Java 收缩缩放和viewpager不同时工作

我对android应用程序开发非常陌生，我已经创建了一个ImageGallery应用程序。我正在尝试实现剪辑和缩放画廊中的图像。我用它来实现缩放和收缩。现在的问题是，它不能与视图寻呼机正常工作。如果我删除

photoView.setVisibility（View.GONE）从代码中，我可以缩放图像，但viewpager停止工作，我无法滑动图像。如果我添加
photoView.setVisibility（View.GONE）返回，我可以滑动图像，但不能缩放。我怎样才能解决这个问题

FullImageActivity.java：

public class FullImageActivity extends AppCompatActivity {
    ImageView images;
    int position;
    int folderPosition;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_full_image);
        Intent i = getIntent();
        PhotoView photoView = (PhotoView) findViewById(R.id.photo_view);
        photoView.setVisibility(View.GONE);

        // Selected image id
        position = i.getExtras().getInt("id");
        folderPosition = i.getExtras().getInt("folderPosition");
        Bundle extras = getIntent().getExtras();
        String value = extras.getString("abc");

        Glide.with(FullImageActivity.this)
                .load(value)
                .skipMemoryCache(false)
                .into(photoView);

        ViewPager mViewPager = (ViewPager) findViewById(R.id.viewpager);
        mViewPager.setAdapter(new TouchImageAdapter(this,al_images, folderPosition));
        mViewPager.setCurrentItem(position);
    }

如果要使用滑动图像并放大该图像，则需要使用viewpager进行一些自定义。另一件事是你必须保持viewpager和imageview的触感。检查一下。我希望这将对您有所帮助，您将得到您的解决方案
