关于 delete 键能否运行的问题

Question

我在Enter keyevent上添加setOnKeyListener。但是，在我添加setOnKeyListener 后，delete键还是不能运行，当我删除setOnKeyListener后，delete键就可以运行了。
如何修改这个delete键？

final EditText edittext = (EditText) findViewById(R.id.editText1);
        edittext.setOnKeyListener(new OnKeyListener() {
            @Override
            public boolean onKey(View arg0, int arg1, KeyEvent event) {
                // TODO Auto-generated method stub
                 if (event != null&& (event.getKeyCode() == KeyEvent.KEYCODE_ENTER)) {

                     InputMethodManager in = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                        in.hideSoftInputFromWindow(edittext
                                .getApplicationWindowToken(),
                                InputMethodManager.HIDE_NOT_ALWAYS);

                    applySearch();
                 }
                return true;
            }
        });

Answer 1

edittext.setOnKeyListener(new OnKeyListener() {
            @Override
            public boolean onKey(View arg0, int arg1, KeyEvent event) {
                // TODO Auto-generated method stub
                 if (event != null&& (event.getKeyCode() == KeyEvent.KEYCODE_ENTER)) {

                     InputMethodManager in = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                        in.hideSoftInputFromWindow(edittext
                                .getApplicationWindowToken(),
                                InputMethodManager.HIDE_NOT_ALWAYS);

                    applySearch();
                    return true;
                 }
                return false;
            }
        });

修改成这样应该就没问题了
