【问题描述】:
可能重复:
Is it possible to use BitmapFactory.decodeFile method to decode a image from http location?
我在将 url 图像设置为图像视图时遇到问题。我尝试了以下方法
方法一:
Bitmap bimage= getBitmapFromURL(bannerpath);
image.setImageBitmap(bimage);
public static Bitmap getBitmapFromURL(String src) {
try {
Log.e("src",src);
URL url = new URL(src);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.connect();
InputStream input = connection.getInputStream();
Bitmap myBitmap = BitmapFactory.decodeStream(input);
Log.e("Bitmap","returned");
return myBitmap;
} catch (IOException e) {
e.printStackTrace();
Log.e("Exception",e.getMessage());
return null;
}
}
方法二:
Drawable drawable = LoadImageFromWebOperations(bannerpath);
image.setImageDrawable(drawable);
private 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;
}
}
我尝试了以上两种方法,但都不起作用。两者都显示 DEBUG/skia(266): --- decoder->decode returned false 。我使用了有效的演示 url 图像路径。但这条路行不通。所以请告诉我出了什么问题,我会怎么做
提前谢谢你。
最好的问候。
