Android集成腾讯X5内核浏览功能

集成SDK参考：https://x5.tencent.com/docs/access.html

需求：实现本地文件的浏览，包括不限于PDF,WORD,EXECEL等等

1、引入依赖

implementation 'com.tencent.tbs:tbssdk:44165'

2、创建三个类

代码语言：javascript复制

public class X5App {
    public void initX5app(Context context){
        //设置非wifi条件下允许下载X5内核
        QbSdk.setDownloadWithoutWifi(true);

        //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，true表x5内核加载成功，否则表加载失败，会自动切换到系统内核。
                Log.d("app", " 内核加载 "   arg0);
            }
            @Override
            public void onCoreInitFinished() {
            }
        };

        //x5内核初始化接口
        QbSdk.initX5Environment(context,  cb);
    }
}

代码语言：javascript复制

public class X5WebView extends WebView {
    private WebViewClient client = new WebViewClient() {
        /**
         * 防止加载网页时调起系统浏览器
         */
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }
    };
    @SuppressLint("SetJavaScriptEnabled")
    public X5WebView(Context arg0, AttributeSet arg1) {
        super(arg0, arg1);
        this.setWebViewClient(client);
        initWebViewSettings();
        this.getView().setClickable(true);
    }
    private void initWebViewSettings() {
        WebSettings mWebSettings = this.getSettings();
        mWebSettings.setJavaScriptEnabled(true);
        mWebSettings.setJavaScriptCanOpenWindowsAutomatically(true);
        mWebSettings.setAllowFileAccess(true);
        mWebSettings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.NARROW_COLUMNS);
        mWebSettings.setSupportZoom(true);
        mWebSettings.setBuiltInZoomControls(true);
        mWebSettings.setUseWideViewPort(true);

        mWebSettings.setAppCacheEnabled(true);
        mWebSettings.setDomStorageEnabled(true);
        mWebSettings.setGeolocationEnabled(true);
        mWebSettings.setAppCacheMaxSize(Long.MAX_VALUE);
        mWebSettings.setPluginState(WebSettings.PluginState.ON_DEMAND);
        mWebSettings.setCacheMode(WebSettings.LOAD_NO_CACHE);
    }
    public X5WebView(Context arg0) {
        super(arg0);
        setBackgroundColor(85621);
    }
}

public class X5TbsFileServicePage extends AppCompatActivity implements TbsReaderView.ReaderCallback {

    private String tbsReaderTemp = Environment.getExternalStorageDirectory()   "/TbsReaderTemp";
    TbsReaderView mTbsReaderView;
    RelativeLayout mRelativeLayout;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_x5_tbs_file_service_page);
        // 绑定容器
        mRelativeLayout = findViewById(R.id.X5TbsView);
//        FileModel fileModel = new FileModel();
//        fileModel.setPath("/storage/emulated/0/demo/word.docx");
//        displayFile(fileModel);
    }

    public void displayFile(FileModel 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;
        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.getPath());
        bundle.putString("tempPath", tbsReaderTemp);
        boolean result = mTbsReaderView.preOpen(getFileType("word.docx"), 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;
    }

    @Override
    public void onCallBackAction(Integer integer, Object o, Object o1) {
        Log.i("触摸监听："," ");
    }

    /**
     * 返回上个页面
     * @param keyCode
     * @param event
     * @return
     */
    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        return super.onKeyDown(keyCode, event);
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        if (mTbsReaderView != null) {
            mTbsReaderView.onStop();
            mTbsReaderView.destroyDrawingCache();
        }
    }

}

3、在Application中的OnCreate方法中进行初始化

代码语言：javascript复制

new X5App().initX5app(mContext);

4、使用

通过点击事件触发预览 Kotlin版

代码语言：javascript复制

            //预览事件
            stvOpen.setOnClickListener(View.OnClickListener {
                val extraParams = HashMap<String, String>()
                extraParams["style"] = "1"
                extraParams["local"] = "true"
                QbSdk.openFileReader(this, fileName?.absolutePath, extraParams, object : ValueCallback<String?> {
                    override fun onReceiveValue(s: String?) {
                        Log.e("TAG", "OpenFile Callback: $s")
                        if ("openFileReader open in QB" == s || "filepath error" == s || "TbsReaderDialogClosed" == s || "fileReaderClosed" == s) {
                            QbSdk.closeFileReader(me)
                        }
                    }
                })
            })
