多线程下载是加快下载速度的一种方式，通过开启多个线程去执行一个任务，可以使任务的执行速度变快。多线程的任务下载时常都会使用得到断点续传下载，就是我们在一次下载未结束时退出下载，第二次下载时会接着第一次下载的进度继续下载。对于android中的下载，我想分多个部分去讲解分析。今天，我们就首先开始android中下载断点续传代码的实现。源码下载：java多线程断点续传(一)。关于多线程下载单个文件的实现，请参见博客：android程序---->android多线程下载(二)

android中断点续传的思路

一、 断点续传的实现步骤：

第一步： 我们要获得下载资源的的长度，用http请求中HttpURLConnection的getContentLength()方法

第二步：在本地创建一个文件，设计其长度。File file = new File()

第三步：从数据库中获得上次下载的进度，当暂停下载时，存储下载的状态，用到数据库的知识

第四步：从上次下载的位置下载数据，同时保存进度到数据库：RandomAccessFile的seek方法与HttpURLConnection的setRequestProperty方法

第五步：将下载进度回传到Activity，可以通过Intent将数据广播到Activity中

第六步：下载完成后删除下载信息，在数据库中删除相应的信息

            android:id="@+id/stop"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:text="暂停下载" />

        <Button

            android:layout_marginLeft="20dp"

            android:id="@+id/cancel"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:text="取消下载" />

    </LinearLayout>

</LinearLayout>

二、 在MainActivity中初始化一些组件，绑定按钮的事件：

在onCreate方法中初始化一些组件：

// 初始化组件

textView = (TextView) findViewById(R.id.textView);

progressView = (TextView) findViewById(R.id.progress);

speedView = (TextView) findViewById(R.id.speed);

progressBar = (ProgressBar) findViewById(R.id.progressBar);

progressBar.setMax(100);

startButton = (Button) findViewById(R.id.start);

stopButton = (Button) findViewById(R.id.stop);

cancelButton = (Button) findViewById(R.id.cancel);

// 创建一个文件信息对象

final FileInfo fileInfo = new FileInfo(0, fileUrl, "huhx.apk", 0, 0);

在onCreate方法中绑定开始下载按钮事件：点击start按钮，设置进度条可见，并且设置start的Action，启动服务。

startButton.setOnClickListener(new View.OnClickListener() {

    @Override

    public void onClick(View v) {

        textView.setText(fileInfo.getFileName());

        progressBar.setVisibility(View.VISIBLE);

        // 通过Intent传递参数给service

        Intent intent = new Intent(MainActivity.this, DownloadService.class);

        intent.setAction(DownloadService.ACTION_START);

        intent.putExtra("fileInfo", fileInfo);

        startService(intent);

    }

});

在onCreate方法中绑定暂停下载按钮事件：点击stop按钮，设置stop的Action，启动服务。

stopButton.setOnClickListener(new View.OnClickListener() {

    @Override

    public void onClick(View v) {

        // 通过Intent传递参数给service

        Intent intent = new Intent(MainActivity.this, DownloadService.class);

        intent.setAction(DownloadService.ACTION_STOP);

        intent.putExtra("fileInfo", fileInfo);

        startService(intent);

    }

});

在onCreate方法中绑定取消下载按钮事件：点击cancel按钮，设置cancel的Action，启动服务，之后更新UI。

cancelButton.setOnClickListener(new View.OnClickListener() {

    @Override

    public void onClick(View v) {

        // 通过Intent传递参数给service

        Intent intent = new Intent(MainActivity.this, DownloadService.class);

        intent.setAction(DownloadService.ACTION_CANCEL);

        intent.putExtra("fileInfo", fileInfo);

        startService(intent);

        // 更新textView和progressBar的显示UI

        textView.setText("");

        progressBar.setVisibility(View.INVISIBLE);

        progressView.setText("");

        speedView.setText("");

    }

});

