安装教程

方法一:

  1. 编译ProgressManager的har包progress-release.har。

  2. 启动 DevEco Studio,将编译的har包,导入工程目录“entry->libs”下。

  3. 在moudle级别下的build.gradle文件中添加依赖,在dependences标签中增加对libs目录下har包的引用。

    dependencies {
        implementation fileTree(dir: 'libs', include: ['*.jar', '*.har'])
        ……
    }
  4. 在导入的har包上点击右键,选择“Add as Library”对包进行引用,选择需要引用的模块,并点击“OK”即引用成功。

方法二:

  1. 在工程的build.gradle的allprojects中,添加HAR所在的Maven仓地址:
 repositories {
     maven {
         url 'http://106.15.92.248:8081/repository/Releases/'
     }
 }
  1. 在应用模块的build.gradle的dependencies闭包中,添加如下代码:
 dependencies {
     implementation 'me.jessyan.progressmanager.ohos:progress:1.0.0'
 }

使用说明

(一)下载代码

(1)初始化,设置监听

  //Okhttp/Retofit 下载监听
        ProgressManager.getInstance().addResponseListener(mDownloadUrl, getDownloadListener());

(2)下载

  /**
     * 点击开始下载资源,为了演示,就不做重复点击的处理,即允许用户在还有进度没完成的情况下,使用同一个 url 开始新的下载
     */
    private void downloadStart() {
        new Thread(() -> {
            try {
                Request request = new Request.Builder()
                        .url(mDownloadUrl)
                        .build();
                Response response = mOkHttpClient.newCall(request).execute();
                InputStream is = response.body().byteStream();
                //为了方便就不动态申请权限了,直接将文件放到CacheDir()中
                File file = new File(getCacheDir(), "download");
                FileOutputStream fos = new FileOutputStream(file);
                BufferedInputStream bis = new BufferedInputStream(is);
                byte[] buffer = new byte[1024];
                int len;
                while ((len = bis.read(buffer)) != -1) {
                    fos.write(buffer, 0, len);
                }
                fos.flush();
                fos.close();
                bis.close();
                is.close();


            } catch (IOException e) {
                e.printStackTrace();
                //当外部发生错误时,使用此方法可以通知所有监听器的 onError 方法
                ProgressManager.getInstance().notifyOnErorr(mDownloadUrl, e);
            }
        }).start();
    }

(3)下载进度变化监听


    private ProgressListener getDownloadListener() {
        return new ProgressListener() {
            @Override
            public void onProgress(ProgressInfo progressInfo) {
                // 如果你不屏蔽用户重复点击上传或下载按钮,就可能存在同一个 Url 地址,上一次的上传或下载操作都还没结束,
                // 又开始了新的上传或下载操作,那现在就需要用到 id(请求开始时的时间) 来区分正在执行的进度信息
                // 这里我就取最新的下载进度用来展示,顺便展示下 id 的用法

                if (mLastDownloadingInfo == null) {
                    mLastDownloadingInfo = progressInfo;
                }

                //因为是以请求开始时的时间作为 Id ,所以值越大,说明该请求越新
                if (progressInfo.getId() < mLastDownloadingInfo.getId()) {
                    return;
                } else if (progressInfo.getId() > mLastDownloadingInfo.getId()) {
                    mLastDownloadingInfo = progressInfo;
                }

                int progress = mLastDownloadingInfo.getPercent();
                mDownloadProgress.setProgressValue(progress);
                mDownloadProgressText.setText(progress + "%");
                LogUtils.log(LogUtils.DEBUG,TAG,  "--Download-- " + progress + " %  " + mLastDownloadingInfo.getSpeed() + " byte/s  " + mLastDownloadingInfo.toString());
                if (mLastDownloadingInfo.isFinish()) {
                    //说明已经下载完成
                     LogUtils.log(LogUtils.DEBUG,TAG,  "--Download-- finish");
                }
            }

            @Override
            public void onError(long id, Exception e) {
                mHandler.postSyncTask(new Runnable() {
                    @Override
                    public void run() {
                        mDownloadProgress.setProgressValue(0);
                        mDownloadProgressText.setText("error");
                    }
                });
            }
        };
    }

(二)上传文件

(1)上传初始化

    //Okhttp/Retofit 上传监听
        ProgressManager.getInstance().addRequestListener(mUploadUrl, getUploadListener());

