Android 如何在用户按下通知后播放音频文件?
我正试图通过一个应用程序从互联网上下载一首歌曲。我将其编码为在下载完成时显示通知,但问题是单击通知时我不知道该怎么办。我希望它在单击通知时播放歌曲Android 如何在用户按下通知后播放音频文件?,android,android-intent,android-notifications,Android,Android Intent,Android Notifications,我正试图通过一个应用程序从互联网上下载一首歌曲。我将其编码为在下载完成时显示通知,但问题是单击通知时我不知道该怎么办。我希望它在单击通知时播放歌曲 String ns = Context.NOTIFICATION_SERVICE; NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns); int icon = R.drawable.m;
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);
int icon = R.drawable.m; // icon from resources
CharSequence tickerText = "Song Downloaded"; // ticker-text
long when = System.currentTimeMillis(); // notification time
Context context = getApplicationContext(); // application Context
CharSequence contentTitle = name; // expanded message title
CharSequence contentText = "Your song "+name +" has been Song Downloaded"; // expanded message text
Intent notificationIntent = new Intent(this, notif.class);
notificationIntent.putExtra("song", name);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
// the next two lines initialize the Notification, using the configurations above
Notification notification = new Notification(icon, tickerText, when);
notification.sound = Uri.withAppendedPath(Audio.Media.INTERNAL_CONTENT_URI, "6");
notification.flags = Notification.DEFAULT_LIGHTS & Notification.FLAG_AUTO_CANCEL;
notification.ledARGB = 0xff0000ff;
notification.ledOnMS = 500;
notification.ledOffMS = 3000;
notification.defaults |= Notification.DEFAULT_LIGHTS;
notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
final int HELLO_ID = 1;
mNotificationManager.notify(HELLO_ID, notification);
这清楚地表明意图从notif.class开始,但我不知道在notif.class中该做什么我尝试了这个,但当我点击notif时,它仍然没有显示任何内容
class notif extends Activity
{
MediaPlayer abc=new MediaPlayer();
public void onCreate(Bundle icicle){
File SDCardRoot = Environment.getExternalStorageDirectory();
Intent intent = getIntent();
Bundle bundle = intent.getExtras();
String name = bundle.getString("song");
try {
abc.setDataSource(SDCardRoot.getAbsolutePath() + "/Music/"+name+".mp3");
abc.prepare();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
if(name!="")
{ abc.start(); }
}
}
试试这个:
@Override
public void onNewIntent(Intent intent) {
Bundle extras = intent.getExtras();
if (extras!=null) {
...
}
}
