重构WebView 数据封装 和 传输对象

前言：最近重构毕业设计，经过实习后，觉得以前写的真的不算好，很多东西还可以优化，重构，代码复用。现在写的也不算漂亮，但是对自己整个大学生涯要有个总结。

添加加载进度条，WebView封装成工具类，传输数据对象

public class WebViewUtil {
    @SuppressLint("JavascriptInterface")
    public void ClientWebView(final Activity mactive, WebView webView, final ProgressBar progressBar, String url){

        WebSettings webSettings = webView.getSettings();
        //支持js
        webSettings.setJavaScriptEnabled(true);
        // 是否可访问本地文件，默认值 true
        webSettings.setAllowFileAccess(true);
        //自适应屏幕
        webSettings.setLoadWithOverviewMode(true);
        //动态更新内容
        webSettings.setCacheMode(WebSettings.LOAD_DEFAULT);
        //支持自动加载图片
        webSettings.setLoadsImagesAutomatically(true);
        // 是否支持缩放
        webSettings.setSupportZoom(false);
        // 设置出现缩放工具
        webSettings.setBuiltInZoomControls(true);
        //扩大比例的缩放
        webSettings.setUseWideViewPort(true);

        webSettings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.SINGLE_COLUMN);
        webSettings.setPluginState(WebSettings.PluginState.ON);
        // 是否可用Javascript(window.open)打开窗口，默认值 false
        webSettings.setJavaScriptCanOpenWindowsAutomatically(true);
        // 设置可现实js的alert弹窗
        webView.setWebChromeClient(new WebChromeClient());

        webView.setWebChromeClient(new WebChromeClient(){
            @Override
            public void onProgressChanged(WebView view, int newProgress) {
                progressBar.setProgress(newProgress);
                if (newProgress == 100) {
                    progressBar.setVisibility(View.GONE);
                }
            }});

        webView.setWebViewClient(new WebViewClient() {
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                view.loadUrl(url);
                return true;
            }

            @Override
            public WebResourceResponse shouldInterceptRequest(WebView webView, WebResourceRequest webResourceRequest) {
                WebResourceResponse response = null;
                response =  super.shouldInterceptRequest(webView, webResourceRequest);
                return response;

            }

            @Override
            public WebResourceResponse shouldInterceptRequest(WebView webView, String s) {
                WebResourceResponse response = null;
                response =  super.shouldInterceptRequest(webView, s);
                String[] namelist = s.split("/");
                return response;
            }
        });
        webView.loadUrl(url);
    }
}

传递一个对象，该对象使用serializable序列化

public class WebUrl implements Serializable {
    String title;
    String url;

    public WebUrl(String title, String url) {
        this.title = title;
        this.url = url;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getUrl() {
        return url;
    }

    public void setUrl(String url) {
        this.url = url;
    }
}

跳转到WebViewActivity,携带对象

 skipWebView("两学一做", "http://www.bhu.edu.cn/newsgl/page/lxyz/");

    private void skipWebView(String title, String url) {
        WebUrl webUrl = new WebUrl(title, url);
        Bundle bundle = new Bundle();
        bundle.putSerializable("WebUrl", webUrl);
        startActivity(WebViewActivity.class, bundle);
    }

WebViewActivity.class

public class WebViewActivity extends BaseActivity {

    @BindView(R.id.progressBar)
    ProgressBar progressBar;
    @BindView(R.id.webView)
    WebView webView;

    @Override
    protected int contentViewID() {
        return R.layout.activity_webview;
    }

    @Override
    protected void initialize() {
        Intent intent = getIntent();
        WebUrl webUrl = (WebUrl) intent.getSerializableExtra("WebUrl");
        setTopTitle(webUrl.getTitle(), true);
        setLeftBtnFinish();
        WebViewUtil webViewUtil = new WebViewUtil();
        webViewUtil.ClientWebView(this,webView,progressBar,webUrl.getUrl());
    }

    @OnClick({R.id.arrow_left, R.id.arrow_right})
    public void onClick(View view) {
        switch (view.getId()){
            case R.id.arrow_left:
                if (webView.canGoBack()) {
                    webView.goBack();
                } else {
                    Toast.makeText(this, getString(R.string.tip_web_left),  Toast.LENGTH_LONG).show();
                    return;
                }
                break;
            case R.id.arrow_right:
                if (webView.canGoForward()) {
                    webView.goForward();
                } else {
                    Toast.makeText(this, getString(R.string.tip_web_right), Toast.LENGTH_LONG).show();
                    return;
                }
                break;
            default:
        }

    }
}
