我在将 Java 编写的函数转换为 Kotlin 特定函数时遇到问题。
这是用Java编写的:
private boolean isOldOemCommissioningFormat(byte[] assetData) {
if (assetData == null
|| assetData.length < mAssetDataDelimeterByteCount + mAssetDataOwnerIdByteCount + mAssetDataIdLeadingZerosByteCount + mAssetDataIdByteCount)
return false;
int oemMarkerIndex = mAssetDataDelimeterByteCount + mAssetDataIdLeadingZerosByteCount + mAssetDataIdByteCount;
if (assetData[oemMarkerIndex] == PARTIAL_OEM_MARKER || assetData[oemMarkerIndex] == FULL_OEM_MARKER)
return ((assetData[oemMarkerIndex + 1] >> 6) & 0x01) == 0;
return false;
}
但是，当我使用 Android Studio IDE 转换器转换为 Kotlin 时，它给了我这个:
private fun isOldOemCommissioningFormat(assetData: ByteArray?): Boolean {
if (assetData == null || assetData.size < mAssetDataDelimeterByteCount + mAssetDataOwnerIdByteCount + mAssetDataIdLeadingZerosByteCount + mAssetDataIdByteCount)
return false
val oemMarkerIndex = mAssetDataDelimeterByteCount + mAssetDataIdLeadingZerosByteCount + mAssetDataIdByteCount
return if (assetData[oemMarkerIndex] == PARTIAL_OEM_MARKER || assetData[oemMarkerIndex] == FULL_OEM_MARKER) assetData[oemMarkerIndex + 1] shr 6 and 0x01 == 0 else false
}
我猜它给出了错误的转换，而且“shr”被标记为红色作为未解析的引用。
如何正确转换？
其他变量是:
public static final byte PARTIAL_OEM_MARKER = '#';
public static final byte FULL_OEM_MARKER = '&';
public static final int OEM_COMMISSIONING_CUSTOMER_ID_ENCODING_CHARACTERS_COUNT = 40;
public static final int OEM_COMMISSIONING_CUSTOMER_ID_ENCODING_FIRST_CHARACTER_INDEX = 64;
和
private final int mAssetDataIdLeadingZerosByteCount;
private final int mAssetDataIdByteCount;
private final int mAssetDataDelimeterByteCount;
private final int mAssetDataOwnerIdByteCount;
最佳答案
在 Kotlin 中“shr”仅适用于 Int 和 Long，请尝试转换您的值
assetData[oemMarkerIndex + 1].toInt()
