很简单，按照以下教程进行操作：
http://labs.makemachine.net/2010/03/android-multi-selection-dialogs/
简而言之：
new AlertDialog.Builder( this )
.setTitle( "Planets" )
.setMultiChoiceItems( new String[]{"Mars", "Earth"}, new boolean[]{false, false}, new DialogSelectionClickHandler() )
.setPositiveButton( "OK", new DialogButtonClickHandler() )
.create();
