如何在 Neumorphism 设计概念中更改 Android 中的按钮背景?

How to change button background in Android in Neumorphism design concept?

我在我的项目中从事基于 Neumorphism 的设计。我正在使用这个库 https://github.com/fornewid/neumorphism 来实现 Neumorphism 效果。我的问题是我无法更改按钮的背景或任何其他视图。

这是我的布局文件

activity_neumorphism.xml

    <?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/screen_background_gradient"
    tools:context=".NeumorphismActivity">


    <soup.neumorphism.NeumorphButton
        android:id="@+id/button"
        style="@style/Widget.Neumorph.Button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="36dp"
        android:drawablePadding="8dp"
        android:background="@drawable/res_transparent_yellow_roundedfilled_corner"
        android:text="Button"
        android:textColor="#FFFFFF"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent" />

    <Button
        android:id="@+id/normal_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="button"
        android:layout_marginTop="50dp"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        android:background="@drawable/res_transparent_yellow_roundedfilled_corner"/>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constraintTop_toBottomOf="@+id/normal_button"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        android:text="THIS IS NORMAL BUTTON"
        android:textColor="#FFFFFF"
        android:layout_marginTop="30dp"
        />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constraintTop_toBottomOf="@+id/button"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        android:text="THIS IS Neumorphism effect BUTTON"
        android:textColor="#FFFFFF"
        android:layout_marginTop="30dp"
        />

</androidx.constraintlayout.widget.ConstraintLayout>

我在这个 xml 中有两个按钮。一个是普通按钮,另一个是新拟态。我已经为两者设置了背景,但它只适用于普通按钮。

下面给出的是背景的可绘制文件

res_transparent_yellow_roundedfilled_corner.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:shape="rectangle">
    <corners
        android:radius="10dp"
        />


    <gradient
        android:startColor="#C8A800"
        android:endColor="#FFD80A"/>
</shape>

下面给出的是样式。

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="Widget.Neumorph.Button" parent="Widget.AppCompat.Button">
        <item name="android:textAppearance">?android:attr/textAppearanceButton</item>
        <item name="android:minHeight">72dip</item>
        <item name="android:minWidth">112dip</item>
        <item name="android:background">@drawable/res_transparent_yellow_roundedfilled_corner</item>
        <item name="android:paddingLeft">@dimen/design_btn_padding_left</item>
        <item name="android:paddingRight">@dimen/design_btn_padding_right</item>
        <item name="android:paddingTop">@dimen/design_btn_padding_top</item>
        <item name="android:paddingBottom">@dimen/design_btn_padding_bottom</item>
        <item name="android:stateListAnimator">@animator/button_state_list_anim_neumorph</item>
        <item name="android:focusable">true</item>
        <item name="android:clickable">true</item>
        <item name="android:gravity">center_vertical|center_horizontal</item>
        <item name="neumorph_inset">@dimen/design_default_inset</item>
        <item name="neumorph_shadowElevation">6dp</item>
        <item name="neumorph_shadowColorLight">#FFFFFF</item>
        <item name="neumorph_shadowColorDark">#000000</item>
        <item name="neumorph_shapeType">flat</item>
        <item name="neumorph_shapeAppearance">@style/ShapeAppearance.Neumorph.Button</item>

    </style>

    <style name="ShapeAppearance.Neumorph.Button" parent="">

        <item name="background"> @drawable/res_transparent_yellow_roundedfilled_corner</item>

    </style>
</resources>

使用此 属性 更改 xml

中的背景 app:neumorph_backgroundColor="@color/background_color"

如果不行,NeumorphButton里面有一个方法是setBackgroundDrawable。您可以通过编程方式设置可绘制对象

编辑

您不能在此库中设置自定义背景,因为它说

Setting a custom background is not supported.
