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
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
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
