找不到符号：collection-HashSet

我在试图让这个程序工作时遇到一些问题，任何帮助都将不胜感激

<div class=" modal fade" id="win" role="dialog">
    <div class="modal-dialog">

         <!-- Modal content-->

Answer 1

两件事：

导致您遇到错误的第一个是HashSet类的错字。它应该是：

        Utils.logcat(Const.LOGD, encTag, "MediaCodec encoder thread has started");
        isEncoding = true;
        byte[] amrbuffer = new byte[32];
        short[] wavbuffer = new short[160];
        int outputCounter = 0;

        //setup the wave audio recorder. since it is released and restarted, it needs to be setup here and not onCreate
        wavRecorder = null; //remove pointer to the old recorder for safety
        wavRecorder = new AudioRecord(MediaRecorder.AudioSource.MIC, SAMPLESWAV, AudioFormat.CHANNEL_IN_MONO, FORMAT, 160);
        wavRecorder.startRecording();
        AmrEncoder.init(0);

        while(!micMute)
        {
            int totalRead = 0, dataRead;
            while(totalRead < 160)
            {//although unlikely to be necessary, buffer the mic input
                dataRead = wavRecorder.read(wavbuffer, totalRead, 160 - totalRead);
                totalRead = totalRead + dataRead;
            }
            int encodeLength = AmrEncoder.encode(AmrEncoder.Mode.MR122.ordinal(), wavbuffer, amrbuffer);

            try
            {
                Vars.mediaSocket.getOutputStream().write(amrbuffer);
                Vars.mediaSocket.getOutputStream().flush();
            }
            catch (IOException i)
            {
                Utils.logcat(Const.LOGE, encTag, "Cannot send amr out the media socket");
                Utils.dumpException(tag, i);
            }

第二个是当你调用HashSet < String> hs= new HashSet< String>();的迭代器方法时，它应该是HashSet而不是hs.iterator()（请注意）。

Answer 2

Hashset<String> hs= new HashSet<String>();

在上面的行中你需要将Hashset改为HashSet

因为类的实际名称是HashSet而你编写Hashset所以类名不匹配。

找不到符号：同时使用Collection-HashSet
