有没有办法将 IR 模式从 Android ~4.4.2 转换为 4.4.3 兼容模式。Android ~4.4.2 使用了多个周期，而 4.4.3 使用了以 µs 为单位的开启和关闭时间。

这是它们的外观示例

private static final int SAMPLE_FREQ = 38400;
private static final int[] IR_SIGNAL_PULSE_COUNT = {171,171,22,64,22,64,22,64,22,21,22,21,22,21,22,21,22,21,22,64,22,64,22,64,22,21,22,21,22,21,22,21,22,21,22,21,22,21,22,64,22,21,22,21,22,21,22,21,22,21,22,64,22,64,22,21,22,64,22,64,22,64,22,64,22,64,22,876};

private static final int[] IR_SIGNAL_TIME_LENGTH = {4499,4499,578,1683,578,1683,578,1683,578,552,578,552,578,552,578,552,578,552,578,1683,578,1683,578,1683,578,552,578,552,578,552,578,552,578,552,578,552,578,552,578,1683,578,552,578,552,578,552,578,552,578,552,578,1683,578,1683,578,552,578,1683,578,1683,578,1683,578,1683,578,1683,578,23047};

理论上这应该有效，但它没有

private int[] toCompIR(IrDataCompat data){
    int inUs = 1000000/data.getFrequency();
    int[] frame = data.getFrame();
    int[] arrayOfInt = new int[-1 + frame.length];
    for (int j = 1; j < frame.length; j++)
        arrayOfInt[(j - 1)] = frame[(j - 1)] * inUs;

    return arrayOfInt;
}

您可能会遇到舍入错误。

请试试

浮动 inUs = 1000000.0f/data.getFrequency()
