## 安装

> 快速安装

`$ npm install react-native-save-image --save`

`$ react-native link react-native-save-image` or `rnpm link react-native-save-image`

1. 修改 `android/settings.gradle`，添加如下的代码：

```

    	include ':react-native-save-image'   

	project(':react-native-save-image').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-save-image/android')

```

2. 修改 `android/app/build.gradle file`

```

	...

	dependencies {

	    ...

	    compile project(':react-native-splash-screen')

	}

```

3. 修改 `MainApplication.java `

```

    import com.widuu.SaveImagePackage; // 顶部导入

    @Override

    protected List getPackages() {

      return Arrays.asList(

          new MainReactPackage(),

          new SaveImagePackage(), // 这里添加

      );

    }

```

## 使用

```

	import SaveImage from 'react-native-save-image';

	export default class SaveImage extends React.Component {

	    componentDidMount() {

	    	SaveImage.setAlbumName('相册文件夹名称');

    		SaveImage.setCompressQuality(80); // 整数品质

	    }

	    render(){

	    	return(

		    

		        SaveImage.downloadImage(图片地址)}>

		 	    

              		

            	    

	    	);

	    }

	}

```

## API

    SaveImage.setCompressQuality(int compressQuality);     // 整数品质

    SaveImage.downloadImage(String Url);  	           // 图片地址,例如 http://www.baidu.com/logo.png
