Android 故障设置位置到录制的音频

我必须在Android上启动以下代码和录音机：

final Intent recordSoundIntent = new Intent
("android.provider.MediaStore.RECORD_SOUND");
String fileName = Environment.getExternalStorageDirectory() +
File.separator + UUID.randomUUID() + ".3gpp";
recordSoundIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new
File(fileName)));
startActivityForResult(Intent.createChooser(recordSoundIntent,
getString(R.string.record_sound_chooser)), INTENT_SOUND_RECORDING);

我的问题如下：

我的文件名（filename）无效，从 data.getData（）在上次测试运行中返回：content://media/external/audio/media/41. 但是，此文件是在我的SD卡上创建的：recording34485.3gpp。如果是 无法在创建声音时设置自定义位置，因为它是

我想要此文件的位置。

正在处理相同的问题。无法找到直接设置位置的方法，但找到了获取和重命名位置的解决方案

处理文件名时，使用java.io.file.renameTo（）重命名文件。您需要在清单文件中使用android.permission.WRITE_EXTERNAL_存储，重命名才能生效

下面是我的测试代码示例：

public static final int REQUEST_RECORD_SOUND = 7;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main2);

    Button button = (Button) findViewById(R.id.button1);
    button.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            Intent intent  = new Intent(MediaStore.Audio.Media.RECORD_SOUND_ACTION);
            startActivityForResult(intent, REQUEST_RECORD_SOUND);
        }
    });
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);

    if (requestCode == REQUEST_RECORD_SOUND){
        String sourcePath = getRealPathFromURI(intent.getData());
        File root = Environment.getExternalStorageDirectory();
        String destPath = root.getPath() + File.separator + "newName.txt";
        File sourceF = new File(sourcePath);
        try {
            sourceF.renameTo(new File(destPath));
        } catch (Exception e) {
            Toast.makeText(this, "Error:" + e.getMessage(), Toast.LENGTH_LONG).show();
        }
    }
}
