如何以编程方式在android activity中仅打开文件管理器文件夹中的图像

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

private static final int PICK_IMAGE_REQUEST = 1;

private void openImagePicker() {
    Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
    intent.setType("image/*");
    startActivityForResult(intent, PICK_IMAGE_REQUEST);
}

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

    if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null) {
        Uri imageUri = data.getData();
        // 在这里处理选择的图像文件
    }
}
