I included a WebView in my activity and load some Javascript in it which is then going to get data from an external website.This works and displays fine but the problem is that my activity doesn't scroll when the WebView is done loading so I can't see the bottom of the WebView such as all the other Views I put below this.

Until now I have been an iPhone developer only and now I have decided to give Android a whirl. Something I haven't been able to figure out on Android is how to programmatically prevent scrolling in a webview?? Something similar to iPhones prevention of the onTouchMove event would be great!
View 3 Replies View RelatedI am showing a RSS feed in my application using Webview as ListItem and it works great except that it is very sluggish at times. Since I don't know the size of the content then I can't set the height of each Webview and therefore I have the following code (this is the code for a single ListItem)...
But the "wrap_content" causes the Webview to readjust size when scrolling. The scrollbar-indicator of the listview also has problems knowing the size of the complete list so it changes size when scrolling. All this causes a very "jerky" experience when scrolling.
Is there any better way of doing this?
I have a webview in a scrollview. Webview displays my text. I have a searching feature also. It highlights my searched term. Now I want to scroll to that searched string. It should automatically scroll to that searched term. How can I do that? I tried with methods like scrollTo and scrollBy. They will not work as I cannot get the coordinates of searched term.

View 1 Replies View RelatedI have an activity that begins with almost a page of text, then has a few form controls. When the activity launches, the first form control takes focus and the screen scrolls down to make it fully visible. When this happens, the text at the top is off the top edge of the screen. When the screen comes into view, I want the text at the top to be visible. So, onCreate, I tried sending a message to the Activity's overridden handler to do the following:
ScrollView main = (ScrollView) findViewById(R.id.main);
main.pageScroll(ScrollView.FOCUS_UP);
This did nothing. I then tried:
main.scrollTo(0,0); This also did nothing.
I then tried sending the message from onResume instead of onCreate. This also did nothing. How to force the scrollview to actually scroll?
is it possible that a user clicks inside a webview on a link like <a href/> and then my activity is opened? I need this for sms, email, telephone and some specials. Lets say the user browses on the impressum and clicks on the phone number for support. I want the phone to call that number.Or lets say the browser clicks on an image (with a special href?), and I want the user to land on my picture-view-activity.

I've been searching and looking for this answer for quite some time now. I want to display a little HTML in a webView.

View 2 Replies View RelatedIn my app I have to load external page into WebView-based activity. Some of my users with slower connections are reporting screen timeout while waiting for the page to load. What would be a good way of loading the page on backgorund thread and then refreshing the screen? Use HttpClient to fetch it and then use WebView#loadData? My fear is - the page I'm loading is pretty complicated there's some JS that happens on load - wouldn't I just mess it up? Is there an alternative way of doing what I need?
View 5 Replies View RelatedI launch my TestWebView activity. After my web page is loaded, I put the app in the background by pressing the Home key. Then I bring the TestWebActivity back to the foreground. Unexpectedly, TestWebView's onCreate() is called when I bring the activity to the foreground. But onDestroy is never called. This same thing happens every time I tested. It appears the old TestWebView was not completely killed so there are possibly duplicate web clients running.

I am experimenting with using a WebView to display Flash content inside my activity. Everything is working pretty well, but when the user hits the home key to put the activity into the background, the Flash content keeps running (sound keeps playing, etc)
I have noticed that both the stock Android browser and Dolphin Browser seem to avoid this problem, and properly pause the Flash content when the browsing activity is put into the background.
Ideally I would like a solution that kills the WebView completely if the activity is finishing, but pauses it otherwise (basically copying the default behavior of the browser)
Here is a simple test I put together that loads a game on Kongregate which has some background music:
CODE:..............
I took a look at the latest source for the stock browser, and it seems to be doing something similar (calling pauseTimers/resumeTimers), although I fear the code I have been looking at is out of date, because it is calling functions that don't seem to exist anymore.
I did verify that the call to pauseTimers is working by testing with a simple JavaScript setInterval which updates a counter. Is there something else obvious that I should be trying in regard to Window or View management?
The documentation for the mobile Flash player says:
Flash Player will also automatically pause SWF playback it is not in view or the foreground application, for example when a call is received or alarm goes off, to reduce CPU utilization, battery usage and memory usage.
This seems to be working perfectly in both the stock browser and Dolphin Browser, but not in my app. Any ideas/solutions would be greatly appreciated!
Update: Here is the function we ended up adding to our activity to get this to work. We call it with "onPause" in the activity's onPause function and "onResume" in the activity's onResume function:

