我想在另一个calss中运行发送短信但是当我启动虚拟设备时它“不幸地......已经停止了”。
这是SensSms
public class SendSmsClass extends Activity {
public void sendSMS(String phoneNumber,String message) {
SmsManager smsManager = SmsManager.getDefault();
String SENT = "SMS_SENT";
String DELIVERED = "SMS_DELIVERED";
SmsManager sms = SmsManager.getDefault();
ArrayList<String> parts = sms.divideMessage(message);
int messageCount = parts.size();
Log.i("Message Count", "Message Count: " + messageCount);
ArrayList<PendingIntent> deliveryIntents = new ArrayList<PendingIntent>();
ArrayList<PendingIntent> sentIntents = new ArrayList<PendingIntent>();
PendingIntent sentPI = PendingIntent.getBroadcast(this, 0, new Intent(SENT), 0);
PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0, new Intent(DELIVERED), 0);
for (int j = 0; j < messageCount; j++) {
sentIntents.add(sentPI);
deliveryIntents.add(deliveredPI);
}
// ---when the SMS has been sent---
registerReceiver(new BroadcastReceiver() {
@Override
public void onReceive(Context arg0, Intent arg1) {
switch (getResultCode()) {
case Activity.RESULT_OK:
Toast.makeText(getBaseContext(), "دستور ارسال شد ، منتظر دریافت پاسخ باشید",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
Toast.makeText(getBaseContext(), "Generic failure",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NO_SERVICE:
Toast.makeText(getBaseContext(), "عدم وجود سیگنال",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NULL_PDU:
Toast.makeText(getBaseContext(), "خطای نامشخص",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_RADIO_OFF:
Toast.makeText(getBaseContext(), "Radio off",
Toast.LENGTH_SHORT).show();
break;
}
}
}, new IntentFilter(SENT));
// ---when the SMS has been delivered---
registerReceiver(new BroadcastReceiver() {
@Override
public void onReceive(Context arg0, Intent arg1) {
switch (getResultCode()) {
case Activity.RESULT_OK:
Toast.makeText(getBaseContext(), "دستور به دستگاه رسید",
Toast.LENGTH_SHORT).show();
break;
case Activity.RESULT_CANCELED:
Toast.makeText(getBaseContext(), "دستور به دستگاه نرسید",
Toast.LENGTH_SHORT).show();
break;
}
}
}, new IntentFilter(DELIVERED));
smsManager.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);
/* sms.sendMultipartTextMessage(phoneNumber, null, parts, sentIntents, deliveryIntents); */
}
}
我从另一个活动调用此类来发送此代码中的短信：
public class AdminNumber extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_admin_number);
SendSmsClass ssc = new SendSmsClass();
ssc.sendSMS("3432", "test");
这是我的logcat：

但是当我在一个类文件中使用我的代码时，它运行得很好 什么是我的错？
答案 0 :(得分：0)
您应该从SendSms类中删除extends Activity，它确实有效..立即尝试
而且你需要发送内容的上下文然后你可以从AdminNumber Activity传递它的构造函数，
请参阅修改后的代码
public class SendSmsClass {
Context c;
SendSmsClass(Context c){
this.c=c;
}
public void sendSMS(String phoneNumber,String message) {
SmsManager smsManager = SmsManager.getDefault();
String SENT = "SMS_SENT";
String DELIVERED = "SMS_DELIVERED";
SmsManager sms = SmsManager.getDefault();
ArrayList<String> parts = sms.divideMessage(message);
int messageCount = parts.size();
Log.i("Message Count", "Message Count: " + messageCount);
ArrayList<PendingIntent> deliveryIntents = new ArrayList<PendingIntent>();
ArrayList<PendingIntent> sentIntents = new ArrayList<PendingIntent>();
PendingIntent sentPI = PendingIntent.getBroadcast(c, 0, new Intent(SENT), 0);
PendingIntent deliveredPI = PendingIntent.getBroadcast(c, 0, new Intent(DELIVERED), 0);
for (int j = 0; j < messageCount; j++) {
sentIntents.add(sentPI);
deliveryIntents.add(deliveredPI);
}
// ---when the SMS has been sent---
registerReceiver(new BroadcastReceiver() {
@Override
public void onReceive(Context arg0, Intent arg1) {
switch (getResultCode()) {
case Activity.RESULT_OK:
Toast.makeText(c, "دستور ارسال شد ، منتظر دریافت پاسخ باشید",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
Toast.makeText(c, "Generic failure",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NO_SERVICE:
Toast.makeText(c, "عدم وجود سیگنال",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NULL_PDU:
Toast.makeText(c, "خطای نامشخص",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_RADIO_OFF:
Toast.makeText(c, "Radio off",
Toast.LENGTH_SHORT).show();
break;
}
}
}, new IntentFilter(SENT));
// ---when the SMS has been delivered---
c.registerReceiver(new BroadcastReceiver() {
@Override
public void onReceive(Context arg0, Intent arg1) {
switch (getResultCode()) {
case Activity.RESULT_OK:
Toast.makeText(c, "دستور به دستگاه رسید",
Toast.LENGTH_SHORT).show();
break;
case Activity.RESULT_CANCELED:
Toast.makeText(c, "دستور به دستگاه نرسید",
Toast.LENGTH_SHORT).show();
break;
}
}
}, new IntentFilter(DELIVERED));
smsManager.sendTextMessage（phoneNumber，null，message，sentPI，deliveredPI）; / * sms.sendMultipartTextMessage（phoneNumber，null，parts，sentIntents，deliveryIntents）; * / }
并在AdminNumber中：
SendSmsClass ssc = new SendSmsClass(AdminNumber.this);
ssc.sendSMS("3432", "test");
如果您需要上下文，请在任何地方使用 c
祝你好运
