文本消息未发送到数字列表，但仅在指定一个数字时发送

Question

我正在尝试构建一个应用程序，用户可以将location发送到sqlitedatabase中存储的电话号码。我测试了用户可以将location作为文本消息发送到一个电话号码的应用程序，但是现在当我尝试创建list个数字并将其作为参数传递给{不会发送sendTextMessage smsManager作为短信的location方法。到目前为止，我已经尝试了下面给出的代码，

代码

public class Gps4Activity extends AppCompatActivity implements
        GoogleApiClient.OnConnectionFailedListener {

    private static final String LOG_TAG = "PlacesAPIActivity";
    private static final int GOOGLE_API_CLIENT_ID = 0;

    private static final int MY_PERMISSIONS_REQUEST_SEND_SMS =0 ;
    private TextView display;
    private Button location_button,contacts_button;
    //String number="xxxxxxxxxx";
    ArrayList<String> numbers;
    SQLiteDatabase db;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_gps4);
        numbers=new ArrayList<>();
        db = new UserDatabase(this).getReadableDatabase();

当我尝试使用一个电话号码测试应用程序时，评论的行就是那些。另外，假设最初在sqlitedatabase中只有一个电话号码，我点击location_button多次arraylist增加它的大小。例如，如果arraylist下次点击[xxxxxx]时location_button包含元素arraylist，则[xxxxxx,xxxxxx]现在会/// @brief Top-level root element "":BODY /// @brief "":BODY is a complexType. /// /// class BODY operations: /// - BODY* soap_new_BODY(soap*) allocate and default initialize /// - BODY* soap_new_BODY(soap*, int num) allocate array and default initialize values /// - BODY* soap_new_req_BODY(soap*, ...) allocate, set required members /// - BODY* soap_new_set_BODY(soap*, ...) allocate, set all public members /// - BODY::soap_default(soap*) default initialize members /// - int soap_read_BODY(soap*, BODY*) deserialize from a stream /// - int soap_write_BODY(soap*, BODY*) serialize to a stream /// - BODY* BODY::soap_dup(soap*) returns deep copy of BODY, copies the (cyclic) graph structure when a context is provided, or (cycle-pruned) tree structure with soap_set_mode(soap, SOAP_XML_TREE) (use soapcpp2 -Ec) /// - BODY::soap_del() deep deletes BODY data members, use only after BODY::soap_dup(NULL) (use soapcpp2 -Ed) class BODY { public: // BEGIN CHOICE <xs:choice maxOccurs="2"> $int __size_BODY 0:2; class ___union_BODY { $int __union_BODY ; ///< Union union_BODY selector: set to SOAP_UNION_union_BODY_<fieldname> /// Union for choice in BODY. union union_BODY { /// Element reference ":""":LANE.

有人可以帮我解决这个问题吗？

Answer 1

由于sendTextMessage()方法一次只能获取一个数字，因此您需要为列表中的每个数字执行此方法。

据说你应该“循环”List。像这样：

for (String number : numbers) {
    smsManager.sendTextMessage(numbers, null, message, null, null);
}

它基本上是说：

“好吧，让我们先拿一号，把文字消息发送到第一，我会一直这样做，直到我完成。”
