How to change stroke color dynamically?
android, android-studio, shapes
Solution
GradientDrawable myGrad = (GradientDrawable)rectangle.getBackground();
myGrad.setStroke(2, Color.RED);
Problem
(Sorry for my language, I'm french) 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> ``` The answer : ``` GradientDrawable myGrad = (GradientDrawable)rectangle.getBackground(); myGrad.setColor(Color.BLACK); ``` 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. Thanks in advance. EDIT : My Bad, i want to change the Stroke color, not solid.
