Custom adapter and click on item in ListView

Custom adapter and click on item in ListView - android

I have a problem with click on image in item in ListView. When I click I want to show layout which is gone. This is my code:
public class MyActualOffers extends BaseActivity {
private IResponse iResponse = null;
private ListView actualOffersList;
private ActualOffersListAdapter actualOffersAdapter;
private ArrayList<Offers> actualOffersFromJson;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_actual_offers);
actualOffersFromJson = new ArrayList<Offers>();
actualOffersList = (ListView) findViewById(R.id.actualOffersList);
iResponse = new IResponse() {
#Override
public void onResponse(JSONObject jObject) {
// messageUser = new User();
// messageUser.parseJsonResponse(jObject);
// usersMessages.add(messageUser);
// new DownloadImageTask(profileP)
// .execute("http://"+messageUser.getAvatarURL());
//
// messagesListView.refreshDrawableState();
// adapter.notifyDataSetChanged();
// adapter.notifyDataSetInvalidated();
}
#Override
public void onResponse(JSONArray jArray) {
try {
for (int i = 0; i < 3; i++) {
JSONObject messageJSON = (JSONObject)jArray.get(i);
Offers offer = new Offers();
offer.parseJsonResponse(messageJSON);
actualOffersFromJson.add(offer);
}
}catch (JSONException e) {
e.printStackTrace();
}
actualOffersAdapter = new ActualOffersListAdapter(getApplicationContext(), actualOffersFromJson);
actualOffersList.setAdapter(actualOffersAdapter);
// adapter = new MessagesListAdapter(getApplicationContext(), myMessagesList, usersMessages);
// messagesListView.setAdapter(adapter);
}
#Override
public void onError(JSONObject jObject) {
ErrorObject error = new ErrorObject();
error.parseJsonResponse(jObject);
error.showErrorDialog(MyActualOffers.this);
}
};
getActualMyOffers();
}
private void getActualMyOffers(){

}
No when I click on holder.expandIcon in first item, expand layout show in last item of list. How can I create list with my item and properly working click on image in every item?

You are expanding the last item in the list because that was the last view retrieved by getView. The way the code is written now, there is only one isExpand value.
So you need to (a) add isExpand on the ViewHolder, and (b) use the ViewHolder attached to the View that was passed in the event handler. Like this:
holder.expandIcon.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ViewHolder vh = (ViewHolder)v.getTag();
if(vh.isExpand){
vh.actualOffersExpandLayout.setVisibility(View.INVISIBLE);
vh.isExpand = false;
}else{
vh.actualOffersExpandLayout.setVisibility(View.VISIBLE);
vh.isExpand = true;
}
}
});

mproduct.remove(position) or notifyDataSetChange() does not work inside getView method

I have checked most of the places but i could not get the precise answer for this question.
problem in function : getView
What is the problem : When if condition gets true,
mproduct.remove((position));
notifyDataSetChanged();
both statement suppose to work.

If i write Log.e(); It displays promt message.

Problem
First item in the list maps to 5th item. 2nd item to sixth item. I mean if I change radio button at the first item, Same radio button gets selected at the 5th list item also.
Any suggestions?
Is it because of recycling?
How do I resolve it?
I tried saving in Question object and retrieving it. I used pos to retrieve and set. But same problem still exist.

}
When i am bottom of the page and click on item it expands, but exapnded child item doesn't shows to user because it is bottom in the screen.
I want to move that item up in the screen and show expanded items to user.
How can i do that?

You can simply use the method setSelectedGroup()
expandableListView.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
#Override
public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) {
expandableListView.setSelectedGroup(groupPosition);
return true;
}
});
This will move the selected group to the top
EDIT
Finally I came out with a solution for your ExpandableRecyclerAdapter also. Simply put this method inside your adapter implementation. Also you will require the reference of the recyclerView inside the adapter which you can pass to the adapter at the time of initialization.
int lastPos = -1;
#Override
public void onParentListItemExpanded(int position) {
List<? extends ParentListItem> parentItemList = this.getParentItemList();
collapseAllParents();
int finalPos = position;
if (lastPos != -1 && lastPos < position) {
finalPos = position - parentItemList.get(lastPos).getChildItemList().size();
}
expandParent(finalPos);
mRecyclerView.smoothScrollToPosition(finalPos);
lastPos = position;
}
I found this issue at https://github.com/bignerdranch/expandable-recycler-view/issues/156 . Although the solution given there didn't work. Slight tweaking to that make it work.

