使用 smsmanager 在警告框中不起作用

Question

smsmanager 不工作，它也没有显示任何错误，它的功能根本不工作，对话框关闭只工作。

Mainactivity.java

公共类 MainActivity 扩展 Activity 实现 FetchDataListener,OnClickListener { 私有静态最终 int ACTIVITY_CREATE=0; 私人 ProgressDialog 对话框； 列表视图 lv; 私有列表项； 私人按钮 btnGetSelected; //私有项目DbAdapter mDbHelper; //private SimpleCursorAdapter dataAdapter;

Answer 1

smsManager.sendTextMessage("phoneNo", null, "sms message", null, null);

“phoneNo”在此指定您要发送短信的号码

好的，包含电话号码或一些需要作为消息发送的文本数据的选定数据是做什么的。看到“phoneNo”是你传递的字符串。如果您输入电话号码，则在您的手机中代替号码，它将如何发送到它将发送的号码。第一个参数是您要发送短信的电话号码。如果您从列表中选择电话号码，请将其放入一个变量并将该变量代替“phoneNo”

如果您想在显示警报时输入数字，那么这里是代码

private void showAlertView(String str) {
    final EditText input = new EditText(YOURACTIVITYNAME.this);
    AlertDialog alert = new AlertDialog.Builder(YOURACTIVITYNAME.this)
    if (TextUtils.isEmpty(str)) {
        alert.setTitle("Not Selected");
        alert.setMessage("No One is Seleceted!!!");
    } else {
        // Remove , end of the name
        String strContactList = str.substring(0, str.length() - 1);

        alert.setTitle("Selected");
        alert.setMessage(strContactList);
    }
    alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
                 String value;

        @Override
        public void onClick(DialogInterface dialog, int which) {
            //sendSMS();

            SmsManager smsManager = SmsManager.getDefault();
            smsManager.sendTextMessage(input.getText().toString(), null, "sms message", null, null);
            dialog.dismiss();
        }
    }).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int whichButton) {
                    // Do nothing.
                }
            }).show();
