flutter 打开办公文件 pdf ppt xlsx 等等（仅Android）

项目clone地址：
https://github.com/mrliuwen/lw_x5_webview_flutter.git

起因：肺炎闹产品要

实现方式：之前在pub库里看到一个X5的恨遗憾的实现方式是用的直接open。不是用TbsReaderView
后面我替换用TbsReaderView重写了打开文件这部分需要自定义的懂android原生的小伙伴可以直接在原生部分修改FileActivity这个类

使用方式：见代码

注意使用过程中关于xml的配置详情可以借鉴 demo中android xml的配置主要是privoder 和filepath

建议用demo地址学习

import ‘package:flutter/cupertino.dart’;
import ‘package:flutter/material.dart’;
import ‘package:x5_webview/x5_sdk.dart’;

import ‘package:dio/dio.dart’;

void main() {
X5Sdk.setDownloadWithoutWifi(true); //没有x5内核，是否在非wifi模式下载内核。默认false
X5Sdk.init().then((isOK) {
print(isOK ? “X5内核成功加载” : “X5内核加载失败”);
});
runApp(MyApp());
}

class MyApp extends StatefulWidget {
@override
_MyAppState createState() => _MyAppState();
}

class _MyAppState extends State {
@override
void initState() {
super.initState();
}

@override
Widget build(BuildContext context) {
return MaterialApp(home: HomePage());
}
}

class HomePage extends StatefulWidget {
@override
_HomePageState createState() => _HomePageState();
}

class _HomePageState extends State {
String localPath = ‘/storage/emulated/0/Android/data/io.morbit.morbit_flutter/files/logs.csv’; //android x5文件sdk需要正确格式本地文件才能正确打开
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text(‘X5打开本地文件示例’),
),
body: Center(
child: InkWell(
child: Text(‘打开’),
onTap: () {
X5Sdk.openFile(localPath);
},
),
),
);
}
}

原生fileActivity代码如下

package com.cjx.x5_webview;

import android.app.ActionBar;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.os.Environment;
import android.util.Log;
import android.view.ViewGroup;
import android.widget.RelativeLayout;

import com.tencent.smtt.sdk.TbsReaderView;

import java.io.File;
import java.util.List;

public class FileActivity extends Activity {

private TbsReaderView mTbsReaderView;

private String filePath = "";
private String title = "";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_displayfile);
    initTbsReaderView();
    Intent intent = getIntent();
    filePath = intent.getStringExtra("filepath");
    ActionBar actionBar = getActionBar();
    try {
        title = filePath.substring(filePath.lastIndexOf("/") + 1);
    } catch (Exception e) {
    }
    actionBar.setTitle(title);
    displayFile(filePath);
}

@Override
protected void onDestroy() {
    super.onDestroy();
    mTbsReaderView.onStop();
}

RelativeLayout rootRl;

private void initTbsReaderView() {
    mTbsReaderView = new TbsReaderView(FileActivity.this, new TbsReaderView.ReaderCallback() {
        @Override
        public void onCallBackAction(Integer integer, Object o, Object o1) {
        }
    });
    rootRl = (RelativeLayout) findViewById(R.id.root_layout);
    rootRl.addView(mTbsReaderView, new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
}

private void displayFile(String filePath) {
    boolean isCan = false;
    isCan = this.mTbsReaderView.preOpen(parseFormat(filePath), false);
    Log.d("FileActivity2222", isCan + "");
    if (isCan) {
        String bsReaderTemp = "/storage/emulated/0/TbsReaderTemp";
        File bsReaderTempFile = new File(bsReaderTemp);

        if (!bsReaderTempFile.exists()) {
            boolean mkdir = bsReaderTempFile.mkdir();
            if (!mkdir) {
                Log.e("TAG", "创建/storage/emulated/0/TbsReaderTemp失败！！！！！");
            }
        }
        Bundle bundle = new Bundle();
        bundle.putString("filePath", filePath);
        bundle.putString("tempPath", Environment.getExternalStorageDirectory().toString() + "/" + "TbsReaderTemp");
        mTbsReaderView.openFile(bundle);
    }

}

private String parseFormat(String fileName) {
    return fileName.substring(fileName.lastIndexOf(".") + 1);
}

}
