android– 将图像放在ListView上时,“resolveUri在坏位图uri上失败”

概述嘿,我是Android的新手,我有一个小问题.我正在尝试将列表视图放在一起,图像通过URL加载.这项工作到目前为止,但图像不会出现.logcat说：02-2319:20:48.447:INFO/System.out(833):resolveUrifailedonbadbitmapuri:android.graphics.drawable.BitmapDrawable@405359b0它

嘿,
我是Android的新手,我有一个小问题.我正在尝试将列表视图放在一起,图像通过URL加载.这项工作到目前为止,但图像不会出现. logcat说：

02-23 19:20:48.447: INFO/System.out(833): resolveUri Failed on bad bitmap uri: androID.graphics.drawable.BitmapDrawable@405359b0

它显然没有找到我的形象,但我不明白为什么.使用R.drawable.icon虽然有效.谁能帮我吗？继承人我的来源：

public class Main extends Activity {        private ListVIEw lv_main;    @OverrIDe    public voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentVIEw(R.layout.main);        lv_main = (ListVIEw) findVIEwByID(R.ID.ListvIEwmain);        ArrayList<HashMap<String, String>> ListItem = new ArrayList<HashMap<String, String>>();        HashMap<String,String> map;        map = new HashMap<String, String>();        map.put("Title", "a Title goes here");        map.put("details", "details blaa");        map.put("cover", String.valueOf(Main.this.LoadImageFromWebOperations("http://www.Google.com/intl/en_ALL/images/srpr/logo1w.png"));        //THIS WORKS FINE: map.put("cover", String.valueOf(R.drawable.icon));        ListItem.add(map);        map = new HashMap<String, String>();        map.put("Title", "2nd Title");        map.put("details", "more details");        map.put("cover", String.valueOf(Main.this.LoadImageFromWebOperations("http://www.Google.com/images/srpr/nav_logo37.png"));        //THIS WORKS FINE: map.put("cover", String.valueOf(R.drawable.icon));        ListItem.add(map);        SimpleAdapter mSchedule = new SimpleAdapter (this.getBaseContext(), ListItem, R.layout.ListvIEwitem, new String[] {"cover", "Title", "details"}, new int[] {R.ID.cover, R.ID.Title, R.ID.details});        lv_main.setAdapter(mSchedule);     }    public Drawable LoadImageFromWebOperations(String url) {        try        {                inputStream is = (inputStream) new URL(url).getContent();                Drawable d = Drawable.createFromStream(is, "src name");                return d;        }catch (Exception e) {                System.out.println("Exc="+e);                return null;        }    }}

解决方法:

我已经解决了这个问题.
我正在使用代码来解决问题.

这里’Path’是一个可以使用的本地文件系统路径：Environment.getExternalStorageDirectory().getabsolutePath()

public static String loadImageFromWebOperations(String url, String path) {    try {        inputStream is = (inputStream) new URL(url).getContent();        System.out.println(path);        file f = new file(path);        f.createNewfile();        fileOutputStream fos = new fileOutputStream(f);        try {            byte[] b = new byte[100];            int l = 0;            while ((l = is.read(b)) != -1)                fos.write(b, 0, l);        } catch (Exception e) {        }        return f.getabsolutePath();    } catch (Exception e) {        System.out.println("Exc=" + e);        return null;    }}

希望这可以帮助 ：).
