Android：从具有remoteview的多个通知更新特定通知
[英]Android: update specific notification from multiple notifications which have remoteview
问题描述
我正在创建包含播放/暂停图标的通知的应用程序。 当只有一个通知只有一个通知ID时它完美地工作，它只通过一个notificationid改变播放/暂停图标，但是存在多个通知的问题。 当有多个通知时，每个通知都有播放/暂停图标。 当我从其中一个通知中单击播放/暂停图标时，它只会从通知堆栈中更改顶部通知图标。 我知道这个问题是由于它点击任何通知所得到的通知ID。我想获得点击播放/暂停图标的所有通知的ID。我尝试了一些pendingIntent内容的更改，但还没有找到确切的解决方案。
我想知道， 有没有办法获得通知的通知，点击该播放/暂停图标？ ，所以我可以通过通知ID更改图标或更新该通知。需要通过通知ID更新通知。
我已经使用远程视图来获取通知中的服装布局。 代码如下
NotificationCode
RemoteViews mRemoteViews1 = null;
PendingIntent pendingIntent = null;
PendingIntent pendingIntent1 = null;
PendingIntent pendingIntent2 = null;
PendingIntent pendingIntent3 = null;
PendingIntent pendingIntent4 = null;
PendingIntent pendingIntent5 = null;
if (mRemoteViews1 == null) {
Log.d("LOG", "mRemoteViews is null");
mRemoteViews1 = new RemoteViews(getPackageName(),
R.layout.custom_notification);
} else {
if (mState == palyer.Paused || mState == palyer.Stopped) {
try {
Log.e("LOG", "State.Paused || State.Stopped");
mRemoteViews1.setImageViewResource(R.id.playpush,
R.drawable.playdetailfornoti); // play icon
} catch (Exception e) {}
} else if (mState == palyer.Playing) {
try {
Log.e("LOG", "State.Playing");
mRemoteViews1.setImageViewResource(R.id.playpush,
R.drawable.pushdetail); // pushicon
} catch (Exception e) {}
} else if (mState == palyer.Retrieving) {
try {
Log.e("LOG", "else Retrieving");
mRemoteViews1.setImageViewResource(R.id.playpush,

}
else {
try {
Log.e("LOG", "else");
mRemoteViews1.setImageViewResource(R.id.playpush,

}
}

我只想在您放入PendingIntent的意图中添加一个ID，以了解您正在操作的通知，如下所示：
Intent intent = new Intent（ACTION_TOGGLE_PLAYBACK）;
intent.putExtra（EXTRA_ID，songID）;
您可以稍后在调用的代码中提取此额外内容：
字符串songID = intent.getStringExtra（EXTRA_ID）;

经过大量尝试后，我通过更改待处理意图中的一些代码来找出解决方案，如下面的代码所示
我的代码如下
public void UpdateNotificationfunction(int currentNotificationNo) {
RemoteViews mRemoteViews1 = null;
PendingIntent pendingIntent = null;
PendingIntent pendingIntent1 = null;
PendingIntent pendingIntent2 = null;
PendingIntent pendingIntent3 = null;
PendingIntent pendingIntent4 = null;
PendingIntent pendingIntent5 = null;
if (mRemoteViews1 == null) {
Log.d("LOG", "mRemoteViews is null");
mRemoteViews1 = new RemoteViews(getPackageName(),
R.layout.custom_notification);
} else {
if (mState == palyer.Paused || mState == palyer.Stopped) {
try {
Log.e("LOG", "State.Paused || State.Stopped");
mRemoteViews1.setImageViewResource(R.id.playpush,
R.drawable.playdetailfornoti); // play icon
} catch (Exception e) {}
} else if (mState == palyer.Playing) {
try {
Log.e("LOG", "State.Playing");
mRemoteViews1.setImageViewResource(R.id.playpush,
R.drawable.pushdetail); // pushicon
} catch (Exception e) {}
} else if (mState == palyer.Retrieving) {
try {
Log.e("LOG", "else Retrieving");
mRemoteViews1.setImageViewResource(R.id.playpush,
R.drawable.playdetailfornoti); // play icon
} catch (Exception e) {}
}
else {
try {
Log.e("LOG", "else");
mRemoteViews1.setImageViewResource(R.id.playpush,
R.drawable.pushdetail); // pushicon
