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();
   }
  });
 }
