Android集成騰訊X5實(shí)現(xiàn)文檔瀏覽功能

來源：本站原創(chuàng)|時間：2020-01-10|欄目：Android|點(diǎn)擊：次

Android內(nèi)部沒有控件來直接顯示文檔，跳轉(zhuǎn)WPS或其他第三方文檔App體驗(yàn)性不好，使用騰訊X5內(nèi)核能很好的解決的這一問題。

一、下載騰訊X5內(nèi)核

1.前往https://x5.tencent.com/下載Android的內(nèi)核，新版本的騰訊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a(bǔ)pi換成implementation

2.AndroidStudio導(dǎo)入騰訊X5

a.把下載好的jar包導(dǎo)入libs，然后run as，再把jnilibs導(dǎo)入main包下

b. module的build.gradle添加cpu適配

3.Application中騰訊X5初始化,在onCreate()方法調(diào)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); 
   //此處將內(nèi)核加載是否成功的狀態(tài)保存到本地，SharePreference工具類可換為自己的
    SharedPreferenceUtils.saveBoolean(getApplicationContext(),"hasLoad",b);
   }
  });

4.應(yīng)用內(nèi)調(diào)用，無論是否加載內(nèi)核，都是把在線的文檔下載到本地然后打開，不同的是，未加載內(nèi)核會借助QQ瀏覽器或其他App的文件瀏覽功能類似微信（這個調(diào)用，騰訊X5已自動處理，我們無需關(guān)心），而加載內(nèi)核后，使用X5的TbsReaderView來打開文件，接下來就是具體代碼。

a.bulid.gradle中集成Retrofit，RxJava和進(jìn)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'

寫網(wǎng)絡(luò)下載工具

public interface LoadFileApi {
 @GET
 Call<ResponseBody> loadPdfFile(@Url String fileUrl);
}
public class LoadFileModel {
 //使用該方法來下載文件
 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.具體調(diào)用

首先注冊文件進(jìn)度下載監(jiān)聽

private ProgressDialog commonProgressDialog;//切換為自己的進(jìn)度控件
 private ProgressInfo mLastDownloadingInfo;
 ProgressManager.getInstance().addResponseListener(url, new ProgressListener() {
            @Override
            public void onProgress(ProgressInfo progressInfo) {
             if (mLastDownloadingInfo == null) {
              mLastDownloadingInfo = progressInfo;
             }
             //因?yàn)槭且哉埱箝_始時的時間作為 Id ,所以值越大,說明該請求越新
             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()) {
              //說明已經(jīng)下載完成
              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();
              }
             });
            }
           });
          }

然后打開文件

private static final String DOWN_DIR = Environment.getExternalStorageDirectory()
   + File.separator+"Download"; //文件下載的路徑，可以自定義
//打開文件
 private void openFile(String filePath,String fileName) {
  boolean hasLoad = SharedPreferenceUtils.getBoolean(mContext, "hasLoad");//是否記載內(nèi)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,"當(dāng)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, "已下載過了");
   }
  }
 }
 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();
      //未加載內(nèi)核調(diào)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, "下載成功,保存在Download文件夾下");
     }
    } catch (Exception e) {
     commonProgressDialog.dismiss();
     ProgressManager.getInstance().notifyOnErorr(url,e);
     ToastUtils.showLongToast(MeetingDetailActivity.this, "下載失敗");
    } 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, "下載失敗");
    commonProgressDialog.dismiss();
   }
  });
 }