(2)上传

    /**
     * 点击开始上传资源,为了演示,就不做重复点击的处理,即允许用户在还有进度没完成的情况下,使用同一个 url 开始新的上传
     */
    private void uploadStart() {
        new Thread(() -> {
            try {
                //为了方便就不动态申请权限了,直接将文件放到CacheDir()中
                File file = new File(getCacheDir(), "a.java");
                //读取Assets里面的数据,作为上传源数据
                writeToFile(getRawFile(MainAbilitySlice.this, "a.java"), file);
                Request request = new Request.Builder()
                        .url(mUploadUrl)
                        .post(RequestBody.create(MediaType.parse("multipart/form-data"), file))
                        .build();

                Response response = mOkHttpClient.newCall(request).execute();
                response.body();
            } catch (IOException e) {
                e.printStackTrace();
                //当外部发生错误时,使用此方法可以通知所有监听器的 onError 方法
                ProgressManager.getInstance().notifyOnErorr(mUploadUrl, e);
            }
        }).start();
    }

(3)上传监听变化


    private ProgressListener getUploadListener() {
        return new ProgressListener() {
            @Override
            public void onProgress(ProgressInfo progressInfo) {
                // 如果你不屏蔽用户重复点击上传或下载按钮,就可能存在同一个 Url 地址,上一次的上传或下载操作都还没结束,
                // 又开始了新的上传或下载操作,那现在就需要用到 id(请求开始时的时间) 来区分正在执行的进度信息
                // 这里我就取最新的上传进度用来展示,顺便展示下 id 的用法

                if (mLastUploadingingInfo == null) {
                    mLastUploadingingInfo = progressInfo;
                }

                //因为是以请求开始时的时间作为 Id ,所以值越大,说明该请求越新
                if (progressInfo.getId() < mLastUploadingingInfo.getId()) {
                    return;
                } else if (progressInfo.getId() > mLastUploadingingInfo.getId()) {
                    mLastUploadingingInfo = progressInfo;
                }

                int progress = mLastUploadingingInfo.getPercent();
                mUploadProgress.setProgressValue(progress);
                mUploadProgressText.setText(progress + "%");
                LogUtils.log(LogUtils.DEBUG, TAG, "--Upload-- " + progress + " %  " + mLastUploadingingInfo.getSpeed() + " byte/s  " + mLastUploadingingInfo.toString());
                if (mLastUploadingingInfo.isFinish()) {
                    //说明已经上传完成
                    LogUtils.log(LogUtils.DEBUG, TAG, "--Upload-- finish");
                }
            }

            @Override
            public void onError(long id, Exception e) {
                mHandler.postSyncTask(new Runnable() {
                    @Override
                    public void run() {
                        mUploadProgress.setProgressValue(0);
                        mUploadProgressText.setText("error");
                    }
                });
            }
        };
    }

(三)图片加载代码

(1)初始化,设置监听

mNewImageUrl = ProgressManager .getInstance().addDiffResponseListenerOnSameUrl("http://jessyancoding.github.io/images/RxCache.png", getGlideListener());

(2)加载设置


    /**
     * 点击开始 Glide 加载图片,为了演示,就不做重复点击的处理,目前这个在支持现有的ohos 的glide中,存在一些问题,无法兼容起来,
     * 做了单独处理
     */
    private void glideStart() {
        LoadPictureUtils.with(this)
                .def(ResourceTable.Media_A)
                .load(mNewImageUrl)
                .into(mImageView);
    }

(3) 图片进度加载变化监听


    private ProgressListener getGlideListener() {
        return new ProgressListener() {
            @Override
            public void onProgress(ProgressInfo progressInfo) {
                int progress = progressInfo.getPercent();
                mGlideProgress.setProgressValue(progress);
                mGlideProgressText.setText(progress + "%");
                LogUtils.log(LogUtils.DEBUG,TAG, "--Glide-- " + progress + " %  " + progressInfo.getSpeed() + " byte/s  " + progressInfo.toString());
                if (progressInfo.isFinish()) {
                    //说明已经加载完成
                }
            }

            @Override
            public void onError(long id, Exception e) {
                mHandler.postSyncTask(new Runnable() {
                    @Override
                    public void run() {
                        mGlideProgress.setProgressValue(0);
                        mGlideProgressText.setText("error");
                    }
                });
            }
        };
    }
