As shown in the image, I am able to render the view. But the onChildClick event of Expandable view is not getting triggered.
Also the touch event in the adapter is not responding. My layout details are mentioned below.
The full source code for this can be found in here.
main_activity.xml
<ExpandableListView

android:layout_width="match_parent"

</LinearLayout>
**My Solution : **
Touch events are directly passed to the UI Elements of the View holder in the Recycler List view. But to give the touch event to the whole layout I have added the transparent button on top of child_item layout and added a click listener. Following is the updated child_item.xml
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<FrameLayout
android:layout_height="match_parent"
android:layout_width="match_parent" >
<Button
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/dummy_click"
android:background="#android:color/transparent"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:padding="10dp"
android:background="#color/colorGrey"
>
<ImageView
android:id="#+id/img_subcategory"
android:layout_gravity="center"
android:src="#mipmap/ic_launcher"
android:layout_marginTop="10dp"
android:layout_width="180dp"
android:layout_height="90dp"
android:scaleType="fitXY"/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Sub Category"
android:textColor="#color/colorWhite"
android:layout_marginTop="10dp"
android:layout_marginBottom="5dp"
android:gravity="center"
android:id="#+id/txt_subcategory"
android:textSize="#dimen/app_text_title"/>
</LinearLayout>
</FrameLayout>
</LinearLayout>
Theory
ExpandableListView, child click sample:
for click on child, you can handle this way.
getExpandableListView().setOnChildClickListener(new OnChildClickListener() {
public boolean onChildClick(ExpandableListView parent, View v,
int groupPosition, int childPosition, long id) {
// your code...
}
});
Expandable RecyclerView, useful library and easy item click support:
This blog post by Hugo shows an alternative way without listeners:
http://www.littlerobots.nl/blog/Handle-Android-RecyclerView-Clicks/
It comes down to adding these lines:
ItemClickSupport.addTo(mRecyclerView).setOnItemClickListener(new ItemClickSupport.OnItemClickListener() {
#Override
public void onItemClicked(RecyclerView recyclerView, int position, View v) {
// do it
}
});
When using this class:
public class ItemClickSupport {...}
And this value in ids.xml:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<item name="item_click_support" type="id" />
</resources>
Why doesn't RecyclerView have onItemClickListener()? And how RecyclerView is different from Listview?
Since the introduction of ListView, onItemClickListener has been
problematic. The moment you have a click listener for any of the
internal elements the callback would not be triggered, but it wasn't
notified or well documented (if at all) so there was a lot of
confusion and SO questions about it.
OnItemClickListener doesn't work with ListView item containing button
Just add this line into the item views instead of listView itself
android:focusable="false"
Check more detail about this from: Android custom ListView unable to click on items
Practice
#Override
public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {
ChildHolder childHolder = null;
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.item_group_child, parent, false);
childHolder = new ChildHolder();
// Fix listview onclicklistener issue: inner views can not be focusable
childHolder.YOUR_INNER_BUTTON = (YOUR_BUTTON_TYPE) convertView.findViewById(R.id.YOUR_BUTTON_ID);
childHolder.YOUR_INNER_BUTTON.setFocusable(false);
convertView.setTag(childHolder);
}
else {
childHolder = (ChildHolder) convertView.getTag();
}
childHolder.horizontalListView = (RecyclerView) convertView.findViewById(R.id.mobiles);
LinearLayoutManager layoutManager = new LinearLayoutManager(context, LinearLayoutManager.HORIZONTAL, false);
childHolder.horizontalListView.setLayoutManager(layoutManager);
MobileAdapter horizontalListAdapter = new MobileAdapter(context, brands.get(groupPosition).mobiles);
childHolder.horizontalListView.setAdapter(horizontalListAdapter);
return convertView;
}
Added two lines to your code based on my legacy code:
// Creates a ViewHolder and store references to the children views (collapsed)
holder = new ViewHolderChildren();
holder.textLine = (TextView) convertView.findViewById(R.id.usersTextLine);
holder.subtextLine = (TextView) convertView.findViewById(R.id.usersSubtextLine);
holder.iconLine = (ImageView) convertView.findViewById(R.id.usersIconLine);
holder.buttonLine = (ImageButton) convertView.findViewById(R.id.usersButtonLine);
holder.infoLine = (TextView) convertView.findViewById(R.id.usersInfoLine);
holder.infoLine.setVisibility(TextView.GONE);
holder.userprofileButton = (ImageButton) convertView.findViewById(R.id.usersUserprofileBtn);
holder.buttonLine.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// if gone, set visible and arrow up image
if (holder.infoLine.getVisibility() == TextView.GONE) {
holder.infoLine.setVisibility(TextView.VISIBLE);
holder.buttonLine.setImageLevel(1);
}
// if visible, set gone and arrow down image
else {
holder.infoLine.setVisibility(TextView.GONE);
holder.buttonLine.setImageLevel(0);
}
}
});
//fixed listview onclicklistener bug: inner views can not be focusable
holder.buttonLine.setFocusable(false);
convertView.setTag(holder);

