具有自定义布局的工具栏:左侧为空 space
Toolbar with custom layout: empty space on left side
我正在尝试向我的应用程序添加自定义工具栏。这是布局:
<androidx.appcompat.widget.Toolbar
android:id="@+id/actionbar"
android:layout_width="match_parent"
android:layout_height="50dp"
android:background="@color/colorAccent"
android:elevation="4dp"
android:theme="@style/ThemeOverlay.AppCompat.ActionBar"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light">
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/colorPrimary"
android:orientation="horizontal">
<ImageButton
android:id="@+id/back_button"
android:layout_width="40dp"
android:layout_height="40dp"
android:background="@drawable/ic_arrow_back_black_24dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="LOGO"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.appcompat.widget.Toolbar>
但是工具栏左边框和 ConstraintLayout 起始边框之间有一种间隙(粉红色)
我怎样才能删除它?
添加contentInsetStart="0dp"
:

android:id="@+id/actionbar"
android:layout_width="match_parent"
android:layout_height="50dp"
app:contentInsetLeft="0dp"
