I am programming an Android application in Java.
I have the following xml layout:

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:
And the tree of tags looks ok too.
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:
How could I modify the xml file so this doesn't happen, and I can see the hole toolbar?
CodePudding user response：
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.
CodePudding user response：
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.
