通知用のこのコードは機能しますが、通知をクリックするたびにアプリケーションフォースが閉じます。理由はわかりません。通知をクリックするとキャンセルされるようにしたいのですが、可能であればタイミングを合わせたいのですが、手伝ってもらえますか？
コードは次のとおりです。
package egypt.interfaceAct;
import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Bundle;
import android.widget.Toast;
public class Notifications extends Activity {
NotificationManager nm;
int uniqueID = 13393;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
Bundle programNum = getIntent().getExtras();
final String body = programNum.getString("Activity");
final String startTime = programNum.getString("Start");
final String endTime = programNum.getString("End");
nm = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
nm.cancel(uniqueID);
String notify = body + "Start at: " + startTime + " to: " + endTime;
Intent intent = new Intent(this,ProgramsList2.class);
PendingIntent pi = PendingIntent.getActivity(this, 1, intent, 0);
//String body = (String) ((TextView)parent.getChildAt(position)).getText();
String title = "Egypt On The Go";
//String time = body + "\n start at:" + startTime+ "\n end at:" + endTime.get(position);
Notification n = new Notification(R.drawable.egypt, notify, System.currentTimeMillis());
n.setLatestEventInfo(this, title, notify, pi);
n.defaults = Notification.DEFAULT_ALL;
nm.notify(uniqueID, n);
n.flags = Notification.FLAG_AUTO_CANCEL;
//Intent i = new Intent(this, ProgramsList2.class);
//startActivity(i);
finish();
}
}
これがlogCatです。多分それは役立つでしょう：
