Android Java字符串操作不起作用

Question

我的问题是，所有字符串操作似乎都不起作用：

String received_message = new String(lmessage, 0, packet.getLength());

注意：收到的信息是“开始。你好。结束”

if (received_message.startsWith("start.") && received_message.endsWith(".end"))
{
    result = 1;
}

received_message = received_message.replace("start.", "");
received_message = received_message.replace(".end", "");

结果:

结果为0，收到的_消息仍然是“start.hello.end”

--

但这是正确的：

if (received_message.startsWith("s") && received_message.endsWith("d"))
{
    result = 1;
}

received_message = received_message.replace("s", "");
received_message = received_message.replace(".", "");

如果我用一个字符来实现这个函数，它就可以工作了

我怎样才能让它对整个字符串起作用

问题在于编码。Windows服务器使用Unicode，Android系统使用UTF-16作为标准。因此字符串包含一些不可见的字符