注册广播，用于Service向Activity传递一些下载进度信息：

// 静态注册广播

IntentFilter intentFilter = new IntentFilter();

intentFilter.addAction(DownloadService.ACTION_UPDATE);

registerReceiver(broadcastReceiver, intentFilter);

/**

 * 更新UI

 */

BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {

    @Override

    public void onReceive(Context context, Intent intent) {

        if (DownloadService.ACTION_UPDATE.equals(intent.getAction())) {

            int finished = intent.getIntExtra("finished", 0);

            int speed = intent.getIntExtra("speed", 0);

            Log.i("Main", finished + "");

            progressBar.setProgress(finished);

            progressView.setText(finished + "%");

            speedView.setText(speed + "KB/s");

        }

    }

};

三、 在AndroidManifest.xm文件中声明权限，定义服务

<service android:name="com.huhx.services.DownloadService" android:exported="true" />

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

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

android断点续传的工具类

二、 我们定义一些实体类，用于断点续传过程的信息的良好封装：

下载文件信息： 省略了get和set方法，以及toString和构造方法

public class FileInfo implements Serializable{

    // 文件Id，用于标识文件

    private int fileId;

    // 文件的下载地址

    private String url;

    // 文件的名称

    private String fileName;

    // 文件的长度，也就是大小

    private int length;

    // 文件已经的下载量

    private int finished;

}

下载资源的线程信息：省略同上

public class ThreadInfo {

    // 线程ID

    private int threadId;

    // 下载资源的地址

    private String url;

    //下载资源的开始处

    private int start;

    //下载资源的结束处

    private int end;

    //资源已经的下载量

    private int finished;

}

三、 我们开始数据库方面的编写，它用于存储更新线程的下载的进度信息

首先我们要创建一个数据库的工具类：

package com.huhx.util;

import android.content.Context;

import android.database.sqlite.SQLiteDatabase;

import android.database.sqlite.SQLiteOpenHelper;

/**

 * Created by huhx on 2016/4/9.

 */

public class SqliteDBHelper extends SQLiteOpenHelper {

    private static final String DB_NAME = "download.db";

    private static final int version = 1;

    private static final String CREATE_THREADINFO = "create table thread_info(_id integer primary key autoincrement, " +

            "thread_id integer, url text, start integer, end integer, finished integer)";

    private static final String DROP_THREADINFO = "drop table if exists thread_info";

    public SqliteDBHelper(Context context) {

        super(context, DB_NAME, null, version);

    }

    @Override

    public void onCreate(SQLiteDatabase db) {

        db.execSQL(CREATE_THREADINFO);

    }

    @Override

    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {

        db.execSQL(DROP_THREADINFO);

        db.execSQL(CREATE_THREADINFO);

    }

}

定义一个Dao接口，用于数据库对线程信息的CRUD操作：

/**

 * Created by Linux on 2016/4/9.

 */

public interface ThreadDao {

    // 插入线程信息

    public void insertThread(ThreadInfo threadInfo);

    // 删除线程信息

    public void deleteThread(String url, int threadId);

    // 删除所有关于这个url的线程

    public void deleteThread(String url);

    // 更新线程信息

    public void updateThread(String url, int threadId, int finished);

    // 查询线程信息

    public List<ThreadInfo> queryThread(String url);

    // 线程信息是否存在

    public boolean isThreadInfoExist(String url, int threadId);

}

具体实现上述Dao的Impl类：

package com.huhx.util;

import android.content.Context;

import android.database.Cursor;

import android.database.sqlite.SQLiteDatabase;

import com.huhx.model.ThreadInfo;

import java.util.ArrayList;

import java.util.List;

/**

 * Created by huhx on 2016/4/9.

