如何在android设备上从pick文件中获取绝对路径？

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("*/*");  // 选择所有类型的文件
startActivityForResult(intent, PICK_FILE_REQUEST_CODE);

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == PICK_FILE_REQUEST_CODE && resultCode == RESULT_OK) {
        Uri uri = data.getData();
        String absolutePath = getAbsolutePathFromUri(uri);
        // 在这里可以使用获取到的绝对路径进行后续操作
    }
}

private String getAbsolutePathFromUri(Uri uri) {
    String[] projection = {MediaStore.Images.Media.DATA};
    Cursor cursor = getContentResolver().query(uri, projection, null, null, null);
    int columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    String absolutePath = cursor.getString(columnIndex);
    cursor.close();
    return absolutePath;
}
