如何将 output wav 文件从 tts 保存到内部存储，使用下面的代码我将它保存在外部存储中

Question

我能够将音频 wav 文件创建到内部存储，但我想将文件保存在内部存储中，这是我的代码：

 public void speakNow(View v) {
        Log.i(tag, "speakNow [" + et.getText().toString() + "]");
        HashMap<String, String> myHashRender = new HashMap();
        tts.speak(et.getText().toString(), TextToSpeech.QUEUE_FLUSH, null);
        String destFileName = Environment.getExternalStoragePublicDirectory("/Audio007/") + "wakeUp.wav";
        Toast.makeText(this, "" + destFileName, Toast.LENGTH_SHORT).show();
        myHashRender.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, et.getText().toString());
        tts.synthesizeToFile(et.getText().toString(), myHashRender, destFileName);
    }

我可以将音频 wav 文件创建到内部存储，但我想将文件保存在内部存储中，请帮忙。

Answer 1

Place your output to

 fos.write(OUTPUT_FILE_PLACE_HERE);

保存文件的示例代码

  String dir = null;
    dir = getExternalFilesDir("/").getPath() + "/" + "Audio007/";

    Toast.makeText(this, dir, Toast.LENGTH_LONG).show();

    File file = new File(dir, "wakeUp" + ".wav");

    try {
        file.createNewFile();
    } catch (IOException e) {
        e.printStackTrace();
    }
    //write the bytes in file
    FileOutputStream fos = null;
    try {
        fos = new FileOutputStream(file);
        fos.write(OUTPUT_FILE_PLACE_HERE);
        fos.flush();
        fos.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

将文件保存到 SD 卡

  String dir = Environment.getExternalStorageDirectory() + "/Audio007/";
  File file = new File(dir, "wakeUp"+".wav");

  try {
    file.createNewFile();
} catch (IOException e) {
    e.printStackTrace();
}
//write the bytes in file
FileOutputStream fos = null;
try {
    fos = new FileOutputStream(file);
    fos.write(OUTPUT_FILE_PLACE_HERE);
    fos.flush();
    fos.close();
} catch (FileNotFoundException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}
