在 recyclerview 中使用 android 来控制带有 onClick 的 MediaBrowserServiceCompat

Question

我如何从我的回收站控制查看 MediaBrowserServiceCompat 中的播放和暂停状态？

Answer 1

如果 uri 与上一次点击不同，我希望它只添加一个新的 QueueItem

如果是相同的。如果它已经开始播放它应该继续播放但是如果它已经播放完并且它是相同的 uri 它应该倒带但只需点击一下

所以我这样做了

root.binding.playChat.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        //root.setIsRecyclable(false);
        root.binding.textView40.setTag(position);
        Gson gson = new GsonBuilder().create();
        ChatMessageViewModel chat = getCurrentList().get(position);
        String attachments = gson.toJson(chat.getAttachments());
        Type collectionType = new TypeToken<Collection<Attachments>>() {}.getType();
        Collection<Attachments> enums = gson.fromJson(attachments, collectionType);
        for (Attachments a : enums) {String path = a.getPath();
            try {
                currentPlay = root.binding.playChat;
                seekBar = root.binding.sb;
                textView = root.binding.textView40;
                String preUrl = "";
                String newURL = domain + path + "?apikey=" + encodeValue(apikey) + "&auth=" + auth + "&secret=" + encodeValue(secret);
                //if (preUrl.isEmpty()){
                String oldUrl = preUrl;
                if (!newURL.equals(url)) {
                    url = newURL;
                Uri myUri = Uri.parse(url);
                voicemailViewModel.addURItoQueueChat(MediaControllerCompat.getMediaController(ChatActivity.this), myUri);
                //root.binding.textView40.setText((Utils.formatLongMilliSeconds(longProgress)));
                Log.v("cptv", String.valueOf(longProgress));
                initReceiver();
                changePlayback();
                 }else {
                   MediaControllerCompat.TransportControls transportControls =  MediaControllerCompat.getMediaController(ChatActivity.this).getTransportControls();
                    int pbState = MediaControllerCompat.getMediaController(ChatActivity.this).getPlaybackState().getState();
                    if (pbState == PlaybackStateCompat.STATE_PLAYING) {changePlayback();
                    }else if (pbState == PlaybackStateCompat.STATE_PAUSED ) {changePlayback();
                    }else {
                        VoicemailPlayingService.getLiveState().observe(ChatActivity.this, new Observer<Integer>() {
                            @Override
                            public void onChanged(Integer integer) {
                                if (integer == ExoPlayer.STATE_ENDED){
                                    MediaControllerCompat.getMediaController(ChatActivity.this).getTransportControls().seekTo(0);
                                    MediaControllerCompat.getMediaController(ChatActivity.this).getTransportControls().pause();
                                    currentPlay.setImageResource(R.drawable.ic_outline_play_arrow_24);}

                            }
                        });
                    }
                }
            } catch (Exception e) {}
        }
    }

changePlayback() 是这样的

void changePlayback() {
    int pbState = MediaControllerCompat.getMediaController(ChatActivity.this).getPlaybackState().getState();
    if (pbState == PlaybackStateCompat.STATE_PLAYING) {
        MediaControllerCompat.getMediaController(this).getTransportControls().pause();
        currentPlay.setImageResource(R.drawable.ic_outline_play_arrow_24);
    } else if (pbState == PlaybackStateCompat.STATE_PAUSED || pbState ==0 ){
        MediaControllerCompat.getMediaController(this).getTransportControls().play();
        currentPlay.setImageResource(R.drawable.ic_baseline_pause_24);}
}
