高仿微信可拖拽返回PhotoView

### 基于 [PhotoView](https://github.com/chrisbanes/PhotoView)

##[下载APK体验](https://github.com/githubwing/DragPhotoView/raw/master/app-debug.apk)

## 特性

- 拖拽缩放图片,并且结束Activity

- 其他PhotoView所有特性如下:

>- Out of the box zooming, using multi-touch and double-tap.

>- Scrolling, with smooth scrolling fling.

>- Works perfectly when used in a scrolling parent (such as ViewPager).

>- Allows the application to be notified when the displayed Matrix has changed. Useful for when you need to update your UI based on the >current zoom/scroll position.

>- Allows the application to be notified when the user taps on the Photo.

# 使用

修改你的  `build.gradle`文件

```gradle

//root project

allprojects {

		repositories {

			...

			maven { url 'https://jitpack.io' }

		}

	}

    

//module project

    	dependencies {

	        compile 'com.github.githubwing:DragPhotoView:1.0.1'

	}

    

```

使用法放和普通的ImageView一毛一样

```java

	// 所有ImageView用法都可以	

	DragPhotoView photoView = (DragPhotoView)findViewById(R.id.photoView);

	photoView.setImageResource(R.drawable.ram);

	//必须添加一个onExitListener,在拖拽到底部时触发.	

	photoView.setOnExitListener()

	

	photoView.setOnTapListener()

```

## 小贴士

想要达到demo效果,需要把你的Activity背景改为透明

修改`style.xml`

```xml

  

        <item name="android:windowBackground" >@android:color/transparent</item>

        <item name="android:windowIsTranslucent">true</item>

    

```

全版本共享元素实现(包括Activity转跳和拖拽共享元素)在Demo里,如有需要,参照demo思路实现即可.
