How to

The library use the standard String path information (only one path) and the original size to works, you need to obtain it using a external tool, the path information look like this:

M306.314,58.9801 C275.235,27.9011,224.837,27.9011,193.759,58.9801

And the width and height can be found in the svg definition:

height="316"
width="512"

Using the view (Samples)

Two way

      />

Material

<com.github.glomadrian.roadrunner.IndeterminateRoadRunner

     lib:path_original_height="@integer/twitter_original_height"
     lib:path_animation_type="material"
     />

Determinate Two way

<com.github.glomadrian.roadrunner.DeterminateRoadRunner
    android:id="@+id/determinate"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    lib:min="0"
    lib:max="100"
    lib:movement_direction="counter_clockwise"
    lib:path_color="@color/colorAccent"

    lib:path_data="@string/clip"
    lib:path_original_width="@integer/clip_original_width"
    lib:path_original_height="@integer/clip_original_height"
    lib:animate_on_start="false"
    />

Custom attributes

Common

• movement_direction: clockwise or counter_clockwise
• path_color: color of the painted path
• stroke_width: width of the painted path
• path_data: String with the path information
• path_original_width: The original with defined in the SVG
• path_original_height: The original height defined in the SVG
• animate_on_start: true or false, init the animation on first paint (true by default)

Indeterminate

• path_animation_type: Select indetermina animation type, can be:
  • material
  • twoWay

Indeterminate Material

• Dont have any custom attributes

Indeterminate Two way

• movement_loop_time:** Time take to do a complete loop
• line_size:* The size of the base line
• left_line_animation_time: Time take to do a complete animation to the left line
• right_line_animation_time: Time take to do a complete animation to the right line
• left_line_max_size:* The max size that the left line can research in the animation
• right_line_max_size:* The max size that the right line can research in the animation
• left_line_animation_start_delay: Time to wait to start the left line animation (in milliseconds)
• right_line_animation_start_delay: Time to wait to start the right line animation (in milliseconds)

* From 0f to 1f, 1f is all the path

Determinate

• min: Min value for the progress
• max: Max value for the progress
• movement_loop_time: Time take to do a complete loop
• movement_line_size:* The size of the line

* From 0f to 1f, 1f is all the path
