Nice Logic With Answer Java Coding ;)
First before we proceed,Its lengthy and if you can't have time and no love for programming then you wont get it so its better to leave it,if you have dedication to eagerness to learn and code you will love it
Today i added one more option due to user demand in Uret Patcher "Show Apps without permissions"
before had only one option "Show system apps"
when i open the activity i do this
check if show_system_apps is checked by user last time which is saved in settings in xml file
if checked then turn switch on else turn switch off (default value is always off when start activity)
Function which check EVENT if SWITCH changed from off to on or on to off is onCheckedChanged()
//then save value to xml to true and
//save value to xml to false
Load installed_apps_now_function()
// but default value is off when start activity so onCheckedChanged function is not executed which check if value is changed on switch
so what i do is i Load the apps when it's value is off by default and load the apps again when value changed next time when user is in Activity
here is code sample below // read comments to understand
boolean b = sp.getBoolean("show_system_apps" ,false);// get value user last save else get false if(b){ sw0.setChecked(true); // onCheckedChange will execute now }else{ sw0.setChecked(false); // onCheckedChange will NOT EXECUTE because default is false already // load apps list (as oncheckchange is not executed) new LoadApps(this).execute(); }
@Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { switch (buttonView.getId()) { case R.id.switchsap: if (sw0.isChecked()) { compul("show_system_apps", true); } else { compul("show_system_apps", false); } // load apps list (any change load list again because user is in activity now) new LoadApps(this).execute(); break;
now as you know i loaded the list when user didnot saved value in case of false or user saved value to false from true last time because onCheckedChanged event is not called as default value is false
but when value is changed from true to false and then false to true so on next time i load the app list
pretty cool right ? everything works fine
now here comes the tricky part added another option to "Show All Apps without permission" now issue comes, it also have switch
now if you add above sample code for another switch the list will be loaded two times,do you want to load list two times ?
HOW WILL YOU SOLVE THIS ?
lets see for another switch
boolean baap = sp.getBoolean("show_apps_without_permissions" ,false); // get value user last save else get false if(baap){ sw01.setChecked(true); }else{ sw01.setChecked(false); }
you can do is either leave this like this so list dont get loaded again because apps are already loaded by above switch
@Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { switch (buttonView.getId()) { case R.id.switchaap: if (sw0.isChecked()) { compul("show_apps_without_permissions", true); } else { compul("show_apps_without_permissions", false); } // dont load apps list as it is loaded by first switch already weather its off or on break;
its cool when you dont load list but guess what ?
if user is in Activity and he changes second switch value either from false to true or true to false means check it or uncheck it ?
list wont be refreshed ,apps list will have same old data ?AHHHHHHHHHHH any idea how to solve it?
here is small working solution how i fixed it
// create a small int field which is 0 when activity start
private int dontloadagain = 0;
boolean bsap = sp.getBoolean("Show_system_apps" ,false); if(bsap){ sw0.setChecked(true); }else{ sw0.setChecked(false); // load apps list (When switch doesot change load list) new LoadApps(this).execute(); } boolean baap = sp.getBoolean("show_apps_without_permissions" ,false); if(baap){ sw01.setChecked(true); }else{ sw01.setChecked(false); dontloadagain = dontloadagain+1; // change field to 1 }
as you can see the picture above no matter if switch value is off or on ,the apps list always get loaded on activity start what we have to fix it when user click next time on switch it should work fine
@Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { switch (buttonView.getId()) { case R.id.switchsap: if (sw0.isChecked()) { compul("show_system_apps", true); } else { compul("show_system_apps", false); } // load apps list (any change load list again) new LoadApps(this).execute(); break; case R.id.switchaap: if (sw01.isChecked()) { compul("show_apps_without_permissions", true); } else { compul("show_apps_without_permissions", false); } if(dontloadagain != 0) { // MAGIC 1 // load apps list (any change load list again) new LoadApps(this).execute(); } dontloadagain = dontloadagain+1; // MAGIC 2 break;
see it worked fine with all 4 outcomes
what i did now as you know list will be updated on start of activity by using first switch case
now when using second switch
IF USER HAS SAVED the value to TRUE ? // onCHECKCHANGED WILL BE CALLED
means the list wont be updated second time again as dontloadagain = 0 which needs to be not equal to 0 to load
now what we do is we increment it again cus now when user click it loads the list
IF USER HAS SAVED THE VALUE TO FALSE ? OR Not saved by default it is false // onCHECKCHANGED WILL NOT BE CALLED
dontloadagain = 1 we increment it because when next time user click switch 2 only it loads the list
next time it will be dontloadagain = 2 ,3,4,5,6 etc so list will get loaded every time user click switch 2
Hope you get what i want to convey,if you didnot its cool
