Usage

From source file:io.doist.datetimepicker.time.RadialTimePickerView.java

private void drawDebug(Canvas canvas) {
    // Draw outer numbers circle
    final float outerRadius = mCircleRadius[HOURS] * mNumbersRadiusMultiplier[HOURS];
    canvas.drawCircle(mXCenter, mYCenter, outerRadius, mPaintDebug);

    // Draw inner numbers circle
    final float innerRadius = mCircleRadius[HOURS] * mNumbersRadiusMultiplier[HOURS_INNER];
    canvas.drawCircle(mXCenter, mYCenter, innerRadius, mPaintDebug);

    // Draw outer background circle
    canvas.drawCircle(mXCenter, mYCenter, mCircleRadius[HOURS], mPaintDebug);

    // Draw outer rectangle for circles
    float left = mXCenter - outerRadius;
    float top = mYCenter - outerRadius;
    float right = mXCenter + outerRadius;
    float bottom = mYCenter + outerRadius;
    canvas.drawRect(left, top, right, bottom, mPaintDebug);

    // Draw outer rectangle for background
    left = mXCenter - mCircleRadius[HOURS];
    top = mYCenter - mCircleRadius[HOURS];
    right = mXCenter + mCircleRadius[HOURS];
    bottom = mYCenter + mCircleRadius[HOURS];
    canvas.drawRect(left, top, right, bottom, mPaintDebug);

    // Draw outer view rectangle
    canvas.drawRect(0, 0, getWidth(), getHeight(), mPaintDebug);

    // Draw selected time
    final String selected = String.format("%02d:%02d", getCurrentHour(), getCurrentMinute());

    ViewGroup.LayoutParams lp = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
            ViewGroup.LayoutParams.WRAP_CONTENT);
    TextView tv = new TextView(getContext());
    tv.setLayoutParams(lp);/*from  w w  w. ja v  a 2 s  .co  m*/
    tv.setText(selected);
    tv.measure(MeasureSpec.UNSPECIFIED, MeasureSpec.UNSPECIFIED);
    Paint paint = tv.getPaint();
    paint.setColor(DEBUG_TEXT_COLOR);

    final int width = tv.getMeasuredWidth();

    float height = paint.descent() - paint.ascent();
    float x = mXCenter - width / 2;
    float y = mYCenter + 1.5f * height;

    canvas.drawText(selected, x, y, paint);
