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 ?

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)?

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.

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.............

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.

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.

I like to know using which version of Android SDK we can develop multi touch handling. Does Android SDK 1.6 support multi touch? If yes, can i get some sample code, where i can have multiple imagebuttons placed on screen and clicking on all the imagebuttons at a time should detect multiple touch events?

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.

Just want to start out by saying this seems like a great site, hope you guys can help! I'm trying to use the structure laid out in LunarLander to create a simple game in which the user can drag some bitmaps around on the screen (the actual game is more complex, but that's not important).

Is 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..

I purchased the IR overlay from here [URL] I got it working with my mk808b by using an idc fiile, however, it only allows one touch point which means no zoom. On the computer it is multitouch.
