如何在Android中更改XML中按钮的textColor？(How to change textColor of a button from XML in Android?)

 我相信以下是我的问题的最佳答案之一。 我已经将@ 0andriy提供的链接用于内核源代码中的现有示例。 
 
 转换带符号的16位值进行传输 
 
s16 src = -5;
u8 dst[2];
__be16 tx_buf;
*(__be16*)dst = cpu_to_be16(src);
 
 转换多个带符号的16位值进行传输 
 
s16 src[2] = {-5,-2};
u8 dst[4];
s16* psrc = src;
u8* pdst = dst;
int len = sizeof(src);

for ( ; len > 1; len -= 2) {
    *(__be16 *)pdst = cpu_to_be16p(psrc++);
    pdst += 2;
}
 
 快速免责声明，我仍然需要检查此代码是否正确/编译。 
 
 总的来说，我对复制和转换多个值的字节序的解决方案有点不满意，因为它很容易出现拼写错误并且可以很容易地实现到宏中。 

I believe the following is one of the best answers to my question. I have used the links provided by @0andriy to existing examples in the kernel source code.
 
Converting a signed 16-bit value for transmitting
 
s16 src = -5;
u8 dst[2];
__be16 tx_buf;
*(__be16*)dst = cpu_to_be16(src);
 
Converting multiple signed 16-bit values for transmitting
 
s16 src[2] = {-5,-2};
u8 dst[4];
s16* psrc = src;
u8* pdst = dst;
int len = sizeof(src);

for ( ; len > 1; len -= 2) {
    *(__be16 *)pdst = cpu_to_be16p(psrc++);
    pdst += 2;
}
 
A quick disclaimer, I still need to check if this code is correct / compiles.
 
Overall, I'm a bit unsatisfied with the solution for copying and converting the endianness of multiple values since it is prone to typos and could easily be implemented into a macro.
