I'm trying to add a Toolbar on my app and i have a little space on the left of linear layout.

This is the code of my main activity layout, i tried to change padding and margin of all the element but the situation doasn't change.

Does anyone know why?

Answer 1

Preview in my Android Studio The problem is with caches

Try

• Copy the file content
• Delete the file
• File > Invalidate & Restart
• Gradle sync
• Create new file with different name
• Check the preview
• Run the app and check
• Rename to original name

Could you try

 app:contentInsetLeft="0dp"
 app:contentInsetStart="0dp"
 android:padding="0dp"

it will be like this

<androidx.appcompat.widget.Toolbar
    android:id="@+id/myToolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:contentInsetLeft="0dp"
    app:contentInsetStart="0dp"
    android:padding="0dp">
