请帮我摆脱这个。 这是我的完整代码。 在getProcessedData
中获取异常ArrayStoreException答案 0 :(得分：0)
看到您提供的其余代码，Google找到了
代码的副本https://github.com/phono/PhonoSDK/blob/master/modules/phono-java-audio/src/java/org/xiph/speex/
的实施事实上，更简单的解决方案是
git clone https://github.com/phono/PhonoSDK
您将拥有可能需要的所有代码的副本。
bits.getBuffer（）的返回类型是int。
方法arraycopy仅适用于数组，顾名思义。您必须从一个数组复制到另一个相同类型的数组。您无法从说int[]复制到byte[]，也无法从int复制到byte[]。
BTW如果你有getBufferSize()，你可能希望getBuffer()返回一个大小为byte[] getBufferSize()的缓冲区。您的API似乎有些问题。
答案 1 :(得分：0)
确保数组的数据类型。
System.arraycopy(bits.getBuffer(),0, data, offset,size);
在此行控件中 bits.getBuffer（） -type和数据 -type
你传递了第一个参数的原始数据类型，它必须是Object。你说System.arraycopy(bits.getBuffer(),0, data, offset,size); bits.getBuffer()是原始的而不是对象。
答案 2 :(得分：0)
我不确定你要做什么，但如果我是你，我将按如下方式修改代码。由于代码中包含许多占位符，因此请将其替换为逻辑。
