Question

我有listview CompoundDrawable，需要从网上加载化合物drawable中的图片。如何从URL加载图像到CompoundDrawable。我认为我可以从URL获取位图图像将其转换为Drawable，然后将其加载到CompoundDrawable中。像这样

public static Drawable drawableFromUrl(String url) throws IOException {
    Bitmap x;

    HttpURLConnection connection = (HttpURLConnection) new URL(url).openConnection();
    connection.connect();
    InputStream input = connection.getInputStream();

    x = BitmapFactory.decodeStream(input);
    return new BitmapDrawable(x);
}

有更好的方法吗？我可以直接做到这一点，而无需从URL中提取位图，然后将位图转换为drawable？

尝试这个

public static Drawable getDrawableFromURL(String url1) {
    try {
        URL url = new URL(url1);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoInput(true);
        connection.connect();
        InputStream input = connection.getInputStream();
        Bitmap myBitmap = BitmapFactory.decodeStream(input);
        Drawable d = new BitmapDrawable(getResources(),myBitmap);
        return d;
    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }
}

在Compound Drawable From URL中加载图像
