After a successful web view is loaded, now after some processing on the HTML page, I would like to return the control to the main screen. Is this possible in Android?
The control after the webview is launched, is in the browser, so after I make some ajax calls and then get a positive server side message. I would like the control goback to my Webview Activity.

I call WebView.clearHistory(), but I am still able to go back after doing so. I want to reuse a WebView, but I don't want the back button to allow the user to go back further than the current "session" of using the WebView. Anybody know what is the best way to handle this? I thought for sure that clearHistory() would do it.
View 3 Replies View RelatedI've implemented a list with each item as a WebView. The WebViews are loaded in their own threads so the UI doesn't have to wait.
The problem I've ran into is after the list is loaded, some webview items disappears or repeat after the list is scrolled. I've read posts from Romain Guy and others about how this is a bad idea. Just wondering if it's still a bad idea or a solution has been found since Cupcake.
In my android app I have a Tabhost with a ListView as one of the tabs. By clicking on an item in the ListView (an address) I start an Intent to Google Maps for directions and the choice dialog pops up for google maps, web browser etc. Problem is if I press the hard back button then the launch dialog goes away but also the ListView is cleared. Any idea why?
View 1 Replies View RelatedI think this has been asked elsewhere (StackOverflow) but with no satisfactory answer.
I have a ListView where each row is composed (mostly) of a WebView.
The "problem" is that you can't touch the WebView and fire the onListItemClick method of ListActivity.
I've tried to set android:clickable="false" in the xml file, but this also doesn't allow me to "click" on the WebView.
From another thread (http://groups.google.com/group/android-developers/ browse_thread/thread/684162fdf5a073ec), I've seen others state that putting a WebView in a ListView is "bad form" (e.g., "I don't see a situation where a WebView cannot be replaced by a text view or a combination of other compoenents [sic]. I still think this is a bad idea."),
Given this opinion, I think I should explain my "situation".
Each row in the ListView will contain a question whose contents vary.
The contents of the row will require formatted text (bold, italics, superscript, subscript, etc.) and 1 or more images. To me, this seems like an ideal situation for a WebView, because I don't know ahead of time what the specific order and structure of the text images will be.
So....I guess I have a few questions.
Is it possible to allow users to "click" on a WebView placed in a ListView and fire onListItemClick? If so, how? Given my needs, is there another way to structure my ListView rows without using a WebView? If so, what is it?
As you can see, I first create a webview. Then, I want it to immediately disappear. Then, I want the Listview to come up. But the problem is, I can't do Listview if I don't do ListActivity but then I can't do Activity. Code...
View 2 Replies View RelatedIs there a way to show that a WebView item contained as a item in a ListView is selected? Right now the WebView does not seem to display its contents transparently like every other control so it takes up the entire view and does not show its state as selected.
Also, when the content of the WebView is selected, scrolling down with the track back does not seem to cause the WebView to loose focus. If I continue to scroll down with the track ball, all of a sudden an item in the middle of the ListView gets selected.
I've been searching and looking for this answer for quite some time now. I want to display a little HTML in a webView.
When the User read the HTML, he's supposed to use the back button to go back to the previous activity. However, it closes the App.
How can I make it go back to the last Activity? It would also be ok to display a soft back button or something. Here my code...

