java - How to get locale of string on android? -


i want know locale of input text in edittext! tried keyboard locale wasn't helpful. don't want type english in edittext me! want user know he/she can't type english!

sorry bad english!

here code :

  edtusernamelogin.addtextchangedlistener(new textwatcher() {         @override         public void beforetextchanged(charsequence charsequence, int i, int i1, int i2) {         }          @override         public void ontextchanged(charsequence charsequence, int i, int i1, int i2) {         }          @override         public void aftertextchanged(editable editable) {             if (editable.tostring().isempty()) {                 mtfusernamelogin.setlabelcolor(g.resources.getcolor(r.color.cpb_white), "نام کاربری");             } else {                 string locale = g.inputmethodmanager.getcurrentinputmethodsubtype().getlocale();                 if (locale.equals("fa") || locale.equals("ar")) {                     mtfusernamelogin.setlabelcolor(g.resources.getcolor(r.color.spink), "نام کاربری باید انگلیسی باشد !");                 } else {                     mtfusernamelogin.setlabelcolor(g.resources.getcolor(r.color.sgreen), "نام کاربری");                 }             }         }     });

the solution :

inputfilter usernamefilter = new inputfilter() {         @override         public charsequence filter(charsequence source, int start, int end, spanned dest, int dstart, int dend) {             string blockcharacterset = " اآبپتثجچحخدذرزژسشصضطظعغفقکگلمنوهی";             if (blockcharacterset.contains(source)) {                 edtnameedit.sethinttextcolor(getresources().getcolor(r.color.grey));                 edtnameedit.sethint("نام و نام خانوادگی");                 return source.tostring();             } else {                 edtnameedit.sethinttextcolor(getresources().getcolor(r.color.spink));                 edtnameedit.sethint("نام و نام خانوادگی باید فارسی باشد!");                 return "";             }         }     };     edtnameedit.setfilters(new inputfilter[]{usernamefilter});

and important line :

    edtnameedit.setinputtype(inputtype.type_text_flag_no_suggestions);

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
