从一项活动转移到另一项活动需要很长时间

Question

在我的应用程序中，我可以注意到，每次我从一项活动转到另一项活动都花了很长时间（1秒或更长时间），而这几乎是瞬间的。我在自己的手机上进行了测试，大约需要2秒钟。我在较新（功能更强大）的服务器上进行了测试，它花费的时间更少，但仍然比应该花费的时间更长。

我不知道我的活动是否很忙，或者我用错误的方式打电话给他们。

从我的MainActivity调用活动：

    public class MainActivity extends AppCompatActivity implements View.OnClickListener {

    private Toolbar toolbar;
    private Anuncio anuncio;
    private TextView titulo;
    private CardView cardView1, cardView2, cardView3, cardView4;
    private View include_1, include_2, include_3, include_4, include_5, include_6, include_7, include_8, include_9;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.contenedor_principal);

        anuncio = new Anuncio();
        anuncio.cargarAnuncios(this, R.id.adView_alone);

        toolbar = findViewById(R.id.toolbar_alone);
        setSupportActionBar(toolbar);
        if (getSupportActionBar() != null) getSupportActionBar().setTitle(null);

        titulo = findViewById(R.id.textview_toolbar_titulo_alone);
        titulo.setText(R.string.app_name);

        inicializar();
    }

    private void inicializar() {
        include_1 = findViewById(R.id.include_objetivos);
        include_1.setVisibility(View.GONE);
        include_2 = findViewById(R.id.include_compras);
        include_2.setVisibility(View.GONE);
        include_3 = findViewById(R.id.include_porCuentas);
        include_3.setVisibility(View.GONE);
        include_4 = findViewById(R.id.include_porQuincena);
        include_4.setVisibility(View.GONE);
        include_5 = findViewById(R.id.include_porInteres);
        include_5.setVisibility(View.GONE);
        include_6 = findViewById(R.id.include_lista_ahorros);
        include_6.setVisibility(View.GONE);
        include_7 = findViewById(R.id.include_ingresos);
        include_7.setVisibility(View.GONE);
        include_8 = findViewById(R.id.include_deudas);
        include_8.setVisibility(View.GONE);
        include_9 = findViewById(R.id.include_home_menu);
        include_9.setVisibility(View.VISIBLE);

        cardView1 = findViewById(R.id.menu_cardView_1);
        cardView2 = findViewById(R.id.menu_cardView_2);
        cardView3 = findViewById(R.id.menu_cardView_3);
        cardView4 = findViewById(R.id.menu_cardView_4);

        cardView1.setOnClickListener(this);
        cardView2.setOnClickListener(this);
        cardView3.setOnClickListener(this);
        cardView4.setOnClickListener(this);
    }


    @Override
    public void onClick(View v) {
        Intent intent;

        switch (v.getId()) {
            case R.id.menu_cardView_1:
                intent = new Intent(this, Menu1.class);
                this.startActivity(intent);
                break;

            case R.id.menu_cardView_2:
                intent = new Intent(this, Menu2.class);
                this.startActivity(intent);
                break;

            case R.id.menu_cardView_3:
                intent = new Intent(this, Menu3.class);
                this.startActivity(intent);
                break;

            case R.id.menu_cardView_4:
                intent = new Intent(this, Menu4.class);
                this.startActivity(intent);
                break;
        }
    }

    @Override
    public void onPause() {
        anuncio.pausar();
        super.onPause();
    }

    @Override
    public void onResume() {
        super.onResume();
        anuncio.resumir();
    }

    @Override
    public void onDestroy() {
        anuncio.destruir();
        super.onDestroy();
    }
}

我删除了所有的“ include”，并使用了一个ViewStub来加载布局，具体取决于用户希望看到的布局。

Main_container.xml：

<ViewStub
android:id="@+id/viewStub"
android:layout_width="match_parent"
android:layout_height="match_parent"/>

MainActivity：

viewStub = findViewById(R.id.viewStub);
viewStub.setLayoutResource(R.layout.home_layout);
viewStub.inflate();
