實現Android圓環形的滑動條：AndroidCircularSeekBar

AndroidCircularSeekBar實現Android圓環形的滑動條。

用法示例：

public class Welcome extends Activity {
    CircularSeekBar circularSeekbar;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    circularSeekbar = new CircularSeekBar(this);
    circularSeekbar.setMaxProgress(100);
    circularSeekbar.setProgress(100);
    setContentView(circularSeekbar);
    circularSeekbar.invalidate();

    circularSeekbar.setSeekBarChangeListener(new OnSeekChangeListener() {

        @Override
        public void onProgressChange(CircularSeekBar view, int newProgress) {
            Log.d("Welcome", "Progress:" + view.getProgress() + "/" + view.getMaxProgress());
        }
    });

}