I am navigating a simple listView with a remote control, using DPAD_UP to go up & DPAD_DOWN to go down the list. I am not doing anything special beyond the vanilla stuff you see going on below. Each time I click the down button it scrolls to the next row down just fine. However, when going the reverse direction (i.e. clicking the up button) I have to click it twice to scroll up a row except for a select few # of rows which consistently work.
Each time I click the up button the OnItemSelectedListener is fired. For example, I am at position 10, I hit the up button, onItemSelected(pos=10) is fired. I hit the up button again, now the listview scrolls up and onItemSelected(pos=9) is fired. I repeat, no change in listView & onItemSelected(pos=9), etc.
Using Jelly Bean, API Level 17, this is not touchscreen.

I'm beginner in android development and i a have question about Listview and android:onclick attribute.
I try to use attribute android:onclick ="myMethod" on each element of my listview instead of define OnItemClickListener/onItemClick (too much verbose for me)
MyMethod is executed but how can i get clicked element (current context) ?
Thanks in advance
As a beginner, setting an OnItemClickListener might seem a bit scary, but it's really not a big deal at all (and a core concept you should be learning anyway!).
So if you have a simple layout with a ListView in it like this...
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/containerView"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ListView
android:id="#+id/myListview"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
You can set up an OnItemClickListener with just this code:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.your_listview_layout);
listView = (ListView)findViewById(R.id.myListview);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//Every time an item is clicked, you can handle it right here.
}
});
}
So every time an item in your list is clicked, the onItemClick method is fired, and you can figure out which item was clicked by using the int position argument that comes in.
If i am right your question is about implementing on click listener on each listrow item instead of list row.
If that is correct this is how you should implement:
1.In your adapter of getView() method you might be inflating a layout for list row like below:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.list_row_layout, parent, false);
return convertView;
}
In the above code list_row_layout is the xml file i'm inflating.
Go to that layout and add the following line android:descendantFocusability="blocksDescendants" to the root level of the xml layout like below:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_margin="4dp"
android:descendantFocusability="blocksDescendants"<!--This is the line i'm talking about-->
android:background="#drawable/rounded_border_layout"
android:layout_height="wrap_content">
<LinearLayout
android:orientation="vertical"
android:layout_width="40dp"
android:layout_marginRight="10dp"
android:id="#+id/review_main_user_image_layout"
android:layout_marginLeft="10dp"
android:layout_height="54dp">
<ImageView
android:layout_width="40dp"
android:id="#+id/review_main_user_image"
android:background="#drawable/reviews_x_trail_user_image_border"
android:layout_height="40dp"
android:src="#drawable/ic_help_user" />
<TextView
android:typeface="monospace"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Me"
android:textSize="10sp"
android:layout_gravity="center"
android:singleLine="true"
android:id="#+id/review_main_user_name"
android:layout_below="#+id/review_main_user_image" />
</LinearLayout>
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/review_main_user_image_layout"
android:layout_toEndOf="#+id/review_main_user_image_layout">
<TextView
android:layout_marginLeft="8dp"
android:layout_width="wrap_content"
android:textColor="#color/black"
android:layout_height="wrap_content"
android:singleLine="true"
android:id="#+id/review_main_title"
android:text="Good Product For The Price"/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="8dp"
android:orientation="horizontal">
<RatingBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/review_main_rating"
android:progressDrawable="#drawable/apptheme_ratingbar_small_holo_light"
android:numStars="5"
style="?android:attr/ratingBarStyleSmall" />
<TextView
android:layout_marginLeft="8dp"
android:text="12-Jun-1993"
android:id="#+id/review_main_date"
android:layout_width="wrap_content"
android:layout_height="match_parent" />
</LinearLayout>
</LinearLayout>
</RelativeLayout>
That't it now in your adapter getView method you can implement on click listener for each widget you have in that layout.
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ReviewsXTrailViewHolder reviewsXTrailViewHolder;
