WebView wird nicht geladen, nachdem Internetberechtigungen erteilt wurden?

Question

Ich versuche, ein WebView zu verwenden, um eine Webseite in meiner Anwendung anzuzeigen. Zuerst hatte ich keine Berechtigungen in der AndroidManifest.xml und ich bekam den Fehler 'die Webseite konnte nicht geladen werden, da net :: ERR_CACHE_MISS'

Aber jetzt, dass ich die Berechtigung zum AndroidManifest hinzugefügt haben. XML wird das WebView als leeres weißes Feld geladen.

Hier ist meine AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
package= ... > 

<uses-permission android:name="android.permission.INTERNET" /> 

<application ... 
</application> 

</manifest> 

Und meine Java-Klasse:

public class location_Fragment extends Fragment { 

private WebView webView; 

View rootview; 

@Nullable 
@Override 

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

    rootview = inflater.inflate(R.layout.location_layout, container, false); 
    webView = (WebView)rootview.findViewById(R.id.webView); 

    WebSettings webSettings = webView.getSettings(); 
    webSettings.setJavaScriptEnabled(true); 

    webView.loadUrl("https://www.google.com"); 
    return rootview; 
    } 
} 

Answer 1

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

     rootview = inflater.inflate(R.layout.location_layout, container, false); 
     webView = (WebView)rootview.findViewById(R.id.webView); 
     webView.setWebViewClient(new MyBrowser()); 
     WebSettings webSettings = webView.getSettings(); 
     webSettings.setJavaScriptEnabled(true); 

     webView.loadUrl("https://www.google.com"); 
     return rootview; 
     } 
    } 

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

Mit folgendem Code

public class WebViewActivity extends AppCompatActivity { 
    private WebView webView; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_web_view); 
     Bundle b = getIntent().getExtras(); 
     String data =b.getString("link"); 
     webView = (WebView) findViewById(R.id.webView1); 

     webView.setWebViewClient(new MyWebViewClient()); 
     webView.getSettings().setJavaScriptEnabled(true); 
     webView.getSettings().setBuiltInZoomControls(true); 
     if(data.equals("")||data.equals("null")) { 
      Toast.makeText(WebViewActivity.this,"No Link Available",Toast.LENGTH_SHORT).show(); 
     } 
     { 
      webView.loadUrl(data); 
     } 
     webView.setWebChromeClient(new WebChromeClient() { 
      public void onProgressChanged(WebView view, int progress) { 
       // Activities and WebViews measure progress with different scales. 
       // The progress meter will automatically disappear when we reach 100% 
       // activity.setProgress(progress * 1000); 
       WebViewActivity.this.setTitle("Loading..."); 
       WebViewActivity.this.setProgress(progress * 100); 
       if(progress == 100) 
        WebViewActivity.this.setTitle(R.string.app_name); 
      } 
     }); 
    } 

    private class MyWebViewClient extends WebViewClient { 
     private ProgressDialog pDialog; 
     @Override 
     public boolean shouldOverrideUrlLoading(WebView view, String url) { 
      // pDialog = new ProgressDialog(WebViewActivity.this,R.style.DialogTheme); 
      view.loadUrl(url); 
      return true; 
     } 
     //Show loader on url load 
     public void onLoadResource (WebView view, String url) { 
      if (pDialog == null) { 
       // in standard case YourActivity.this 
       pDialog = new ProgressDialog(WebViewActivity.this,R.style.DialogTheme); 
       pDialog.setMessage("Loading..."); 
       pDialog.show(); 
      } 
     } 

     @Override 
     public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) { 
      handler.proceed(); 
     } 

     public void onPageFinished(WebView view, String url) { 
      try{ 
       pDialog.dismiss(); 
       if (pDialog.isShowing()) { 
        pDialog.dismiss(); 
        pDialog = null; 
       } 
      }catch(Exception exception){ 
       exception.printStackTrace(); 
      } 
     } 
    } 
    @Override 
    public boolean onKeyDown(int keyCode, KeyEvent event) { 
     if (event.getAction() == KeyEvent.ACTION_DOWN) { 
      switch (keyCode) { 
       case KeyEvent.KEYCODE_BACK: 
        if (webView.canGoBack()) { 
         webView.goBack(); 
        } else { 
         finish(); 
        } 
        return true; 
      } 

     } 
     return super.onKeyDown(keyCode, event); 
    } 

}
