when I run this code, "google.com" open in web application (for examaple google chrome) and not in the webView in the dialog.
It's does work OK with some urls.
Why?
final Dialog dialog=new Dialog(this.activity,android.R.style.Theme_Black_NoTitleBar_Fullscreen);
dialog.setContentView(R.layout.full_page_ad_between_chapters);
WebView webView = (WebView) dialog.findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://google.com");
R.layout.full_page_ad_between_chapters :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="350dp"
android:layout_height="1000dp"
android:layout_margin="5dp"
android:orientation="vertical" >
<Button
android:id="#+id/fullPageAdBetweenChaptersClose"
android:layout_width="100dp"
android:layout_height="40dp"
android:layout_gravity="center"
android:text="סגור" />
<WebView
android:id="#+id/webView1"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
You need to override the method shouldOverrideUrlLoading() on your WebViewClient.
WebView webView = (WebView) dialog.findViewById(R.id.webView1);
webView.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// check if we want to open the url into the WebView
if (iWantToOpenTheUrlIntoTheWebView(url)) {
return false;
}
// let the system handle the url outside of the app
return true;
}
});

I have an html file in my website:
http://manizani.ir/hamyar_gas_php/map/map_app.html
I want to show it on my Android Application. I created an Activity and use a Webview to load above url. But nothing is loaded and it shows me just an empty activity.
I can load any other web pages successfully, but not about my url.
Please help me to solve it.
Thanks a lot

I'd like to load a website in webview with UTF-8, because I'm having accentuation problems, so I'm trying:
myWebView.loadDataWithBaseURL("http://www.planalto.gov.br/ccivil_03/constituicao/constituicaocompilado.htm", "", "text/html", "UTF-8", null);
but the result is a blank screen.
If I use loadURL("site") it loads, but I have accentuation problems. any ideas?
edit --
my webview setup:
WebView myWebView = findViewById(R.id.webView1);
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setAppCacheEnabled(true);
webSettings.setDefaultTextEncodingName("utf-8");
myWebView.setWebViewClient(new MyWebViewClient());
public class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}

You will need to use loadUrl to load the link.
loadDataWithBaseUrl is not meant to load the given baseUrl into the WebView. It is meant to load the data that you pass as data into the WebView (documentation). Say you want to have "Hello World!" written in your WebView:
webview.loadDataWithBaseURL(url, "<html><body>Hello World.</body></html>", null, "UTF-8", null)
Regarding the encoding: when using loadUrl you should not need to set UTF-8 explicitly because it is the default. Using ISO-8859-1 worked for the specific page you want to load:
webSettings.defaultTextEncodingName = "ISO-8859-1"
there are two webviews in scrollview.
<ScrollView>
<LinearLayout>
<WebView></WebView>
<WebView></WebView>
</LinearLayout>
</ScrollView>
I want to make two webviews looks like one webpage. currently, my solution is make webview's height equal to webview's contentHeight. and disable scrollability of webview. but for very big html. it's not a good solution. webview has to render the whole html. I want to use nestedscrollview. make two webviews' height equals to nestedscrollview's height. but I dont known how to deal the events.
Try this to make two WebView looks like one webpage.
public class MainActivity extends Activity {
String url = "http://www.yahoo.com";
String url1 = "http://www.google.com";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.d("MainActivity", "Activity one");
WebView webview = (WebView) findViewById(R.id.webView1);
webview.getSettings().setJavaScriptEnabled(true);
webview.setWebViewClient(new WebViewController());
webview.loadUrl(url);
WebView webview2 = (WebView) findViewById(R.id.webView2);
webview2.getSettings().setJavaScriptEnabled(true);
webview2.setWebViewClient(new WebViewController());
webview2.loadUrl(url1);
}
}

I am trying to stream a video stored on dropbox on android's webview but only a blank space is
displayed, my code is below :
activity_web_view.xml
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<WebView
android:id="#+id/webView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView
android:id="#+id/tview1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/webView"
android:text="Description" >
</TextView>
</RelativeLayout>
public class WebViewA extends Activity {
private WebView webView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_web_view);
webView = (WebView) findViewById(R.id.webView);
webView.setWebViewClient(new WebViewClient());
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("https://www.dropbox.com/s/XXXX/video.mp4?dl=0?client_id=XXXX");
}
}
I have also tried the following Urls on webView.loadUrl(), but none
of them work, only a blank space appears :
"https://dl.dropbox.com/s/XXXX/video1.mp4?dl=0?client_id=XXXX"
"https://dl.dropbox.com/s/XXXX/video2.mp4?dl=1?client_id=XXXX"
"https://dl.dropboxusercontent.com/s/XXXX/video1.mp4"
"https://www.dropbox.com/s/XXXX/video1.mp4?dl=0"
if I try http://www.google.com it works, I have also seen some tutorials
with dropbox addresses that have an 'u' instead of an 's' like
"https://www.dropbox.com/u/..."
does WebView only works with dropbox urls with an 'u', if so how can I
get that type of address.
If i start this application, i can see the webview correctly, but it doesn't load google maps (https://maps.google.com/maps?q=43.0054446,-87.9678884&t=m&z=7), but it loads the normal google page (https://www.google.it/#q=43.0054446%2C-87.9678884). Why? Is there a way to fix it?
public class MainActivity extends Activity
{
WebView myWebView;
String mapPath = "https://maps.google.com/maps";
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myWebView = (WebView)findViewById(R.id.mapview);
String map2="?q=43.0054446,-87.9678884&t=m&z=7";
myWebView.loadUrl(mapPath+map2);
}
#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;
}
}
Now i have another problem. This is my xml Layout.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="#+id/textview"
android:layout_height="#string/hello_world"/>
</RelativeLayout>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<WebView
android:id="#+id/mapview"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
I want to display the WebView in the upper half of the screen, but when the link is loaded, the page is fullscreen (even if i insert something else under the webview). Why?
I just removed the S from the httpS and it works. I don't know if this can help.
For me I was missing the myWebView.getSettings().setJavaScriptEnabled(true);.
This is my code:
//set the webview and have open the map
mywebview = (WebView) findViewById(R.id.webView);
WebSettings webSettings = mywebview.getSettings();
webSettings.setBuiltInZoomControls(true);
mywebview.getSettings().setJavaScriptEnabled(true);
mywebview.setWebViewClient(new Callback());
mywebview.loadUrl(mapPath+map2);
Thanks to the commenter adding that, I was going a little nuts.
