Android Studio – Problems with a xml Android layout. The layout overlaps the toolbar

I am programming an Android application in Java.

I have the following xml layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    tools:context="com.geologyapplications.minerals.Ficha"
    android:theme="@android:style/Holo.Light.ButtonBar"
    android:descendantFocusability="beforeDescendants"
    android:focusableInTouchMode="true">

    <androidx.appcompat.widget.Toolbar

        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:minHeight="?attr/actionBarSize"

                        android:text="@string/finalizar"
                        android:id="@+id/finalizar"
                        android:elevation="0dp"
                        android:layout_marginBottom="5dp"
                        android:layout_marginLeft="5dp"
                        android:layout_marginRight="5dp"
                        android:layout_marginTop="5dp"
                        tools:ignore="ButtonStyle,UnusedAttribute"
                        android:textStyle="bold"/>
            </LinearLayout>
        </LinearLayout>
    </ScrollView>
</LinearLayout>

In the Java class I don’t do anything special, I upload the toolbar.

public class QuizGame extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_quiz_game);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        ColorDrawable colorDrawable = new ColorDrawable(Color.parseColor("#000000"));
        toolbar.setBackground(colorDrawable);
        toolbar.setTitleTextColor(Color.WHITE);
//The class is long, it has 400 sentences.

In the design view all looks correct, I don’t see that the layout overlaps the toolbar:

introducir la descripción de la imagen aquí

And the tree of tags looks ok too.

introducir la descripción de la imagen aquí

But launching the activity, in the rigth-top part of the toolbar, a white box appear. It is as if there were a LinearLayout behind the toolbar:

introducir la descripción de la imagen aquí

How could I modify the xml file so this doesn’t happen, and I can see the hole toolbar?

    For I can’t know your toolbar’s style @style/ToolbarTheme and any of actions, I test it without setting any style and actions on the toolbar, there is no problem. It may be cause of your ToolbarTheme.

    I don’t know why, but the buttons were pressing the entire layout up. Supressing android:elevation="0dp", supressing margins and giving a height to the buttons solved the trouble.

    <Button
    android:layout_width="match_parent"
    android:layout_height="70dp"
    android:text="@string/responder"
    android:id="@+id/responder"/>
<Button
    android:layout_width="match_parent"
    android:layout_height="70dp"
    android:text="@string/siguiente"
    android:id="@+id/siguiente"/>
<Button
    android:layout_width="match_parent"
    android:layout_height="70dp"
    android:text="@string/finalizar"
    android:id="@+id/finalizar"/>

    The toolbar is no more overlaped.