Is there a way to retrieve Browser's user-agent without having a WebView in activity?
I know it is possible to get it via WebView:
WebView view = (WebView) findViewById(R.id.someview);
String ua = view.getSettings().getUserAgentString() ;
But in my case I don't have/need a webview object and I don't want to create it just for retrieving user-agent string.
I am having issue while showing a WebView in an activity in the middle of the screen. I have an activity and I want to show a webview in the center of screen. My activity is transparent so background activity will be visible. Whenever I try to create a webview and add it to activity using setContentView(webview) it always shows the view on the top left corner of the screen. Is their a way to workaround this?I am trying to do this via pure code only.
Here is my code.
CODE:....................
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 a library-only Android eclipse project (no main class, only library classes) that I want to include in my main Android Application project. I went to the Build Path and added the library project to the "Required projects on the build path" on the Projects tab, and checked it on the "Order and Export" tab. However, when the application is run, it emits VerifyError exception, because the class from the library project didn't happen to be packaged together in the apk.
View 1 Replies View RelatedIn my Android app, I always get VerifyErrors! And I cannot figure out why. Whenever I include a external JAR, I always get VerifyErrors when I try to launch my app (except for once, when I included Apache Log4j.) I usually get around this by taking the source of the library and adding it to my project, but I am trying to put the GData client library (http://code.google.com/p/gdata-java-client/). I can get this in source, but it's dependencies (mail.jar, activation.jar, servlet-api.jar) I cannot, so I get verify errors. I would like to get to the root of this problem once and for all. I looked on the internet, but they all seem to talk about incomplete class files? which I do not know of.

View 2 Replies View Relatedi'm trying to include a maven java project into my android project. the maven project is the greader-unofficial project which allows developers access to google reader accounts, and handles all of the http transactions and URI/URL building, making grabbing feeds and items from google reader transparent to the developer. the project is available here:
the code is originally written for the standard jdk and uses classes from java.net that are not a part of the standard Android SDK. i actually tried to manually resolve all dependencies and ran into a problem when i got as far as including com.sun.syndication pieces required by the class be.lechtitseb.google.reader.api.util.AtomUtil.java... some of the classes in java.net that are in the standard jdk (i'm using 1.6) are not in the Android SDK. in addition, resolving all of these dependencies manually is just ridiculous when i'm compiling a maven project that should be pretty simple.
however, i can use maven to compile the sources with no issue. how can i include this maven project, which is dependent on the complete jdk, into my android project in such a way that it will compile so that i can access the GoogleReader class from my android project? and for the record, i don't have the expertise to rewrite this entire api to work with the standard Android SDK.
The app I'm working on has 4 tabs, 3 of which share many features, including a navigation bar a the bottom with Back, Edit, and Map buttons. There is exactly the same xml in all 3 layouts, so I'm trying to DRY this out by extracting that xml into a separate component, including it, and then going from there. Previously I had:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/showedit_toolbar" style="@style/showItemToolbar">
<ImageButton android:id="@+id/show_person_back_button"
style="@style/blackToolbarButton"
android:src="@drawable/left_white_arrow"
android:layout_alignParentLeft="true"/>
<Button android:id="@+id/show_person_map_button"
style="@style/blackToolbarButton"
android:text="map" android:layout_alignParentRight="true"/>
<Button android:id="@+id/show_person_edit_button"
style="@style/blackToolbarButton"
android:text="edit" android:layout_toLeftOf="@id/show_person_map_button"/>
</RelativeLayout>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:layout_above="@id/showedit_toolbar"
style="@style/CoinLightTheme">
// Lots more layout omitted
I extracted out the bit that's repeated into an xml file called show_toolbar.xml, changing the names of variables to make it more generic across the 3 views
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/show_toolbar" style="@style/showItemToolbar">
<ImageButton style="@style/blackToolbarButton"
android:src="@drawable/left_white_arrow"
android:layout_alignParentLeft="true"
android:id="@+id/show_back_button"/>
<Button android:id="@+id/show_map_button"
style="@style/blackToolbarButton"
android:text="map" android:layout_alignParentRight="true"/>
<Button android:id="@+id/show_edit_button" style="@style/blackToolbarButton"
android:text="edit" android:layout_toLeftOf="@id/show_map_button"/>
</RelativeLayout>
Then from within my original layout file, I replaced that big block of code with
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent" android:layout_width="fill_parent">
<include android:id="@+id/show_toolbar" layout="@layout/show_toolbar"/>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent" android:layout_width="fill_parent"
android:layout_above="@id/showedit_toolbar" style="@style/CoinLightTheme">
Now, the problem is that the view no longer shows up. Including Custom component causes it to be hidden behind main viewI can still click the buttons and they respond (i.e. if I click in the corner where the button should be, it still works), but I cannot see the buttons or bar onto which they were drawn. I cannot find very good documentation on how Include is supposed to work, so perhaps I am using it incorrectly.
I picked up a Zeki TB782B for my kids to use and I have been really happy with it as an entertainment tablet. I have put my daughters gmail account into it and gmail works great, but contacts app does not show up anywhere including apps.