Use this following code in your expandable listview click listener. Do something liket his
yourExpandableListView.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
#TargetApi(Build.VERSION_CODES.LOLLIPOP)
#Override
public boolean onGroupClick(final ExpandableListView parent, View v, final int groupPosition, long id) {
....
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
parent.smoothScrollToPositionFromTop(groupPosition + 1, 0);
}
},100);
....
return true;
}
});

Use AnimatedExpandableListView

onclick button is not working in listview

My project contains listView(homelistView) that contains button(btnList).
When I click on button(btnList) it must go to another Activity. I tried a lot but I didn't find a good example.
Please suggest me a good example regarding this.
Below is my code:
Here is my listview contains button. When on click of button it must go to other activity
--------------------------------A--
text text button(btnList) B
--------------------------------C---
text text BUTTON(btnList) D
--------------------------------E--
homempleb.xml
Before i used this code in xml. buttonlist worked fine for me as per below code
<ListView
android:id="#+id/homelistView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1.04"
android:dividerHeight="0dip" >
</ListView>
EfficientAdapter.java
public EfficientAdapter(Context context) {
mInflater = LayoutInflater.from(context);
this.context=context;
}
In your ViewHolder class you need to add `Button btnList.`
holder.btnList.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent next=new Intent(context, SeviceDetails.class);
context.startActivity(next);
}
});

Currently i added scroll index to my listview and changed the code as per below.. Listbutton is not working for me now.. Plz help me u can see code for quick reference in EfficientAdapter.JAVA-----> getview method--->holder.btnList.

The problem is in onInterceptTouchEvent method. You are using IndexableListView from woozzu, and this class overrides onInterceptTouchEvent to return true. This means that IndexableListView always steal touch events from your child's views so it can provide it to IndexScroller. You can change this behavior if instead of returning true you enter this condition:
#Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
if (mScroller != null && mScroller.contains(ev.getX(), ev.getY()))
return true;
return super.onInterceptTouchEvent(ev);
}
This way only events meant to interact with IndexScroller will be consumed. Other events will be propagated to children's views, and your button will be clickable.

In your Efficient adapter class declare ViewHolder holder outside getView method
and do as MoshErsan said.
Also Change your
convertView = mInflater.inflate(R.layout.homemplebrowview, null);
to
convertView = mInflater.inflate(R.layout.homemplebrowview, parent,false);

in your adapter, just move
holder.btnList.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(context, "STAT", Toast.LENGTH_SHORT).show();
Intent next = new Intent(context, Home.class);
Log.i("next23", "next");
context.startActivity(next);
}
});
just before return convertView;
you need to set the listener every time the adapter returns a view.

}
}

First remove btnList, btnScan from your MainActivity class.
In your EfficientAdapter class add object Context Context
Change your contructor:
public EfficientAdapter(Context context) {
mInflater = LayoutInflater.from(context);
}
to:
public EfficientAdapter(Context context) {
mInflater = LayoutInflater.from(context);
this.context=context;
}
In your ViewHolder class you need to add Button btnList.
Then in getview method find its view using holder.btnList
Then use:
holder.btnList.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent next=new Intent(context, SeviceDetails.class);
context.startActivity(next);
}
});
in your getview method before return convertView.

try this..
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null){
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.list_layout_ip_addtional_users, null);
}
//Handle TextView and display string from your list
TextView listItemText2 = (TextView)view.findViewById(R.id.list_item_string_name);
listItemText2.setText(list.get(position));
ImageButton button8 = (ImageButton) view.findViewById(R.id.ip_additional_user_edit);
button8.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(context, IPAdditionalUsersEdit.class);
context.startActivity(intent);
}
});
return view;
}
