Customization
Here is a list of all attributes, set with default values
<com.doctoror.particlesdrawable.ParticlesView
app:minDotRadius="1dp"
app:maxDotRadius="3dp"
app:lineThickness="1dp"
app:lineDistance="86dp"
app:numDots="60"
app:dotColor="@android:color/white"
app:lineColor="@android:color/white"
app:frameDelayMillis="10"
app:stepMultiplier="1"/>The conventional getters and setters are also available.
Since API 24, you may also customize the Drawable in xml. For example, create drawable-v24/particles_120dots.xml
<?xml version="1.0" encoding="utf-8"?> <!-- Some versions of Android Studio may show false warning, "Element drawable must be declared", but it works fine when compiling and running --> <drawable
class="com.doctoror.particlesdrawable.ParticlesDrawable"
xmlns:app="http://schemas.android.com/apk/res-auto"
app:numDots="120"/>And inflate, like
mDrawable = (ParticlesDrawable) ContextCompat
.getDrawable(this, R.drawable.particles_120dots);
