Cordova Ionic Keyboard插件在“Init”上完全禁用

Question

I have the following problem, I need to disable the native Keyboard completely. The keyboard should only show when I call the show() and hide when I call the close() function (this will be on a Button for the user to toggle the Keyboard). The Keyboard showing on clicking the Field and on Focus needs to be completely disabled.

On Stackoverflow I found this: InputMethodManager im = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE); im.hideSoftInputFromWindow(editText.getWindowToken(), 0);

So my thought was In the "Init"(Line 52 in the IonicKeyboard.java) I need to change it.

if ("init".equals(action)) {
            cordova.getThreadPool().execute(new Runnable() {
                public void run() {

                  //new Logic on init
                  View v = cordova.getActivity().getCurrentFocus();
            ((InputMethodManager) cordova.getActivity().getSystemService(Context.INPUT_METHOD_SERVICE)).hideSoftInputFromWindow(v.getWindowToken(), 0);

              DisplayMetrics dm = new DisplayMetrics();
                cordova.getActivity().getWindowManager().getDefaultDisplay().getMetrics(dm);
                final float density = dm.density;

                //http://stackoverflow.com/a/4737265/1091751 detect if keyboard is showing
                final View rootView = cordova.getActivity().getWindow().getDecorView().findViewById(android.R.id.content).getRootView();
                OnGlobalLayoutListener list = new OnGlobalLayoutListener() {
                    int previousHeightDiff = 0;
                    @Override
                    public void onGlobalLayout() {
                        Rect r = new Rect();
                        //r will be populated with the coordinates of your view that area still visible.
                        rootView.getWindowVisibleDisplayFrame(r);

                        PluginResult result;

                        int heightDiff = rootView.getRootView().getHeight() - r.bottom;
                        int pixelHeightDiff = (int)(heightDiff / density);
                        if (pixelHeightDiff > 100 && pixelHeightDiff != previousHeightDiff) { // if more than 100 pixels, its probably a keyboard...
                            String msg = "S" + Integer.toString(pixelHeightDiff);
                            result = new PluginResult(PluginResult.Status.OK, msg);
                            result.setKeepCallback(true);
                            callbackContext.sendPluginResult(result);
                        }
                        else if ( pixelHeightDiff != previousHeightDiff && ( previousHeightDiff - pixelHeightDiff ) > 100 ){
                            String msg = "H";
                            result = new PluginResult(PluginResult.Status.OK, msg);
                            result.setKeepCallback(true);
                            callbackContext.sendPluginResult(result);
                        }
                        previousHeightDiff = pixelHeightDiff;
                     }
                };

                rootView.getViewTreeObserver().addOnGlobalLayoutListener(list);


                PluginResult dataResult = new PluginResult(PluginResult.Status.OK);
                dataResult.setKeepCallback(true);
                callbackContext.sendPluginResult(dataResult);
            }
        });
        return true;
    }
    return false;  // Returning false results in a "MethodNotFound" error.
}

Sadly this does not work at all...

I think I have to change the close / show function too but I am not really sure what the correct code is, and I dont know if this change would affect other Keyboard behaviour. (But I basically need Focus without Keyboard)

I also found this Cordova Plugin

which looks very promising, but I decided to change this in the Ionic Keyboard Plugin, because I need the same behaviour in Windows too. Very glad if someone could help me out here.

This can be accomplished by disabling all inputs with ng-disabled and later showing the keyboard with the Ionic Keyboard Plugin .

If you do not want the inputs to appear differently when disabled, you can override this style with CSS using the :disabled selector.

Hide on load:

<input ng-disabled="hideKeyboard">

hideKeyboard = true;

Show on function:

<input ng-disabled="hideKeyboard">

function showKeyboard(){
  hideKeyboard = false;
  cordova.plugins.Keyboard.show();
}
