You can control the busyindicator behavior or look & feel with the following attributes:
- bigpoint_color - The foreground color of the points (circles) on outer radius. By default it is gray.
- smallpoint_color - The foreground color of the point (circle) on the inner radius. By default it is black.
- bigpoint_count - The count of points (circles) on outer radius. By default it is 4. (Range is integer between 4 and 20)
- background_is_visible - true of false. If true you have a light gray rectangle background with rounded corner by default .
- background_color - The background color if visible. By default it is light gray.
- background_shape - The shape of background. (Values could be either rounded_rectangle or circle)
- angle_modifier - The speed multiplicator of the busy indicator. By default it is 1. (Range is integer between 1 and 3)
All of the attributes mentioned in previous section plus
- infinite - true of false. If true the busyindicator is active otherwise the load indicator is active.
- percentage_is_visible - true of false. If true the percentage text appears.
- percentage_decimal_places - Could be : [0, 1, 2]. The decimal places of the percentage text.
- max_value - The max value of the progress.
- stroke_width_multiplier - The width multiplicator of the indicator. (Range is float between 0.2F and 14F)
- load_points_are_visible - true or false. If true the outer points are visible otherwise they are hidden.
- indicator_alpha - The indicator color alpha. By default it is 100. (Range is integer between 100 and 255).

/>Basically just set the maxValue() of busyIndicator and after that set the current value via setValue() frequently like the // NOTE indicates in the code below.
Note : You can set the maxValue with xml attribute as well like app:max_value="756"
For example if you have a progress from 0 to 756, you just set maxValue() to 756 and via setValue() inform the busyIndicator about the progress. BusyIndicator will do the percentage calculations.
busyIndicator = (BusyIndicator) findViewById(R.id.finiteBusyIndicator);
// NOTE : Set the maximum value
busyIndicator.setMaxValue(102);
new BusyIndicatorAsyncTask().execute();
...
class BusyIndicatorAsyncTask extends AsyncTask {
@Override
protected Object doInBackground(Object[] params) {
for (int i = 0; i <= 102; i += 3) {
final int a = i;
runOnUiThread(new Runnable() {
@Override
public void run() {
// NOTE : You can set the current value of BusyIndicator
busyIndicator.setValue(a);
}
});
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
return null;
}
}Actualy it's simple, you can set the angle modifier via setAngleModifier() method at any time. The busy indicator immediately changes the speed once you set it.
class InfiniteBusyModifier extends AsyncTask {
@Override
protected Object doInBackground(Object[] params) {
final Random rand = new Random();
FragmentActivity activity = getActivity();
while (true) {
final int a = rand.nextInt(3) + 1;
activity.runOnUiThread(new Runnable() {
@Override
public void run() {
// NOTE : You can set the speed
infiniteCircleBusyIndicator.setAngleModifier(a);
}
});
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
