Fragment バックキーリスナー

////////////////////backkey listenner
view.setOnKeyListener(new View.OnKeyListener() {
@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK && event.getAction() == KeyEvent.ACTION_DOWN)
listener.onFinush();
Log.w(TAG,"on pressed back key");
return false;
}

});

view.setFocusableInTouchMode(true);
view.requestFocus();

view.requestFocus();でフォーカスを当てないとだめ！
