I implemented my custom list but when I click an element of my list a Toast message should be displayed. It looks like that the setOnItemClickListener does not work.
Here there is the code of of my fragment layout in which there is my ListView
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff">
<ListView
android:id="#+id/listSearch"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:footerDividersEnabled="false"
android:headerDividersEnabled="false"
android:paddingStart="15dp"
android:paddingEnd="15dp"
android:focusable="false"/>
</LinearLayout>
here there is the structure of my list (each single line)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
>
<LinearLayout android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<ImageView
android:id="#+id/imageContact"
android:layout_width="60dp"
android:layout_height="60dp"
android:padding="5dp"
android:focusable="false"/>
<TextView
android:id="#+id/nameSurnameContact"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceSmall"
android:layout_marginLeft="10dp"
android:layout_marginTop="5dp"
android:padding="2dp"
android:textColor="#33CC33"
android:focusable="false"/>
<TextView
android:id="#+id/idContact"
android:layout_width="match_parent"
android:layout_height="0dp"
android:visibility="invisible"
android:focusable="false"
/>
</LinearLayout>
</LinearLayout>
and here there is the mothod of my fragment that creates the layout and populate the list
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedBundle) {
View firstAccessView;
if(savedBundle==null) {
firstAccessView = inflater.inflate(R.layout.search_fragment_layout, null);
for(int i=0; i<8; i++){
Contact c = new Contact(idContact[i], nameSurname[i], facebookId[i], timeStamp[i]);
this.rows.add(c);
}
adapter = new SearchListAdapter(getActivity(), this.rows);
list = (ListView) firstAccessView.findViewById(R.id.listSearch);
list.setAdapter(adapter);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Toast.makeText(getActivity().getApplicationContext(), "item selected", Toast.LENGTH_SHORT).show();
}
});
list.setOnScrollListener(this);
}else{
firstAccessView = getView();
}
return firstAccessView;
}
is there something that I missed in the xml files of in the Fragment file?
Remove android:focusable="false" from ListView.
android:focusable="false"
Remove this line from your listview xml file