 */

public class ThreadDaoImpl implements ThreadDao {

    private SqliteDBHelper sqliteDBHelper;

    public ThreadDaoImpl(Context context) {

        sqliteDBHelper = new SqliteDBHelper(context);

    }

    @Override

    public void insertThread(ThreadInfo threadInfo) {

        SQLiteDatabase database = sqliteDBHelper.getWritableDatabase();

        Object[] objects = new Object[]{

                threadInfo.getThreadId(), threadInfo.getUrl(), threadInfo.getStart(), threadInfo.getEnd(), threadInfo.getFinished()

        };

        database.execSQL("insert into thread_info(thread_id, url, start, end, finished) values(?,?,?,?,?)", objects);

        database.close();

    }

    @Override

    public void deleteThread(String url, int threadId) {

        SQLiteDatabase database = sqliteDBHelper.getWritableDatabase();

        Object[] objects = new Object[]{

                url, threadId

        };

        database.execSQL("delete from thread_info where url = ? and thread_id = ?", objects);

        database.close();

    }

    @Override

    public void deleteThread(String url) {

        SQLiteDatabase database = sqliteDBHelper.getWritableDatabase();

        Object[] objects = new Object[]{

                url

        };

        database.execSQL("delete from thread_info where url = ?", objects);

        database.close();

    }

    @Override

    public void updateThread(String url, int threadId, int finished) {

        SQLiteDatabase database = sqliteDBHelper.getWritableDatabase();

        Object[] objects = new Object[]{

                finished, url, threadId

        };

        database.execSQL("update thread_info set finished = ? where url = ? and thread_id = ?", objects);

        database.close();

    }

    @Override

    public List<ThreadInfo> queryThread(String url) {

        SQLiteDatabase database = sqliteDBHelper.getWritableDatabase();

        List<ThreadInfo> threadInfos = new ArrayList<>();

        Cursor cursor = database.rawQuery("select * from thread_info where url = ?", new String[]{url});

        while (cursor.moveToNext()) {

            ThreadInfo threadInfo = new ThreadInfo();

            threadInfo.setThreadId(cursor.getInt(cursor.getColumnIndex("thread_id")));

            threadInfo.setUrl(cursor.getString(cursor.getColumnIndex("url")));

            threadInfo.setStart(cursor.getInt(cursor.getColumnIndex("start")));

            threadInfo.setEnd(cursor.getInt(cursor.getColumnIndex("end")));

            threadInfo.setFinished(cursor.getInt(cursor.getColumnIndex("finished")));

            threadInfos.add(threadInfo);

        }

        cursor.close();

        database.close();

        return threadInfos;

    }

    @Override

    public boolean isThreadInfoExist(String url, int threadId) {

        SQLiteDatabase database = sqliteDBHelper.getWritableDatabase();

        Cursor cursor = database.rawQuery("select * from thread_info where url = ? and thread_id = ?", new String[]{url, threadId+""});

        boolean isExist = cursor.moveToNext();

        cursor.close();

        database.close();

        return isExist;

    }

}

下载暂停取消的具体流程

四、 最后我们开始最重要的Service以及核心的下载代码的编写，我们按照上述的开始、暂停、取消的顺序，来讲解断点续传的实现过程。

我们在DownloadService中onStartCommand方法中接收的Intent，关于Service的使用请参见：android基础---->service的生命周期

@Override

public int onStartCommand(Intent intent, int flags, int startId) {

    // 获得Activity传过来的参数

    if (ACTION_START.equals(intent.getAction())) {

        FileInfo fileInfo = (FileInfo) intent.getSerializableExtra("fileInfo");

        // 启动初始化线程

        new InitThread(fileInfo).start();

    } else if (ACTION_STOP.equals(intent.getAction())) {

        FileInfo fileInfo = (FileInfo) intent.getSerializableExtra("fileInfo");

        if (downloadTask != null) {

            downloadTask.isPause = true;

        }

    } else if (ACTION_CANCEL.equals(intent.getAction())) {

        FileInfo fileInfo = (FileInfo) intent.getSerializableExtra("fileInfo");

        if (downloadTask != null) {

            downloadTask.isPause = true;

