android - How to show specific properties in the settings -

-

in android application have setting layout 4 properties. can call settings mainactivity , noticeactivity. have overwritten method: 

 @override  public boolean onoptionsitemselected(menuitem item) {     switch (item.getitemid()) {          case r.id.action_settings:             intent intent = new intent(this, settingsactivity.class);             startactivity(intent);             return true;     }  }

to show settings have these 2 classes:

public class settingsactivity extends preferenceactivity implements sharedpreferences.onsharedpreferencechangelistener {    @override    protected void oncreate(bundle savedinstancestate) {        super.oncreate(savedinstancestate);         getfragmentmanager().begintransaction()             .replace(android.r.id.content, new settingsfragment())             .commit();    } }  public class settingsfragment extends preferencefragment {    @override    public void oncreate(bundle savedinstancestate) {        super.oncreate(savedinstancestate);         // preference_general -> layout 4 properties        addpreferencesfromresource(r.xml.preference_general);    } }

what want is: if settings called mainactivity, want show 4 properties, if called noticeactivity want show first three.

how can without creating second layout?

you can defining constant in intent in both activity.for example:

intent intent = new intent(this, settingsactivity.class); intent.putextra("activity","first_activity"); startactivity(intent);

remember, name "activity" should same in both activities. , use checking calling specific settings in setting activity. example:

public class settingsactivity extends preferenceactivity implements sharedpreferences.onsharedpreferencechangelistener { @override protected void oncreate(bundle savedinstancestate) {    super.oncreate(savedinstancestate);     intent = getintent();    string checkingvalue = i.getstringextra("activity");     if(checkingvalue != null){   //or else        //setting layout 4 properties    }else{       //setting layout 3 properties    } } }

hope help!

this follow question undefined reference rsa_generate_key in openssl? have openssl program generate rsa key, follows : #include <stdio.h> #include <openssl/rsa.h> #include <openssl/pem.h> int main(int argc, char* argv[]) { rsa *r = null; int ret; r = rsa_new(); bignum *bne = null; ret = rsa_generate_key_ex(r, 2048, bne, null); return 0; } when compile gcc -i../include rsatest.c -lcrypto -l. i undefined reference errors functions in libraries gdi32 , zlib. so correct this, have add -lz , -lgdi32, as gcc -i../include/ rsatest.c -lcrypto -lz -lgdi32 -l. my question is, aren't static libcrypto , libssl self sufficient? in why having add libraries make work? there option should have added while compiling library prevent this? i'm using 64 bit windows mingw compiler. made openssl library of msys , make.

when draw attributed string fixed line height text kit, characters aligned bottom of line fragment. while make sense on 1 line characters varying in size, breaks flow of text multiple lines. baselines appear decided largest descender each line. i've found article people behind sketch explaining exact problem in bit more detail , showing solution does, not explaining how achieved this. this want basically: when showing 2 lines large line height, result far ideal: the code i'm using: let smallfont = uifont.systemfont(ofsize: 15) let bigfont = uifont.systemfont(ofsize: 25) let paragraphstyle = nsmutableparagraphstyle() paragraphstyle.minimumlineheight = 22 paragraphstyle.maximumlineheight = 22 var attributes = [ nsfontattributename: smallfont, nsparagraphstyleattributename: paragraphstyle ] let textstorage = nstextstorage() let textcontainer = nstextcontainer(size: cgsize(width: 250, height: 500)) let layoutmanager = nslayoutmanager() textstorage.append(n...
