Android + PhoneGap拦截URL(相当于iOS shouldStartLoadWithRequest)

Question

我的PhoneGap包装,本地托管的Sencha Touch应用程序使一些虚假的URL回调与本机包装器进行通信.(即app_callback://do_function_a).

在iOS中,我实现以下内容

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType;

检查app_callback://URL,调用本机函数并返回NO(以停止实际发生导航).

我可以在Android中实现等效吗？

提前致谢!

Answer 1

@Override
public void onCreate(Bundle savedInstanceState) {
    super.setBooleanProperty("showTitle", true);
    super.onCreate(savedInstanceState);

    //creates super.appView and calls setContentView(root) in DroidGap.java
    init();

    this.appView.clearCache(true);
    this.appView.clearHistory();  
    this.appView.setWebViewClient(new CordovaWebViewClient(this, this.appView) {

        @Override
        public WebResourceResponse shouldInterceptRequest(WebView view, String url) {

            Log.d("DEBUG", "Should intercept request" +url);
            //Implement your code
            return super.shouldInterceptRequest(view, url);
        }

        @Override
        public void onLoadResource(WebView view, String url) {
            Log.d("DEBUG", "onLoadResource" +url);
            //Implement your code
            super.onLoadResource(view, url);
        }



        @Override
        public void onPageFinished(WebView view, String url) {
            Log.d("DEBUG", "On page finished "+url);
            //Implement your code
            super.onPageFinished(view, url);
        }


        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {

            Log.d("DEBUG", "should override url loading "+url);
            //Implement your code
            return super.shouldOverrideUrlLoading(view, url);


        }

    });super.loadUrl("file:///android_asset/www/index.html");}

这适用于API版本9-17重要的是还添加onLoadResource

public class MainActivity extends DroidGap {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        super.setIntegerProperty("loadUrlTimeoutValue", 60000);

        this.init();

        this.appView.clearCache(true);
        this.appView.clearHistory();  

        this.appView.setWebViewClient(new CordovaWebViewClient(this, this.appView) {

            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {

                if(url.contains("app://")) {
                     url = url.replace("app://", "");
                     Log.d("DEBUG", url);

                     // DO STUFF

                     return true;
                } else {
                 //view.loadUrl(url);
                 return super.shouldOverrideUrlLoading(view, url);
                }

            }

        });

        super.loadUrl("file:///android_asset/www/index.html");
    }

}

是的，shouldOverrideUrlLoading的WebViewClient。
