what I am trying to do, is implement a dropdown inside a pop up menu. but when I click on the dropdown, I get this error
android.view.WindowManager$BadTokenException: Unable to add window -- token android.view.ViewRootImpl$W@c1d0e4f is not valid; is your activity running?
The pop up is call after the click of a button. This is how:
btnCustomer.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(LAYOUT_INFLATER_SERVICE);
View customView = inflater.inflate(R.layout.popup_customer,null);
mPopupWindow = new PopupWindow(
customView,
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT,
true
);
if(Build.VERSION.SDK_INT>=21){
mPopupWindow.setElevation(5.0f);
}
ImageButton closeButton = (ImageButton) customView.findViewById(R.id.ib_close);
spnDocumentType1 = customView.findViewById(R.id.spnCustomerDocumentType1);
DocumentType documentType = new DocumentType();
documentsTypeList = documentType.getDocumentTypes();
String[] documentTypesDescription = new String[documentsTypeList.size()];
for (int i = 0 ; i < documentsTypeList.size() ; i++) {
documentTypesDescription[i] = documentsTypeList.get(i).nameDocumentType;
}
ArrayAdapter<CharSequence> documentsTypeAdapter = new ArrayAdapter<CharSequence>(context,
R.layout.support_simple_spinner_dropdown_item, documentTypesDescription);
spnDocumentType1.setAdapter(documentsTypeAdapter);
//buildDocumentTypesAdapter(context);
closeButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
mPopupWindow.dismiss();
}
});
mPopupWindow.showAtLocation(mRelativeLayout, Gravity.CENTER,0,0);
}
});
Any help would be great thanks!
