[android-developers] Re: How to dismiss the AlertDialog without buttons after clicking on any item in the Alert Dialog

[Greg Krimer]

If you don't want buttons then you probably don't want to use
AlertDialog because an AlertDialog has to have at least one button.
Instead, use the Dialog class that AlertDialog extends. A Dialog can
display any view hierarchy you want. You can then attach listeners to
one or more views in your hierarchy that will cancel the dialog. Here
is a really simple example:

// assuming the dialog is constructed within your activity
final Dialog d = new Dialog(this);
d.setTitle("My Dialog");
TextView t = new TextView(this);
t.setText("Click me to dismiss the dialog");
t.setClickable(true);
t.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
d.dismiss();
}
});
d.setContentView(t);
d.show();

Of course, you would want to define your view hierarchy in XML and use
setContentView(int) instead.

Take a look at the documentation for the Dialog class to see what
methods are available. In particular there is a method
setCanceledOnTouchOutside() which I guess is the opposite of what you
want, but is interesting nonetheless.

Hope this helps,

Greg