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.list_row_review_main, parent, false);
TextView title = (TextView)convertView.findViewById(R.id.review_main_user_image);
//title.setOnclickListener()
return convertView;
}
In that above code i have added on click listener for textview.I hope it will work
Comment below if that doesn't work
I search a lot for an answer and didn't find one that suit me.
I found out that when I set my layout_heigh to 500dp -> all the item shown, but when it has normal size (layout_heigh=wrap_content) then only the first item is shown.
this is my code:
activity_main.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<Button
android:layout_width="match_parent"
android:layout_height="50dp"
android:text="Add Task"
android:onClick="addTask" />
<ListView android:id="#+id/myListView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawSelectorOnTop="false"/>
</LinearLayout>
xml_item.xml: this is for one item to duplicate in the listView
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:descendantFocusability="blocksDescendants">
<TextView
android:layout_width="100dp"
android:layout_height="50dp"
android:id="#+id/itemText"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:padding="15dp"
android:textSize="20sp" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/doneBtn"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="5dp"
android:text="Done" />
</RelativeLayout>
MyListAdapter: a class in the main_activity that extends the ArrayAdapter class so I can put in one row both TextView and a button.
private class MyListAdapter extends ArrayAdapter<String> {
private int layout;
public MyListAdapter(Context context, int resource, List<String> objects) {
super(context, resource, objects);
layout= resource;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder mainHolder= null;
if (convertView == null) {
LayoutInflater inflater = LayoutInflater.from(getContext());
convertView= inflater.inflate(layout, parent, false);
ViewHolder viewHolder= new ViewHolder();
viewHolder.item= (TextView) convertView.findViewById(R.id.itemText);
viewHolder.btn= (Button) convertView.findViewById(R.id.doneBtn);
viewHolder.btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getContext(), itemArray.get(position), Toast.LENGTH_SHORT).show();
}
});
convertView.setTag(viewHolder);
}
else {
mainHolder= (ViewHolder) convertView.getTag();
mainHolder.item.setText(getItem(position));
}
return convertView;
}
public class ViewHolder {
TextView item;
Button btn;
}
}
Thanks for all! :)
but when it has normal size (layout_heigh=wrap_content)
It is a very bad idea using a ListView by giving it a height=wrap_content.
This forces ListView to measure a few children out of the adapter at layout time, to know how big it should be.
You can check it your self debugging the getView() method inside the adapter.
In your case, using a LinearLayout just add a top margin (50dp as the Button) to your listView and use layout_heigh=match_parent.
Otherwise use a RelativeLayout.
Change your listview to take up as much room as is can considering the height of any sibling views (in this case your button). Here's how to do that with the android:layout_weight attribute
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<Button
android:layout_width="match_parent"
android:layout_height="50dp"
android:text="Add Task"
android:onClick="addTask" />
<ListView android:id="#+id/myListView"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1"
android:drawSelectorOnTop="false"/>
</LinearLayout>
I'm stumped. This one IS simple and I'm missing something simple but I'm just not getting anywhere.
I have a ListView that contains pretty simple items - TextView's that contain text of the form "N. name", where N is the position in the list and name is the name of the associated objects. I've created a ListAdapter that presents that information into the ListView.
The presentation stuff seems to work fine. It's the part where when I tap on a row that's not working. I just don't get a notification. If I set a onClickListener on the item (when it's generated in the Adapter) I do get a notification, but it's convoluted to make that work the way I'd like it to. I've tried a bunch of stuff - changing descendent focusability, enabling, disabling, setting itemsCanFocus to false, ... - but no luck on any of them.
I've included relevant code for configuring the view and the elements in the ListView.
In particular, what I'm trying to do is get that OnItemClickLister.onItemClick() to get invoked when I tap on a row. Any thoughts on what I'm doing wrong?
Activity:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
model = FZMModel.getInstance(this);
setContentView(R.layout.activity_deploy);

