我有一个图形在定义的XML 。现在我需要改变纯色从code，请你指教怎么样？

 ＆LT; XML版本=1.0编码=UTF-8＆GT？;
＆LT;形状的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android
    机器人：形状=矩形机器人：填充=10dp＆GT;
    [固体机器人：颜色=＃000000/＆GT;
    ＆LT;角落
        机器人：bottomRightRadius =8DP
        机器人：bottomLeftRadius =8DP
        机器人：topLeftRadius =0dp
        机器人：topRightRadius =0dp/＆GT;
＆LT; /形状＆GT;
 

解决方案

我用这个在我的code

  GradientDrawable myGrad =（GradientDrawable）rectangle.getBackground（）;
myGrad.setColor（Color.BLACK）;
 

希望这有助于：）

编辑：代替 ShapeDrawable

I have a Shape defined in xml. Now I need to change a solid color from the code, could you please advice how?

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" android:padding="10dp">
    <solid android:color="#000000"/>
    <corners
        android:bottomRightRadius="8dp"
        android:bottomLeftRadius="8dp"
        android:topLeftRadius="0dp"
        android:topRightRadius="0dp"/>
</shape>

I use this in my code

GradientDrawable myGrad = (GradientDrawable)rectangle.getBackground();
myGrad.setColor(Color.BLACK);

Hope this helps :)

EDIT: for GradientDrawable instead of ShapeDrawable
