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!

Is there a way to intercept a certain Toast and prevent it from showing up?
View 2 Replies View RelatedI am trying to make a non-editable EditText that is placed in a ScrollView and scrolling is controlled programmatically (when a left/right fling is detected).
Here's my simple layout:
CODE:..........
And here is my simple program:
CODE:.............
So, to explain it simply, I have two custom simplegesture classes that I attached to the EditText and the ScrollView. For the EditText, I'm trying to detect a left/right fling and when detected, I'm scrolling the it up 1 page up/down. The custom simplegesture attached to the ScrollView is to disable finger scrolling.
Here's a screen shot after a right fling was done: http://img830.imageshack.us/i/textcut.png/
I kinda works right now but I have two questions:
How do I control the scroll so that lines won't get "cut-off" (please refer to the picture above where the first line on the screen is a bit "cuf-off"). Why when I scroll the page up/down programmatically, the EditText is auto select-all (please refer to the picture above where the whole screen turns orange after scrolling)? Why when I changed MyGestureDetector to detect fling on the Y-axis (vertical fling) and programmatically scroll the EditText, it doesnt' work? It wouldn't work even if I made the change in ScrollGestureDetector too. Does it have something to do with the behaviour of the ScrollView?
I have set an activity containing a webview which loads a page from the network. Each time the orientation of the screen changes the oncreate(...) method is called and the webview reloads its content again. Is there a way to avoid the webview to reload the web page?
View 3 Replies View RelatedJust wondering if there is an easier way to simply stop ScrollView from being scrolled via touch inputs? I will programmatically get the ScrollView to scroll to top or bottom.
As a last resort, I guess I will have to inherit from ScrollView and capture all the ontouch events. But wondering if there is an easier way before I take this approach?
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.
View 2 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 3 Replies View RelatedI'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?

So...how can I prevent this? is there anyway that I can free memory when starting the app? can I tell the system to free memory before loading the image?

View 2 Replies View RelatedMy app builds up a custom screen as dictated to me via the users 'application'. This means that I can end up in the situation where I have a parent scrollview and somewhere down the heirachy I can have a listView or a multiline TextView. Both of these scenarios continue to work fine under 2.1, however are broken in 2.2 (both device and emulator). The symptoms are that the child (list or textview) is unable to scroll using touch gestures although they can be scrolled using the keypad. Has anyone else experienced this behaviour and/or have a work around?? It appears that the onTouchEvent function in View has been changed substantially but I am currently delving into the code...

View 2 Replies View RelatedI'm trying to make a layout that is something similar to how the android market is...where say under comments there is what appears to be a ListView but it does not scroll (the whole page scroll but not the comments). I'm not sure if its even a ListView but I want something that looks like the list view (ie. have those divider bars and what not but NOT SCROLLABLE). There are people suggesting to use a LinearLayout instead of a ListView but I also what the items to be clickable and open a new activity. Please help?
My current layout tree is like so
<LinearLayout>
<ScrollView>
<RelativeLayout>
I am looking to put content inside the RelativeLayout.
Just wondering if anyone knows of a way to invert scrolling so that you swipe down-to-go-down and up-to-go-up instead of the way it is by default: up-to-go-down and down-to-go-up?The only reason it's a problem for me is that I have a laptop and use two-finger-scrolling on the trackpad (down-to-go-down/up-to-go-up). This means that when I switch from one to the other, I keep trying to go the wring way with my swipes. Confusing. I looked through all of the settings on the phone and tried googling and looking through the available apps but to no avail.
View 2 Replies View RelatedI have a gallery and when a image is selected, I want to start new thread (for loading other images). But I don't want to do it while the gallery is scrolling. How can I know the state of the gallery and if it is still scrolling? I can't use "setCallbackDuringFling(false)" because I have a textview under the image that has to be updated during the scrolling.
View 2 Replies View RelatedI have a list Activity 4 which i have extended the BaseAdapter and the getview looks like this.
public View getView(int position, View convertView, ViewGroup parent) {
View row=null;
for(int i=0;i<10; {
row = convertView;
if(row==null) {
LayoutInflater inflater = mContext.getLayoutInflater();
row = inflater.inflate(R.layout.parsed,null); }
TextView id = (TextView)row.findViewById(R.id.id);
id.setText(idvector.elementAt(position));
TextView photo = (TextView)row.findViewById(R.id.photo);....
I have a ListView with custom rows. When any of these rows is clicked, the ListView's data is regenerated. I'd like the list to scroll back to the top when this happens.
I initially tried using setSelection(0) in each row's OnClickListener to achieve this but was unsuccessful (I believe because the ListView loses its scroll position when its data is invalidated - so my call to
setSelection is undone. I still don't understand how the ListView decides where to scroll to after invalidation, though).
The only working solution I know of was given by Romain Guy here: http://groups.google.com/group/android-developers/browse_thread/thread/127ca57414035301
It involves (View.post)ing the call to _listView.setSelection(0). I found this to perform quite poorly.
The newly generated list shows up with its scroll location unchanged and there is a considerable delay before it scrolls back to the top.
Is there any better way to achieve this functionality?
In one of my projects I've got a ListView with hundreds of elements. But when scrolling through this list I get the following error:
CODE:.....................
I currently have one Scrollview which contains a table layout and one list in my activity. Now my problem is that I wanted to move both of them(Scrollview and list) together and with proper synchronization...
So if scrollview is being scrolled then listview should also scroll with the same distance, and vice versa...
I'm currently working on a game for android.
I have three ImageView's next to each other, they're positioned next to each other using the "android:layout_toRightOf". The views are located within a RelativeLayout tag. Each of these views are centered into the middle of the screen using "android:scaleType="fitCenter"" and they fill the entire screen.
I'm attempting to implement a horizontal scroll from one view to another so that I basically get one view on my screen at a time.
Here is the code that I'm currently using
CODE:................
What I'm currently getting is three images next to each other -- but sometimes they take up less then an entire screen. I want both the left and right padding to be correct, so that I can only see one image at a time.
I have an ImageView that is twice the height of a normale screen ( 960 dip). I would like to scroll it nicely up and down on the screen. The bottom of the screen should contain a bottom. I have tried various combinations of ScrollView and Imageviews without any success. I have also thinkered with the :isScrollContainer attribute without results. Anyone knows how to do this?

View 1 Replies View RelatedI was wondering what the most effective way of preventing people from stealing my application (downloading a copy of the .apk online rather than buying it).I've spent a lot of time on one in particular (Droidbox) and won't be releasing Sync until I can guarantee that the people who are providing illegal copies of the pro version aren't able to.Anyone implemented this? I've tried checking my package signature verses an the signature of an unsigned copy but it appears to be the same - perhaps I'm doing something incorrectly here. I'm unsure whether people actually distribute the signed .apk in which case I don't think signature validation would work to begin with.Please note, this question is specific to Android Marketplace Applications - the difference being, application delivery is out of my hands and I have no way of linking between a legitimate purchase and an illegal download.

View 3 Replies View RelatedIs there an app (or better, a way within Android) to prevent the same contact from showing the the call log more than once? I talk mainly to the same few people, with a few others scattered between, and it would be nice if I had the option to see each contact only once in the call log. (Maybe have the call times viewable if I open the contact's entry in the call log.)
