android - 在 ImageView 中显示图像(来自 Url)

Question

我正在使用此代码显示来自 URL 的图像。我的代码运行了，它没有给出错误，但是没有显示图像。有帮助吗？

代码如下:

public class MainActivity extends Activity {

    ImageView i;
    String imageUrl = "http://64.250.238.26:1111/clips/sunsetsofmauisplash.jpg";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        try {
            i = (ImageView) findViewById(R.id.image);
            Bitmap bitmap = BitmapFactory.decodeStream((InputStream) new URL(imageUrl).getContent());
            i.setImageBitmap(bitmap);
        } catch (MalformedURLException e) {

        } catch (IOException e) {

        }

    }
}

试试这个方法，日志代码会告诉你是否有任何异常被抛出

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    try {
       URL url = new URL(imageUrl);
       HttpGet httpRequest = null;

       httpRequest = new HttpGet(url.toURI());

       HttpClient httpclient = new DefaultHttpClient();
       HttpResponse response = (HttpResponse) httpclient.execute(httpRequest);

       HttpEntity entity = response.getEntity();
       BufferedHttpEntity b_entity = new BufferedHttpEntity(entity);
       InputStream input = b_entity.getContent();

       Bitmap bitmap = BitmapFactory.decodeStream(input);

        ImageView i = (ImageView) findViewById(R.id.image);
        i.setImageBitmap(bitmap);
    } catch (MalformedURLException e) {
        Log.e("log", "bad url", t);
    } catch (IOException e) {
        Log.e("log", "io error", t);
    }
}
