Question

我似乎是这样，当我在Android webview上使用我的链接位置时，它只允许我点击一次。然后，当我再次点击它时，它不会引导我到已经链接的地方。但是，当我使用2个按钮，然后交替点击它们时，它会以这种方式工作，但我需要知道如何只使用1个按钮并链接它，并能够继续使用它。下面是我对html以及webview的编码。

    public class more extends Activity{
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            getAssets();
            WebView web = new WebView(this);
            web.getSettings().setJavaScriptEnabled(true);
            web.loadUrl("file:///android_asset/more123.html");
            setContentView(web);


    }

        @Override
        public boolean onKeyDown(int keyCode, KeyEvent event) {
            if ((keyCode == KeyEvent.KEYCODE_BACK)) {
                Log.d(this.getClass().getName(), "back button pressed");
                finish();
            }
            return super.onKeyDown(keyCode, event);
        }


    }

Answer 1

boolean isClicked=false;
webView.setWebViewClient(new WebViewClient() {

            @Override
            public void onPageStarted(WebView view, String url, Bitmap favicon) {
                // TODO Auto-generated method stub

    if(url.equals("ur desired url") && isClicked==false)
    {
    //HYPER LINK IS CLICKED FIRST TIME
    isClicked=true;
                    super.onPageStarted(view, url, favicon);

    }
    else
    {
    //DO NOTHING HYPER LINK IS ALREADY CLICKED

    }



            }
        });

将此添加到您的代码可能会有所帮助;

private class myWebViewClient extends WebViewClient {
    public boolean shouldOverrideUrlLoading(WebView view, String url) 
    {
        view.loadUrl(url);
        return true;
    }
}

使用html链接位置的Webview只能点击一次超链接
