[FIXED] How to show a message box before star an activity?

Issue

In my activity i throw a new one with this code:

    intent = new Intent(this, NewActivity.class);
    startActivity(intent);

How to show a message before launching new activity? I would like to show a warning to users before going to new activity, in which just press OK button to go on...

Solution

Simply create a dialog.

Dialog dialog = new AlertDialog.Builder(getActivity())
               .setMessage(R.string.dialog_fire_missiles)
               .setPositiveButton(R.string.fire, new DialogInterface.OnClickListener() {
                   public void onClick(DialogInterface dialog, int id) {
                       Intent intent = new Intent(MainActivity.this, NewActivity.class);
                       startActivity(intent);
                   }
               })
               .setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
                   public void onClick(DialogInterface dialog, int id) {
                       // User cancelled the dialog
                   }
               }).create();

dialog.show();
