我正在制作一个应用程序，在该应用程序中我正在访问电话簿，然后选择一个联系人向该特定收件人发送短信，但是每当我尝试发送短信时，我都会在我的代码的 Catch 块中给出错误消息失败案例：" "短信失败，请稍后再试！“”

注意：我也在真实设备上尝试过这个，并且在那里遇到同样的问题......以及。

联系.java::

  public interface Contact {

public int getId();

public String getName();

public List<RawContact> getRawContacts();

}

生日编辑器.java::

public class BirthdayEditor extends Activity implements OnItemClickListener {
private static final int CREATE_BIRTHDAY = 0;
private static final int EDIT_BIRTHDAY = 1;
private static final int DELETE_BIRTHDAY = 2;
private ImageButton saveGreeting;

public static final String CONTACT_ID = "contact_id";
private static final int NO_CONTACT_ID = Integer.MIN_VALUE;

private TextView name;
private ListView list;
private Database db;
private Contact contact;

ImageButton buttonSend;
EditText textSMS;

private Map<String, AuthenticatorDescription> map = new LinkedHashMap<String, AuthenticatorDescription>();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.editor);

    // bind GUI components
    this.name = (TextView) findViewById(R.id.editor_name);
    this.list = (ListView) findViewById(R.id.editor_list);

    // check if contact id is valid
    this.db = new Database(getContentResolver());
    final int contactId = getIntent().getIntExtra(CONTACT_ID, NO_CONTACT_ID);
    this.contact = this.db.getContact(contactId);
    if (this.contact == null) {
        finish();
    }
    this.name.setText(this.contact.getName());

    // pre-load information about all account types
    AuthenticatorDescription[] authTypes = AccountManager.get(this).getAuthenticatorTypes();
    for (AuthenticatorDescription authDesc : authTypes) {
        this.map.put(authDesc.type, authDesc);
    }

    // bind list events
    this.list.setOnItemClickListener(this);
    this.list.setOnCreateContextMenuListener(this);

    // create the GUI
    updateView();               

    buttonSend = (ImageButton) findViewById(R.id.buttonSend);
    textSMS = (EditText) findViewById(R.id.editTextSMS);
    buttonSend.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

          String recepient = contact.getName().toString();
              Log.d(LOG_TAG, "onClick(" + recepient + ")");
          String sms = textSMS.getText().toString();

          try {
            SmsManager smsManager = SmsManager.getDefault();
            smsManager.sendTextMessage(recepient, null, sms, null, null);
            Toast.makeText(getApplicationContext(), "SMS Sent!",
                        Toast.LENGTH_LONG).show();
          } catch (Exception e) {
            Toast.makeText(getApplicationContext(),
                "SMS faild, please try again later!",
                Toast.LENGTH_LONG).show();
            e.printStackTrace();
          }

        }
    });
}

@吉米希尔

你仍然得到接收者的名字，因为你正在使用你的 Contact.java 类的getName()方法下面的行：

    String recepient = contact.getName().toString();

但是要使用getRawContacts()获取数字代替名称，您只需将上面的行替换为下面的行，因为通过使用这一行，您可以从代码中的联系人列表中获取原始联系人，只需再次检查 Contact.java：

    String recepient = contact.getRawContacts().toString();

我相信它会对你有用，如果出现任何问题，请告诉我......
