Media Player контролирует уведомление
Я написал полный музыкальный проигрыватель для потоковой передачи музыки из Интернета, но я не знаю, как установить элементы управления медиаплеером в Notification и когда на экране заблокирован.
Я следую за этот учебник, чтобы отображать элементы управления на панели уведомлений, но все еще не получая. Как использовать те же функции в моей программе, я импортировали необходимые классы, такие как: NotificationService.java
и Constants.java
.
Это то, что я получаю в панели уведомлений:
[
]
Я смущен. Почему я не получаю название песни, которую я играю, почему пауза, предыдущие и следующие кнопки не работают и т.д....

Привет, Софи, код ниже поможет вам.
Вызовите этот метод в своем MainActivity
public void showNotification(View view){
new MyNotification(this);
finish();
}
Создать новый пользовательский класс уведомлений
public class MyNotification extends Notification {
private Context ctx;
private NotificationManager mNotificationManager;
@SuppressLint("NewApi")
public MyNotification(Context ctx){
super();
this.ctx=ctx;
String ns = Context.NOTIFICATION_SERVICE;
mNotificationManager = (NotificationManager) ctx.getSystemService(ns);
CharSequence tickerText = "Shortcuts";
long when = System.currentTimeMillis();
Notification.Builder builder = new Notification.Builder(ctx);
@SuppressWarnings("deprecation")
Notification notification=builder.getNotification();
notification.when=when;
notification.tickerText=tickerText;
notification.icon=R.drawable.ic_launcher;
RemoteViews contentView=new RemoteViews(ctx.getPackageName(), R.layout.messageview);
//set the button listeners
setListeners(contentView);
notification.contentView = contentView;
notification.flags |= Notification.FLAG_ONGOING_EVENT;
CharSequence contentTitle = "From Shortcuts";
mNotificationManager.notify(548853, notification);
}
public void setListeners(RemoteViews view){
//radio listener
Intent radio=new Intent(ctx,HelperActivity.class);
radio.putExtra("DO", "radio");
PendingIntent pRadio = PendingIntent.getActivity(ctx, 0, radio, 0);
view.setOnClickPendingIntent(R.id.radio, pRadio);
//volume listener
Intent volume=new Intent(ctx, HelperActivity.class);
volume.putExtra("DO", "volume");
PendingIntent pVolume = PendingIntent.getActivity(ctx, 1, volume, 0);
view.setOnClickPendingIntent(R.id.volume, pVolume);
//reboot listener
Intent reboot=new Intent(ctx, HelperActivity.class);
reboot.putExtra("DO", "reboot");
PendingIntent pReboot = PendingIntent.getActivity(ctx, 5, reboot, 0);
view.setOnClickPendingIntent(R.id.reboot, pReboot);
//top listener
Intent top=new Intent(ctx, HelperActivity.class);
top.putExtra("DO", "top");
PendingIntent pTop = PendingIntent.getActivity(ctx, 3, top, 0);
view.setOnClickPendingIntent(R.id.top, pTop);*/
//app listener
Intent app=new Intent(ctx, com.example.demo.HelperActivity.class);
app.putExtra("DO", "app");
PendingIntent pApp = PendingIntent.getActivity(ctx, 4, app, 0);
view.setOnClickPendingIntent(R.id.btn1, pApp);
}
}
Создать класс HelperActivity
public class HelperActivity extends Activity {
private HelperActivity ctx;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
ctx = this;
String action = (String) getIntent().getExtras().get("DO");
if (action.equals("radio")) {
//Your code
} else if (action.equals("volume")) {
//Your code
} else if (action.equals("reboot")) {
//Your code
} else if (action.equals("top")) {
//Your code
} else if (action.equals("app")) {
//Your code
}
if (!action.equals("reboot"))
finish();
}
@Override
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
}
}
И XML-макет для уведомления здесь
<TextView
android:id="@+id/msglbl"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

