Android 用腾讯X5内核加载 word ppt  先下载在加载。

 

第一步 下载Sdk 导入项目  

 

 第二步 下载 pdf word到本地

 

1. 调用下载  DownloaderTask task = new DownloaderTask();   task.execute();

  /**
     * 任务类
     */
    private class DownloaderTask extends AsyncTask<String, Void, String> {
 
        @Override
        protected String doInBackground(String... params) {
 
            String url = "下载地址";
            String fileName = url.substring(url.lastIndexOf("/") + 1);
            try {
                fileName = URLDecoder.decode(fileName, "UTF-8");
            } catch (UnsupportedEncodingException e) {
                e.printStackTrace();
            }
//            MyLogger.i("download", "fileName=" + fileName);
            try {
                URL resUrl = new URL(url);
                HttpURLConnection conn = (HttpURLConnection) resUrl.openConnection();
                conn.connect();
                InputStream input = conn.getInputStream();
                DownloadUtils.writeToSDCard(fileName, input);
                input.close();
                return fileName;
            } catch (Exception e) {
                e.printStackTrace();
                return null;
            }
        }
 
        @Override
        protected void onCancelled() {
            super.onCancelled();
        }
 
        @Override
        protected void onPostExecute(String result) {
            super.onPostExecute(result);
            DownloadUtils.closeProgressDialog();
            if (result == null) {
//                ToastUtils.showShortToast(ClassroomlearningActivity.this, R.string.msg_downloaderror);
                return;
            }
            //            ToastUtils.showShortToast(ClassroomlearningActivity.this, R.string.msg_downloadsuccess);
            String dir = DownloadUtils.getDownloadPath() + result;
 
           //下载完 跳转到  WabActivitry 页面 使用 TbsReaderView  加载 H5
 
            startActivity(new Intent(getBaseContext(), WabActivitry.class).putExtra("path", dir));
 
 
//            Wps.createInstance(ClassroomlearningActivity.this).open(new File(dir));
 
        }
 
        @Override
        protected void onPreExecute() {
            super.onPreExecute();
            DownloadUtils.showProgressDialog(ClassroomlearningActivity.this);
        }
 
        @Override
        protected void onProgressUpdate(Void... values) {
            super.onProgressUpdate(values);
        }
 
    }

 第三步 根据路径加载 Wabview

layout  和  xml代码
 
 
<RelativeLayout
 
        android:id="@+id/X5TbsView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/colorPrimary"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />
 
 
调用代码
 
public void displayFile(String fileModel) {
        mTbsReaderView = new TbsReaderView(this, this);
        //增加下面一句解决没有TbsReaderTemp文件夹存在导致加载文件失败
        String bsReaderTemp = tbsReaderTemp;
 
//        Log.i("eeee","tbsReaderTemp"+bsReaderTemp);
        File bsReaderTempFile = new File(bsReaderTemp);
 
        if (!bsReaderTempFile.exists()) {
            Log.d("print", "文件不存在准备创建/TbsReaderTemp！！");
            boolean mkdir = bsReaderTempFile.mkdir();
            if (!mkdir) {
                Log.d("print", "创建/TbsReaderTemp失败！！！！！");
            }
            Toast.makeText(this, "文件不存在！", Toast.LENGTH_SHORT).show();
        }
        mRelativeLayout.addView(mTbsReaderView, new RelativeLayout.LayoutParams(-1, -1));
        Bundle bundle = new Bundle();
        bundle.putString("filePath", fileModel);
        bundle.putString("tempPath", "" + getIntent().getStringExtra("name"));
        boolean result = mTbsReaderView.preOpen(getFileType("" + fileModel), false);
        Log.d("print", "查看文档---" + result);
        if (result) {
 
 
            mTbsReaderView.openFile(bundle);
        } else {
 
        }
    }
 
 
    private String getFileType(String paramString) {
        String str = "";
 
        if (TextUtils.isEmpty(paramString)) {
            Log.d("print", "paramString---->null");
            return str;
        }
        Log.d("print", "paramString:" + paramString);
        int i = paramString.lastIndexOf('.');
        if (i <= -1) {
            Log.d("print", "i <= -1");
            return str;
        }
 
        str = paramString.substring(i + 1);
        Log.d("print", "paramString.substring(i + 1)------>" + str);
        return str;
    }
 
  //消失记得销毁
   @Override
    protected void onDestroy() {
        super.onDestroy();
        if (mTbsReaderView != null) {
            mTbsReaderView.onStop();
            mTbsReaderView.destroyDrawingCache();
        }
    }

 

3. 切记初始化 X5内核 

 

public class Myapp extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
 
 
        ;
        //x5内核初始化接口
        QbSdk.initX5Environment(getApplicationContext(), cb);
 
    }
 
    /**
     * 搜集本地tbs内核信息并上报服务器，服务器返回结果决定使用哪个内核。
     */
    QbSdk.PreInitCallback cb = new QbSdk.PreInitCallback() {
 
        @Override
        public void onViewInitFinished(boolean arg0) {
            //x5內核初始化完成的回调，为true表示x5内核加载成功，否则表示x5内核加载失败，会自动切换到系统内核。
            Log.e("APPAplication", " onViewInitFinished is " + arg0);
        }
 
        @Override
        public void onCoreInitFinished() {
            Log.e("APPAplication", " onCoreInitFinished");
        }
    };
 
}
