Barista is a suite of Android widgets. The suite is currenlty comprised of:
- Audio Visualizer
- Radial Progress Bar Indicator
The audio visualizer widget bridges the gap between audio capture and audio visualization. The widget translates captured audio samples from the time domain to the frequency domain. A histogram of frequency magnitudes is then provided to the developer to visualize the audio spectrum in real time. Two renders are provided as examples of how to use the widget:
- BarRender
- RoundedBarRender
The Radial Progress Indicator provides a visual indicator of progress for an operation. The progress is displayed as a radial arc from [0 .. 360]. The component operates in 3 modes:
- Timer: The application can provide a timeout duration in seconds. The radial indicator will countdown from the duration to 0. A callback is triggered upon reaching 0.
- Percentage: The application can update the amount of progress and the indicator will advance the position radially along the track of the indicator. The overall progress is displayed as a percentage from [0 .. 100] in the center of the radial indicator.
- Fixed: Operates similar to Percentage with the exception that the progress value is rendered as the current value. For example: if the max progress is set to 3000 and the current progress is 500 then 500 will be displayed in the center (as opposed to the percentage).
