I am writing a game using OPENGL, there are several 3D objects in my surface view. My question is: Should each 3D object implement view in order to get touch events? Or there is other way to do this?

I've never built a game before, and I've not programmed for Android before but am looking to do so over the summer by building a game. What type of object do I use for a shape that I want the user to be able to drag around the screen for instance using touch gestures? How do I tie together the MotionEvent, View and Graphics2D to make objects drawn on screen that can be interacted with? I imagine this will use ActionListeners / Handlers but I'm a bit confused at this stage.

Imagine I've drawn a cube. I want that user can push his finger over the cube and can rotate the cube and move it around the screen.
Is there any way to do that?
How can assign an event listener to touch and move events only when the user touch the cube?
UPDATE I want something like this: Rotate cube with fingers.
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 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)?

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.
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?
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 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 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).
I'm developing an HTML/Javascript mobile web application using Dashcode. Normally I wouldn't use such WYSIWYG stuff, but I've found it a very rapid development process.
Unfortunately it seems like I can't get it to run on Android's browser currently. The main display loads and all the correct data is pulled from web services, but you cannot press on anything to activate it.
I suspect that the android browser is sending different javascript events, which the Dashcode objects are not configured to pick up.
In addition, the adb logcat debugger refuses to output any log messages from the browser on the emulator, and as such I'm having a very hard time sorting this out.
What events I need to be watching for, so I can iterate over all the touch handlers and duplicate them for the android events, or offer help in any other way on this situation?
I have an activity defined as:

I have a custom Android view which overrides onTouchEvent(MotionEvent) to handle horizontal scrolling of content within the view. However, when the ScrollView in which this is contained scrolls vertically, the custom view stops receiving touch events. Ideally what I want is for the custom view to continue receiving events so it can handle its own horizontal scrolling, while the containing view hierarchy deals with vertical scrolling.
Is there any way to continue receiving those motion events on scroll? If not, is there any other way to get the touch events I need?
My phones' display has been broken and I would like to know if there is a pc software that allows me to simulate touch events via adb bridge.
View 1 Replies View RelatedThe FAQ mentions a method of passing objects around activities. (It is not clear to me): "A HashMap of WeakReferences to Objects. You can also use a HashMap of WeakReferences to Objects with Long keys. When an activity wants to pass an object to another activity, it simply puts the object in the map and sends the key (which is a unique Long based on a counter or time stamp) to the recipient activity via intent extras. The recipient activity retrieves the object using this key.".................
View 7 Replies View RelatedI have an application that have a Google map on Google Android 1.5 since we have been working on the application for a long time, we are not in stage of upgrading to the newest framework, so we are using 1.5. Now, I have map locations that are dynamically generated and drawn on the map at run-time to visualize some streams, Up to this point the application is working fine, Now my problem is that I am trying to filter the objects ( addresses) to visualize only the on-screen ones. I do NOT want to visualize the addresses that are off-screen. The way I am trying to do this is to check the screen-coordinates of each object (address) before visualizing it, then it the coordinates (x,y) more than (0,0) and less than (320, 460). I should visualize it. I am trying to use this approach, but it is not working for some reasons, I have tried many posts but could not understand why, there must be something missing somewhere that I am not aware of.
View 11 Replies View RelatedOn iPhone, iPod touch and (presumably) iPad, Apple has multi-touch event handling available via JavaScript in Mobile Safari. I know the Nexus One recently added multi-touch support via an update, and I believe webOS is also multi-touch enabled. Do Android 2.1 and/or webOS have access to multi-touch in the browser, or is this currently exclusive to Apple devices?

View 4 Replies View RelatedI am trying to pass the same touch events on one widget to the other so they both scroll at the same time and in same way. I have two Gallery widgets one above and one below. If the above one is scrolled then I want to pass the same touch event to the bottom widget so it also scrolls the same way.I have tried to use dispatchtouchevent events but I am facing an issue where in if the bottom gallery widget has some edit text then the edit text gets the key event and both widgets doesnt scroll anymore.I have tried to set focussable and editable to false on edittext even then it gets the touch events.I think I am going in the right direction. However I need some assistance in doing the right way.
View 3 Replies View RelatedIs there a way to make highlighting of a row in a listview delayed if the user is simply scrolling the list with their finger? To clarify, when the user puts their finger down to scroll, the intersected row (if any) gets highlighted for a short moment, before it realizes the user is just trying to scroll (then the highlight turns off). It seems like the timeout is too short - iPhone has the same behavior, just seems that the timeout is longer to discern between a real row- select-touch, and just a scroll-touch. Any way to tweak this? You can see the behavior in any of the system apps that have lists..

But, here, we call A.class; My concern is that i don't want to call on Create(),nor do i want to push UI screen I just want to make 1 static object for 1 screen;and want to manage it throughout my application. that is, instead of calling A.class; can i call A a = new A(),and manage that object without pushing,and whenever i need i push that screen. Is there someway?

View 2 Replies View RelatedIs there a way to pass an Array List of objects between activities? The myObject implements Parcelable and I'm able to successfully pass the objects around individually, but that means I need to have an exact amount of "myObjects" coded. I want this to dynamically grow/shrink by what the user does with the app. I have seen some posts on the web about doing:
Activity A
ArrayList<myObject> myObjArray = new ArrayList<myObject>();
Then when passing this into the intent I would use:
intent.putParcelableArrayListExtra("myObjArray", myObjArray);
Activity B
ArrayList<myObject> myObjArray = new ArrayList<myObject>();
Bundle extras = getIntent().getExtras(); myObjArray = extras.getParcelableArray("myObjArray");
However, the myObjArray always gets filled with "null". How can I achieve this?
I want to pass an object from Activity B to Activity A. Scenario:
- Activity A calls Activity B
- User selects item in Activity B
- Activity B passes an object to Activity A
How do I accomplish this? And in which method do I read in the passed object in Activity A?
I am new to this android stuff and SQLlite etc.I am going to log some numbers at a certain interval, and will put them into a dynamic histogram, by dynamic i mean that there will be a maximum number of samples in the histogram, the histogram and age stuff should be persisted either in db or plain file.For simplicity, I would like the samples to be stored in a blob type datafield, but i cannot se if this is possible. Alternative i could have another table with the samples Or I could simply have files with filename = name and content = samples.my concern might be unclear by now, but put simply, what is most effecient regarding power usage?
