我正在使用 RemoteInput 创建一个通知，以从通知本身中捕获文本。
当我使用RemoteInput.getResultsFromIntent()在被调用服务中检索 RemoteInput 时，它返回 null 的问题。我已验证代码如 google api 中所示。会发生什么？
活动：
Intent intentMenu = new Intent(getApplicationContext(), NotificationToolsService.class);
intentMenu.setAction("personalACTION");
RemoteInput remoteInput = new RemoteInput.Builder(FV.REMOTE_INPUT_KEY)
.setLabel("Message...").build();
PendingIntent pIntentMenu = PendingIntent.getService(getApplicationContext(),20,intentMenu,PendingIntent.FLAG_IMMUTABLE);
NotificationCompat.Action remoteInputAction = new NotificationCompat.Action.Builder(0,"Reply",pIntentMenu)
.addRemoteInput(remoteInput)
.build();
Notification notificationRemoteInput = new NotificationCompat.Builder(getApplicationContext(),FV.CHANNEL_TEST)
.setSmallIcon(R.drawable.linterna)
.setContentTitle("Conversation with Javier")
.setContentText("Javier: Hi! How are you?")
.addAction(remoteInputAction)
.setLargeIcon(BitmapFactory.decodeResource(getResources(),R.drawable.foto1)).build();
notificationManagerCompat.notify(FV.NOTIFICATION_CONVERSATION,notificationRemoteInput);
服务：
public int onStartCommand(Intent intent, int flags, int startId) {
if(intent.getAction() == "personalACTION") {
Bundle keys = RemoteInput.getResultsFromIntent(intent);
CharSequence text = keys.getCharSequence(FV.REMOTE_INPUT_KEY);
Toast.makeText(this, "Reply with"+text, Toast.LENGTH_SHORT).show();
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
Notification notificationRemoteInput = new NotificationCompat.Builder(this,FV.CHANNEL_TEST)
.setSmallIcon(R.drawable.linterna)
.setContentTitle("Conversation with Javier")
.setContentText("Javier: Hi! How are you? \n Me:"+text)
.setAutoCancel(true)
.setLargeIcon(BitmapFactory.decodeResource(getResources(),R.drawable.foto1)).build();
notificationManager.notify(FV.NOTIFICATION_CONVERSATION,notificationRemoteInput);
}
return super.onStartCommand(intent, flags, startId);
}
