Question

我需要在TextView中插入一个drawable，我在代码中从web下载。因此，我无法手动将图像放入res和R.drawable中。

我该如何使用它？

Answer 1

步骤：

1）下载图片

2）转换为drawable

3）通过调用smth将drawable设置为textView：

textView.setCompoundDrawablesWithIntrinsicBounds(R.drawable.icon, 0, 0, 0);

Answer 2

试试这个

try {
    /* Open a new URL and get the InputStream to load data from it. */
    URL aURL = new URL("ur Image URL");
    URLConnection conn = aURL.openConnection();
    conn.connect();
    InputStream is = conn.getInputStream();
    /* Buffered is always good for a performance plus. */
    BufferedInputStream bis = new BufferedInputStream(is);
    /* Decode url-data to a bitmap. */
    Bitmap bm = BitmapFactory.decodeStream(bis);
    bis.close();
    is.close();

    Drawable d =new BitmapDrawable(bm);
    d.setId("1");
    textview.setCompoundDrawablesWithIntrinsicBounds(0,0,1,0);// wherever u want the image relative to textview
    } catch (IOException e) {
    Log.e("DEBUGTAG", "Remote Image Exception", e);
    }
