                    String id = c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts._ID));

                    String hasPhone = c.getString(c.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();
                        cNumber = phones.getString(phones.getColumnIndex("data1"));
                        //System.out.println("number is:" + cNumber);
                    }
                    String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

                    txtContacts1.setText(name + " : " + cNumber);
                }
            }
            break;
    }
}
}
