Hello,

We recently added a scrollable list as part of the ketai.ui package. Check it out here:

Any feedback is greatly appreciated.

thanks,

Like with AWT and Swing, native Android GUI components cannot be integrated into a Processing sketch. Your best bet, as mentioned above, is to use Ketai.

Hello mataarsak,

Check the UI example that comes in the package. It shows usage of the basic UI components exposed by the library.

http://code.google.com/p/ketai/source/browse/trunk/ketai/examples/UI/UI.pde

Create the instance of KetaiList passing in an ArrayList<String> and use the

onKetaiListSelection(KetaiList klist)  

callback for handling a selection.

good luck!,

thank you so much , I added this code :

void onBackPressed() {

}

void keyPressed() {

if (keyCode == KeyEvent.KEYCODE_MENU) {

}

mousePressed();

drawUI();

}

so when I push menu the list should pop up , but it only shows the list for 1 second and then disappeared ! do you know where is the problem ?

You're only displaying the UI when the key is pressed; in other words, only for one frame. Try creating a global boolean variable and toggle it when you press the key. Then, in draw(), call drawUI() only if the boolean is true. Also, you should never call mousePressed()...

thank you calsign, I solved the problem but now when I press list items nothing happens , apparently mousePressed doesn't work !

void onBackPressed() {
}
void keyPressed() {
if (keyCode == KeyEvent.KEYCODE_MENU) {
ret = true;
if (ret = true){
drawUI();
}
}
}

Okay... you're still drawing the UI from within keyPressed(), this is what you want to avoid!
If the problem persists, I don't know enough about Ketai to help you...

Mataarsak,

Make sure to include the callback function in your sketch...add this code:

void onKetaiListSelection(KetaiList klist)

{

  String selection = klist.getSelection();

println("This was picked from the list: " + selection);
}

You can customize the behaviour as you need...if the selection is canceled you will get back an empty string.

good luck,

.j
