Question

我有一点问题。我无法让我的广播接收器显示任何Toast消息。也许我无法以某种方式触发它，但我的发件人工作。我想知道它是否会触发。

主要课程

 public class Main_Activity extends Activity {


Button buttonSend;
EditText textPhoneNo;
EditText textSMS;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
   Button  buttons = (Button) findViewById(R.id.gett);
    buttonSend = (Button) findViewById(R.id.buttonSend);
    textPhoneNo = (EditText) findViewById(R.id.editTextPhoneNo);
    textSMS = (EditText) findViewById(R.id.editTextSMS);
    EditText edt = (EditText)findViewById(R.id.reciving);


    buttons.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            // TODO Auto-generated method stub
        //  EditText edt = (EditText)findViewById(R.id.reciving);
        //  SmsReceiver obj = new SmsReceiver();
        //  String test = obj.number2;
        //    edt.setText("you stupid result "+test);

        }
    });

    SmsReceiver obj = new SmsReceiver();
//  String test = obj.number2;
 //   edt.setText("you stupid result "+test);





  buttonSend.setOnClickListener(new OnClickListener() {

    public void onClick(View v) {
        // TODO Auto-generated method stub

        String phoneNo = textPhoneNo.getText().toString();
        String sms = textSMS.getText().toString();

        try{
            SmsManager  smsManager = SmsManager.getDefault();
            smsManager.sendTextMessage(phoneNo, null, sms, null, null);


        }catch (Exception e)
        {
            System.out.println("Not send");
        }





    }
})  ;


}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}
 }

SmsReceiver类：

  public class SmsReceiver extends BroadcastReceiver
 {
@Override
public void onReceive(Context context, Intent intent) 
{
    //---get the SMS message passed in---
    Bundle bundle = intent.getExtras();        
    SmsMessage[] msgs = null;
    String str = "";            
    if (bundle != null)
    {
        //---retrieve the SMS message received---
        Object[] pdus = (Object[]) bundle.get("pdus");
        msgs = new SmsMessage[pdus.length];            
        for (int i=0; i<msgs.length; i++){
            msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);                
            str += "SMS from " + msgs[i].getOriginatingAddress();                     
            str += " :";
            str += msgs[i].getMessageBody().toString();
            str += "\n";        
        }
        //---display the new SMS message---
        Toast.makeText(context, str, Toast.LENGTH_SHORT).show();
    }                         
}
 }

如果您希望您的应用程序接收SMS广播，那么您必须在manifest中包含以下权限

<uses-permission android:name="android.permission.RECEIVE_SMS"/>

并将您的SmsReceiver代码更改为：

public class SmsReceiver extends BroadcastReceiver
 {
  @Override
    public void onReceive(Context context, Intent intent) 
    {
       if (intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED"))
           {
              //put your code here....
           }
       else{
             // do something here...
           }
    }
}
