我正在考虑使用codenameone来实现跨平台的应用程序Win/Mac/Android/iOS。我在Windows上进行开发，对Mac和iOS开发相当无知。我使用的两个特定功能是java.sound API和RandomAccessFile。我很好奇在移动平台上对这些支持是什么样的。以下代码示例是否可以通过codenameone在移动平台（尤其是iOS）上运行？Android和iOS完全支持java.sound和java.util.RandonAccessFile
实施例1：
Mixer.Info[] mixerInfo = AudioSystem.getMixerInfo();
for (int ii = 0; ii < mixerInfo.length; ii++) {
Mixer mixer = AudioSystem.getMixer(mixerInfo[ii]);
Info[] sli = mixer.getSourceLineInfo();
addSink(sinksModel, sli, mixer);
Info[] tli = mixer.getTargetLineInfo();
addSource(sourcesModel, tli, mixer);
}
}
实施例2：
/** Starts playing audio from the current file position. */
public void startPlaying() {
Runnable r = new Runnable() {
@Override
public void run() {
int framePos = sendLastCue();
playing = true;
stopPlaying = false;
while (!stopPlaying) {
try {
int bytes = raf.read(buffer);
if (bytes < 0) {
break;
}
outputLine.write(buffer, 0, bytes);
framePos = sendCues(framePos);
} catch (IOException e) {
e.printStackTrace();
}
}
playing = false;
stopPlaying = true;
for (RecordingListener l : listeners) {
l.playEnded();
}
}
};
new Thread(r).start();
}
实施例3：
/* raf is an instance of RandomAccessFile. */
private void writeDirect(byte[] buf, int offset, int length) throws IOException {
flush();
raf.seek(virtualFilePointer);
raf.write(buf, offset, length);
virtualFilePointer = raf.getFilePointer();
virtualLength = Math.max(virtualLength, raf.length());
virtualFilePointer = raf.getFilePointer();
directWriteCount++;
}
谢谢！
