#FileDownloaderDemo
##1 注册用户id 启动服务
```java
//必须先注册用户id 如果没有则传值null
DownloadService.setUserid("haha");
this.startService(new Intent(this, DownloadService.class));
```

##2 添加缓存
```java
//获取downloadermanager
this.downloadManager = DownloadService.getDownloadManager();
//url:文件网络下载地址
//cachePath:文件本地缓存的路径 不能为空 绝对路径
boolean result = downloadManager.addTask(url, cachePath);
//可以自己定义文件名
addTask(String url, String cachePath, String fileName);
```

##3 获取文件的信息
```java
//获取文件名
mDownloadManager.getFileName(url);
//获取文件下载的进度
mDownloadManager.getProgress(url);
//获取文件已经下载的大小
mDownloadManager.getFileDownloadedSize(url);
//获取文件的总大小
mDownloadManager.getFileSize(url);
```

##4 切换文件下载的状态
```java
//点击item后不要考虑文件当前的状态 调用此方法即可
mDownloadManager.switchStatus(url);  
//给item添加监听 可以获取状态
mDownloadManager.setOnFileDownloadStatusListener(url, new OnFileDownloadStatusListener() {
            @Override
            public void onFileDownloadStatusWaiting(DownloadFileInfo downloadFileInfo) {
                updateProgressPartly(1,downloadFileInfo,position);
            }

            @Override
            public void onFileDownloadStatusDownloading(DownloadFileInfo downloadFileInfo) {
                Log.d(TAG,"downloadFileInfo:"+downloadFileInfo.getDownloadSize());
                updateProgressPartly(2,downloadFileInfo,position);

            }

            @Override
            public void onFileDownloadStatusPaused(DownloadFileInfo downloadFileInfo) {
                updateProgressPartly(3,downloadFileInfo,position);
            }

            @Override
            public void onFileDownloadStatusCompleted(DownloadFileInfo downloadFileInfo) {
                updateProgressPartly(4,downloadFileInfo,position);
            }

            @Override
            public void onFileDownloadStatusFailed(DownloadFileInfo downloadFileInfo) {
                updateProgressPartly(5,downloadFileInfo,position);
            }
        });
```
##5 全部下载 全部暂停 多个开始下载 多个暂停
 ```java
 //多个下载
 //传入需要开始下载的url集合 
 public void startAll(List<String> urlList)
 //多个暂停
 //传入需要暂停下载的url集合 
 public void stopAll(List<String> urlList)
