Fill Drawable

Introduction

Convert any Drawable into filled drawable depending on progress value (.0F - 100.F). One image resource is used. No overdraw, no bitmap allocations.

There are 4 possible directions of progress: from_left, from_top, from_right, from_bottom

Usage

The idea behind FillDrawable is PorterDuffColorFilter, one for normal state & one for progress. The best image resource to use would be solid white

// obtain a Drawable object
final Drawable drawable = getDrawable(...);

// initialize bounds
drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());

// create a FillDrawable
// Note, that you should call `mutate()`, otherwise changes made by FillDrawable
// will be reflected in other places where this drawable is used.
// It has to do it Android drawable cache
final FillDrawable fillDrawable = new FillDrawable(FillDrawable.FROM_LEFT, drawable.mutate())
    .setNormalColor(int color)
    .setFillColor(int color);

...

fillDrawable.setFillPercent(float percent);

Also, there is a FillImageView widget to initialize FillDrawable via XML. Attributes:

app:fiv_normalColor="@color/normal_color"
app:fiv_fillColor="@color/fill_color"
app:fiv_drawable="@drawable/ic_launcher"
app:fiv_from="left" <!-- (left|top|right"bottom) -->
app:fiv_percent="50.0"
