如何使用Android集成腾讯X5实现文档浏览功能

这篇文章主要介绍了如何使用Android集成腾讯X5实现文档浏览功能，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。

一、下载腾讯X5内核

1.前往https://x5.tencent.com/下载Android的内核，新版本的腾讯X5可以直接在bulid.gradle集成 api 'com.tencent.tbs.tbssdk:sdk:43697'，如果是在App里集成可以把api换成implementation

2.AndroidStudio导入腾讯X5

a.把下载好的jar包导入libs，然后run as，再把jnilibs导入main包下

b. module的build.gradle添加cpu适配

3.Application中腾讯X5初始化,在onCreate()方法调用init方法

QbSdk.initX5Environment(this, new QbSdk.PreInitCallback() {   @Override   public void onCoreInitFinished() {   }   @Override   public void onViewInitFinished(boolean b) {    Log.e("xxx","hasLoad"+b);   //此处将内核加载是否成功的状态保存到本地，SharePreference工具类可换为自己的    SharedPreferenceUtils.saveBoolean(getApplicationContext(),"hasLoad",b);   }  });

4.应用内调用，无论是否加载内核，都是把在线的文档下载到本地然后打开，不同的是，未加载内核会借助QQ浏览器或其他App的文件浏览功能类似微信（这个调用，腾讯X5已自动处理，我们无需关心），而加载内核后，使用X5的TbsReaderView来打开文件，接下来就是具体代码。

a.bulid.gradle中集成Retrofit，RxJava和进度管理器ProgressManager

implementation 'io.reactivex:rxandroid:1.2.1' implementation 'com.squareup.retrofit2:converter-gson:2.3.0' implementation 'com.squareup.retrofit2:adapter-rxjava:2.1.0' implementation 'com.squareup.retrofit2:retrofit:2.3.0' implementation 'io.reactivex:rxjava:1.2.6' implementation 'me.jessyan:progressmanager:1.5.0'

写网络下载工具

public interface LoadFileApi { @GET Call<ResponseBody> loadPdfFile(@Url String fileUrl);}public class LoadFileModel { //使用该方法来下载文件 public static void loadPdfFile(String url, Callback<ResponseBody> callback) {  Retrofit retrofit = new Retrofit.Builder()    .baseUrl("https://www.baidu.com/")    .client(ProgressManager.getInstance().with(new OkHttpClient.Builder())      .build())    .addConverterFactory(GsonConverterFactory.create())    .build();  LoadFileApi mLoadFileApi = retrofit.create(LoadFileApi.class);  if (!TextUtils.isEmpty(url)) {   Call<ResponseBody> call = mLoadFileApi.loadPdfFile(url);   call.enqueue(callback);  } }}

b.具体调用

首先注册文件进度下载监听

private ProgressDialog commonProgressDialog;//切换为自己的进度控件 private ProgressInfo mLastDownloadingInfo; ProgressManager.getInstance().addResponseListener(url, new ProgressListener() {            @Override            public void onProgress(ProgressInfo progressInfo) {             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();             commonProgressDialog.setProgress(progress);             Log.d("xxx", "--Download-- " + progress + " % " + mLastDownloadingInfo.getSpeed() + " byte/s " + mLastDownloadingInfo.toString());             if (mLastDownloadingInfo.isFinish()) {              //说明已经下载完成              commonProgressDialog.dismiss();              Log.d("xxx", "--Download-- finish");             }            }            @Override            public void onError(long id, Exception e) {             e.printStackTrace();             new Handler().post(new Runnable() {              @Override              public void run() {                commonProgressDialog.dismiss();              }             });            }           });          }

然后打开文件

private static final String DOWN_DIR = Environment.getExternalStorageDirectory()   + File.separator+"Download"; //文件下载的路径，可以自定义//打开文件 private void openFile(String filePath,String fileName) {  boolean hasLoad = SharedPreferenceUtils.getBoolean(mContext, "hasLoad");//是否记载内核  if (hasLoad){  //展示文件的Activity   Intent intentDoc = new Intent(this,FileDisplayActivity.class);   intentDoc.putExtra("path",filePath);   intentDoc.putExtra("fileName",fileName);   startActivity(intentDoc);  }else {   if(!Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)){    Toast.makeText(this,"当前SD不可用",Toast.LENGTH_LONG).show();    return;   }   try {    File file = new File(DOWN_DIR, fileName);    if (file.exists()){     QbSdk.openFileReader(this, file.getAbsolutePath(), null, new ValueCallback<String>() {      @Override      public void onReceiveValue(String s) {       Log.e("xxx",s);      }     });    } else {     downLoadFile(filePath,fileName);    }   } catch (Exception e) {    e.printStackTrace();    ToastUtils.showShortToast(mContext, "已下载过了");   }  } } private void downLoadFile(final String url, final String fileName) {  commonProgressDialog.show();  LoadFileModel.loadPdfFile(url, new Callback<ResponseBody>() {   @Override   public void onResponse(@NonNull Call<ResponseBody> call, @NonNull Response<ResponseBody> response) {    InputStream is = null;    byte[] buf = new byte[2048];    int len;    FileOutputStream fos = null;    try {     ResponseBody responseBody = response.body();     if (responseBody != null) {      is = responseBody.byteStream();      final File file = new File(DOWN_DIR, fileName);      fos = new FileOutputStream(file);      while ((len = is.read(buf)) != -1) {       fos.write(buf, 0, len);      }      fos.flush();      //未加载内核调用方法      QbSdk.openFileReader(mContext, file.getAbsolutePath(), null, new ValueCallback<String>() {       @Override       public void onReceiveValue(String s) {        Log.e("xxx",s);       }      });      ToastUtils.showLongToast(MeetingDetailActivity.this, "下载成功,保存在Download文件夹下");     }    } catch (Exception e) {     commonProgressDialog.dismiss();     ProgressManager.getInstance().notifyOnErorr(url,e);     ToastUtils.showLongToast(MeetingDetailActivity.this, "下载失败");    } finally {     try {      if (is != null)       is.close();     } catch (IOException e) {      e.printStackTrace();     }     try {      if (fos != null)       fos.close();     } catch (IOException e) {      e.printStackTrace();     }    }   }   @Override   public void onFailure(@NonNull Call<ResponseBody> call, @NonNull Throwable t) {    t.printStackTrace();    ToastUtils.showShortToast(MeetingDetailActivity.this, "下载失败");    commonProgressDialog.dismiss();   }  }); }

FileDisplayActivity代码,对于一些包名可以切换为自己的包名，还有一些第三方库像进度展示，也可以切换为自己的进度控件
