Re: [android-developers] Getting hold of a resource using generated string

Try Resources#getIdentifier().

 Ok, here's the problem. I have a layout file with 25 ImageButtons in in
 laid out in a 5x5 grid. During my application setup, I need to go
 through and add onClick and onLongClick handlers to each button and add
 the buttons to a local array. The problem is, I don't want to explicitly
 name every button in code. It's error prone. I want to do this setup in
 a loop. I thought I could do something like the following:

 int buttonBaseId = com.pingo.R.Id.button00;
 ImageButton button = null;
 for (int i = 0; i  R.attr.GRID_SIZE; ++i) {
 for (int j = 0; j  R.attr.GRID_SIZE; ++j) {
 button = (ImageButton) findViewById(buttonBaseId++);
 setupButton(button,i,j);
 }
 }

 But that doesn't work. I get the error:

 DescriptionResourcePathLocationType
 The type com.pingo.R$Id cannot be resolved. It is indirectly referenced
 from required .class filesMain.java/Pingo/src/com/pingoline
 1Java Problem

 What I would prefer would be some way to get the buttons like:


 int buttonBaseId = com.pingo.R.Id.button00;
 ImageButton button = null;
 for (int i = 0; i  R.attr.GRID_SIZE; ++i) {
 for (int j = 0; j  R.attr.GRID_SIZE; ++j) {
 String idString = button + i + j;
 button = (ImageButton) findViewByIdString(idString);
 setupButton(button,i,j);
 }
 }

 Suggestions?

 Thanks,
   Ray

Alternatively, you could just create and set up these 25 buttons in code.

for (int i = 0; i  R.attr.GRID_SIZE; ++i) {
 for (int j = 0; j  R.attr.GRID_SIZE; ++j) {
 ImageButton button = new ImageButton(this);
 setupButton(button,i,j);
 }
 }

Thank you. I knew there had to be a way.
