vector java java.lang.ArrayIndexOutOfBoundsException：length = 0;索引= 1

Question

当我尝试添加一个对象时，我遇到了问题。请帮助!!!!

Vector BufferTotal = new Vector（）; int n = 1;

while (true) {
    if(AudioRecord.ERROR_INVALID_OPERATION != 0) {
        num = record.read(buffer, 0, 1024);
    }
    track.write(buffer,0, num);
    //Writes the audio data to the audio sink for playback (streaming mode), 
    //or copies audio data for later playback (static buffer mode)
    track.play();
    buffer2=buffer.clone();
    BufferTotal.add(n, buffer2.clone());
    n++;
    throw new IndexOutOfBoundsException("RecandPlay:Error en la posicion "+n+" de "+BufferTotal.size());

}

错误： java.lang.ArrayIndexOutOfBoundsException: length=0; index=1

Answer 1

BufferTotal.add(n, buffer2.clone());

此行导致错误。您试图直接在索引1处添加元素而不是0.使n = 0;并再做一次。

Answer 2

我已将[{1}}替换为BufferTotal.add(int,byte[])，并且应用程序正常运行。
