android - 如何从通知中打开当前 fragment ？

Question

我制作了一个包含故事的应用程序，其中一些包含文字和音频。ol 导航我在 fragment 中制作，所以首先 - 带有 listView 和 taleNames 的 fragment ，当一些选择时 - 下一个 fragment ，我将在其中上传所选故事的文本和音频。对于音频，我正在使用服务，当 audioTales 启动时，我也会在那里推送通知。

我的下一个问题是:当我启动服务并开始播放音频时，我从我的应用程序隐藏到主屏幕，而不是单击工具栏中的通知。我需要通知将我推送到正在播放音频 Tale 的当前 fragment ，但实际上它将我推送到 ListView。

这是我的通知:

    private void initNotification(){
            CharSequence tikerText = getResources().getString(R.string.tickerText);
            NotificationManager mNotificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
            Notification notification = new Notification(R.drawable.ic_launcher,tikerText,System.currentTimeMillis());
            notification.flags = Notification.FLAG_ONGOING_EVENT;
            Context context = getApplicationContext();
            CharSequence contentTitle = getResources().getString(R.string.contentTitle);
            CharSequence contentText = getResources().getString(R.string.contentText);
            Intent notifIntent = context.getPackageManager().getLaunchIntentForPackage(context.getPackageName());
            notifIntent.putExtra("showAudioFrag",true);
            PendingIntent contentIntent = PendingIntent.getActivity(context,0,notifIntent,0);
            notification.setLatestEventInfo(context,contentTitle,contentText,contentIntent);
            mNotificationManager.notify(NOTIFICATION_ID,notification);
        }

我在 OnCreate 的 MainActivity 中添加的下一个代码:

intent = getIntent();
        boolean reloadFragmentFromNotification = intent.getBooleanExtra("showAudioFrag",false);
        if (reloadFragmentFromNotification){
            Fragment fragment = new TaleActivity_Audio();
            FragmentManager fragmentManager = getSupportFragmentManager();
            fragmentManager.beginTransaction()
                    .replace(R.id.container,fragment)
                    .commit();
        } else {

            mNavigationDrawerFragment = (NavigationDrawerFragment)
                    getSupportFragmentManager().findFragmentById(R.id.navigation_drawer);
            mTitle = getTitle();

            // Set up the drawer.
            mNavigationDrawerFragment.setUp(
                    R.id.navigation_drawer,
                    (DrawerLayout) findViewById(R.id.drawer_layout));

        }

您应该尝试启动包含 Activity 的 fragment 。并放置额外的婴儿车来检测哪个 fragment 必须显示 ListView 或音频 View ，

有点像

Intent notificationIntent = new Intent(getApplicationContext(), viewmessage.class);
notificationIntent.putExtra("showAudioFrag", true);
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingNotificationIntent = PendingIntent.getActivity(getApplicationContext(),notificationIndex,notificationIntent,PendingIntent.FLAG_UPDATE_CURRENT);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.setLatestEventInfo(getApplicationContext(), notificationTitle, notificationMessage, pendingNotificationIntent);

在你的 Activity 中

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);    
    onNewIntent(getIntent());
}

@Override
public void onNewIntent(Intent intent){
    Bundle extras = intent.getExtras();
    boolean reloadFragmentFromNotification = extras .getExtra("showAudioFrag",false);
    if (reloadFragmentFromNotification){
        Fragment fragment = new TaleActivity_Audio();
        FragmentManager fragmentManager = getSupportFragmentManager();
        fragmentManager.beginTransaction()
                .replace(R.id.container,fragment)
                .commit();
    } else {

        mNavigationDrawerFragment = (NavigationDrawerFragment)
                getSupportFragmentManager().findFragmentById(R.id.navigation_drawer);
        mTitle = getTitle();

        // Set up the drawer.
        mNavigationDrawerFragment.setUp(
                R.id.navigation_drawer,
                (DrawerLayout) findViewById(R.id.drawer_layout));

    }
}
