我一直在尝试使用webview过去一小时,但我无法绕过它,这真让我烦恼..

我不知道我的应用程序中是否存在错误,或者我是以错误的方式执行此操作 和 无论我尝试什么,页面都无法加载

我已经包含了INTERNET的许可

代码如下 对于启动webview的活动如下

dialog=ProgressDialog.show(this,"loading","please wait...",true);
    dialog.setCancelable(false);


    Uri url = getIntent().getData();
    webView = (WebView) findViewById(R.id.webview2);
    webView.setWebViewClient(new client(this));
    webView.getSettings().setJavaScriptEnabled(true);
    webView.getSettings().setLoadWithOverviewMode(true);
    webView.getSettings().setUseWideViewPort(true);
    webView.loadUrl(url.toString());

和webviewclient代码如下

class client extends WebViewClient {
    Context c;

    client(Context c) {
        this.c=c;


    }

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        Log.d("viru","overide");
        dialog.show();
        view.loadUrl("http://www.google.com");

        return true;
    }

    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) {
        Log.d("viru","started");
        Toast.makeText(c, "page started", Toast.LENGTH_LONG).show();
    }

    @Override
    public void onPageFinished(WebView view, String url) {
        Log.d("viru","finished");

        Toast.makeText(c, "page finished", Toast.LENGTH_LONG).show();

        dialog.dismiss();
    }
}

logcat持续吐痰如下

01-24 14:58:25.858 28975-28975/com.example.viru.webview D/viru: started
01-24 14:58:26.263 28975-28975/com.example.viru.webview D/viru: started
01-24 14:58:26.409 28975-28975/com.example.viru.webview D/viru: overide

01-24 14:58:26.441 28975-28975/com.example.viru.webview D/viru: started
01-24 14:58:28.913 28975-28975/com.example.viru.webview D/viru: finished
01-24 14:59:15.226 28975-28975/com.example.viru.webview D/viru: overide
01-24 14:59:15.291 28975-28975/com.example.viru.webview D/viru: started
01-24 14:59:17.007 28975-28975/com.example.viru.webview D/viru: finished

请解释webview架构如何工作以及如何通过这个无限循环.. 它真的很烦我..... 提前谢谢......
