Question

在我的应用程序中，我创建了一个编辑文本视图和三个按钮。当用户点击“添加更多联系人”按钮时，它将添加另一个编辑文本视图，当用户点击“添加联系人”时，这将带他到电话簿的联系人，从那里他可以选择他想要发送的联系人短信。我已经编写了所有这些程序，但我不知道如何在没有用户确认的情况下自动向所有用户发送消息，只需按下“发送消息”按钮。我试过SMSManager但它已经折旧了。请建议我。

public class MainActivity extends Activity {
    private Button btn_cntct;
    public int REQUESTCODE = 1;
    private LinearLayout layoutLinear;
    private Button btn_addmore_cntct;
    private int id = 1;

    Button b_alert;

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

        // defining button elements for picking contacts from phone-book
        btn_cntct = (Button) findViewById(R.id.bpickperson);
        btn_cntct.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                // using Intent for fetching contacts from phone-book
                Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
                intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE);
                startActivityForResult(intent, REQUESTCODE);
            }

        });
        // defining button and edit-text values for adding mutli edit-texts
        // views
        layoutLinear = (LinearLayout) findViewById(R.id.mLayout);
        btn_addmore_cntct = (Button) findViewById(R.id.baddmorecontacts);
        btn_addmore_cntct.setOnClickListener(OnClick());
        EditText editview = new EditText(this);
        editview.setText("Add more");

    }

    // implementing OnClickListener OnClick() method for "btn_addmore_cntct"
    // button
    private OnClickListener OnClick() {
        // TODO Auto-generated method stub
        // changing return type "null" to "new OnClickListner"
        return new OnClickListener() {

            @Override

                tab.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
                        LayoutParams.WRAP_CONTENT));
                // setting id for edit-text views
                tab.setId(id);
                // and increment
                id++;

                // adding (0) to display edit-text view on the top
                layoutLinear.addView(tab, 0);
                tab.requestFocus();
                // for sending sms

您需要发送数字的this

SmsManager.getDefault().sendTextMessage("NUMBER",
                                null, "TEXT_TO_SEND", null, null);

向多个用户发送短信
