通过okhttpclient3下载多种网络图片后，写入viewpager imageview中后，显示顺序不对。

public Object instantiateItem(@NonNull ViewGroup container, final int position) {

imageView = new ImageView(context);

imageView.setScaleType(ImageView.ScaleType.FIT_XY);

container.addView(imageView);

NewsCenterDetailBean.DataEntity.TopNewsEntity topNewsEntity = topnews.get(position);

String imageurl = Constants.BASE_URL + topNewsEntity.getTopimage();

request = new Request.Builder().url(imageurl).build();

call = client.newCall(request);

call.enqueue(new Callback() {

@Override

public void onFailure(Call call, IOException e) {

}

@Override

public void onResponse(Call call, Response response) throws IOException {

byte[] picture = response.body().bytes();

Bitmap map = BitmapFactory.decodeByteArray(picture,0,picture.length);

Message msg = new Message();

msg.what = 0;

msg.obj = map;

handler.sendMessage(msg);

}

});

return imageView;

}

private Handler handler = new Handler() {

@Override

public void handleMessage(Message msg) {

super.handleMessage(msg);

switch (msg.what) {

case 0:

topnewsBitmap = (Bitmap) msg.obj;

imageView.setImageBitmap(topnewsBitmap);
