Android : Get Co-ordinates Of A Touch Event On Droid?

May 30, 2010

I'm new to Android, I've followed the hello world tutorial through and have a basic idea of what's going on. I'm particularly interested in the touch screen of my T-Mobile Pulse so just to get me started I want to be able to write the co-ordinates of a tocuh event on the screen, so say the user touched the co-ordinate 5,2 - a textview on the screen would display that.

At present I have a simple program that just loads an xml file which contains the textview I intend to write the co-ordinates in.

Thank you in advance, I did Google for help and searched stackoverflow but everything I found either went way over my head or wasn't suitable for this.

Android :: Get Touch Event In Any View (droid)?

Oct 19, 2010

I need to make a service that capture all touch events, not in a specific view or when an specific activity is open. This service is started when the boot is completed (and I have an app to stop/play this service when I want it). So it write something (in a Toast) when the user touch any place in the screen.

Can I do this? Or only in specifics things (with OnTouchListener and adding specifics views, for example)?

Android : How To Avoid Touch Event

Aug 19, 2009

I am trying to use "setClickable(false)" + "setLongClickable(false)" + "setFocusableInTouchMode(false)" to disable Touch Event for every views but failed. When mouse clicks, OnTouchEvent() of some view will still be called. What I want is only to disable Touch event because my application need not Touch and Touch event will disturb the running of app. Is there any way to disable Touch ?

Android :: Touch Or Click Event With ListView Containing GridView

Nov 10, 2009

Here is my problem : I have a view containing a listView. And each row of this listview is composed of a linearLayout, itself composed of three textview and a gridView. Here is a summary of my layout for one row:

......

I want to perform an action when the user click anywere on an item of the listview. So I try these two approaches on the listview : - myActivity.getListView().setOnTouchListener(new View.OnTouchListener () {...}) - myActivity.getListView().setOnItemClickListener(new AdapterView.OnItemClickListener() { ...}) And here is the trouble : - when I click on the textview, it nearly works : the touch listener is called, but not the clicklistener - when I click on the gridView it doesn't work....the event is just dispatched to the element of the gridView.............

Android :: Need System - Wide Touch Event Application

Sep 5, 2010

I'd like to receive a TouchEvent in my Android application any time the screen is touched. Even if my application is not in focus.Is there an general even listener or intent filter I can write to achieve this? The goal is to write system wide gesture engine. So for example, if the user swiped up and then down, a certain application would be launched regardless of where the user is.

Android :: Keyboard Input - Touch Event Noisy

Jul 21, 2010

I'm working on a simple game: when you press a button on the screen, a character will run to certain direction. It's easy to support keyboard input. But, some phone doesn't go with a keyboard or even no a track ball. So I decided to draw a virtual "run" key on the screen (with opengl). When the user press the virtual key, I apply a velocity to the character. And when the user release the key, I disable the velocity to stop the character but there seems to be some touch event noisy. If my finger cannot press still, I will see millions of touch down and touch up events, instead of a single long pressing.

And occasionally, my program captured the touch down event when I touch the screen, but didn't capture touch up event. So my character will keep moving, even no finger is on the screen. I'm wondering if there is some way to reduce the touch event noisy and tell if the user is currently pressing on the screen, instead of only getting an event when touch up and down happen. It seems the system UI can detect long pressing, for example when you put a finger on one item of the list view widget, the entire item turns to orange. I just don't know how to detect pressing in my opengl game.

Android :: How To Make Listview With Selectable Children Stop Scrolling On Touch Event

Oct 20, 2009

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'm developing an Android application with OpenGL and JNI (all OpenGL stuff is in C code).

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.
