jni - numeric soft keyboard in android using ndk -

i have java code displays numeric soft keyboard in android:

public class mainactivity extends activity {     edittext ed1;      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);         ed1 = (edittext) findviewbyid(r.id.edittext1);         ed1.setinputtype(inputtype.type_class_number);     } } 

my activity_main.xml file:

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingbottom="@dimen/activity_vertical_margin" android:paddingleft="@dimen/activity_horizontal_margin" android:paddingright="@dimen/activity_horizontal_margin" android:paddingtop="@dimen/activity_vertical_margin" tools:context="numberkeypad.inputmethod.mainactivity" >  <edittext     android:id="@+id/edittext1"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_centerhorizontal="true"     android:layout_centervertical="true"     android:ems="10" > </edittext> 

the output is: numeric soft keyboard

i want display same keyboard using ndk jni call , no edittext. have implemented default keyboard in way using following link:

how show soft keyboard on native activity

but facing lot of trouble using same methodology numeric keyboard. great..thanks!

could not find way directly, had override oncreateinputconnection method of view class, , make jni call function using overridden method.

public class numbersview extends view {     public numbersview(context context) {         super(context);     }      @override     public inputconnection oncreateinputconnection(editorinfo outattrs) {         inputconnection inputconnection =  super.oncreateinputconnection(outattrs);         switch(systemkeyboardtype){             case inputtype.type_class_phone:                 outattrs.inputtype |= inputtype.type_class_phone;                 break;             case inputtype.type_class_text:                 outattrs.inputtype |= inputtype.type_class_text;                 break;             case inputtype.type_class_number:                 outattrs.inputtype |= inputtype.type_class_number;                 break;             case inputtype.type_class_datetime:                 outattrs.inputtype |= inputtype.type_class_datetime;                 break;             default:                 outattrs.inputtype |= inputtype.type_class_text;                 break;         }          return inputconnection;     } }   **/ @override protected void oncreate(bundle savedinstancestate) {     calculatedevicedpi();     super.oncreate(savedinstancestate);     myview = new numbersview(getapplicationcontext());     addcontentview(myview,new viewgroup.layoutparams(             viewgroup.layoutparams.wrap_content,             viewgroup.layoutparams.wrap_content));     myview.setfocusable(true);     myview.setfocusableintouchmode(true);     //myview.requestfocus();      mcontext = this; }  public void displaysystemkeyboard(string keyboardtype){     if(keyboardtype.equals("text")) {         systemkeyboardtype = inputtype.type_class_text;     }     else if(keyboardtype.equals("phone")) {         systemkeyboardtype = inputtype.type_class_phone;     }     else if(keyboardtype.equals("number")) {         systemkeyboardtype = inputtype.type_class_number;     }     else if(keyboardtype.equals("datetime")) {         systemkeyboardtype = inputtype.type_class_datetime;     }     else {         systemkeyboardtype = inputtype.type_class_datetime;     }       context ctx = getapplicationcontext();      inputmethodmanager mgr = (inputmethodmanager) ctx.getsystemservice(context.input_method_service);      myview.requestfocus();     // trigger if no physical keyboard open     mgr.restartinput(myview);     mgr.showsoftinput(myview, 0); }  public void hidesystemkeyboard(){     context ctx = getapplicationcontext();     view myview = this.getwindow().getdecorview();     inputmethodmanager mgr = (inputmethodmanager) ctx.getsystemservice(context.input_method_service);     mgr.hidesoftinputfromwindow(myview.getwindowtoken(), 0); } 

and made jni call function:

 if(pshow){     jmethodid showsyskeys = ljnienv->getmethodid(lclassdeviceapi,"displaysystemkeyboard","(ljava/lang/string;)v");     if(showsyskeys == null){          logi("displaysystemkeyboard::couldn't void displaysystemkeyboard method");          return;     }      jstring keyboardtype = ljnienv->newstringutf(keyboardtype.c_str());     if(!keyboardtype)     {         logi( "failed alloc param string in java." );         return;     };      ljnienv->callvoidmethod(lobjdeviceapi,showsyskeys, keyboardtype); } else{     jmethodid hidesyskeys = ljnienv->getmethodid(lclassdeviceapi,"hidesystemkeyboard","()v");     if(hidesyskeys == null){          logi("hidesystemkeyboard::couldn't void hidesystemkeyboard method");          return;     }      ljnienv->callvoidmethod(lobjdeviceapi,hidesyskeys); }  ljavavm->detachcurrentthread();
