Question

What I am trying to do is update a TextView with each key event – basically copying the contents of the EditText to the TextView. For some reason, it’s not working. Here’s the code:

    View.OnKeyListener keyHandler = new OnKeyListener(){

        public boolean onKey(View v, int keyCode, KeyEvent event) {
            TextView id = (TextView)findViewById(R.id.previewEmplIdData);
            TextView fn = (TextView)findViewById(R.id.previewNameData);
            TextView ttl = (TextView)findViewById(R.id.previewTitleData);
            TextView mgr = (TextView)findViewById(R.id.previewMgrData);
            TextView loc = (TextView)findViewById(R.id.previewLocData);
            TextView strt = (TextView)findViewById(R.id.previewStartData);
            String text = "";
            EditText et;
            switch(v.getId()){
            case R.id.etFirstName:
                et = (EditText)v; // must first switch to a text field
                text = et.getText().toString();
                fn.setText(text);
                break;
            case R.id.etLastName:
                et = (EditText)v;
                text = et.getText().toString();
                break;
            case R.id.etEmplId:
                et = (EditText)v;
                text = et.getText().toString();
                id.setText(text);
                break;
            case R.id.etStartDate:
                et = (EditText)v;
                text = et.getText().toString();
                strt.setText(text);
                break;
            case R.id.etTitle:
                et = (EditText)v;
                text = et.getText().toString();
                ttl.setText(text);
                break;
            case R.id.spinnerLocation:
                break;
            case R.id.spinnerManager:
                break;
            }
            return false;
        }
    };

Basically I’m switching through the View id’s on key press, and then casting the view to the EditText. I’m not really sure why this doesn’t work…I’ve always been pretty unlucky with getting switch statements to work. Any help please?

Where do you apply this keyHandler? If you just created and initialized it, but didn’t used in any view, it won’t run at all.
