嗨，我的应用程序有问题。在双击之前的一个项目后，它只打开一次，但当我返回选择项目徽标时，标题和背景在之后消失。我的每个布局都有 android:launchMode="singleTop" 在清单中限制打开同一项。我必须重新启动应用程序才能恢复正常
布局代码

public class Organizacje extends AppCompatActivity implements OrgCallback {
    private RecyclerView rvOrg;
    private OrgAdapter orgAdapter;
    private List<Org> mdata;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_organizacje);
        setTitle("Organizacje ekologiczne");
        initViews();
        initmdataOrg();
        setupOrgAdapter();
    }

    private void setupOrgAdapter() {
        orgAdapter = new OrgAdapter(mdata, this);
        rvOrg.setAdapter(orgAdapter);
    }

    private void initmdataOrg() {
        mdata = new ArrayList<>();
        mdata.add(new Org(getString(R.string.unep2), getString(R.string.unep_long_desc),R.drawable.unep));
        mdata.add(new Org(getString(R.string.ksib2), getString(R.string.ksib_long_desc), R.drawable.ksib));
        mdata.add(new Org(getString(R.string.pzfd2), getString(R.string.pzfd_long_desc),R.drawable.pzfd));
    }

    private void initViews() {
        rvOrg = findViewById(R.id.rv_org);
        rvOrg.setLayoutManager(new LinearLayoutManager(this));
        rvOrg.setHasFixedSize(true);
    }

    @Override
    public void onOrgItemClick(int pos, ImageView imgContainer, ImageView imgLogo, TextView title) {
        Intent intent = new Intent(this, OrgDetails.class);
        intent.putExtra("orgObject", mdata.get(pos));
        Pair<View, String> p1 = Pair.create((View)imgContainer,"containerTN");
        Pair<View, String> p2 = Pair.create((View)imgLogo,"logoTN");
        Pair<View, String> p3 = Pair.create((View)title,"titleTN");

        ActivityOptionsCompat optionsCompat = ActivityOptionsCompat.makeSceneTransitionAnimation(this, p1, p2, p3);
        startActivity(intent, optionsCompat.toBundle());
    }
}
