Question

如何在单击WebView下拉菜单中的链接时更改片段或转到另一个活动。目前我正在使用它下面的代码工作。但我需要转到另一个片段而不是Activity。

    WebView webView = (WebView) findViewById(R.id.webView1);
    webView.getSettings().setJavaScriptEnabled(true);
    String url =  "file:///android_asset/index.html";
    webView.loadUrl(url);
     if (url.equals("file:///android_asset/index5.html")) {
            Intent intent = new Intent(MainActivity.this, NextActivity.class);
            startActivity(intent);
            return;
     }

}

我试过了

WebView webView = (WebView) findViewById(R.id.webView1);
    webView.getSettings().setJavaScriptEnabled(true);
    String url = "file:///android_asset/index.html";
    webView.loadUrl(url);
    if (url.equals("file:///android_asset/index5.html")) {
  //            Fragment  fr = new FragmentOne();

   //              fm = getFragmentManager();
  //              fragmentTransaction = fm.beginTransaction();
 //              fragmentTransaction.replace(R.layout.my_account, fr);
//              fragmentTransaction.commit(); 

            Fragment newFragment = new FragmentOne();
            FragmentTransaction transaction = getFragmentManager().beginTransaction();

          // Replace whatever is in the fragment_container view with this fragment,
          // and add the transaction to the back stack
          transaction.replace(R.layout.activity_main, newFragment);
          transaction.addToBackStack(null);

          // Commit the transaction
          transaction.commit();

    }

}

FragmentOne.java

public class FragmentOne extends Fragment implements OnClickListener{


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View view = inflater.inflate(R.layout.my_account, container, false);
    return view;

}



@Override
public void onClick(View arg0) {
    // TODO Auto-generated method stub

}

}

但它没有替换片段

谢谢，

这应该适合你：

mWebView.setWebViewClient(new MyWebViewClient());

private class MyWebViewClient extends WebViewClient {

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

        if (url.equals("file:///android_asset/index5.html")) {
            //Launch new activity here
            return true;
        }
        return false;
    }
}
