java - 无法使用 photoview 库缩放图像

Question

我正在使用 here 中的 PhotoView 库。它没有给出任何错误，但我无法缩放图像。尝试缩放图像时没有任何反应。我也没有从 build.gradle 收到任何错误。我该如何解决这个问题？

FullImageActivity.java:

public class FullImageActivity extends AppCompatActivity {
    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);


        // 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);
    }
}

activity_full_image.xml:

<?xml version="1.0" encoding="utf-8"?>

     <LinearLayout
         xmlns:android="http://schemas.android.com/apk/res/android"
         android:id="@+id/jazzy_pager"
         android:layout_width="match_parent"
         android:layout_height="match_parent">


     <android.support.v4.view.ViewPager
         android:id="@+id/viewpager"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content" />

     <com.github.chrisbanes.photoview.PhotoView
         android:id="@+id/photo_view"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         android:layout_gravity="center"
         android:scaleType="centerCrop"/>


</LinearLayout>

试试这个代码:

  Glide.with(FullImageActivity.this)
                    .load(value)
                    .asBitmap()
                    .diskCacheStrategy(DiskCacheStrategy.SOURCE)
                    .into(new SimpleTarget<Bitmap>() {
                        @Override
                        public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) {
                            photoView.setImageBitmap(resource);
                        }
                    });
