Java NetworkImageView类型中的方法setImageUrl（String，ImageLoader）不适用于参数（Uri，ImageLoader）

简而言之，我试图填充一个活动，该活动将显示从JSON数据填充的信息。我已经成功地检索了字符串，但问题解决了检索图像并将其转换为ImageView

我在eclipse中收到以下错误：

The method setImageUrl(String, ImageLoader) in the type NetworkImageView is not applicable for the arguments (Uri, ImageLoader)" at the line hsvimage1.setImageUrl(url1, mImageLoader)

对于以下行：

        hsvimage1.setImageUrl(url1, mImageLoader);
        hsvimage2.setImageUrl(url2, mImageLoader);
        hsvimage3.setImageUrl(url3, mImageLoader);

下面是整个活动代码

public class CasualEventsSingleItemActivity extends Activity {

    // Declare Variables
    String list_item_name;

                new ImageLoader.ImageCache() {

                    cache = new LruCache<String, Bitmap>(20);

            @Override

            }

按照方法的要求将它们设置为字符串

String url1 = list_item_bac;   // e.g. http://example.com/images/image1.png
        String url2 = list_item_bac;
        String url3 = list_item_bac;

同一问题请参见此处

谢谢您的及时回复。当我应用您的建议时，会发生的情况是，当我将Uri设置为字符串并在下面的行list\u item\u bac=Uri.parsei.getStringExtralist\u item\u bac接收到错误时，我无法引用Uri；它已经是一个字符串了，为什么要将其解析为uri？谢谢你的回复。将其更改为以下行时出现的问题：list\u item\u bac=I.getStringExtralist\u item\u bac；我收到以下错误：类型不匹配：无法从字符串转换为Uri最初是这样的-所有字符串，但我遇到了nullpoint异常错误在更新部分的初始帖子下添加了logcat消息，因此尝试调整代码以解决问题。如我所做，我将非常感谢任何指导一段时间以来一直在努力解决这个问题，为什么要将字符串转换为uri，然后返回？当我将其更改为以下行时的问题：list\u item\u bac=I.getStringExtralist\u item\u bac；我收到以下错误：类型不匹配：无法从字符串转换为Uri
