Android 开发：Byte 数组与 Short 数组互转接口实现

Android 开发：Byte 数组与 Short 数组互转接口实现

本文提供两个 Java 接口，分别用于实现 byte 数组转 short 数组和 short 数组转 byte 数组，并附带示例代码和实现。适用于需要在 Android 开发中进行数据类型转换的场景。

接口定义

接口 1：Byte 数组转 Short 数组

public interface ByteToShortConverter {
    short[] convert(byte[] byteArray);
}

接口 2：Short 数组转 Byte 数组

public interface ShortToByteConverter {
    byte[] convert(short[] shortArray);
}

使用示例

public class Main {
    public static void main(String[] args) {
        ByteToShortConverter byteToShortConverter = new ByteToShortConverterImpl();
        ShortToByteConverter shortToByteConverter = new ShortToByteConverterImpl();

        byte[] byteArray = {1, 2, 3, 4};
        short[] shortArray = byteToShortConverter.convert(byteArray);
        System.out.println(Arrays.toString(shortArray)); // [258, 772]

        byte[] convertedByteArray = shortToByteConverter.convert(shortArray);
        System.out.println(Arrays.toString(convertedByteArray)); // [1, 0, 2, 0]
    }
}

实现示例

实现示例 1：Byte 数组转 Short 数组

public class ByteToShortConverterImpl implements ByteToShortConverter {
    @Override
    public short[] convert(byte[] byteArray) {
        int length = byteArray.length / 2;
        short[] shortArray = new short[length];

        for (int i = 0; i < length; i++) {
            shortArray[i] = (short) (((byteArray[i * 2] & 0xFF) << 8) | (byteArray[i * 2 + 1] & 0xFF));
        }

        return shortArray;
    }
}

实现示例 2：Short 数组转 Byte 数组

public class ShortToByteConverterImpl implements ShortToByteConverter {
    @Override
    public byte[] convert(short[] shortArray) {
        int length = shortArray.length * 2;
        byte[] byteArray = new byte[length];

        for (int i = 0; i < shortArray.length; i++) {
            byteArray[i * 2] = (byte) (shortArray[i] >> 8);
            byteArray[i * 2 + 1] = (byte) shortArray[i];
        }

        return byteArray;
    }
}
