Change fillColor of a vector in android programmatically
This is exactly what you need. Credits to @emmaguy, the author of the post. I just added the full support of Support Library 23.4+, which enables you to stop generating pngs at runtime:
// Gradle Plugin 2.0+
android {
defaultConfig {
vectorDrawables.useSupportLibrary = true
}
}
And if this line is set on your Activity's or Application's onCreate:
AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
You can use your SVGs not only with srcCompat
but also with other attributes such as drawableLeft
, background
, etc. in TextView, ToggleButton and so on. It also works if used on selectors.
Note: I modified the code to use VectorDrawableCompat.create
instead of ResourcesCompat.getDrawable
. Otherwise it would not work and throw org.xmlpull.v1.XmlPullParserException: Binary XML file line #2: invalid drawable tag vector
.
Medium post content:
First, we create attributes for the two kinds of bauble, so we can change their colours:
<declare-styleable name="ChristmasTree">
<attr name="bauble_round" format="color" />
<attr name="bauble_small" format="color" />
</declare-styleable>
Then, in the VectorDrawable, set the parts we want to dynamically change to use these attributes:
<path
android:fillColor="?attr/bauble_round"
android:pathData="...." />
<path
android:fillColor="?attr/bauble_small"
android:pathData="...." />
...
Create themes and set the colours you want to use:
<style name="UpdatedScene" parent="DefaultScene">
<item name="bauble_round">#db486e</item>
<item name="bauble_small">#22c7f7</item>
</style>
<style name="DefaultScene">
<item name="bauble_round">#fec758</item>
<item name="bauble_small">#f22424</item>
</style>
Use the drawable in an ImageView:
final ContextThemeWrapper wrapper = new ContextThemeWrapper(this, R.style.DefaultScene);
final Drawable drawable = VectorDrawableCompat.create(getResources(), R.drawable.christmas, wrapper.getTheme());
imageView.setImageDrawable(drawable);
That’s it! When you want to change the colours, simply set a different theme and your drawable will update. See the GitHub repo for a full sample.
If you want to change the whole color, you could apply a PorterduffColorFilter.
But this does not work for a single <path>
. Only for the whole drawable.
public void applyThemeToDrawable(Drawable image) {
if (image != null) {
PorterDuffColorFilter porterDuffColorFilter = new PorterDuffColorFilter(Color.BLUE,
PorterDuff.Mode.SRC_ATOP);
image.setColorFilter(porterDuffColorFilter);
}
}
VectorDrawable extends the Drawable class. See Docs
add setColorFilter()
method to your image content vector (is added in api level 8) like this:
imgshare = (Imageview) findviewbyId(R.id.imageshare);
imgshare.setColorFilter(color);
button.setColorFilter(getResources().getColor(R.color.YOUR_COLOR));
example:
dislikeBtn.setColorFilter(getResources().getColor(R.color.grey));
None of these answers worked for changing the color of a vector path inside a drawable at runtime. In fact, I still didn't figure that out, but I think this answer would help a lot of people who are just trying to create and paint a simple shape at runtime.
I was trying to create a custom border Mvvm binding to customise the border & fill colors of a Button at runtime. For a while I was trying to modify an Android drawable to achieve this but found out that wasn't possible. Eventually I figured out how to do this with GradientDrawable.
I'm using Xamarin.Android in C# so it does look slightly different from Java.
GradientDrawable gd = new GradientDrawable();
gd.SetColor(Color.Red);
gd.SetCornerRadius(10);
gd.SetStroke(3, Color.White);
view.Background = gd;
