From: http://blog.csdn.net/xys289187120/article/details/6601613

Lertdialog. builder = new alertdialog. builder (maindialog. this); msinglechoiceid =-1; builder. seticon (R. drawable. icon); builder. settitle ("single choice"); builder. setsinglechoiceitems (mitems, 0, new dialoginterface. onclicklistener () {public void onclick (dialoginterface Diener, int whichbutton) {msinglechoiceid = whichbutton; showdialog ("the id you selected is" + whichbutton + ", "+ mitems [whichbutton]) ;}}); builder. setpositivebutton ("OK", new dialoginterface. onclicklistener () {public void onclick (dialoginterface Diener, int whichbutton) {If (msinglechoiceid> 0) {showdialog ("You selected" + msinglechoiceid) ;}}); builder. setnegativebutton ("cancel", new dialoginterface. onclicklistener () {public void onclick (dialoginterface dialog, int whichbutton) {}}); builder. create (). show ();

2. Multi-choice list box

From: http://blog.csdn.net/xys289187120/article/details/6601613

Alertdialog. builder = new alertdialog. builder (maindialog. this); multichoiceid. clear (); builder. seticon (R. drawable. icon); builder. settitle ("Multiple Choices"); builder. setmultichoiceitems (mitems, new Boolean [] {false, false}, new dialoginterface. onmultichoiceclicklistener () {public void onclick (dialoginterface dialog, int whichbutton, Boolean ischecked) {If (ischecked) {multichoiceid. add (whichbutton); showdialog ("the id you selected is" + whichbutton + "," + mitems [whichbutton]);} else {multichoiceid. remove (whichbutton) ;}}); builder. setpositivebutton ("OK", new dialoginterface. onclicklistener () {public void onclick (dialoginterface Diener, int whichbutton) {string STR = ""; int size = multichoiceid. size (); For (INT I = 0; I <size; I ++) {STR + = mitems [multichoiceid. get (I)] + "," ;}showdialog ("You selected" + Str) ;}}); builder. setnegativebutton ("cancel", new dialoginterface. onclicklistener () {public void onclick (dialoginterface dialog, int whichbutton) {}}); builder. create (). show ();
