问题描述
我创建了一个小程序,可以在 webview 中加载特定的网站.我想密切关注 URL,如果 URL 包含xxx"字样,那么它应该导航到另一个页面.例如,如果我设置 www.example.com.我现在可以导航到 www.example.com 的任何页面.如果我的网址包含像xxx"这样的词,那么我想退出该网址并导航到另一个网址.有可能吗?如何?谢谢.
I have created a small program that will load particular website in webview.I want to keep watch on URL and if URL contains 'xxx' word then it should navigate to another page.for example if I set www.example.com. and I can now navigate to any page of www.example.com. If my Url contains word like 'xxx' then I want to exit that url and navigate to another url.Is is possible?and how?Thanks.
//Here is my code.
public class MainActivity extends Activity {
private WebView Browser;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Browser = (WebView) findViewById(R.id.webView1);
Browser.setWebViewClient(new WebViewClient()
{
@Override
public void onLoadResource(WebView view, String url) {
// TODO Auto-generated method stub
super.onLoadResource(view, url);
}
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
System.out.println("when you click on any interlink on webview that time you got url :-" + url);
int len = url.length();
if(url.contains("xxx"))
{
url = "http://www.example.com/xxxx";
Toast.makeText(MainActivity.this, "URL changed.."+url, Toast.LENGTH_LONG).show();
}
else
Toast.makeText(MainActivity.this, "URL not changed.."+url, Toast.LENGTH_LONG).show();
return super.shouldOverrideUrlLoading(view, url);
}
});
Browser.getSettings().setLoadsImagesAutomatically(true);
Browser.getSettings().setJavaScriptEnabled(true);
Browser.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
Browser.loadUrl("http://www.example.com/");
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
推荐答案
是的.. 您可以导航 webview 运行时.将您的逻辑放入 WebViewClient 的 onPageFinished() 方法中.
yes.. you can navigate webview runtime. Put your logic into onPageFinished() method of WebViewClient.
public void onPageFinished(WebView view, String url) {
if (webView.getUrl().contains("xxx")) {
URL = "http://www.example.com/xxxx";
webView.loadUrl(URL);
}
}
