我有关于在android中发送短信的问题。我有两节课。其中一个是SendMessage.java，另一个是SendingSms.java，我想通过SendingSms.java文件发送我的消息，所以里面有一个sendSms类，我想在SendMessage.java文件中使用这个sendSms函数，但它不能不会。另外我可以使用SendingSms.java中的函数但是当我在其中编写发送sms代码时，它不起作用。有什么问题？
这是我的SendMessage.java中的函数
public void sendMessageButton (View view)
{
//SendingSms send = new SendingSms();
if(who_detail.getText().toString().length()>0 && message_text.getText().toString().length()>0 )
{
sendSMS(who_detail.getText().toString(), message_text.getText().toString());
}
else
{
Toast.makeText(getApplicationContext(), R.string.sendingsms_error, Toast.LENGTH_LONG).show();
}
}
这是我的sendinSms.java
package com.example.stildeneme;
import android.app.Activity;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.telephony.SmsManager;
import android.widget.Toast;
public class SendingSms extends Activity {
public void sendSMS(String telNo, String mesaj)
{
String SENT = "SMS_SENT";
String DELIVERED = "SMS_DELIVERED";
PendingIntent sentPI = PendingIntent.getBroadcast(this, 0, new Intent(SENT), 0);
PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0, new Intent(DELIVERED), 0);
registerReceiver(new BroadcastReceiver() {
@Override
public void onReceive(Context arg0, Intent arg1) {
// TODO Auto-generated method stub
switch(getResultCode())
{
case Activity.RESULT_OK:
Toast.makeText(getBaseContext(), "SMS Gönderildi",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(), "No service",Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NULL_PDU:
Toast.makeText(getBaseContext(), "Null PDU",Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_RADIO_OFF:
Toast.makeText(getBaseContext(), "Radio off",Toast.LENGTH_SHORT).show();
break;
}
}
}, new IntentFilter(SENT));
registerReceiver(new BroadcastReceiver(){
@Override
public void onReceive(Context arg0, Intent arg1) {
switch (getResultCode())
{
case Activity.RESULT_OK:
Toast.makeText(getBaseContext(), "SMS iletildi",
Toast.LENGTH_SHORT).show();
break;
case Activity.RESULT_CANCELED:
Toast.makeText(getBaseContext(), "SMS iletilemedi",
Toast.LENGTH_SHORT).show();
break;
}
}
}, new IntentFilter(DELIVERED));
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(telNo, null, mesaj, sentPI, deliveredPI);
Toast.makeText(getApplicationContext(), telNo.toString() + " - " + mesaj.toString(), Toast.LENGTH_LONG).show();
}
}
顺便说一句，我从SendingSms类扩展了我的SendMessage类。
这是我的logcat

答案 0 :(得分：2)
首先在sendMessage.java中初始化该类
sendinsms sm = new sendinsms（）;
sm.sendsms（您的参数）;
答案 1 :(得分：1)
将该方法设置为您要从另一个活动访问的公共静态。然后 将其称为activity1.sendsms（）;
这就是方法。如果您发布代码将建议您更好的方式...希望这将帮助您。
您好，请使用以下代码。问题是你需要使用Context。
import android.app.Activity;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.widget.Toast;
public class SendingSms extends Activity {
static Context context;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
context=this;
}
public static void sendSMS(String telNo, String mesaj)
{
String SENT = "SMS_SENT";
String DELIVERED = "SMS_DELIVERED";
PendingIntent sentPI = PendingIntent.getBroadcast(context, 0, new Intent(SENT), 0);
PendingIntent deliveredPI = PendingIntent.getBroadcast(context, 0, new Intent(DELIVERED), 0);
context.registerReceiver(new BroadcastReceiver() {
@Override
public void onReceive(Context arg0, Intent arg1) {
// TODO Auto-generated method stub
switch(getResultCode())
{
case Activity.RESULT_OK:
Toast.makeText(context, "SMS Gönderildi",Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
Toast.makeText(context, "Generic failure",Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NO_SERVICE:
Toast.makeText(context, "No service",Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NULL_PDU:
Toast.makeText(context, "Null PDU",Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_RADIO_OFF:
Toast.makeText(context, "Radio off",Toast.LENGTH_SHORT).show();
break;
}
}
}, new IntentFilter(SENT));
context. registerReceiver(new BroadcastReceiver(){
@Override
public void onReceive(Context arg0, Intent arg1) {
switch (getResultCode())
{
case Activity.RESULT_OK:
Toast.makeText(context, "SMS iletildi",
Toast.LENGTH_SHORT).show();
break;
case Activity.RESULT_CANCELED:
Toast.makeText(context, "SMS iletilemedi",
Toast.LENGTH_SHORT).show();
break;
}
}
}, new IntentFilter(DELIVERED));
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(telNo, null, mesaj, sentPI, deliveredPI);
Toast.makeText(context, telNo.toString() + " - " + mesaj.toString(), Toast.LENGTH_LONG).show();
}
}
答案 2 :(得分：1)
首先，您缺少一项权限：
引起：java.lang.SecurityException：发送短信：用户10048没有 android.permission.SEND_SMS 。
其次这个方法不应该是静态的 - 你可能有内存泄漏。
如果SendMessage扩展了SendSms，你应该公开SendSms.sendSms方法，它应该可以工作
你不应该使用：static Context context;
上下文应该是正常的字段。为什么你需要它：＆gt;？您可以使用活动上下文：＆gt;
答案 3 :(得分：0)
你可以通过两种方式做到：
1。将存在该方法的活动的上下文传递到您要调用该方法的其他活动。
2。第二种方法是使方法静态，然后使用classname从其他活动中调用它。操作
<强>例如
Class_Name.method()