        }

        // 删除本地文件

        File file = new File(DOWNLOAD_PATH, fileInfo.getFileName());

        if (file.exists()) {

            file.delete();

        }

        handler.obtainMessage(DOWNLOAD_CANCEL, fileInfo).sendToTarget();

    }

    return super.onStartCommand(intent, flags, startId);

}

五、 文件的开始下载流程：

开始下载时，启动一个初始化线程，并把文件信息传递给线程，该线程通过Http请求得到文件的长度，在本地创建下载文件的载体，设置大小并发送下载的消息给Handler：

/**

 * 初始化子线程

 */

class InitThread extends Thread {

    private FileInfo fileInfo = null;

    public InitThread(FileInfo fileInfo) {

        this.fileInfo = fileInfo;

    }

    @Override

    public void run() {

        // 连接网络文件

        HttpURLConnection connection = null;

        RandomAccessFile randomAccessFile = null;

        try {

            URL url = new URL(fileInfo.getUrl());

            connection = (HttpURLConnection) url.openConnection();

            connection.setConnectTimeout(3000);

            connection.setRequestMethod("GET");

            connection.connect();

            int length = -1;

            if (connection.getResponseCode() == HttpURLConnection.HTTP_OK) {

                // 获取文件的长度

                length = connection.getContentLength();

            }

            if (length <= 0) {

                return;

            }

            // 在本地创建文件

            File dir = new File(DOWNLOAD_PATH);

            if (dir.exists()) {

                dir.mkdir();

            }

            File file = new File(dir, fileInfo.getFileName());

            // 设置文件长度

            randomAccessFile = new RandomAccessFile(file, "rwd");

            randomAccessFile.setLength(length);

            fileInfo.setLength(length);

            handler.obtainMessage(DOWNLOAD_MESSAGE, fileInfo).sendToTarget();

        } catch (Exception e) {

            e.printStackTrace();

        } finally {

            try {

                randomAccessFile.close();

                connection.disconnect();

            } catch (IOException e) {

                e.printStackTrace();

            }

        }

    }

}

handler接收消息，并加以处理：注意这里有两种消息，我们暂时只考虑DOWNLOAD_MESSAGE消息，它启动下载任务

private Handler handler = new Handler() {

    @Override

    public void handleMessage(Message msg) {

        switch (msg.what) {

            case DOWNLOAD_MESSAGE:

                FileInfo fileInfo = (FileInfo) msg.obj;

                // 启动下载任务

                downloadTask = new DownloadTask(DownloadService.this, fileInfo);

                downloadTask.download();

                break;

            case DOWNLOAD_CANCEL:

                FileInfo fileCancelInfo = (FileInfo) msg.obj;

                downloadTask = new DownloadTask(DownloadService.this);

                downloadTask.cancelDownload(fileCancelInfo);

                break;

        }

    }

};

在download方法中，首先判断是否有线程下载过文件，如果没有就创建一个。有的话，从数据库直接得到。而且开启了下载的任务线程

public void download() {

    // 读取数据库的线程信息

    List<ThreadInfo> threadInfos = threadDao.queryThread(fileInfo.getUrl());

    ThreadInfo threadInfo = null;

    if (threadInfos.size() == 0) {

        threadInfo = new ThreadInfo(0, fileInfo.getUrl(), 0, fileInfo.getLength(), 0);

    } else {

        threadInfo = threadInfos.get(0);

    }

    new DownloadThread(threadInfo).start();

}

在下载的线程中，通过Http请求数据并通过字节流的方式存储在本地的文件中。间隔500毫秒，就发送一次更新UI的广播。如果收到了暂停的信号，就暂停下载。在下载完成之后，删除数据库中的线程信息

class DownloadThread extends Thread {

    private ThreadInfo threadInfo = null;

    public DownloadThread(ThreadInfo threadInfo) {

        this.threadInfo = threadInfo;

    }

    @Override

    public void run() {

        // 向数据库插入线程信息

        if (!threadDao.isThreadInfoExist(threadInfo.getUrl(), threadInfo.getThreadId())) {

            threadDao.insertThread(threadInfo);

