原创 Android多线程断点下载jar包使用

工作闲余时上网查了一番Android多线程断点下载的资料，大多数方式都是将整个文件分段然后再分给几个线程进行下载，这里个人觉着分块下载最后整合的方式速度尚可，经过整合后一个download-manager.jar。使用方法：1.布局文件：<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

原创自己封装的Android sqlite-helper.jar包使用方法

在Android项目开发中会经常使用到其内嵌的SQLite数据库，但是疲于Android本身的SQLiteOpenHelper的繁琐（也许个人从事过Web开发，惯用MySql的偏见），经过统一思想的方式封装了该sqlite-helper.jar包，对于从Java Web方向转过来的人也许算是一种帮助吧！1.新建实体类package com.whl.helper.entity;im

根据网上寻找的资料，加上自己的整合，打包的一个Android多线程下载。可以实现断点下载，暂停继续取消下载，能够显示现在已完成大小，文件大小，完成度，下载速度等。使用方法如下： public class MainActivity extends Activity implements OnClickListener,DownloadListener{ private static final String TAG = "MainActivity"; private static final String SD_PATH = Environment.getExternalStorageDirectory().getPath(); private boolean isPause = false; private MultiThreadDownload multiThreadDownload ; private Button buttonDownload; private Button buttonCancel; private TextProgressBar progressBarTest;//可以使用普通的进度，该进度条是可以显示现在完成度 private TextView textInfo; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main);//布局文件就是两个简单的按钮一个用于暂停继续下载，一个用于取消任务，还有一个文本用于显示已完成，文件大小，下载完成度，下载速度等信息以及一个进度条。 //http://d1.apk8.com:8020/game/plantsvszombies2.apk buttonDownload = (Button)findViewById(R.id.buttonDownload); buttonDownload.setText("单击下载"); buttonDownload.setOnClickListener(this); progressBarTest = (TextProgressBar) findViewById(R.id.progressBarTest); textInfo = (TextView) findViewById(R.id.textInfo); buttonCancel = (Button) findViewById(R.id.buttonCancel); buttonCancel.setOnClickListener(this); } @Override public void onClick(View v) { String downloadUrl = "http://dldir1.qq.com/invc/qqpinyin/QQInput4.1_1133(1001).apk"; String savePath = SD_PATH+File.separator+"downloadHelper"+File.separator; String fileName = "QQInput.apk"; switch(v.getId()){ case R.id.buttonDownload: if(!isPause){ multiThreadDownload = new MultiThreadDownload(MainActivity.this,downloadUrl, savePath, fileName, this); multiThreadDownload.start(); buttonDownload.setText("下载..."); isPause = true; }else{ buttonDownload.setText("暂停..."); isPause = false; multiThreadDownload.onPause(); multiThreadDownload = null; } break; case R.id.buttonCancel: if(multiThreadDownload==null){ multiThreadDownload = new MultiThreadDownload(MainActivity.this,downloadUrl, savePath, fileName, this); } Log.d(TAG, ""+multiThreadDownload.isDownload()); if(multiThreadDownload.isDownload()){ multiThreadDownload.onCancel(); isPause = false; } multiThreadDownload = null; break; } } private Handler multiHandler = new Handler(){ @Override public void handleMessage(Message msg) { super.handleMessage(msg); if(msg.what==1){ Bundle data = msg.getData(); float downloadSpeed = data.getFloat("downloadSpeed"); boolean speedHigh = false; if(downloadSpeed>500){ speedHigh = true; downloadSpeed/=1024; } progressBarTest.setProgress(data.getInt("completedSize")); textInfo.setText(String.format("已完成：%.2fMB", data.getInt("completedSize")/1024f/1024)+"/"+ String.format("总大小：%.2fMB", data.getInt("fileSize")/1024f/1024)+"\n"+ String.format("进度：%.2f%%", data.getBoolean("isCompleted")?100.00:data.getFloat("downloadPercent"))+"/"+ String.format(speedHigh?"速度：%.2fM/S":"速度：%.2fKB/S", downloadSpeed)); if(data.getBoolean("isCompleted")){ buttonDownload.setText("下载完成"); textInfo.setText("下载完成"); } } } }; @Override public void onDownloading(boolean isCompleted,boolean isPause,boolean isCancel,int fileSize,int completedSize,int downloadedSize,float downloadPercent, float downloadSpeed) { Log.d("MainActivity", isCompleted+"||"+isPause+"||"+completedSize+"||"+downloadedSize+"||"+downloadPercent+"||"+downloadSpeed); Message message = Message.obtain(); message.what = 1; Bundle data = new Bundle(); data.putBoolean("isCancel", isCancel); data.putBoolean("isCompleted", isCompleted); data.putInt("fileSize", fileSize); data.putInt("completedSize", completedSize); data.putInt("downloadedSize", downloadedSize); data.putFloat("downloadPercent", downloadPercent); data.putFloat("downloadSpeed", downloadSpeed); message.setData(data); multiHandler.sendMessage(message); } @Override public void onBeforeDownload(boolean isCompleted,boolean isPause,boolean isCancel,int fileSize){ progressBarTest.setMax(fileSize); } @Override public void onAfterDownload(boolean isCompleted,boolean isPause,boolean isCancel,int fileSize){ } @Override public void onPause(boolean isCompelted,boolean isPause,boolean isCancel,int fileSize,int completedSize,int downloadedSize,float downloadPercent,float downloadSpeed){ textInfo.setText("暂停..."); Log.d(TAG, "暂停..."); } @Override public void onCancelDownload(){ progressBarTest.setProgress(0); textInfo.setText("下载取消"); buttonDownload.setText("重新下载"); } }
