如何在点击推送通知时打开Fragment

我的 Firebasemessagingservice 类代码用于传递意图：

private void showNotification(String message){
    Intent intent=new Intent(this, DrawerActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    intent.putExtra("data", message);
    PendingIntent pendingIntent=PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder builder=new NotificationCompat.Builder(this)
            .setAutoCancel(true)
            .setContentTitle("Registry")
            .setContentText(message)
            .setSmallIcon(R.drawable.com_facebook_button_send_icon_blue)
            .setContentIntent(pendingIntent);
    NotificationManager manager=(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    manager.notify(0,builder.build());
}

onCreate() 方法中我的 Fragment BaseActivity 代码：

Intent notifyIntent = getIntent();
    Bundle extras = notifyIntent.getExtras();
    if (extras != null) {

       replacefragment code;

    }

它不工作..

首先，在代码中，您是否让通知声明了以下方式的意图：

Intent intent=new Intent(getApplicationContext(), MyClass.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("menuFragment", "MyFragment");
PendingIntent pendingIntent=PendingIntent.getActivity(MyClass.this,0,intent,PendingIntent.FLAG_UPDATE_CURRENT);

将意图分配给 mBuilder

mBuilder.setContentIntent(pendingIntent);

然后转到 Activity main 并在 onCreate 方法中添加以下代码：

protected void onCreate(Bundle savedInstanceState) {
    onNewIntent(getIntent());
}

最后在MainActivity中添加这个方法：

@Override
    protected void onNewIntent(Intent intent) {
        Bundle extras = intent.getExtras();
        if(extras != null){
            if(extras.containsKey("menuFragment"))
            {
                FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
                fragmentTransaction.replace(R.id.detail_fragment_container, MyFragment.newInstance() ).commit();
            }
        }
    }
