Android 【將圖片網址Url轉化爲Bitmap工具類】

需求將圖片的url轉爲Bitmap格式

代碼如下

public class BitMapUtil {

    private Bitmap bitmap;

    public Bitmap returnBitMap(final String url){

        new Thread(new Runnable() {
            @Override
            public void run() {
                URL imageurl = null;

                try {
                    imageurl = new URL(url);
                } catch (MalformedURLException e) {
                    e.printStackTrace();
                }
                try {
                    HttpURLConnection conn = (HttpURLConnection)imageurl.openConnection();
                    conn.setDoInput(true);
                    conn.connect();
                    InputStream is = conn.getInputStream();
                    bitmap = BitmapFactory.decodeStream(is);
                    is.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }).start();

        return bitmap;
    }
}
