XML ::
<?xml version="1.0" encoding="utf-8"?>
<com.sonyericsson.zoom.ImageZoomView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/zoomview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
请帮帮我...
推荐答案
<?xml version="1.0" encoding="utf-8"?>
<com.sonyericsson.zoom.ImageZoomView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/zoomview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
将其更改为
<?xml version="1.0" encoding="utf-8"?>
<com.Zoom_imageview.zoom.ImageZoomView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/zoomview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
或如果您尚未在项目中添加ImageZoomView类，则请按示例
or if u have not added a class ImageZoomView in your project then plz add it as in example Here
