Just 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 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 a problem which is disable and enable scrollView by code. This is my layout which includes header, footer and scrollview. The scrollview contain imageView and MapView. I used scrollview to scroll image and MapView because height total of their larger than height of screen. I want to disable scrollview if I touch map and move in the map. And it is enable when I touch ImageView. So, I will listen even touch and move in the map to enable and disable scrollview.But I try to use setEnable and setHorizontalScrollBarEnabled,setVerticalScrollBar Enabled method to do it but not success.
PHP Code:
<RelativeLayout android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@color/white"
android:orientation="vertical"> <!-- Header --> <RelativeLayout android:id="@+id

How do you disable all touch events in an Android WebView (or scrolling in particular)? I would like the activity to handle all touch events.
View 2 Replies View RelatedOur app (WordPress for Android) uses a scrollview for the new post view, where a user enters in their new blog post. There's quite a few fields on this view, including a large EditText for the post content field.
It appears that when an EditText is in a ScrollView, the ScrollView takes over the scrolling action, so the user can't scroll within the EditText area if they are writing a large post. What can be done so that scrolling will work both within the EditText and the ScrollView?
Here is the layout xml for this view, The EditText that needs the scrolling is @id/content:

View 1 Replies View RelatedI'm trying to make a ScrollView with a list of numbers in it that the user can select from. After the user touches and scrolls, after the finger is lifted I want the scroll to "snap" to the item in the middle of the ScrollView and give me the output. My ScrollView contains a vertical linear layout with TextView objects in it. The ScrollView's vertical size is about 60sp.
I think this would involve the ScrollView.onTouch with a ACTION_UP, but I don't know how to use it. Also, is there a way to get an item's index or value based on a position in the list?
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!

The idea is to control the scrolling via other means and not user touch. i.e. up/down buttons, or random scrolling...
I want to ask that is that possible do in android catch the in the touch mode catch the scrolling direction ? When user touch on the screen left to right, can I catch the change ?
If it is possible which listener can ı use ?

I'm developing a game for Android. It's got a lot going on but is running reasonably smoothly. That is, of course, until the user touches the screen.While they're touching it, onTouchEvent is called (with action = ACTION_MOVE, x = 0 and y = 0) roughly once every ten milliseconds at what appears to be a fairly high priority, as it absolutely obliterates the framerate. As soon as the touch ends the framerate returns to its nice state.Has anyone encountered this? Is there a way to reduce the rate at which ACTION_MOVE events are generated, or to ensure that they're only generated when there is actual movement, or use a polling method that just gets the current location of the touch? Or even just a way to disable it entirely?

Is it possible to detect all touch events in an Activity and capture it and then in return pass that pass event to another View. For example:
Button 1 and Button 2. When Button 1 is pressed I want to capture that touch/click event and automatically pass that touch event to Button 2, basically with one touch/press you get the click generated and that same click is passed on to the second button automatically.
I'm sorry to double post, but this is very important to me. I am making an intranet website that exactly fits the screen of the device it will be used on (Archos 7 home tablet in this case, Android 1.5).
All browsers (default, dolphin, steel, UC) interpret tap&drag on a website as scrolling. I don't want this. Ideally, I want it to be registered as mouse actions. Is there a way to do this?

I'm writing an Android game that needs to receive touch events. My problem is that, whenever the user drags their finger along the screen, so many touch events get sent to the touch event handler (which I think runs as a separate thread) that my frame rate plummets! What's the best way I can limit the number of touch events that are handled per second? For example, if my game runs at 60 fps, I really shouldn't need more than 1 touch event being handled every second. Can I do this is a way that doesn't lose any information (i.e. important information about where on the screen the user touched last)?
View 2 Replies View RelatedI start monkey like this:
monkey -p <MY PACKAGE> --port 4321
(I have already done a tcp port forwarding).
I then use PuTTY to telnet to 127.0.0.1:4321
I can issue a command like tap 100 100 I get a response OK but I see nothing happening on the UI. I have placed a button at that location but I does not receive the touch event.
When I run monkey like this
monkey -p <MY PACKAGE> --pct-touch 100 -v 10
I see touch events being dispatched to the screen.
I'm trying to figure out a way to send touch events to the foreground activity. Essentially I want to write something that allows me to run it from the shell and just say "I touched this co-ordinate", so that I can automate some UI tasks for testing. Essentially what Monkey does, but application agnostic.
I think that android.view.MotionEvent holds the key, but I'm not sure how to run something without view so that I don't interfere with what is on the screen. Perhaps with a service, but I'm unclear how that would work.

