Question

我是Android的新手，我尝试通过我的应用程序接收短信。正在发送短信，因此权限应该可以。首先，我想在Toast中显示接收到的SMS文本，但我阅读使用Log会更好。我正在使用它，并且没有BroadcastReciver的任何信号。

我尝试在清单中添加接收器，并记录日志以查看它是否有效，但是日志中没有任何内容

MainActivity：

package pl.edu.pwr.student.a235420_ks_a5;

import android.Manifest;
import android.content.Context;
import android.content.pm.PackageManager;

public class MainActivity extends AppCompatActivity {
    private Button importSimData;
    private Button sendMessage;
    private EditText smsMessagePhoneNumber;
    private EditText smsMessageText;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        importSimData = findViewById(R.id.button1);
        sendMessage = findViewById(R.id.button2);
        smsMessagePhoneNumber = findViewById(R.id.editText1);
        smsMessageText = findViewById(R.id.editText2);

        SmsReceiver myReciver = new SmsReceiver();

        Log.i("MAIN_ACTIV", "On create");


        importSimData.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.READ_PHONE_STATE)

                            Toast.LENGTH_LONG).show();

                    TelephonyManager tm = (TelephonyManager) MainActivity.this.getSystemService(Context.TELEPHONY_SERVICE);

                    int phoneType = tm.getPhoneType();
                    int phoneCallState = tm.getCallState();
                    int phoneNetworkType = tm.getDataNetworkType();
                    String phoneSubscriberId = tm.getSubscriberId();
                    Toast.makeText(MainActivity.this, String.valueOf(phoneType),
                            Toast.LENGTH_LONG).show();
                    Toast.makeText(MainActivity.this, String.valueOf(phoneCallState ),
                            Toast.LENGTH_LONG).show();
                    Toast.makeText(MainActivity.this, String.valueOf( phoneNetworkType),
                            Toast.LENGTH_LONG).show();
                    Toast.makeText(MainActivity.this, phoneSubscriberId,
                            Toast.LENGTH_LONG).show();
                }
            }
        });

    sendMessage.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.SEND_SMS)
                    != PackageManager.PERMISSION_GRANTED) {
                //NO permission
                Toast.makeText(MainActivity.this, "NO permission!",
                        Toast.LENGTH_LONG).show();
                Toast.makeText(MainActivity.this, "Add permissions in settings",

            else {
                //you have
                String phoneNumber = smsMessagePhoneNumber.getText().toString();
                String smsText = smsMessageText.getText().toString();

                SmsManager smsManager = SmsManager.getDefault();
                smsManager.sendTextMessage(phoneNumber, null, smsText, null, null);
            }
        }
    });

    }
}

SMSReceiver：

package pl.edu.pwr.student.a235420_ks_a5;


import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;

import android.widget.Toast;

public class SmsReceiver extends BroadcastReceiver {
    private static final String SMS_REC_ACTION =
            "android.provider.Telephony.SMS_RECEIVED";

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.i("SMS_RECIVER", "Recived Broadcast");
        if (intent.getAction().
                equals(SmsReceiver.SMS_REC_ACTION)) {

            Log.i("SMS_RECIVER", "Recived SMS");

            StringBuilder sb = new StringBuilder();
            Bundle bundle = intent.getExtras();
            if (bundle != null) {
                Object[] pdus = (Object[])
                        bundle.get("pdus");
                for (Object pdu : pdus) {
                    SmsMessage smsMessage =
                            SmsMessage.createFromPdu
                                    ((byte[]) pdu);
                    sb.append("body - " + smsMessage.
                            getDisplayMessageBody());
                }
            }
            Toast.makeText(context, "SMS RECEIVED - "
                    + sb.toString(), Toast.LENGTH_LONG).show();
        }
    }
}

我想从我的应用程序中收到的短信中获取文本，并在日志中显示或更好地在Toast中显示

接收SMS，BroadcastReceiver没有反应
