I have a class that extends a Fragment. I want when press a button from An Activity to opens this Fragment with its layout in dialog in addition to that the fragment opens normally in its place. Is this possible?
This is my Fragment (TipsFragment.java)
public class TipsFragment extends Fragment{
ListView list;
TipsAdapter tipsAdapter;
AlertDialog PageDialog;
DAO db;
Cursor c;
ArrayList<HashMap<String, String>> tipsList;
HashMap<String, String> map;
ArrayList<HashMap<String, String>> pages;

ImageButton page;
ImageButton add;
ImageButton search;
EditText inputAdd;
EditText inputSearch;

int itemSelected;
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
db = new DAO(activity);
db.open();
}
public TipsFragment(){}
public TipsFragment(int tipType, int itemSelected ){
this.tipType = tipType;
this.itemSelected = itemSelected;
}
#Override
public View onCreateView(final LayoutInflater inflater, final ViewGroup container,
final Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.tips_fragement, container, false);
System.out.println("tipType: "+tipType);
System.out.println("itemSelected: "+itemSelected);
page = (ImageButton) rootView.findViewById(R.id.pager);
add = (ImageButton) rootView.findViewById(R.id.add);
search = (ImageButton) rootView.findViewById(R.id.search);
inputSearch = (EditText) rootView.findViewById(R.id.inputSearch);
inputAdd = (EditText) rootView.findViewById(R.id.inputAdd);
addImage = (ImageView) rootView.findViewById(R.id.imageAdd);
layoutAdd = (RelativeLayout) rootView.findViewById(R.id.layoutAdd);
layoutSearch = (RelativeLayout) rootView.findViewById(R.id.layoutSearch);
if (tipType != 0) {
switch (tipType) {
case 1:
System.out.println("All tips");
if (getActivity().getIntent().getStringExtra("startFrom") == null) {
c = db.getTips("0");
} else {
c = db.getTips(getActivity().getIntent().getStringExtra("startFrom"));
}
break;
case 2:
System.out.println("favorite tips");
c = db.getFavoriteTips();
page.setVisibility(View.GONE);
System.out.println("in favorite, count_records: "+c.getCount());
break;
}
}
System.out.println("count_records: "+c.getCount());
if (c.getCount() != 0) {
if (getActivity().getIntent().getStringExtra("startLabel") != null) {
page = (ImageButton) rootView.findViewById(R.id.pager);
}
tipsList = new ArrayList<HashMap<String, String>>();
list = (ListView) rootView.findViewById(R.id.tipList);
do {
map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(DAO.TIP_ID, c.getString(c.getColumnIndex(c.getColumnName(0))));
map.put(DAO.TIP_CONTENT, c.getString(c.getColumnIndex(c.getColumnName(1))));
// adding HashList to ArrayList
tipsList.add(map);
} while (c.moveToNext());
// Getting adapter by passing xml data ArrayList
tipsAdapter = new TipsAdapter(getActivity(), tipsList);
list.setAdapter(tipsAdapter);
// Click event for single list row
list.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
map = tipsList.get(position);
System.out.println("in list select item, tipType: "+tipType);
if (!MainActivity.tSlidingLayer.isOpened()) {
MainActivity.tSlidingLayer.openLayer(true);
}
}
});
page.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Strings to Show In Dialog with Radio Buttons
}
});
add.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
}
});
search.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {

Since Android supports nesting Fragments (available in the support library) you could show your TipsFragment as a content of another DialogFragment. Avoid this solution whenever possible.
A better solution would be to make TipsFragment extend DialogFragment and that way you can either show the Fragment inline or in a dialog.
1 - Make TipsFragment extends DialogFragment
public class TipsFragment extends DialogFragment {...}
2 - On button click use FragmentTransaction.add or FragmentTransaction.replace to show the DialogFragment inline or include it in your layout and change its visibility.
3 - Show the TipsFragment as a dialog
TipsFragment fr = new TipsFragment();
fr.show(getSupportFragmentManager(), "dialog_fragment_tag");

You need to use the recyclerview to display your list items. Using recyclerview you can get view like -
View view = recyclerview.findViewHolderForAdapterPosition(pos).itemView;
Spinner spinner = view.findViewById(R.id.mySpinner);
This will return you a spinner of whichever position you have passed and afterwards get data from it.
Similarly, you can get view of edittext by using -
EditText edtTxt = view.findViewById(R.id.myEdtTxt);
To see how to get data from database and display that in recyclerview, check the example here - https://github.com/incipientinfo/db-queries

My guess is that at the AdapterView.OnItemClickListener you are using rootView to access the cell properties. Like:
EditText notes = (EditText) rootView.findViewById(R.id.participant_list_item_notes);
...
CheckBox checkBox = (CheckBox) rootView.findViewById(R.id.participant_list_item_checkbox);
You should use the parameter View view from onItemClick like that:
EditText notes = (EditText) view.findViewById(R.id.participant_list_item_notes);
...
CheckBox checkBox = (CheckBox) view.findViewById(R.id.participant_list_item_checkbox);
Let me know if it solves your problem.
Edit:
If the problem is having the item clicked, check https://stackoverflow.com/a/20755698/2174489
I am trying to change the text and check box response of the clicked list item but I am not able to do so. As I not able to get the clicked list item.

