当我使用简单的 imageview 或 AspectRatioImageView 时,我能够加载从服务器获取的图像。但是,如果我使用的是 TouchImageView 或 GestureImageView 则无法加载图像。我看到一个空白屏幕。
除了使用 UIL,我还尝试了其他一些加载图像的方法,但结果相同。
但是,当我在 viewpager 中打开一个视图并且它没有显示图像..然后如果我切换到横向模式,然后再切换到纵向模式,那么它能够加载图像..如果我notifyDataSetChanged()
在适配器内的任何地方调用它会崩溃并显示 InflateException
xml
<com.polites.android.GestureImageView
android:id="@+id/imagefullscreen"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerVertical="true"
android:layout_gravity="center"/>
活动
pager.setAdapter(imagePagerAdapter = new ImagePagerAdapter(ImagePagerActivity.this, posts));
pager.setCurrentItem(pos);
PageListener pageListener = new PageListener();
pager.setOnPageChangeListener(pageListener);
imagePagerAdapter.notifyDataSetChanged();
