Android 安卓将网络图片保存到相册

Android 安卓将网络图片保存到相册

封装了一个工具类！

请先加上读写权限:

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

如果是Android6.0之后，加上权限后再动态申请权限

if (Build.VERSION.SDK_INT > Build.VERSION_CODES.LOLLIPOP) {
	if (ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
		ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
	}
}

使用方法：

//示例1：保存网络图片
SaveNetPhotoUtils.savePhoto(this, "https://profile.csdnimg.cn/5/F/3/3_qq_40881680");

//示例2：保存网络图片并且给图片命名
SaveNetPhotoUtils.savePhoto(this, "https://profile.csdnimg.cn/5/F/3/3_qq_40881680", "photoName.jpg");

该类所带工具：

SaveNetPhotoUtils.savePhoto(上下文, 网络图片url);
SaveNetPhotoUtils.savePhoto(上下文, 网络图片url, 图片名字 + 后缀);
