问题描述
(抱歉我的语言,我是法语)
(Sorry for my language, I'm french)
我需要更改形状的笔触颜色
.我在此处描述了同样的问题.当 EditText 不正确时,我需要更改纯色.
I need to change the stroke color
of a Shape.
I've the same problem described here.
I need to change solid color when the EditText is not correct.
<?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="#FFFFFF"/>
<corners
android:bottomRightRadius="5dp"
android:bottomLeftRadius="5dp"
android:topLeftRadius="5dp"
android:topRightRadius="5dp"/>
<stroke android:width="2px" android:color="#CCCCCC"/>
</shape>
答案:
GradientDrawable myGrad = (GradientDrawable)rectangle.getBackground();
myGrad.setColor(Color.BLACK);
答案的问题是,我看不懂矩形项.如果我用 EditText 替换它,它将应用于背景,而不是纯色背景.
Problem in the answer is, I don't understand the rectangle item. If I replace it by the EditText, it is applied to the background, not the solid background.
提前致谢.
我的错,我想更改描边颜色,而不是纯色.
EDIT : My Bad, i want to change the Stroke color, not solid.
推荐答案
GradientDrawable myGrad = (GradientDrawable)rectangle.getBackground();
myGrad.setStroke(2, Color.RED);