if (model.getProfiles().size() == 0) {
viewTitle.setText(R.string.deploy_header_create);
} else {
viewTitle.setText(R.string.deploy_header_choose);
}
profileListView = (ListView) findViewById(R.id.profileListView);
profileListAdapter = new ProfileListAdapter(this, model);
profileListView.setAdapter(profileListAdapter);
profileListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override

Log.d(TAG, String.format("Item %d selected (with id=0x%x)", position, id));
}

in the textview of your inflator layout just add:
android:focusable="false"
android:focusableInTouchMode="false"
and in parent layout of your inflator i.e in relative layout of inflator add:
android:descendantFocusability="blocksDescendants"
remove :
android:descendantFocusability="beforeDescendants"
from your listview. and set height of your listview to match_parent will solve your issue.
remove following attributes from your ListView:
android:choiceMode="none"
android:clickable="true"
android:descendantFocusability="beforeDescendants"
also
android:layout_width="wrap_content"
android:layout_height="wrap_content"
makes no sense in this context (especially height)

and i'm setting an onItemClickedListener:
private void setGridView()
{
//create a new event list
picoEventsList = new ArrayList<PicoEvent>();
//create new gridview arrayadapter
arrayAdapter = new EventDetailsArrayAdapter(getActivity(), picoEventsList);
//set grid's view empty view
View emptyView = LayoutInflater.from(getActivity()).inflate(R.layout.fragment_events_empty_view, null);
gridView.setEmptyView(emptyView);
gridView.setOnItemClickListener(this);
gridView.setAdapter(arrayAdapter);
}
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
//get clicked event
PicoEvent event = arrayAdapter.getItem(arg2);
//create new event details fragment
EventDetailsFragment eventDetailsFragment = new EventDetailsFragment();
//add the event to fragment's arguments
eventDetailsFragment.setArguments(PicoEventCreator.createBundle(event));
//show the event details fragment
getMainActivity().showFragment(null, eventDetailsFragment, true, true);
}
but the onItemClick() method doesn't get fired..
I've checked and non of my views in my layout has clickable="true" setted...
Any ideas ?
Hey guyz finally got a solution...
what we were doing is directly accessing the Layout inside the GridView, so the onItemClickListener finds it confusing to access the item.
So the solution is to apply the onClickListener inside the Adapter (i.e. normally ArrayAdapter)
so what i m trying to say is:
public View getView(int position, View convertView, ViewGroup parent) {
//Here row is a view and we can set OnClickListener on this
final View row;
ViewHolder holder = null;
if (convertView == null) {
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
//Here we inflate the layout to view (linear in my case)
row = inflater.inflate(layoutResourceId, parent, false);
holder = new ViewHolder();
holder.imageTitle = (TextView) row.findViewById(R.id.text);
holder.image = (ImageView) row.findViewById(R.id.image);
row.setTag(holder);
} else {
row = convertView;
holder = (ViewHolder) row.getTag();
}
ImageItem item = data.get(position);
holder.imageTitle.setText(item.getTitle());
holder.image.setImageBitmap(item.getImage());
//Now get the id or whatever needed
row.setId(position);
// Now set the onClickListener
row.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(context, "Clicked" + row.getId() + "!!",
Toast.LENGTH_SHORT).show();
}
});
return row;
}
Ok i found what the problem was
Apparently GridView and HorzonitalScrollView are not such good friends...
probably because the HorzonitalScrollView has onClick funcionality..
The solution i found is to put:
android:descendantFocusability="blocksDescendants"
in my ArrayAdapter root view.