I wrote a sample application which displays some test message using webview .The Application has two activities, one activity simply contains a button, when user click on this button , it launch another activity which display the test message on a webview .
I have set setInitialScale() of webview as 150, Now the issue is like, Normally webvbiew displays the content with the scale size 150 (as I set ) but some times it displays the contents with a scale greater than 150.
I overrided the onScaleChanged() function in webViewClient.
In normal case before drawing the content on webview I am getting onScaleChanged() callback ,with the value oldscale as 2 and new scale as 1.5. When issue occurs , I am getting two onScaleChanged() callbacks before drawing the content!!! ,at first I get the onScalechange() callback with oldscale as 2 and new scale as 1.5 , after that getting another onScaleChanged() callback with oldscale as 1.5 and new scale as 2.0 and hence it draws the webview with the scale 2.0 irrespective of setInitialScale() I have given in my application.
This issue happens only in the case if I set setInitialScale() to a value less than device's default webview scale. As per my understanding ,Every device has its own default Scale for webview based on their display property like .075 for ldpi and 1.5 for hdpi etc )
In my device defaultScale for webview is 2, and I set the setInitialScale() as 1.5(150)
normaly webview reset the scale from 2 to 1.5 before draw ( That is from defult to new value ) and it works fine
But some time after changing the scale to 1.5 it reverting back to 2. and issue occurs
public class webActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
[Code].....
I have a user's name and password stored in their preferences.
How do I go about passing it back into the webview in a secure way?
I know if I do this it will work, but it just seems bad. There has to be a better way to post the variables.
webview.loadUrl("http://mysite.com?name="+username+"&password="+somepassword);
I've been looking for days and can't find anything, which make me think I'm missing something obvious.
Step 1: I am subclassing WebView and rendering html content properly. The intial content is very small with a div and image /link This is displayed in a LInear Layout along with a TextView and ListView. That is my first screen/activity of the application.
Step 2: When I click on a link on this webview, it goes through the webViewclient and expands to full screen to fit the content of the requested page.
After Step 2, I am not able to go back to my activity screen once the content is displayed. When I click on the back button to getback to my activity screen close my activity and goes to the phone's applications desktop. (i.e goes out of my application).
Step 3: In order to fix this issue, I stopped setting my own subclasssed WebViewClient. After doing this, the it seems to render the clicked page in a webView as subactivity. Now When I click on backbutton, it goes back to the activity screen. But, the issue now is, I am not catch event when a link is clicked. How can I catch click events in this case.
I have TabHost with custom ListView implemented. My ListView disappears after returning from SMS screen when I try to switch tab (refresh list content).
I have context menu option to send SMS to contact from the list, I start SMS activity there and Im able to return to my app. If I don't type anything in SMS screen, just return immediately everything is fine. List will work. If I type something in SMS and press back key, toast will be displayed: "Your message is saved in Drafts". And now if try to switch tabs, list content disappears.
Debugging revealed that list items are present, and that list adapter constructor is called. However, listAdapters GetView function is never called. And list results are not displayed.

View 3 Replies View RelatedThis is my first android device and i'm loving it... but one thing that irks me is the use, or lack thereof, of the back button.
As I am navigating menus and options in the Settings, I cannot simply go back one menu using the back key. For example, if I go to Settings->Battery Manager->Battery Profile Options and want to go back to the Settings screen, I cannot.
Pushing the back button does nothing and I can only go back to the Settings menu by going Home, then re-entering.
Another quirk regarding the back button is when reading emails. Using a regular email account such as Hotmail, I cannot simply read an email and go back to the inbox using the button.
It makes navigating the phone very tedious.
I'm roooted. I downloaded bootstrap and the first thing i did was create a nandroid back up for my x. then i proceeded to try and install tranquility rom. it got stuck in a bootloop. so when i rebooted into recovery it now goes for some reason to the droid stock recovery and i can't revert back to my back up. what do i do?!
View 4 Replies View RelatedI'm finding that I'm using the back button A LOT whether browsing the web or just navigating the OS. It kind of sucks because the buttons on the droid x are well, really small, and sometimes hard to press because they are so narrow and flimsy feeling. And depending on how you are holding the phone, it could be a good bit of distance for your thumb to travel or I'm finding myself having to reposition the phone in my hands just to reach the back button, which you seem to need very frequently.
Anyone know of any kind of back 'swipe' implementation ? Like some software you can install that makes it if you swipe left to right on maybe the top bar it goes back?
I'm trying to programmatically scroll a WebView to the location of a particular element in the DOM tree. But so far I haven't been able to get the WebView to respond to scroll requests. I've tried calling JavaScript that uses window.scrollTo(...), but the WebView doesn't respond. On the Java side, I've tried calling the WebView.flingScroll(...) method. WebView will respond to flingScroll, but what I need is a scrollTo(...) capability. Any ideas?

There must be a way to do this. How can you tell a ListView that has a header to not scroll it when the user scrolls the contents? I want it to stay in a "stuck" position so that the user can always see what column the content applies to.
