推荐答案

按照戴夫的建议，您可以将图像分割成1600份250x250px每个。 Photoshop中做到这一点很容易在不到一分钟（这里）。你不必担心编写HTML自己太。一旦你的HTML（可以称之为bigimage.html）和图像文件夹，请将这两个在你的资产的文件夹，并访问他们乐此不疲 -

as per Dave's recommendation, you can split the image into 1600 parts of 250x250px each. Photoshop does this easily in less than a minute (here). You don't have to worry about writing the html yourself too. Once you have the html (lets call it bigimage.html) and the images folder, place both these in your assets folder and access them this way -

    setContentView(webView);
    try {
        webView.loadUrl("file:///android_asset/bigimage.html";
        webView.getSettings().setLoadsImagesAutomatically(true);
    } catch (Exception e) {
        e.printStackTrace();
    }
