Android内部没有控件来直接显示文档，跳转WPS或其他第三方文档App体验性不好，使用腾讯X5内核能很好的解决的这一问题。
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

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

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
