Question

我是android编程的新手。我的应用程序通知有问题，重启后它会消失！

我的应用程序是关于自动转发短信，它也可以通过短信启用。我希望在启用应用程序时显示通知。我对通知有2个问题：

1.重启后通知消失了！

2.通过短信启用应用程序时，不会显示通知！

这是我的代码：

SmsForwardConfig.java

public class SmsForwarderConfig extends Activity {
public static final String KEY_IS_ENABLED = "SmsForwarderConfig_enabled";
public static final String KEY_IS_AUTO = "SmsForwarderConfig_auto";
public static final String KEY_SMS_NO = "SmsForwarderConfig_number";
public static final String APP_SET_NAME = "SmsForwarderConfig_g_cfg";
public static final String PASSWORD = "SmsForwarderConfig_pass";


@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);


final SharedPreferences mSettings = getSharedPreferences(APP_SET_NAME, MODE_PRIVATE);
final Button ok = (Button) findViewById(R.id.ok);
final TextView mTxtForwardTo = (TextView) findViewById(R.id.editText1);
final TextView password = (TextView) findViewById(R.id.editText2);
final TextView tx1 = (TextView) findViewById(R.id.textView1);
final TextView tx2 = (TextView) findViewById(R.id.textView2);
final TextView tx3 = (TextView) findViewById(R.id.textView3);
final TextView tx4 = (TextView) findViewById(R.id.textView4);
final CheckBox chk = (CheckBox) findViewById(R.id.checkBox1);
final CheckBox chk2 = (CheckBox) findViewById(R.id.checkBox2);
final ImageButton imgr = (ImageButton) findViewById(R.id.imgbtnr);
final ImageButton support = (ImageButton) findViewById(R.id.support);

Typeface font = Typeface.createFromAsset(getAssets(), "font.ttf");  
ok.setTypeface(font);
mTxtForwardTo.setTypeface(font);
password.setTypeface(font);
tx1.setTypeface(font);
tx2.setTypeface(font);
tx3.setTypeface(font);
tx4.setTypeface(font);

final NotificationManager nm = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
final Notification notify = new Notification(R.drawable.ic_launcher, "sms divert is enabled!", System.currentTimeMillis());
Context context = SmsForwarderConfig.this;
CharSequence title = "sms divert!";
CharSequence details = "sms divert is enabled!";
Intent intent = new Intent (context, SmsForwarderConfig.class);
PendingIntent pending = PendingIntent.getActivity(context, 0, intent, 0);
notify.setLatestEventInfo(context, title, details, pending);
notify.flags = Notification.FLAG_ONGOING_EVENT;



//set pre entered values
if (mSettings.getBoolean(KEY_IS_ENABLED, false)) {

    chk.setChecked(true);


} else {

    chk.setChecked(false);
}

if (mSettings.getBoolean(KEY_IS_AUTO, false)) {
    chk2.setChecked(true);
} else {
    chk2.setChecked(false);
}
mTxtForwardTo.setText(mSettings.getString(KEY_SMS_NO, ""));
password.setText(mSettings.getString(PASSWORD, ""));

//prepare listener
ok.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {

        final String telNumber = mTxtForwardTo.getText().toString();
        final boolean isEnabled = chk.isChecked();
        final boolean remoteControl = chk2.isChecked();

        if (chk.isChecked()) {
            nm.notify(0, notify);
        } else {
            nm.cancel(0);
        }

        SharedPreferences.Editor editor = mSettings.edit();
        editor.putBoolean(KEY_IS_ENABLED, isEnabled);
        editor.putString(KEY_SMS_NO, telNumber);
        editor.putBoolean(KEY_IS_AUTO, remoteControl);
        editor.putString(PASSWORD, password.getText().toString());
        editor.commit();

    }
});

    imgr.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View arg0) {
        Intent link = new Intent(Intent.ACTION_VIEW);
        link.setData(Uri.parse("bazaar://search?q=Ratin&c=apps"));
        startActivity(link);
    }
});

    support.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            startActivity(new Intent(SmsForwarderConfig.this, SupportActivity.class));

        }
    });

}

和SmsReceiver.java

public class SmsReceiver extends BroadcastReceiver {


@Override
public void onReceive(Context context, Intent intent) {

final SharedPreferences settings = context.getSharedPreferences(SmsForwarderConfig.APP_SET_NAME, Context.MODE_PRIVATE);
boolean isActive = settings.getBoolean(SmsForwarderConfig.KEY_IS_ENABLED, false);
final boolean isRemoteEnabled = settings.getBoolean(SmsForwarderConfig.KEY_IS_AUTO, false);
final String telNumber = settings.getString(SmsForwarderConfig.KEY_SMS_NO, "");

searchRemoteReq:
if (isRemoteEnabled && !isActive) {
    String password = settings.getString(SmsForwarderConfig.PASSWORD, "");
    if (password.trim().length() > 0) {
        Bundle bundle = intent.getExtras();
        SmsMessage[] msgs = null;
        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]);
                String message = msgs[i].getMessageBody().toString();
                if (message.contains(password)) {
                    isActive = true;
                    SharedPreferences.Editor editor = settings.edit();
                    editor.putBoolean(SmsForwarderConfig.KEY_IS_ENABLED, true);
                    editor.commit();
                    break searchRemoteReq;
                }
            }
        }

    }
}

if (isActive && telNumber != null && telNumber.length() > 0) {
    Log.v("SmsReceiver", "Is active: " + isActive);
    Log.v("SmsReceiver", "Tel Number: " + telNumber);
    sendSMS(context, intent, telNumber);
}
}

private void sendSMS(Context context, Intent intent, String phoneNumber) {
//---get the SMS message passed in---
Bundle bundle = intent.getExtras();
SmsMessage[] msgs = null;
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]);
        SmsManager sms = SmsManager.getDefault();
        String from = msgs[i].getDisplayOriginatingAddress();
        String message = msgs[i].getMessageBody().toString();
        String all = from + ":" + message;
        Log.v("SmsReceiver", "SMS Message: " + all);
        sms.sendTextMessage(phoneNumber, null, all, null, null);
    }

}
}
}

您需要创建一个后台作业（一个Android服务），它将在重新启动后运行并查找已保存的通知并显示它们。您的应用程序在重新启动后被终止，因此Android无法与其通信并显示通知

重启后android通知消失