        }

        HttpURLConnection connection = null;

        RandomAccessFile randomAccessFile = null;

        InputStream inputStream = null;

        try {

            URL url = new URL(threadInfo.getUrl());

            connection = (HttpURLConnection) url.openConnection();

            connection.setConnectTimeout(5000);

            connection.setRequestMethod("GET");

            int start = threadInfo.getStart() + threadInfo.getFinished();

            connection.setRequestProperty("Range", "bytes=" + start + "-" + threadInfo.getEnd());

            File file = new File(DownloadService.DOWNLOAD_PATH, fileInfo.getFileName());

            randomAccessFile = new RandomAccessFile(file, "rwd");

            randomAccessFile.seek(start);

            Intent intent = new Intent(DownloadService.ACTION_UPDATE);

            // 开始下载

            finished += threadInfo.getFinished();

            if (connection.getResponseCode() == HttpURLConnection.HTTP_PARTIAL) {

                inputStream = connection.getInputStream();

                byte[] buffer = new byte[4 * 1024];

                int len = -1;

                long time = System.currentTimeMillis();

                long time1;

                while ((len = inputStream.read(buffer)) != -1) {

                    randomAccessFile.write(buffer, 0, len);

                    finished += len;

                    if ((time1 = System.currentTimeMillis() - time) > 500) {

                        time = System.currentTimeMillis();

                        intent.putExtra("finished", finished * 100 / fileInfo.getLength());

                        intent.putExtra("speed", (int) (len / time1));

                        context.sendBroadcast(intent);

                    }

                    if (isPause) {

                        threadDao.updateThread(threadInfo.getUrl(), threadInfo.getThreadId(), finished);

                        return;

                    }

                }

                // 删除线程信息,再次发送广播避免上面的广播延迟

                intent.putExtra("finished", finished * 100 / fileInfo.getLength());

                context.sendBroadcast(intent);

                threadDao.deleteThread(threadInfo.getUrl(), threadInfo.getThreadId());

                Log.i("Main", "finished: " + finished + ", and file length: " + fileInfo.getLength());

            }

        } catch (Exception e) {

            e.printStackTrace();

        } finally {

            try {

                connection.disconnect();

                randomAccessFile.close();

                inputStream.close();

            } catch (IOException e) {

                e.printStackTrace();

            }

        }

    }

}

六、 文件的暂停下载流程：如果下载任务在启动，那么设置isPause为true，在上述的讲解中我们知道，此时字节流停止的传输。

if (downloadTask != null) {

    downloadTask.isPause = true;

}

七、 文件的取消下载流程：

暂停下载的流程，然后删除本地文件，最后发送取消下载的消息：

FileInfo fileInfo = (FileInfo) intent.getSerializableExtra("fileInfo");

if (downloadTask != null) {

    downloadTask.isPause = true;

}

// 删除本地文件

File file = new File(DOWNLOAD_PATH, fileInfo.getFileName());

if (file.exists()) {

    file.delete();

}

handler.obtainMessage(DOWNLOAD_CANCEL, fileInfo).sendToTarget();

handler处理取消下载的消息：调用DownloadTask的cancelDownload方法，并把文件信息传入

case DOWNLOAD_CANCEL:

        FileInfo fileCancelInfo = (FileInfo) msg.obj;

        downloadTask = new DownloadTask(DownloadService.this);

        downloadTask.cancelDownload(fileCancelInfo);

        break;

在cancelDownload方法中删除数据库中的线程信息：

// 取消下载任务

public void cancelDownload(FileInfo fileInfo) {

    threadDao.deleteThread(fileInfo.getUrl());

}

最后在MainActivity中更新UI：

// 更新textView和progressBar的显示UI

textView.setText("");

progressBar.setVisibility(View.INVISIBLE);

progressView.setText("");

speedView.setText("");
