Updating the parent snippet to PopupWindow.dismiss
I have a popupWindow that modifies a SQLight table that loads a spinner in the parent window. I would like the spinner on the parent window to update with new values when I dismiss the PopupWindow. The code below shows my progress creating a listener that would detect PopupWindow firing. The listener I am still not working. I think I am missing something in structuring the listener. I have included the ShowPopup class as well as the (Tab3Fragment) fragment that is the parent of this window.
showPopup.java
public class showPopup extends PopupWindow{
Context m_context;
Button btnDismiss;
PopupWindow popup;
Tab3Fragment Tab3Fragment;
OnDismissListener listener;
public showPopup(Context context){
super(context);
m_context = context;//was commented out
setContentView(LayoutInflater.from(context).inflate(R.layout.popup_layout, null));
setHeight(LayoutParams.WRAP_CONTENT);
setWidth(LayoutParams.WRAP_CONTENT);
}
public void init(View v){
LayoutInflater inflater = (LayoutInflater)m_context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View popUpView = inflater.inflate(R.layout.popup_layout, null, false);
final PopupWindow popup = new PopupWindow(popUpView, 600, 400, true);
popup.setContentView(popUpView);
popup.showAtLocation(v, Gravity.CENTER_HORIZONTAL, 0, 0);
btnDismiss = (Button) popUpView.findViewById(R.id.btndismissxml);
btnDismiss.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View anchor) {
popup.dismiss();
}
});
}
@Override
public void setOnDismissListener(OnDismissListener listener){
this.listener = listener;
}
}
Tab3Fragment.java
public class Tab3Fragment extends Fragment implements OnClickListener{
Context context;
Button btnPopup, btnSpinnerRefresh;
Spinner spinnerSpecies;
public static int iSpeciesPosition;
showPopup showPopup;
ArrayAdapter<String> arrayAdapterSpecies;
OnDismissListener dismissListener;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup containerGroup, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.tab3_fragment, containerGroup, false);
btnPopup = (Button)v.findViewById(R.id.btnPopupxml);
btnPopup.setOnClickListener(this);
btnSpinnerRefresh = (Button)v.findViewById(R.id.btnSpinnerRefreshxml);
btnSpinnerRefresh.setOnClickListener(this);
spinnerSpecies = (Spinner) v.findViewById(R.id.spinnerSpeciesxml);
spinnerSpecies.setAdapter(arrayAdapterSpecies);
if(savedInstanceState != null){
iSpeciesPosition = savedInstanceState.getInt("speciesPosition_key");
populateTab3Fragment(v);
}else if(savedInstanceState == null){
populateTab3Fragment(v);
}
return v;
}
//@Override
public void onViewCreated(View v) {
populateTab3Fragment(v);
/******************************************************************************************************
Can setOnDismissListener be used outside of showPopup class to indicate that showPopup has dismissed?
******************************************************************************************************/
showPopup popup = new showPopup(context);
popup.setOnDismissListener(new OnDismissListener(){
@Override
public void onDismiss(){
Toast.makeText(getActivity().getApplicationContext(), "onDismiss() works.", Toast.LENGTH_LONG).show();
loadSpinnerData();
}
});
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btnPopupxml:
new showPopup(getActivity().getApplicationContext()).init(v);
break;
case R.id.btnSpinnerRefreshxml:
loadSpinnerData();//temporary workaround to refresh spinner...
break;
}
}
/**
* Function to load the spinner data from SQLite database
* */
public void loadSpinnerData() {
//omitted
}
public void populateTab3Fragment(View v){
loadSpinnerData();
}
}

It never got to the point where I could update the parent window directly on the child PopupWindow. The final solution (workaround) was to use the replacemanager replace () function after the onTouch event from the spinner only when the static flag (iSpeciesRefresh) was set, which specified the modified lookup table spinner.
public class dataCapture extends Fragment implements OnClickListener {
String szSpecies;
static public int iSpeciesRefresh = 1;
Spinner spinnerSpecies;
...
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.data_capture, container, false);
...
spinnerSpecies = (Spinner) v.findViewById(R.id.spinnerSpeciesxml);
spinnerSpecies.setOnTouchListener(new View.OnTouchListener() {//refreshes fragment as needed...
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
if (iSpeciesRefresh == 1) {//this is application default
//do nothing
} else if (iSpeciesRefresh == 0) {//value is reset to "0" at SAVE, UPDATE, or DELETE in speciesPopupWindow.
refreshDataCapture();
iSpeciesRefresh = 1;
}
return false;
}
});
...
}
public void refreshDataCapture() {
Fragment currentFragment = (dataCapture) getFragmentManager().findFragmentByTag("data_capture");
if (currentFragment == null) {
currentFragment = new dataCapture();
} else if (currentFragment != null) {
getFragmentManager().popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE);
getFragmentManager().beginTransaction().replace(R.id.fragment_placeholder, new dataCapture(), "data_capture").addToBackStack(null).commit();
}
}

In your methods onCreateView
and onViewCreated
you do btnPopup.setOnClickListener(this);
, but then in the show method init()
of the showPopup class, you overwrite your snippet as a listener and assign a new anonymous listener instead. I assume you need to rework how you assign the listener and make sure you don't overwrite it like that.
PS For the sake of maintainability (and the sanity of other developers looking at your code), it's a convention to name classes with a camel-top, and they shouldn't contain verbs. Something like MyCustomPopup
it would be better.
