Call android keyboard doesn't work

Raz

hi, I've tried to run keyboard on android and I get an error. the error is: the function getSystemService does not exist. here is the code.

import android.view.inputmethod.InputMethodManager;
import android.content.Context;
boolean showing=false;

void setup() {
  fullScreen();
}

void draw() {
  if (showing)
    showVirtualKeyboard();
  else
    hideVirtualKeyboard();
}

void mousePressed() {
  showing=true;
}

void showVirtualKeyboard() {
  InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
  imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
}

void hideVirtualKeyboard() {
  InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
  imm.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0);
}

anybody knows why?

I would suggest using the ketai library. You can do exactly those calls and the library will handle everything to show/hide your keyboard:

ketai.org/reference/ui/ketaikeyboard/

An example using the library is found here:

http://ketai.org/examples/ui/

You need to install the library. In processing, go to menu sketch >> import library... >> Add library... and then search for ketai and install it.

I hope this helps,

Not time enough to test your code which seems good except that you are not in an activity but in a fragment: getSystemService comes from Context which is extended by an Activity, not in a fragment; so you have to change your code adding reference to the main activity which has created the fragment...

Try that::

InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);

@akenaton not working for me. now it shows "the function getActivity() does not exist".

Check this example: editText, akenaton's post.

Are you trying getActivity or this.getActivity() ?

Notice that example also activates the keyboard. I hope this helps,

@raz=== yes, i know that it complains about getActivity() yet it works ( of course if you have imported:: import android.app.Activity;

@akenaton I've imported this abd it's still not working

try this:: it works; though there is another problem with your boolean that you have to solve.

        import android.view.inputmethod.InputMethodManager;
        import android.content.Context;
        import android.app.Activity;
        boolean showing = false;
        Activity act;

        void setup() {
          fullScreen();
          act = this.getActivity();
        }

        void draw() {


          if (showing)
            showVirtualKeyboard();
          else
            hideVirtualKeyboard();
        }

        void mousePressed() {
          showing=true;

        }

        void showVirtualKeyboard() {
          InputMethodManager imm = (InputMethodManager) act.getSystemService(Context.INPUT_METHOD_SERVICE);
          imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
        }

        void hideVirtualKeyboard() {
          InputMethodManager imm = (InputMethodManager) act.getSystemService(Context.INPUT_METHOD_SERVICE);
          imm.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0);
        }

try this (which solves your boolean and toggle in draw)

 import android.view.inputmethod.InputMethodManager;
        import android.content.Context;
        import android.app.Activity;
        boolean showing= false;
        Activity act;



        void settings(){
          fullScreen();
        }
        void setup() {

          act = this.getActivity();


        }

        void draw() {


        }

        void mouseReleased() {

          if (!showing){
            showVirtualKeyboard();
          }else{
            hideVirtualKeyboard();
          }


        }

        void showVirtualKeyboard() {
          InputMethodManager imm = (InputMethodManager) act.getSystemService(Context.INPUT_METHOD_SERVICE);
          imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
          showing = true;
        }

        void hideVirtualKeyboard() {
          InputMethodManager imm = (InputMethodManager) act.getSystemService(Context.INPUT_METHOD_SERVICE);

          imm.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0);

          showing = false;

        }
