I have an app Ive been working on where I have moving onscreen objects that are drawn and updated each frame to a canvas which is then drawn to a view. The objects are kept in in a listArray and when a user clicks on the screen its registered in the view and then passed through to the class I use as my background loop that keeps track of everything that needs to be drawn onscreen. I have a method in that data class that parses through all the objects and compares the x,y coordinates to those of the onscreen click and sometimes this works and sometimes it doesnt. Right now I limit the amount of objects in memory to about 80 and sometimes its possible that up to 30 or more are onscreen at once. I also have a method that goes through the objects in memory and changes a boolean value which tells the data class whether or not the objects should be considered active or clickable.
My problems: As for the method that checks if the objects are clickable, for some reason most of the objects are always set to active when in the logcat the numbers indicate that they should not be. Also the way that I am trying to register screen clicks is not reliable. Sometimes its accurate and sometimes its not and sometimes it doesnt work at all. When I debug and watch the x,y's they all match up and the object is marked as active which means it my data class should handle a click associated with that object but it only lines up half the time. So.....I was wondering how I could go about creating a class that possibly extended or implemented the functionality of a button or view so that it can individually handle clicks and have its graphical representation drawn into a view. I have tried this by extending ImageButton however When I tried drawing the images to the canvas and then updated it in each frame the objects would no longer move freely and were all drawn in the upper right hand corner of the screen. That tells me that somewhere between my data class and the view that I had some disconnect and misunderstanding in the way to go about handling this. So has anyone ever handled something like this? My project is already complex enough and I dont want to go about using some game engine or somthing just to accomplish one portion of my app. Everything else works great except the way I am handling screen clicks to the objects. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
