This is a logic based problem where I will need a small sample of code or an idea supplied for an answer.<\/p>\n

I am creating a U.I. programmatically from a JSON<\/code> response. This app will load in an unknown amount of questions and answers. I’m using loops and conditional statements to create the Views<\/code> for the U.I. and I am using an AsyncTask<\/code> for most of the heavy lifting.<\/p>\n

Well the problem I can’t seem to figure out is: How will I give an unknown amount of views unique<\/strong> id’s so that I can use them.<\/p>\n

I probably went about this the wrong way to begin with, however this is where I’m at. I will need to give the EditText<\/code> an id to grab user input, I will need to give the ImageButton<\/code> and id so it can perform events with the onClick<\/code> function, and so on and so forth. You get the point I’m sure. So how would one of you tackle this problem?<\/p>\n
    \n
  1. \n
    It’s really hard to answer this question. It really depends on what you want to do with the captured data. In any case, you don’t have to generated IDs for the elements, you can set new event listeners using Anonymous classes. Then, each of these listeners can save your data to somewhere<\/em> depending on your key (name?).<\/p>\n<\/li>\n<\/ol>\n
