Wie darauf reagieren ob das Tastaturfeld geöffnet/geschlossen wurde?

1final View activityRootView = findViewById(R.id.intr_enterAgendId_layout);
2 activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
3 @Override
4 public void onGlobalLayout() {
5
6 int heightDiff = activityRootView.getHeight() - activityRootView.getHeight(); //liefert immer 0. Daher arbeite ich damit nicht.
7 Log.i("CSI","change "+heightDiff);
8 if (keyboard&&getResources().getConfiguration().keyboardHidden== Configuration.KEYBOARDHIDDEN_YES) {
9 Log.i("CSI","keyboardlayout");
10 setContentView(R.layout.intr_enteragentid);
11 keyboard = false;
12 } else if(keyboard==false&&getResources().getConfiguration().keyboardHidden== Configuration.KEYBOARDHIDDEN_NO) {
13 setContentView(R.layout.intr_enteragentid_keyboard);
14 keyboard = true;
15 Log.i("CSI","normales layout");
16 }
