我正在使用清单中定义的接收器类，例如

    <receiver 
      android:name="com.escortme.basic.SMSReceiverActivity"
      android:enabled="true">
      <intent-filter>
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
      </intent-filter>
    </receiver>

收听传入的文本，但问题是如何从 SMSReceiverActivity 中的 onrecieve 方法调用手机正在显示的当前活动的方法？

因此，例如，如果我当前在手机上使用 pol_viewactivity，那么我收到一条文本，我知道 onrecieve 方法是在 SMSReceiverActivity 的后台发生的，但是在 onreceive 方法中，我如何从 pol_viewactivity 中调用一个方法？

试试这个希望对你有帮助

public class SMS extends Activity 
{

    Button btnSendSMS;
    EditText txtPhoneNo;
    EditText txtMessage;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);        
        btnSendSMS = (Button) findViewById(R.id.btnSendSMS);
        txtPhoneNo = (EditText) findViewById(R.id.txtPhoneNo);
        txtMessage = (EditText) findViewById(R.id.txtMessage);

        /*
        Intent sendIntent = new Intent(Intent.ACTION_VIEW);
        sendIntent.putExtra("sms_body", "Content of the SMS goes here..."); 
        sendIntent.setType("vnd.android-dir/mms-sms");
        startActivity(sendIntent);
        */

        btnSendSMS.setOnClickListener(new View.OnClickListener() 
        {
            public void onClick(View v) 
            {

                String message = txtMessage.getText().toString();               
                if (phoneNo.length()>0 && message.length()>0)

那么你应该要么

1）把你的onReceive方法放在你的pol_viewactivity；或者，

2) 提供一个监听器SMSReceiverActivity并由 设置pol_viewactivity。

编辑：

响应如何创建监听器。

在你的SMSReceiverActivity，定义一个接口，

public interface ExampleListener {
    onMsgReceive(String msg);
}

声明监听器和公共方法，

private ExampleListener listener;

public void setExampleListener(ExampleListener listener) {
    this.listener = listener;
}

在 的onReceive方法中BroadcastReceiver，

if (listener != null) {
    listener.onMsgReceive("Your message to pass");
}

在你的pol_viewactivity，想办法设置监听器的方式类似于调用的方式setOnClickListener()。如果您无法检索 的实例SMSReceiverActivity以设置侦听器，则将侦听器设为静态。我知道这不是一个很好的方式，但在你的情况下，如果你不能改变设计，这种方式应该会有所帮助。（也许您可以将 BroadcastReceiver 隔离到一个类中并在那里进行所有处理。）
