Question

我想从某个网址中获取网络图片并在我的ImageView中显示。以下是我正在使用的代码： -

Bitmap bm = null;
    try {
         URL aURL = new URL("stringURL"); 
         URLConnection conn = aURL.openConnection();
         conn.connect(); 
         InputStream is = conn.getInputStream();
         BufferedInputStream bis = new BufferedInputStream(is);
         bm = BitmapFactory.decodeStream(bis);
         bis.close();
         is.close(); 
    }catch (Exception e) {
        // TODO: handle exception
}
    iv.setImageBitmap(bm);

但我无法获得图片

Answer 1

我认为错误在

URL aURL = new URL("stringURL");

应该没有引号

URL aURL = new URL(stringURL);

如果stringURL是有效网址，它将起作用...

希望它有帮助../

Answer 2

我认为你可以使用下面的代码，这对我来说效果很好。

String stringURL = "Your url here";

InputStream is = null;
BufferedInputStream bis = null;
Bitmap bmp = null;

try {
    URL url = new URL(stringURL);   
    URLConnection conn = url.openConnection();
    conn.connect();
    is = conn.getInputStream();
    bis = new BufferedInputStream(is);
    bmp = BitmapFactory.decodeStream(bis);

} catch (MalformedURLException e) {

} catch (IOException e) {

}catch (Exception e) {

} finally {
    try {
        if( is != null )
            is.close();
        if( bis != null )
            bis.close();
    } catch (IOException e) {

    }
}
iv.setImageBitmap(bmp);

setImageURI / setimagebitmap从网络中获取图像并在图像视图中显示
