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.

Samsung Moment :: HTC Touch Input Keyboard

Dec 11, 2009

this keyboard is light years ahead of the default virtual qwerty.I bought the Moment for the hard qwerty and absolutely love it, but hated to have to open the phone for each and every little thing due to the god-awful virtual keyboard.Installing HTC's Touch Input was the best decision I've made. It's super responsive and typing is almost as easy as with the iPhone. I use the T9 numeric as opposed to the full qwerty. There's also a compact qwerty if that's your thing (Blackberry-esque)It's not on the Market AFAIK, but a quick google search will show you where it is. Even has a calibration tool!

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 :: 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 : 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 :: 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.............

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.

Android :: Draw Transparent Lines On Bitmap Via Touch Input

Jul 23, 2010

I am working on a paint application for Android. Now I want to implement an eraser to allow erasing parts of a loaded bitmap by using touch input and making the bitmap transparent along the finger's path.

A very good example of what I try to achieve is shown in the application Steamy Window for Android. Steamy Window simulates a fogged window, where a user can wipe parts of the fog via touch input.

UPDATE: I have posted the most important sections of my current code below. I am not really happy with it for the following reasons:

Drawing is quite sluggish. What can I improve here?
I am looking for a way to use an alpha mask in order to set the pixel transparency/alpha of the pixels as I want to simulate a paint brush. Any suggestions how this could be achieved?
