我正在尝试使用Gallery小部件构建一组水平滚动的webview.问题是我不能刷视图,这当然适用于图像库.遵循食谱代码,在活动的onCreate()I中:

g = (Gallery) findViewById(R.id.chapter_browser);
g.setAdapter(new WebViewAdapter(this));

然后适配器创建webviews并返回它们以获取所请求的索引:

   public class WebViewAdapter extends BaseAdapter {
        int mGalleryItemBackground;
        private Context mContext;

        private String[] pages = {
                "test1.html",
                "test2.html",
                "test3.html",
                "test4.html"
        };

        public WebViewAdapter(Context c) {
            mContext = c;
        }

        public int getCount() {
            return pages.length;
        }

        public Object getItem(int position) {
            return position;
        }

        public long getItemId(int position) {
            return position;
        }

        public View getView(int position, View convertView, ViewGroup parent) {
            WebView i = new WebView(mContext);

            i.loadUrl("file:///android_asset/" + pages[position]);
            i.setBackgroundResource(mGalleryItemBackground);
            i.setWebViewClient(new WebViewClient()); …
