推荐答案

试图将谷歌图表转换为位图，并设置为你的形象到您的ImageView。

try to convert your google chart as bitmap and set as your image to your imageview.

为前：

Bitmap bitmap = loadChart("your google image url");

和loadChart方法

and loadChart method is

private Bitmap loadChart(String urlRqs) {
        Bitmap bm = null;
        InputStream inputStream = null;

        try {
            inputStream = OpenHttpConnection(urlRqs);
            bm = BitmapFactory.decodeStream(inputStream);
            inputStream.close();
        } catch (IOException e) {
            e.printStackTrace();
        }

        return bm;
    }

和 OpenHttpConnection 是

private InputStream OpenHttpConnection(String strURL) throws IOException {

        InputStream is = null;
          URL url = new URL(strURL);
          URLConnection urlConnection = url.openConnection();

          try{
           HttpURLConnection httpConn = (HttpURLConnection)urlConnection;
           httpConn.setRequestMethod("GET");
           httpConn.connect();

           if (httpConn.getResponseCode() == HttpURLConnection.HTTP_OK) {
            is = httpConn.getInputStream(); 
           }
          }catch (Exception ex){
              Log.e("###","",ex);
          }

        return is;
    } 

最后，你可以通过以下code将位图图像视图的背景。

And finally you can set your bitmap as your image view background by using following code.

image.setImageBitmap(bitmap);
