如何使图像可滚动？ [Android平台]

Question

I have an image that takes up a lot more space than the android screen. I want the image to be presented full size and the user can move in any direction. Like a map.

Any suggestions?

Answer 1

You can use a webview which gives this to you for free. I'm not sure why but when I tried using the loadData method it didn't work, but using loadDataWithBaseURL with a null URL did.

With a webview your image can even be embedded in HTML. In the example below yourContent is simply a string.

Eg

yourView.loadDataWithBaseURL(null, yourContent, "text/html", "UTF-8", null);

You can put your image in an ImageView and wrap it using a ScrollView and a HorizontalScrollView like below.

<HorizontalScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/yourImage"/>

    </ScrollView>

</HorizontalScrollView>

So you can scroll it horizontally and vertically like a map.

尝试将滚动条与图像放置到xml布局中