Error: "Attempt to read preferences file /data/data/com.android.mms/shared_prefs/com.android.mms_preferences.xml without permission".
Wondering here if there is a way I could trigger an event, so that any library listening for these events (e.g. jQTouch, Sencha touch, iUI, ... ).
If I could extend or use jQuery for such task e.g. $(...).trigger('event') that would be great to know.
Usage example:
I need to debug a few web apps by simulating multi touch with my mouse. This seems a little complicated, so if I could trigger the multi-touch events using Javascript I could therefore test the app more efficiently.
Purpose of the app:
A simple app that draws a circle for every touch recognised on the screen and follows the touch events. On a 'high pressure reading' getPressure (int pointerIndex) the colour of the circle will change and the radius will increase. Additionally the touch ID with getPointerId (int pointerIndex), x- and y-coordinates and pressure are shown next to the finger touch.
Following a code snipplet of the important part (please forgive me it is not the nicest code ;) I know)
CODE:.............
The problem:
A HTC Desire running Android 2.1 is the test platform. The app works fine and tracks two finger without a problem. But it seems that the two touch points interfere with each other when they get t0o close -- it looks like they circles 'snap'to a shared x and y axle. Sometimes they even swap the input coordinates of the other touch event. Another problem is that even though getPressure (int pointerIndex) refers to an PointerID both touch event have the same pressure reading.
As this is all a bit abstract, find a video here: http://www.youtube.com/watch?v=bFxjFexrclU
My question:
Is my code just simply wrong? Does Android 2.1 not handle the touch events well enough get things mixed up?Is this a hardware problem and has nothing to do with 1) and 2)?
I have an Android activity with an ImageButton. I would like to execute some logic when the button is clicked and show a different image for the pressed state, but also receive the touch event on the activity.
By default only the button receives the touch event. If I set the clickable attribute of the button to false then only the activity receives the touch event.
What's the best way to implement the touch event in the activity and the click in the button?
As a work around to the issue where a list item isn't focusable if it has a focusable child item (a comment by Romain Guy was that this was intended behavior, for accessibility reasons) I simply filled the listItem with two children, each of which is focusable - There's nowhere to directly touch on the listItem anymore, just it's children.
For the most part this is a useable workaround, effectively invisible to the user, except for one thing- Although you can scroll by swiping without issue, touching to *stop* the scroll no longer works- I imagine because the child item is capturing the touch event and not passing it to the parent listitem, at least while the scroll is in effect.
Is there a known workaround for this? Perhaps someway to "pass the baton" of the touch event back up to the parent listItem, or a way to change my design?
BTW- I know there's some built-in functonality for single/multiple choice listviews (checkbox listviews) - That doesn't actually help in my case. The app is a contact list, and the row children are a relativelayout (populated with contact info) and a clickable phone icon (a one-touch dial for the contact), which needs to be visible or invisible depending on whether the stored contact has a phone number.

I have a list activity that creates a header row above the data rows from the adapter. I want to receive click events when the user selects the header or a data row (but my data rows have check boxes in them, so this part is tricky). When I use the touch screen, I get this expected behavior:
1. Tapping on any row causes a click event and a dialog appears.
2. Long-pressing on a data row causes a context menu to appear.
3. Long-pressing on the header row does *not* show the context menu.
However, when I use the arrow keys (emulator) or trackball (G1), I get this unexpected behavior:
1. Selecting any row fails to cause any click events, even though the row's appearance changes like it's being clicked.
2. Long-pressing on the header row *does* show the context menu, which I don't want.
3. Occasionally, it doesn't focus the correct row when I move up or down (e.g. it skips from the header to the last data row).
