我想从我的 Activity 中启动 ProgressDialog 和 Broadcast Receiver (SMS_RECEIVED)。当从定义的号码收到短信时，它应该停止对话并分析短信文本。
此刻我有 Dialog 和 Receiver，两者都有效。当我关闭对话框时，它会停止 Receiver。
但是，当接收到 SMS 并将 SMS 文本提供给 Activity 时，我怎样才能让它工作，关闭对话框？
我的 Activity 中的 ProgressDialog:
protected void sendSMS(String sms){
try {
final ComponentName receiver = new ComponentName(this, IncomingSms.class);
final PackageManager pm = this.getPackageManager();
pm.setComponentEnabledSetting(receiver,PackageManager.COMPONENT_ENABLED_STATE_ENABLED,PackageManager.DONT_KILL_APP);
waitSms = new ProgressDialog(this);
waitSms.setTitle("Warte auf Bestätigungs SMS");
waitSms.setCancelable(false);
waitSms.setMessage("Abbrechen setzt die Einstellung in der App auf inaktiv zurück. Nicht warten übernimmt die Einstellung in der App, wartet aber nicht weiter auf eine Bestätigungs SMS.");
waitSms.setButton(DialogInterface.BUTTON_NEGATIVE, "Abbrechen", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
pm.setComponentEnabledSetting(receiver, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
waitSms.dismiss();
}
});
waitSms.setButton(DialogInterface.BUTTON_POSITIVE, "Nicht warten", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
pm.setComponentEnabledSetting(receiver, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
waitSms.dismiss();
}
});
waitSms.show();
}
我的广播接收器:
public class IncomingSms extends BroadcastReceiver {
// Get the object of SmsManager
final SmsManager sms = SmsManager.getDefault();
public void onReceive(Context context, Intent intent) {
// Retrieves a map of extended data from the intent.
final Bundle bundle = intent.getExtras();
try {
if (bundle != null) {
final Object[] pdusObj = (Object[]) bundle.get("pdus");
for (int i = 0; i < pdusObj.length; i++) {
SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
String phoneNumber = currentMessage.getDisplayOriginatingAddress();
String senderNum = phoneNumber;
String message = currentMessage.getDisplayMessageBody();
Log.i("SmsReceiver", "senderNum: "+ senderNum + "; message: " + message);
int duration = Toast.LENGTH_LONG;
Toast toast = Toast.makeText(context, "senderNum: "+ senderNum + ", message: " + message, duration);
toast.show();
} // end for loop
} // bundle is null
} catch (Exception e) {
Log.e("SmsReceiver", "Exception smsReceiver" +e);
}
}
}
谢谢帮助
最佳答案
你用你的标志禁用了接收器:
PackageManager.COMPONENT_ENABLED_STATE_DISABLED.
试试这个:
PackageManager.COMPONENT_ENABLED_STATE_ENABLED
然后在您的 Receiver onReceive 中，将数据移动到具有 Intent extras 的 Activity，并使用 onNewIntent() 拦截它们。
发送数据后，您可以根据需要禁用接收器。
