简单的网络图片查看

public void visit(View view) {

if(TextUtils.isEmpty(imagetAdress)) {
Toast.makeText(this, "访问路径不能为空！", 0).show();
} else {
new Thread(){
public void run() {
try {
URL url = new URL(imagetAdress);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
conn.setConnectTimeout(5000);
if(conn.getResponseCode()==200) {
InputStream is = conn.getInputStream();
Bitmap bitmap= BitmapFactory.decodeStream(is);
//imageView.setImageBitmap(bitmap);
Message msg = Message.obtain();
msg.what = IMAGE_VIEW;
msg.obj = bitmap;
Log.i(Tag, "消息接收到了1。。。");
handler.sendMessage(msg);
