We need in lostfindactivity this class, show the Third Setup Wizard page passed the security number, the fourth page if checked, then the anti-theft protection is turned on the picture replaced, the final result such as.

First look at the Last Setup Wizard page:

Package Com.ustc.mobilemanager;import Android.content.intent;import Android.content.sharedpreferences;import Android.content.sharedpreferences.editor;import Android.os.bundle;import Android.view.view;import Android.view.window;import Android.widget.checkbox;import Android.widget.compoundbutton;import Android.widget.compoundbutton.oncheckedchangelistener;public class Setup4activity extends Basesetupactivity { Private sharedpreferences sp;private CheckBox cb_protecting; @Overrideprotected void OnCreate (Bundle Savedinstancestate) {super.oncreate (savedinstancestate); Requestwindowfeature (Window.feature_no_title); Setcontentview (R.LAYOUT.ACTIVITY_SETUP4), SP = getsharedpreferences ("config", mode_private); cb_protecting = ( CheckBox) Findviewbyid (r.id.cb_protecting); Boolean protecting = Sp.getboolean ("Protecting", false); if (protecting) {/ /Mobile phone anti-theft has been turned on Cb_protecting.settext ("mobile phone anti-theft has been turned on"); cb_protecting.setchecked (true);} else {//Mobile phone anti-theft does not turn on Cb_protecting.settext ("mobile phone anti-theft not turned on"); cb_protecting.setchecked (false);} Cb_pRotecting.setoncheckedchangelistener (New Oncheckedchangelistener () {@Overridepublic void oncheckedchanged ( Compoundbutton Buttonview, Boolean isChecked) {if (isChecked) {Cb_protecting.settext ("mobile phone theft is turned on");} else {cb_protecting.settext ("mobile phone anti-theft is not turned on");} Save the selected state Editor editor = Sp.edit (); Editor.putboolean ("Protecting", isChecked); Editor.commit ();});} @Overridepublic void Showback () {Intent Intent = new Intent (this, setup3activity.class); startactivity (Intent); Finish () ;//require finish () or startactivity (intent) aspect to perform overridependingtransition (r.anim.tran_pre_in, r.anim.tran_pre_out);} public void ok (view view) {Editor edit = Sp.edit (); Edit.putboolean ("configed", true); Edit.commit (); Intent Intent = new Int ENT (this, lostfindactivity.class); startactivity (intent); finish ()//Request finish () or startactivity (intent) Aspect behind the execution of Overridependingtransition (r.anim.tran_in, r.anim.tran_out);} @Overridepublic void Shownext () {}}

Sets the font for the response based on the status of the checkbox.

Package Com.ustc.mobilemanager;import Android.app.activity;import Android.content.intent;import Android.content.sharedpreferences;import Android.os.bundle;import Android.view.view;import Android.view.Window; Import Android.widget.imageview;import Android.widget.textview;public class Lostfindactivity extends Activity { Private sharedpreferences sp;private ImageView iv_protecting;private TextView tv_safenumber; @Overrideprotected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); Requestwindowfeature (Window.feature_no_ SP = getsharedpreferences ("config", mode_private);//Determine if you have done the Setup Wizard, if not done, jump to the Settings Wizard page to set, or stay on the current page Boolean configed = Sp.getboolean ("configed", false); if (configed) {//on the phone anti-theft page Setcontentview (r.layout.activity_lost_find); TV _safenumber = (TextView) Findviewbyid (r.id.tv_safenumber); iv_protecting = (ImageView) Findviewbyid (r.id.iv_ protecting);//Set security Number string safenumber = sp.getstring ("Safenumber", "" "), if (safenumber! = null) {Tv_safenumber.settext (Safenumber);} Set the status of the anti-theft protection Boolean protecting = Sp.getboolean ("Protecting", false), if (protecting) {Iv_protecting.setimageresource ( r.drawable.strongbox_app_lock_ic_locked);} else {iv_protecting.setimageresource (r.drawable.strongbox_app_lock_ic_unlock);}} else {//has not done setup wizard Intent intent = new Intent (Lostfindactivity.this,setup1activity.class); startactivity (intent); Finish ()//require finish () or startactivity (intent) aspect to execute overridependingtransition (r.anim.tran_in, r.anim.tran_out);}} public void back (view view) {Intent Intent = new Intent (lostfindactivity.this, Homeactivity.class); StartActivity (Intent Finish ()//require finish () or startactivity (intent) to perform overridependingtransition (r.anim.tran_pre_in, R.anim.tran_ Pre_out);} /** * Re-enter the anti-Theft Settings page (TextView click event) * * @param view */public void Reentersetup (view view) {Intent Intent = new Intent (lostfin Dactivity.this, Setup1activity.class); startactivity (intent); finish ()//Request finish () or startactivity (intent) Aspect behind the execution of Overridependingtransition (r.anim.tran_in, R.anim.tran_out);}}
