Activity

public class MainActivity extends AppCompatActivity {

    private SketchImageView image;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        findViews();
        initViews();
    }

    private void findViews() {
        setContentView(R.layout.activity_main);
        image = (SketchImageView) findViewById(R.id.image);
    }

    private void initViews() {
        image.displayImage("http://appcdn.0315.cn/Uploads/20161022/580b173f378e4.jpg");
        image.setSupportZoom(true);
        image.setSupportLargeImage(true);
        ImageZoomer imageZoomer = image.getImageZoomer();
        imageZoomer.setReadMode(true);
    }
}

layout

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="cn.iec_ts.test.MainActivity">

    <me.xiaopan.sketch.SketchImageView
        android:id="@+id/image"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</RelativeLayout>

效果如下

是不是小的有啥东西没写，为啥我加载出来的长图没有分块，模模糊糊的，是不是什么地方配置错了？

我现在需要实现这样一个功能，在一个gif播放完以后播放另一个git，我在前一个gif的onComplete方法中调用播放第二个gif的代码，但是两个gif并没有实现先后播放，而是同时播放。多谢楼主！

可以设置宽高比来显示图片吗

您好，有的图片为什么不会缓存的，我看您的demo里面的明星图片可以缓存，我替换了几个图片url，断网以后，我替换的图片被清除了，其他的图片正常从diskcache展示了

近日加入新的工作组，图片加载方面用到了你的Sketch，我想用它的本意是支持Gif和图片加工等原因。不过在使用中，我遇到了如下问题。当我图片URL的地址不可用时，图片列表页面就会展示默认图，这没有问题。但是，假设点击图片Item进入到详情再返回至本页时默认图片就会很神奇的缩小到左上角一块。可能点击一张默认图片Item不会复现，可是多点击几个Item就会出现如上问题。如果您有空，请不吝解答一下。我的猜测是当加载默认图片drawable时，当加载多张旧图（缓存）时scaleType的设置有问题。谢谢。

大图滑动、放大、缩小... 一些列操作后 （放大状态）会不响应滑动，点击设置并关闭对话框后可以；这时候双击缩小也可以

printLogE("loadCompleted", "decode failed", "bitmap recycled", "bitmapInfo: " + 错误在loadResult.getGifDrawable().getInfo());

应该是
printLogE("loadCompleted", "decode failed", "bitmap recycled", "bitmapInfo: " + RecycleBitmapDrawable.getInfo(loadResult.getBitmap(), loadResult.getMimeType()));

Can't play gif image of drawable in imageView

举例：在Unsplash这个界面点击其中一张图进入单张浏览页面，一共有20张图，从第一张滑动到最后一张，APP占用内存增加了35兆以上（进入APP时占用31.31M,滑动完成后占用67.51M），在退出该Activity的时候不释放内存。其他的的页面看图片也是这样的

2.3.0beta1已修复

你好，我在使用本框架的时候，有用到 base64 加载图片，在使用中，发现文档有一处写错了，还请查看下是否存在此问题。
文档描述：
// display base64 image
sketchImageView.displayImage("data:image/jpeg;base,/9j/4QaO...U7T/in//Z");

源码中调用方式：
UriScheme 第 127 行：
return uri.substring(uri.indexOf(";") + ";base64,".length());

我目前使用方式，可以正确显示图片：
imageView.displayImage("data:image/jpeg;" + ";base64," + data.getImage());

如果用户调用文档的方式，控制台会显示 base64 解码错误，会让用户产生一个小误解，以为是 图片错误。请查看是否存在这个问题o(￣︶￣)o

在开启手势缩放之后在列表中滑动的时候，划过几张图片之后手势缩放失效，并且在处于图片被手动缩小了之后再滑动过几张图片之后会导致所有图片都缩小了，然后手势缩放还失效了，就变不会来了，这是什么原因啊？我在列表中不开手势缩放到还没感觉出上面的问题

hi xiaopansky:
你的这个库非常好，但是我现在有一个问题，就是在加载图片的时候需要指定一个User-Agent， 我看了下你的文档好像是不支持。能否开放相关接口？

Hi,
I want to have more zoom in SketchImageView
I'm doing the code below but zoom doesn't change to 20f, but remain the default zoom

val photoView = SketchImageView(container.context)
photoView.isZoomEnabled = true
photoView.imageZoomer.zoom(20f)
photoView.options.setImageDisplayer(FadeInImageDisplayer())
photoView.displayImage("http://www.examplelink.com/example.jpg")

大佬有请求图片设置Header实现防盗链的案例吗

How to find out image orientation which is taken from default camera.

menu --- myphotos -- the third gif -- CRASH
my phone is HUAWEI Honor 8 lite base on Android 7.0

非常棒的图片加载库,但是看了下网络请求图片层用的是HttpClient实现的,考虑到Android后续已经不支持HttpClient,可否替换为其他类似okHTTP之类的加载;另外一个问题是,在加载gif动图的时候例如在列表中加载gif,并且设置都能动的情况,可否实现滚出屏幕之后动图能暂停,用户可见的时候,在继续播放这样的功能呢?

Android本身ImageView支持的ScaleType比较局限,是否考虑能增加更多的scaleType方式呢?例如:CropImageView 如此感觉SketchImageView就更棒了:)

这个链接失效了

你好，很喜欢这个库,使用过程中容易出现下面这个错误
java.lang.IllegalArgumentException: pointerIndex out of range pointerIndex=-1 pointerCount=1

怎么办

Hi,

Can you please add options for (share and set wallpaper)

thanks for great app

Sketch.with(context).download或者load方法拿到的result如何在SketchImageView中展示，示例只是说要先下载后加载，但是没有找到下载后怎么展示，多谢答主。

如题，请问这个有现成的实现方案嘛？

Hi,

First of all, thank you for the amazing library! I implemented it in my photoalbum app, it is working great now!

I have a suggestion for this library: Are you thinking of adding a zooming feature? I found this nice library - Scale Image View on Github for zooming images. What do you think?

Hi,
Can you add an example how to use sketch with PhotoView inside a ViewPager on your README.md ?

我只想单独暂停下载一张图片怎么办，比如我检测到一张图片非常大

1. 如示例里面的地图和黑圈，放大后，在部分切块交接边沿有空白线(有的手机看起来像黑线，有的手机看起来是透明的线，显示底下模糊背景)（看起来像是切片小了一个像素，放大到最大，或者缩小到最小就没有线）

2. 示例里的微博长度，每块切片的加载时间，会越来越长，不断上下滑动，每次切片的时间会递增

两张gif图片切换，一张为放大状态，会卡在切换过程中

怎么显示网络Gif图片啊？加载出来只有第一帧？

代码是这样设置的

@Override
         public Object instantiateItem(ViewGroup view, final int position) {
            final SketchImageView imageView = new SketchImageView(browseImageActivity);
            imageView.setSupportLargeImage(true);
            imageView.setSupportZoom(true);
            imageView.displayImage(list.get(position));

            ViewGroup.LayoutParams layoutParams = new ViewPager.LayoutParams();
            view.addView(imageView, layoutParams);

            ImageZoomer zoomer = imageView.getImageZoomer();
            zoomer.setReadMode(true);
            zoomer.setOnViewLongPressListener(new ImageZoomer.OnViewLongPressListener() {
                @Override
                public void onViewLongPress(View view, float x, float y) {
                    browseImageActivity.popWindow.showAtLocation(LayoutInflater.from(browseImageActivity).inflate(R.layout.activity_main, null), Gravity.CENTER, 0, 0);
                }
            });

            return imageView;
        }
