Hey Oliver,
I'm just starting out on the Android (and Java) and was trying to
solve a very similar problem and gain access to clicks on a series of
ImageView objects when I stumbled across your post. I ended up solving
my problem and thought maybe it would help you also.
I'm putting together a card game, setup ImageView objects for each of
the 5 cards on the display. I wanted to get a click on any card and be
able to determine which card was clicked.
The views are defined as:
ImageView[] ImageCards = new ImageView[5];
I then borrowed from your example a bit and did this:
// Create an anonymous implementation of OnClickListener
private OnClickListener mCorkyListener = new OnClickListener() {
public void onClick(View v)
{
int cnt;
ImageView iv;
iv = (ImageView) v; // Get the View that was
clicked
// Find which card was clicked by walking through our
cardviews comparing to the one that was clicked
for(cnt=0;cnt<5;cnt++)
{
if( iv == ImageCards[cnt] )
{
// We found which card was clicked, go
display it to our debug console just for testing
System.out.format("Click on card %d%n", cnt);
}
}
}
};
// Next, in my main onCreate section
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Setup the handles for the individual card's imageviews
ImageCards[0] = (ImageView) findViewById(R.id.CardView1); //
CardViewx as defined in main.xml
ImageCards[1] = (ImageView) findViewById(R.id.CardView2);
ImageCards[2] = (ImageView) findViewById(R.id.CardView3);
ImageCards[3] = (ImageView) findViewById(R.id.CardView4);
ImageCards[4] = (ImageView) findViewById(R.id.CardView5);
// Connect each view to our private OnClickListener
int cnt;
for(cnt=0;cnt<5;cnt++)
{
ImageCards[cnt].setOnClickListener(mCorkyListener);
}
I'm sure it could be architected cleaner but this works like a
charm.... hard to argue with something that works when you're just
starting out!
