Android，设置按钮的背景色会失去波纹效果

问题描述

限时删除！！

将颜色添加到android按钮后，它失去了波纹效果，使用户感觉到响应的点击感.我该如何解决?我搜索了许多解决方案，但找不到明确的解决方案.

After adding color to an android button, it loses its ripple effect that makes the user feel like there is a responsive click. How do I fix this? I've searched through many solutions but I couldn't find a definite one that wasn't ambiguous.

推荐答案

您可以添加波纹效果&具有可绘制的附加波纹的背景色:

You can add the ripple effect & background color with an additionnal ripple drawable:

您的布局:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <Button
        android:id="@+id/button_connect"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="20dip"
        android:fontFamily="sans-serif"
        android:text="Connect"
        android:background="@drawable/ripple"
        android:textColor="#FFFFFF"
        android:textSize="18sp" />

</LinearLayout>

ripple.xml(除了波纹效果之外，您还可以在其中添加背景颜色):

ripple.xml (this is where you can add background color in addition to the ripple effect) :

<?xml version="1.0" encoding="utf-8"?>
<!-- in drawable folder-->
<ripple
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:color="?android:colorControlHighlight">

    <item android:id="@android:id/mask">
        <shape android:shape="rectangle">
            <solid android:color="?android:colorAccent" />
        </shape>
    </item>

    <item>
        <shape android:shape="rectangle">
            <!-- put your background color here-->
            <solid android:color="@color/default_color" />
        </shape>
    </item>

</ripple>