Ответ 2
попробуйте что-то вроде этого (я использовал целые числа для действий):
intent.putExtra("action", ACTION_EXIT);
pendingIntent = PendingIntent.getService(this, intent.getIntExtra("action", 0), intent, PendingIntent.FLAG_UPDATE_CURRENT);
в общедоступном статическом PendingIntent getService (контекст контекста, int requestCode, намерение Intent, int flags)
requestCode должен быть уникальным.
Ответ 3
Вам нужно установить действие пользовательского намерения, а не класс компонента AudioPlayerBroadcastReceiver.
Создайте намерение с пользовательским именем действия, подобным этому
Intent switchIntent = new Intent("com.example.app.ACTION_PLAY");
Then, register the PendingIntent Broadcast receiver
PendingIntent pendingSwitchIntent = PendingIntent.getBroadcast(this, 100, switchIntent, 0);
Then, set a onClick for the play control , do similar custom action for other controls if required.
notificationView.setOnClickPendingIntent(R.id.btn_play_pause_in_notification, pendingSwitchIntent);
Затем зарегистрируйте пользовательское действие в AudioPlayerBroadcastReceiver, как это
<receiver android:name="com.example.app.AudioPlayerBroadcastReceiver" >
<intent-filter>
<action android:name="com.example.app.ACTION_PLAY" />
</intent-filter>
</receiver>
Наконец, при нажатии на макет Notification RemoteViews, вы получите действие воспроизведения с помощью BroadcastReceiver
public class AudioPlayerBroadcastReceiver extends BroadcastReceiver{
@Override
public void onReceive (контекстный контекст, намерение намерения) {
String action = intent.getAction();
if(action.equalsIgnoreCase("com.example.app.ACTION_PLAY")){
// do your stuff to play action;
}
}
}
EDIT: как установить фильтр намерений для широковещательного приемника, зарегистрированного в коде
Вы также можете настроить фильтр Custom Action to Intent из кода для зарегистрированного широковещательного приемника, такого как
// instance of custom broadcast receiver
CustomReceiver broadcastReceiver = new CustomReceiver();
IntentFilter intentFilter = new IntentFilter();
intentFilter.addCategory(Intent.CATEGORY_DEFAULT);
// set the custom action
intentFilter.addAction("com.example.app.ACTION_PLAY");
// register the receiver
registerReceiver(broadcastReceiver, intentFilter);

Вы нашли решение? Я могу объяснить вам код antoher, его немного то же самое, но я уже изменил для меня, потому что я играю Streaming Audio. Дайте мне знать, если вам нужна помощь.
Просто хочу поделиться с вами, как использовать метод showNotification()
private void showNotification() {
if (intent.getAction().equals(Constants.ACTION.STARTFOREGROUND_ACTION)) {
//Start IntentNotification
Log.i(LOG_TAG, "Received Start Foreground Intent ");
Intent notificationIntent = new Intent(ForegroundService.this, MainActivity.class);
notificationIntent.setAction(Constants.ACTION.MAIN_ACTION);
//With this settings you can open the same Activity without recreate.
//But you have to put in your AndroidManifest.xml the next line: to your Activity
//activity android:name=".MainActivity" android:launchMode="singleInstance"
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,
notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
//Intent for Play
Intent playIntent = new Intent(this, ForegroundService.class);
playIntent.setAction(Constants.ACTION.PLAY_ACTION);
PendingIntent pplayIntent = PendingIntent.getService(this, 0,
playIntent,0);
//Intent for Pause
Intent pausaIntent = new Intent(this, ForegroundService.class);
pausaIntent.setAction(Constants.ACTION.PAUSE_ACTION);
PendingIntent pauseIntent = PendingIntent.getService(this, 0,
pausaIntent, 0);
//Intent for Close
stopIntent = new Intent(this, ForegroundService.class);
stopIntent.setAction(Constants.ACTION.CLOSE_ACTION);
PendingIntent closeIntent = PendingIntent.getService(this, 0,
stopIntent, 0);
//Icon for your notification
Bitmap icon = BitmapFactory.decodeResource(getResources(),
R.mipmap.ic_launcher);
notifManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
PendingIntent pi = PendingIntent.getActivity(getApplicationContext(), 0,
new Intent(getApplicationContext(), MainActivity.class),
PendingIntent.FLAG_UPDATE_CURRENT);
// Build the notification object.
mNotificationBuilder = new Notification.Builder(this)
.setContentTitle("Thinking out Loud")
.setContentText("Ed Sheeran")
.setSmallIcon(R.mipmap.ic_launcher)
.setLargeIcon(
Bitmap.createScaledBitmap(icon, 128, 128, false))
.setContentIntent(pendingIntent)
.setOngoing(true)
.addAction(R.drawable.ic_play_service, "PLAY", //you can set a specific icon
pplayIntent)
.addAction(R.drawable.ic_pause_service, "PAUSE",//you can set a specific icon
pauseIntent)
.addAction(R.drawable.ic_close_service, "CLOSE", closeIntent);//you can set a specific icon
startForeground(Constants.NOTIFICATION_ID.FOREGROUND_SERVICE, mNotificationBuilder.build());
} else if (intent.getAction().equals(Constants.ACTION.PLAY_ACTION)) {
Log.i(LOG_TAG, "Clicked Play");
//Click Play notification
} else if (intent.getAction().equals(Constants.ACTION.PAUSE_ACTION)) {
Log.i(LOG_TAG, "Clicked PAUSE");
//This is for Pause
} else if (intent.getAction().equals(Constants.ACTION.CLOSE_ACTION)) {
Log.i(LOG_TAG, "Clicked Close");
//This is for close the NotificationService
stopForeground(true);
} else if (intent.getAction().equals(
Constants.ACTION.STOPFOREGROUND_ACTION)) {
Log.i(LOG_TAG, "Received Stop Foreground Intent");
stopForeground(true);
//Stop Notification Service
stopSelf();
}
}
