UIL默认不支持scheme(protocol) [英] UIL doesn't support scheme(protocol) by default

问题描述

我在控制台中收到此错误.

I am getting this error in my console.

UIL doesn't support scheme(protocol) by default ["http://mywebsite.com/mylocation/image.jpg"]. You should implement this support yourself (BaseImageDownloader.getStreamFromOtherSource(...))

我正在尝试将网站中的图像加载到android应用程序中.遵循的步骤:在build.gradle

I am trying to load images from my website into an android application. Steps followed: In build.gradle

dependencies {compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'}

在AndroidManifest.xml

In AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

这是我得到的json输出:

This is the json output I am getting:

"image":"\"http:\\\/\\\/mywebsite.com\\\/mylocation\\\/image.jpg\""

在我的ApplicationActivity.java

In my ApplicationActivity.java

ImageView myImage
myImage = (ImageView)findViewById(R.id.image_id);

我尝试剥离所有不必要参数的网址，如下所示:

I tried stripping the url of all unnecessary parameters as below:

 imageUrl = url.replaceAll("\\[]\"", "");
 imageUrl = imageUrl.replace("\\/","/");

这是ApplicationActivity.java中的代码，我曾尝试使用UniversalImageLoader加载图像:

This is the code in ApplicationActivity.java that I used to try and load the image using UniversalImageLoader:

        DisplayImageOptions defaultOptions = new DisplayImageOptions.Builder()
                .cacheInMemory(true)
                .cacheOnDisk(true)
                .build();
//
        ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(this)
                .defaultDisplayImageOptions(defaultOptions)
                .build();
        ImageLoader.getInstance().init(config); 
Toast.makeText(single_event.this, imageUrl, Toast.LENGTH_LONG).show();
    if(imageUrl != null) {
       //Sets Image
        ImageLoader.getInstance().displayImage(imageUrl, myImage);

    }
  Log.d("URL", imageUrl);

控制台日志和祝酒词均返回引号中正确的网址" http://mywebsite.com/mylocation/image.jpg "

The console log and the toast both return the correct url in quotes "http://mywebsite.com/mylocation/image.jpg"

我错过了一些配置或设置吗?在 ImageLoader.getInstance().displayImage(imageUrl，myImage);之后，我还有什么需要做的??

Is there some configuration or setup i have missed? Is there anything extra I hould do after ImageLoader.getInstance().displayImage(imageUrl, myImage); ?

请协助.

这是布局(下).如果我在布局中将图像源指定为可绘制图像，则从手机加载图像，所有Java逻辑都将被忽略.如果我删除了源，那么什么也没发生< ImageViewandroid:layout_width ="fill_parent"android:layout_height ="120dp"android:id ="@ + id/image_id"android:layout_marginTop ="3dp"android:layout_marginBottom ="3dp"android:contentDescription ="@ string/cnt"android:src ="@ drawable/local_placeholder"/>

This is the layout (below). If I specify the image source in the layout to be an image in drawable, then the image is loaded from the phone and all the java logic is ignored. If I remove the source, then nothing happens <ImageView android:layout_width="fill_parent" android:layout_height="120dp" android:id="@+id/image_id" android:layout_marginTop="3dp" android:layout_marginBottom="3dp" android:contentDescription="@string/cnt" android:src="@drawable/local_placeholder" />

推荐答案

        imageUrl = imageUrl.substring(1, imageUrl.length()-1);

从" http://mywebsite.com/mylocation/image.jpg"解决了问题.
