我正在使用带有Seekbar的自定义拇指。拇指是一个白色圆圈,后面有一个阴影,使用渐变创建。它在大多数情况下按预期工作,但是对于某些设备,我得到错误 java.lang.IllegalArgumentException:radius必须是>加载布局时

java.lang.IllegalArgumentException: radius must be > 0

这似乎只发生在一些罕见的设备上,并且由于乱舞不能报告它们是什么(未识别),我认为它们已经扎根。

在用于创建拇指的xml下面:

<?xml version="1.0" encoding="utf-8"?>

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
 <item android:drawable="@drawable/lockscreen_thumb_shadow"/>
 <item android:drawable="@drawable/lockscreen_thumb_round"
    android:bottom="10dp"
    android:top="10dp"
    android:left="10dp"
    android:right="10dp"/>
</layer-list>

lockcreen_thumb_shadow:

            <?xml version="1.0" encoding="utf-8"?>
            <shape
                android:shape="oval"
                xmlns:android="http://schemas.android.com/apk/res/android">

                <gradient android:type="radial" android:gradientRadius="35dp"
                    android:endColor="#14009FE8"
                    android:centerColor="#96009FE8"

                    android:startColor="#009FE8"
                    android:innerRadius="20dp"
                    />

                <size android:width="70dp" android:height="70dp"/>
            </shape>

lockscreen_thumb_round:

            <?xml version="1.0" encoding="utf-8"?>

            <shape xmlns:android="http://schemas.android.com/apk/res/android"
                android:shape="oval">
                <size android:height="40dp"
                    android:width="40dp" />
                <solid android:color="@android:color/white" />
            </shape>

答案 0 :(得分:2)

当我使用渐变并发现棒棒糖5.0时,我遇到了这个问题,在 gradientRadius 值中存在%问题。

我有这条线:

android:gradientRadius="120%"

并将其更改为:

android:gradientRadius="120%p"

问题解决了。
