English 中文(简体)
可绘制形状总是灰色
原标题:Shape Drawable is always gray

使用

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <gradient
        android:startColor="#FFFF0000"
        android:endColor="#80FF00FF"
        android:angle="45"/>
    <padding android:left="7dp"
        android:top="7dp"
        android:right="7dp"
        android:bottom="7dp" />
    <corners android:radius="8dp" />
</shape>

每次我把它设定为任何观点的背景时, 总是颠倒背景灰色。

xml是可改用/可改用,我已尝试过指南中使用的两种方法。

有人能解释一下为什么它不起作用吗?

最佳回答

我不知道我怎么修好的,但我复制了我的布局,删除了它们,把它们贴回去,然后清理了项目(我经常这样做),它解决了问题。

使用此代码 :

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <gradient
        android:startColor="#00FFBB"
        android:endColor="#FFEEAA"

      />
    <padding android:left="7dp"
        android:top="7dp"
        android:right="7dp"
        android:bottom="7dp" />
    <corners android:radius="8dp" />
</shape>
