2. Some important Java code that can be referenced

2.1 Set whether to display Bt_delete_password ImageButton

Private voidShowbtndeletepassword () {Metpassword.setontouchlistener (NewOntouchlistener () {@Override Public BooleanOnTouch (View V, motionevent event) {//TODO auto-generated Method Stub                if(Metpassword.gettext (). toString (). Trim ()! =NULL&&!metpassword.gettext (). toString (). Trim (). Equals ("") {mbtndeletepassword.setvisibility (view.visible);                } mbtndeletepassword.setvisibility (view.invisible); return false;        }        }); Metpassword.addtextchangedlistener (NewTextwatcher () {@Override Public voidBeforetextchanged (Charsequence S,intStartintCount,intAfter ) {                //TODO auto-generated Method Stub} @Override Public voidOnTextChanged (Charsequence S,intStartintbefore,intcount) {                //TODO auto-generated Method Stub                if(!Textutils.isempty (s)) {mbtndeletepassword.setvisibility (view.visible); } Else{mbtndeletepassword.setvisibility (view.invisible); }} @Override Public voidaftertextchanged (Editable s) {//TODO auto-generated Method Stub            }        }); }

2.2 Set whether EditText displays the password as normal text or as a password

2.2.1 Partial initialization of code in OnCreate

Mbtnshowpassword = (ImageButton) Findviewbyid (R.id.bt_show_password);
Mbtnshowpassword.setonclicklistener (this); Mbtnshowpassword.settag (r.drawable.password_hide);

The Click event code for 2.2.2 in Bt_show_password is as follows:

 CaseR.id.bt_show_password:intDrawavleid; Try{Drawavleid=(Integer) Mbtnshowpassword.gettag (); } Catch(Exception e) {//Todo:handle ExceptionE.printstacktrace (); Drawavleid= 0; }            if(Drawavleid = =r.drawable.password_hide)                {Mbtnshowpassword. Setbackgroundresource (R.drawable.password_look);                Mbtnshowpassword.settag (R.drawable.password_look); //text is displayed normallyMetpassword. Setinputtype (Inputtype.type_text_variation_visible_password); Editable etable=Metpassword.gettext ();            Selection.setselection (Etable, Etable.length ()); } Else{Mbtnshowpassword. Setbackgroundresource (R.drawable.password_hide);                Mbtnshowpassword.settag (R.drawable.password_hide); //text is displayed in a password formatMetpassword.setinputtype (Inputtype.type_class_text|Inputtype.type_text_variation_password); //the following two lines of code are implemented: the input box cursor is always behind the input textEditable etable =Metpassword.gettext ();            Selection.setselection (Etable, Etable.length ()); }             Break;
