I have this shape defined in an xml:
<?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:bottomLeftRadius="5dp" ##this need change
android:bottomRightRadius="5dp" ##this need change
android:topLeftRadius="5dp" ##this need change
android:topRightRadius="5dp" /> ##this need change
</shape>
I am creating the following object:
Drawable shape = getResource().getDrawable(R.drawable.myshape);
and I need to modify its radius (or create one with another corner radius).
How can I change the radius? How can I create the shape programmatically?
I solved my problem. The solution is here:
private Drawable getShape(){
GradientDrawable gradientDrawable = new GradientDrawable(GradientDrawable.Orientation.TL_BR, new int[] { startColor,
centerColor, endColor});
gradientDrawable.setGradientType(GradientDrawable.LINEAR_GRADIENT);
gradientDrawable.setCornerRadii(getRandomFloatArray());
gradientDrawable.setGradientCenter(0.0f, 0.45f);
return gradientDrawable;
}
private float [] getRandomFloatArray(){
Random rnd = new Random();
float[] floats = new float[8];
for (int i =0; i < floats.length; i++){
floats[i] = rnd.nextInt(45);
}
return floats;
}
