android – 具有双标签和缩放缩放的无限画廊图像
作者：互联网
我有app,它的一个活动是无限的厨房,图像存储在res drawable文件夹中,
我想尝试双重标签和缩放图像,
我搜索谷歌没有任何与无限画廊缩放效果有关的例子,
任何建议将被认真考虑 .

更新：
根据Yoann Hercouet的回答我替换此代码：
private ImageView getImageView() {
ImageView i = new ImageView(mContext);
return i;
}
}
使用以下代码：
private GestureImageView getImageView() {
GestureImageView i = new GestureImageView(mContext);
return i;
}
}
还调整了getview,所以最后我的课程如下：

如果我使用我原来的main.xmla修改过的类：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent"

android:background="#FFDAB9">
<com.test.demo.InfiniteGallery
android:id="@+id/galleryOne"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
它使用下面的logcat强制关闭：

更新2
解决方法:
你可以使用自定义imagGallery控件..查看这个https://github.com/kilaka/ImageViewZoom
您可以将图像作为图库视图滑动,并且可以进行缩放缩放.在这个例子中你有一个适配器类..检查出来.
