Android 通知 bigcontentview : different layout on expand and collepse

Question

我在通知 bigcontentview 的展开和折叠方面遇到了一些问题。

当通知在通知列表的顶部时，有android文档中所述的扩展 View ，但是当通知不在通知列表的顶部时，通知 View 变得奇怪。我给你看图

(抱歉隐藏了图片中的内容)

(1.折叠 View )

在此通知内容变得不可见

(2.展开图)

展开所有可见内容后，我知道这是正确的行为。

但我想在通知折叠时更改布局。这样我就可以更改布局并且内容可见

有解决办法吗？我如何获得折叠或展开的通知？ 以及如何在展开和折叠期间更改它的布局？所以所有内容都可见。

有什么方法可以为展开和折叠的通知添加不同的布局？

我的代码如下:

@SuppressLint("NewApi")
    public void updateNotification(String text) {

        PendingIntent pendingIntent = null;
        PendingIntent pendingIntent1 = null;
        PendingIntent pendingIntent2 = null;
        PendingIntent pendingIntent3 = null;
        PendingIntent pendingIntent4 = null;
        PendingIntent pendingIntent5 = null;

        if (mRemoteViews == null) {
            Log.d("LOG", "mRemoteViews is null");
            if (Base.sharedPref.getBoolean("firsttimenotifiation", false)) {

                mRemoteViews = new RemoteViews(getPackageName(),
                        R.layout.custom_notification);
            } else {
                if (isCurrentBuildabove16()) {
                    mRemoteViews = new RemoteViews(getPackageName(),
                            R.layout.customizenotification);
                } else {
                    mRemoteViews = new RemoteViews(getPackageName(),
                            R.layout.customnotification);
                }
            }
        } else {
            if (MusicList.MusicFrom != MusicList.FromNotification) {
            if (mState == State.Paused || mState == State.Stopped || mState == State.Stopappnotification) {


                try {
                    Log.e("LOG", "State.Paused || State.Stopped");
                    mRemoteViews.setImageViewResource(R.id.playpush,
                            R.drawable.playdetailfornoti);

                }catch (Exception e) {}
            } else if (mState == State.Playing) {
                try {
                    Log.e("LOG", "State.Playing");
                    mRemoteViews.setImageViewResource(R.id.playpush,
                            R.drawable.pushdetail);

                } catch (Exception e) {

                }
            } else if (mState == State.Retrieving) {
                try {

                    mRemoteViews.setImageViewResource(R.id.playpush,
                            R.drawable.playdetailfornoti);

                } catch (Exception e) {
                }
            } else {
                try {
                        mRemoteViews.setImageViewResource(R.id.playpush,
                                R.drawable.pushdetail);
                } catch (Exception e) {
                }
            }
        }
        }

        Intent intent = new Intent(ACTION_TOGGLE_PLAYBACK);

        mRemoteViews.setOnClickPendingIntent(R.id.playernewspapaer,

        mRemoteViews.setOnClickPendingIntent(R.id.playerimage, contentIntent);

        mRemoteViews.setOnClickPendingIntent(R.id.playpush, pendingIntent);

        mRemoteViews.setOnClickPendingIntent(R.id.close, pendingIntent1);

    // coded differently for those below 16(which is not supported bigview) and above 16 api level

    }

请帮助我提前致谢

我同时设置了通知的大 View 和普通 View ，它允许通过展开和折叠在两者之间切换。

但是大 View 还有另一个问题:如果我设置了大 View ，每次更新通知时它都会闪烁..