Found the answer atlast.
Don't use setOnItemClickListener for item click. Use item view click inside adapter method by using setOnClickListener(). Do things in onClick()
#Override
public View getView(int position, View convertView, ViewGroup parent)
{
View listItemView = convertView;
if (listItemView == null)
{
listItemView = LayoutInflater.from(getContext()).inflate(R.layout.participant_list_item, parent, false);
}
listItemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v)
{
Toast.makeText(mContext, "click item",Toast.LENGTH_LONG).show();
}
});
Participant currentParticipant = getItem(position);
if(currentParticipant.getParticipantGender().equals("F"))
{
TextView idView = (TextView) listItemView.findViewById(R.id.participant_list_item_id);
idView.setTextColor(getColor(mContext, R.color.colorPrimary));
idView.setText(currentParticipant.getParticipantId());
}
else if(currentParticipant.getParticipantGender().equals("M"))
{
TextView idView = (TextView) listItemView.findViewById(R.id.participant_list_item_id);
idView.setTextColor(getColor(mContext, R.color.colorAccent));
idView.setText(currentParticipant.getParticipantId());
}
TextView nameView = (TextView) listItemView.findViewById(R.id.participant_list_item_name);
nameView.setText(currentParticipant.getParticipantName());
final EditText notesView = (EditText) listItemView.findViewById(R.id.participant_list_item_notes);
notesView.setText(currentParticipant.getParticipantNotes());
CheckBox checkedView = (CheckBox) listItemView.findViewById(R.id.participant_list_item_checkbox);
if (currentParticipant.getParticipantCheck().equals("1"))
{
checkedView.setChecked(true);
}
else
{
checkedView.setChecked(false);
}
return listItemView;
}
Remove this from participant_list_item.xml
android:descendantFocusability="blocksDescendants"
Thank you every one for the help.
<CheckBox
android:id="#+id/participant_list_item_checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:focusable="false"
android:clickable="false"
android:layout_marginLeft="16dp"
android:layout_marginStart="16dp" />
Try to replace your CheckBox and add this two line
android:focusable="false"
android:clickable="false"
Try this should work in participant_list_item.xml and remove from listview
android:descendantFocusability="blocksDescendants"
you have to do it like this
private EditText notes;
private CheckBox checkBox;
and put these above onclick
notes = (EditText) rootView.findViewById(R.id.participant_list_item_notes);
String text = notes.getText().toString();
Log.v("Participant Text",text);
checkBox = (CheckBox) rootView.findViewById(R.id.participant_list_item_checkbox);
edittext and check box are the view in the listview
hope this will help you
android:clickable=true
Make sure that you have added clickable property to true.
In participantslist.xml file:
<ListView
android:id="#+id/participant_list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="#color/divider"
android:dividerHeight="1dp"
android:descendantFocusability="beforeDescendants"
android:drawSelectorOnTop="true"
android:headerDividersEnabled="true"
android:clickable=true/>
And let me know if this suggestion was wrong?
I am having a weird issue in my app. In one of my app activity I am inflating three fragments in it with tabs. Everything works fine.
In the fragment in which I am having problem, I have listview which is inflated using adapter and data fro web service. This also works well. Now the problem is this the row which is inflated in adapter, has a hidden view which has visibility=gone in xml. On tap of imageview from that row I make that layout visible through java code. The problem is layout doesn't become visible on tap. I have even set breakpoint on the onClickListener of imageview and it does execute the line which changes the visibility from gone to visible. I am unable to understand what is causing this issue as I am using the same row xml with same data in other screen and there it is working perfectly.
UPDATE
I got to know what's causing this issue but don't know how to solve this. In my activity I am having three fragments. The view that I provided for fragment(in which fragment will be inflated) is causing main problem. I have set height width to match parent but it is not taking match parent height. If the fragment just includes normal views like textview, imageview then also fragment is shown properly.But the problem is if fragment consists of listview, then it only takes height of the custom row that is supplied to the listview. I am able to scroll complete listview in that space.
I don't understand what is causing this behaviour.
My Updated code.

Here are the screenshots of the problem
Comparing both images you can see that the hidden view appears in the space of the single row item and is scroll able completely in that space.
Better upshot were targeted at plus for android developers (Cristophe Beils):
"Your ListView must have its height set to match_parent or a fixed size, not wrap_content.
If you need to add another view fixed at the bottom of the ListView as a footer, you need to put both the ListView and the footer View in a vertical LinearLayout and set layout_height to 0dp and layout_weight to 1 on the ListView so that it takes the remaining vertical space."
Try fillViewPort=true on the list view.. But not sure what why yoi have a scroll view inside a list view.. Could be the issue too.
Try setting match_parent as the height of the listview
I suspect this will force the list view to have a defined height and fix your problem.

It is related to checkbox item in connections.xml which is the list row item. If I remove checkbox, related listeners responses. I think, it may be thought there is no need a setItemOnClickListener(..) method since each row has a checkbox. Or it is a bug.
