I would like to have a an app where I can play a bunch of buttons all at the same time using multitouch. The only way I have got it to work is using the touch method and testing for a bunch of x,y coordinates.

I want to know if there is a way to be able to get the touch coordinates in an app. I know of the commands getRawX(),getRawY(),getX(),getY(). But they dont give me the exact coordinates. Shouldnt these coordinates be in the screen resolution range of the phone? or do they have a different range?

Is there API method for android?
I'm trying to get coordinates of the mouse, but there seems to be no easy ways. Can't make the MotionEvent object because the constructor is private. Can anyone please tell me how to get the coordinates of the touch/ pointer/mouse? I only want the touch coordinates of ImageView, but wouldn't mind the touch coordinates anywhere on the screen.

I didn't found any way how to detect coordinates of the touch on RemoteViews.Is anybody aware of some trick how to detect it. Only idea I have is create layout with grid of transparent buttons, put by widget's bitmap as background of such a layout and to every button set PendingIntent.

What I'm wondering is how would I go about mapping the location of the users touch to the coordinates on the image itself, and not the screen?
View 3 Replies View RelatedI've been trying to write a little application that recognizes custom events in Android: you hold your finger over a TextView for a certain length of time, and it changes color.I'm using the MotionEvent coordinates and checking if they are within the bounds of a particular TextView, which is within a table.I am just attaching the onTouch listener to the table within the activity.But I get weird errors: the coordinates seem to be off by one view (i.e. if I touch the view below the view above reacts); or sometimes one will react, and the other will not. Any idea what might be going on?

In Eclipse, when I mouse hover over a built-in method, it displays a method definition including stuff like what the method does, input objects, return objects etc. If I have a yellow line (warning) under the method I'm trying to use, I can't get the mouse-over to show the definition. If I try hitting F3, I get a "The Jar of this class file belongs to container "Android 1.6" How do I show the definition of the method I am using when there is a warning?

View 4 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..

View 3 Replies View RelatedI'm currently developing an app which uses tabs and google map. What I want to do is to get the gps positions, say 3, and store them in sql db (which I'm already doing) and then display them on the map. I already created canvas, added to overlay but those points disappear when I'm changing tabs so I thought if there is a way to somehow store those coords with google map so I can retrieve them and display them nicely whenever I'm clicking the "map tab"? Please can anyone help?

I'd like to be able to access the GPS coordinates in Javascript inside a browser window.
Now I could simply send the GPS coords to the server and read from within the browser window by reading off the server, but I was wondering if there was any way to send the GPS coordinates from the device straight into the browser window without having to go through a remote server?
It would be really great to be able to access the GPS coordinates directly from http://10.0.2.2:9999

I'm trying to get the absolute screen pixel coordinates of the top left corner of a view. However, all methods I can find such as getLeft() and getRight() don't work as they all seem to be relative to the parent of the view, thus giving me 0. What is the proper way to do this?
If it helps, this is for a 'put the picture back in order' game. I want the user to be able to draw a box to select multiple pieces. My assumption is that the easiest way to do that is to getRawX() and getRawY() from the MotionEvent and then compare those values against the top left corner of the layout holding the pieces. Knowing the size of the pieces, I can then determine how many pieces have been selected. I realise I can use getX() and getY() on the MotionEvent, but as that returns a relative position that makes determining which pieces were selected more difficult. (Not impossible, I know, but it seems unnecessarily complicated).

View 2 Replies View RelatedMy question in a nutshell is: Is there a correlation between the number of decimals used in GPS co-ordinates and the accuracy of the location?
Right now I happen to be working with the Android SDK but I'm sure this question can apply to many other geolocation SDKs. Basically, Android returns GPS coordinates with up to 14 digits. That seems like overkill in most situations. Lets say I needed accuracy down to about an area of 10 feet by 10 feet. How many decimals do I really need to worry about? The use-case that I'm looking for is I want to know if a person is north or south of a particular latitude - how many digits would I need to store in the database and how many digits would I need to compare?
