=============急 安卓 gallery 滑动图片，图片左右跳动怎么解决======

Question

到不了第二张，这不清楚啊，还没遇到过这样的情况，多贴点代码看看，怎么设置的，你要是不太依赖Gallery的话，我建议用viewpage，个人建议。

Answer 1

Gallery没有用过,用下SurfaceView试试？做游戏大多数都是用SurfaceView，显示图片什么的妥妥的

Answer 2

viewPager我用了下，还不如gallery，用viewpaper拖动时，上下的拖动范围不能太大，否则会上下滚动。而不是左右动。
先帮忙看下这个gallery的问题吧。

Answer 3

你的position是不是没有改变过？给份东西你参考下吧。感觉你改一下就可以完成上面的问题了

}以上是一份例子，楼主自己对照，图片需要卤煮自己定义，
一下是布局文件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<!-- 定义一个ImageSwitcher组件 -->
<ImageSwitcher android:id="@+id/switcher"
android:layout_width="320dp"
android:layout_height="320dp"
/>
<!-- 定义一个Gallery组件 -->
<Gallery android:id="@+id/gallery"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="25dp" 
android:unselectedAlpha="0.6"
android:spacing="3pt"
/>
</LinearLayout>
希望能帮助到你

感谢上面各位兄弟回复，不过自己挖的坑自己埋。原因是使用了Image-loader，后来我把Image-loader的内存、硬盘缓存去掉了，好了。。缺点是让他每次都从网上去取吧。话说用框架出现的问题还真是难找啊options = new DisplayImageOptions.Builder()
                .showImageOnLoading(
                        GetItemId.getDrawableResIDByName(context, "suma_default_poster"))
                .showImageForEmptyUri(
                        GetItemId.getDrawableResIDByName(context, "suma_default_poster"))
                .showImageOnFail(GetItemId.getDrawableResIDByName(context, "suma_default_poster"))
//                .cacheInMemory(true)
//                .cacheOnDisc(true)
