Question

有没有一种方法可以使微调器位于按钮上方？（我的按钮顶部有很多东西，当您按下按钮时，包括按钮在内的所有内容都将消失）（按钮跨越屏幕的整个宽度）现在是我下方的微调器按钮。我尝试查看其他RelativeLayout设置，但没有用。这是下面的xml代码

编辑：我将按钮和微调器置于框架布局中，当我在手机上对其进行测试时，它可以工作。但是我在更大尺寸（和较新的android版本）的手机上进行了测试，但旋转框没有显示（可能再次隐藏了？）不知道为什么它可以在一部手机上运行而在另一部手机上无法运行，

尝试致电

findViewById(R.id.spinner).bringToFront();

Answer 3

我认为我设法解决了一些问题-创建了一个“ FrameLayout”，然后将微调器和按钮都放在了其中。

应该完成这项工作，除非我发现一个问题，然后再回到这里，这应该得到解决。 :)谢谢

Answer 4

万一有人在想：

我将“按钮”放入FrameLayout中，然后将我想要的元素“置于”其下方（如其下方的代码中）：

<FrameLayout
        android:id="@+id/frameLayout"
        android:layout_width="357dp"
        android:layout_height="58dp"
        android:layout_marginBottom="8dp"
        android:layout_marginEnd="8dp"
        android:layout_marginLeft="8dp"
        android:layout_marginRight="8dp"
        android:layout_marginStart="8dp"
        android:layout_marginTop="8dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.195"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/view"
        app:layout_constraintVertical_bias="0.016">


        <Button
            android:id="@+id/buttontest"
            android:layout_width="393dp"
            android:layout_height="63dp"
            android:layout_marginEnd="24dp"
            android:layout_marginLeft="8dp"
            android:layout_marginRight="24dp"
            android:layout_marginStart="8dp"
            android:background="@drawable/button_shadow"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintHorizontal_bias="0.863"
            app:layout_constraintStart_toStartOf="parent"
            tools:layout_editor_absoluteY="102dp" />


    </FrameLayout>

    <EditText

        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.0"
        app:layout_constraintStart_toEndOf="@+id/spinner"
        app:layout_constraintTop_toTopOf="@+id/frameLayout"
        app:layout_constraintVertical_bias="1.0" />

    <Spinner
        android:id="@+id/spinner"
        android:layout_width="85dp"
        android:layout_height="45dp"
        android:layout_marginBottom="8dp"
        android:layout_marginTop="8dp"
        app:layout_constraintBottom_toBottomOf="@+id/frameLayout"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.06"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="@+id/editText" />
