如何从 Android 中按下的滑块中去除发光? [英] How can I remove the glow from a pressed slider in Android?

问题描述

我的 Android 应用中有一个自定义的 SeekBar.当拇指按下时，它周围会出现一种光晕.光环在长时间按下时也会发生变化.我想消除这种光环效应.

I have a custom SeekBar in my Android app. When the thumb is pressed, a kind of halo appears around it. The halo also modifies when it is pressed for a long time. I would like to eliminate this halo effect.

我看过这个 SeekBar 文档 https://developer.android.com/reference/android/widget/SeekBar.html 但看不到任何可以消除它的东西.

I have looked at this SeekBar documentation https://developer.android.com/reference/android/widget/SeekBar.html but do not see anything that can eliminate it.

所以，我的问题是:如何在按下搜索栏拇指时禁用这种光环"效果?

So, my question is: How can I disable this "halo" effect when the seekbar thumb is pressed?

在这个截图中，你可以看到我试图消除的白色光晕.

In this screenshot, you can see the white halo I am trying to eliminate.

提前致谢！

添加 SeekBar xml:

adding SeekBar xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/clip_connect_list_item"
    android:layout_width="fill_parent"
    android:layout_height="@dimen/list_item_radius"
    android:background="@drawable/slider_base"
    android:orientation="horizontal"
    android:clickable="true">
    <SeekBar android:id="@+id/seekBar1"
        android:max="100"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:thumbOffset="0dp"
        android:layout_gravity="center_vertical"
        android:progressDrawable="@color/transparent"
        android:paddingLeft="0dp"
        android:paddingRight="0dp"
        android:paddingTop="0dp"
        android:paddingBottom="0dp"
        >
    </SeekBar>
</LinearLayout>

推荐答案

参加聚会有点晚了，但是将主题的 colorControlHighlight 属性设置为 transparent 很有效我:

A bit late to the party, but setting the colorControlHighlight property to transparent on one's theme worked for me:

<style name="Base.AppTheme" parent="Theme.AppCompat.NoActionBar">
    <!-- This is necessary to remove outward glow appearing on seekbar -->
    <item name="colorControlHighlight">@android:color/transparent</item>
</style>

此相同颜色用于其他 UI 元素上的涟漪效果，因此建议用户自行决定.

This same color is used for the ripple effect on other UI elements, so user discretion advised.
