而不是由BroadcastReceiver的收

而不是由BroadcastReceiver的收

本文介绍了Android的PendingIntent演员,而不是由BroadcastReceiver的收的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

当我路过群众演员到一个PendingIntent,永远不会被sendBroadcastReceiver收到的消息,因为这确实是的onReceive()方法的BroadcastReceiver 永远不会被调用。为什么会出现这种情况?

解决方案

我想有与注册和注销的code的一些问题。相反,我注册了两个 BroadcastReceivers 的Andr​​oidManifest.xml 文件,并能顺利通过临时演员。

When I pass extras to a PendingIntent, the message is never received by the sendBroadcastReceiver, because the onReceive() method of this BroadcastReceiver is never called. Why is this happening?

public class MainActivity extends Activity {
    private static String SENT = "SMS_SENT";
    private static String DELIVERED = "SMS_DELIVERED";
    private static int MAX_SMS_MESSAGE_LENGTH = 160;

    private static Context mContext;
    private BroadcastReceiver sendBroadcastReceiver, deliveryBroadcastReceiver;
    private final String DEBUG_TAG = getClass().getSimpleName().toString();

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // ---when the SMS has been sent---
        sendBroadcastReceiver = new BroadcastReceiver() {

            public void onReceive(Context arg0, Intent arg1) {
                switch (getResultCode()) {
                    case Activity.RESULT_OK:
                        Toast.makeText(getBaseContext(), "SMS Sent", Toast.LENGTH_SHORT).show();
                        break;
                    case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                        Toast.makeText(getBaseContext(), "Generic failure", Toast.LENGTH_SHORT).show();
                        break;

解决方案

I guess there are some issues with registering and unregistering in the code. Instead I registered the two BroadcastReceivers in the AndroidManifest.xml file and was able to successfully pass extras.
