如何在毕加索提高速度 [英] How to increase speed in Picasso

问题描述

我正在使用Picasso加载图像，缩放并设置为listview项目.有我的代码:

I'm using Picasso to load images, scale and set to listview item. There is my code:

Picasso.with(getActivity()).load(builder.toString())
                            .config(Bitmap.Config.RGB_565)
                            .into(new Target() {
                                @Override
                                public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
                                    int width = Double.valueOf(bitmap.getWidth() * 0.75).intValue();
                                    int height = bitmap.getHeight();
                                    Bitmap newBitmap = Bitmap.createBitmap(bitmap, 0, 0, width, height);
                                    imageView.setImageBitmap(newBitmap);

                                }

                                @Override
                                public void onBitmapFailed(Drawable errorDrawable) {

                                }

                                @Override
                                public void onPrepareLoad(Drawable placeHolderDrawable) {

                                }
                    });

当我在.into()方法中创建new Target()对象时出现了问题，在此之前，加载的图像的速度非常快. 我以为到底是什么因素拖慢了我的工作，以及如何纠正它?规模内存昂贵吗?还是因为完全使用new Target()?

The problem appears when I made new Target() object in the .into() method, before that the speed of loaded images were very fast. I thought what exactly slowed down my work and how to correct it? Is scale memory-expensive or this is because of new Target() implementation at all?

谁遇到这个问题?怎么解决呢?

Who faced with this problem? How to solve that?

推荐答案

您可以使用Fresco进行图像加载..即使是Facebook，也可以使用Fresco进行缩放；您可以使用android:scaleType.its非常有用. 了解壁画 http://frescolib.org/docs/index.html

You can use Fresco for image loading..even facebook using same and for scaling you can use android:scaleType.its very usefull Read about Fresco http://frescolib.org/docs/index.html