i am trying to make list view with clickable items, and every list_item must consist 2 clickable buttons.
But if i add buttons to item layout, iten click listener stops to work...
here is my item_layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:gravity="center">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5dp">
<com.pkmmte.view.CircularImageView
android:id="#+id/friends_new_photo_circularImageView"
android:layout_gravity="center"
android:layout_width="#dimen/user_friends_width"
android:layout_height="#dimen/user_friends_height"
android:src="#mipmap/ic_launcher"
app:border="true"
app:border_color="#EEEEEE"
app:border_width="2dp"
app:shadow="true"/>
<ImageView
android:id="#+id/friends_new_online_status_imageview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/online_status"
android:layout_alignBottom="#+id/friends_new_photo_circularImageView"
android:layout_alignRight="#+id/friends_new_photo_circularImageView"
android:layout_marginRight="8dp"
android:layout_marginBottom="5dp"/>
</RelativeLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_weight="1">
<TextView
android:id="#+id/friends_new_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="18sp"
android:textStyle="bold"/>
<ImageView
android:id="#+id/friends_new_rating"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:src="#drawable/stars"/>
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<Button
android:layout_width="wrap_content"
android:layout_height="35dp"
android:onClick="true"
android:text="Add"/>
<Button
android:layout_width="wrap_content"
android:layout_height="35dp"
android:onClick="true"
android:text="Dismiss"/>
</LinearLayout>
</LinearLayout>
here is fragment layout (with listView):
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#+id/listview_friends"
android:layout_width="match_parent"
android:layout_height="wrap_content"
style="#style/ListViewStyle"/>
</LinearLayout>
and here is my fragment with onCreateView and onItemClickListener:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_friends_listview, container, false);
ButterKnife.inject(this, rootView);
String[] mNames = {
"Example 1",
"Example 2"
};
mFriendsAdapter = new FriendsAdapter(getActivity(), null, 0);
List<String> mList = new ArrayList<>(Arrays.asList(mNames));
ArrayAdapter<String> mAdapter = new ArrayAdapter<String>(
getActivity(),
R.layout.list_item_friends_new,
R.id.friends_new_name,
mList
);
mListView.setOnItemClickListener(this);
mListView.setAdapter(mAdapter);
return rootView;
}
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
FriendsFragment.openCurrentUser(getActivity());
}
So here is the question:
is it possible to make clickable listItems with clickable buttons?
and if its true, than how to do it? if it false - maybe you have some other solution?
I just found solution from here..but by deep clicking...
If any row item of list contains focusable or clickable view then OnItemClickListener won't work.
The row item must have a param like android:descendantFocusability="blocksDescendants".
here you can see example, how your list item should look like
row_item.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:baselineAligned="false"
android:descendantFocusability="blocksDescendants"
android:gravity="center_vertical" >
// your other widgets here
</LinearLayout>
or add these two lines for the inner views
android:focusable="false"
android:focusableInTouchMode="false"
remove onclick attribute like bellow in your code...
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<Button
android:layout_width="wrap_content"
android:layout_height="35dp"
android:onClick="true"//remove this
android:text="Add"/>
<Button
android:layout_width="wrap_content"
android:layout_height="35dp"
android:onClick="true" //remove this
android:text="Dismiss"/>
</LinearLayout>
and write your adapter as
ArrayAdapter<String> mAdapter = new ArrayAdapter<String>(
getActivity(),
R.layout.list_item_friends_new,
R.id.friends_new_name,
mList
){
View.OnClickListener listener = new View.OnClickListener() {
#Override
public void onClick(View v) {
//your action on button click
}
};
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = super.getView(position, convertView, parent);
Button button = (Button) view.findViewById(R.id.yourButtonID);
button.setOnClickListener(listener);
return view;
}
};
I checked all the previous questions regarding this issue , but none of them are helpfull to me .
My listview is not responding , i tried changing this
list.setOnItemClickListener(new ContactsListItemClickListener(this));
to
list.setOnItemClickListener(this);
by making my PrioritiseContacts activity just imeplement OnItemClickListener , but then too its not working .
The activity is successfully running , but i am unable to listen for listclick events.
How to correct this?
Here is my class :
public class PrioritiseContacts extends Activity implements OnClickListener {
private ListView list;
// list of contacts with name
private List<Contacts> contactsList;
private Controller controll;
private ContactListAdapters adapter;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.select_contacts);
controll = new Controller();
contactsList = controll.fetchContacts(this);
// call the adapter to set the list view layout
adapter = new ContactListAdapters(contactsList, this);
list = (ListView) findViewById(R.id.lv_contacts);
// set the adapter to list
list.setAdapter(adapter);
list.setOnItemClickListener(new ContactsListItemClickListener(this));
// inflate the list of contact
}
#Override
public void onClick(View arg0) {
Toast.makeText(this, "clicked", 1000).show();
}
class ContactsListItemClickListener implements OnItemClickListener {
private Context c;
public ContactsListItemClickListener(
PrioritiseContacts prioritiseContacts) {
this.c = prioritiseContacts;
}
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
Toast.makeText(c, "Clicked", 1500).show();
System.out.print("clicked");
}
}
}
My select_contacts xml :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#000000"
android:orientation="vertical">
<TextView
android:id="#+id/tv_select_contacts"
android:layout_width="match_parent"
android:layout_height="wrap_content"

android:clickable="true"
android:focusable="true"
android:divider="#android:color/transparent"
android:dividerHeight="10.0sp"
android:scrollbars="none" >

</LinearLayout>
And this is my adapter's getview() :
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
// layout infklater to inflate the post list view
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
view = inflater.inflate(R.layout.contacts_list_view, null);
}
Contacts c = contactList.get(position);
// set text views in contact lists
// Typeface custom_font =
// Typeface.createFromAsset(context.getAssets(),"fonts/calibril.ttf");
TextView name = (TextView) view.findViewById(R.id.tv_contact_name);
// date.setTypeface(custom_font);
name.setText(c.getName());
TextView number = (TextView) view.findViewById(R.id.tv_number);
// title.setTypeface(custom_font);
number.setText(c.getPhone());
ImageView contact_image = (ImageView) view.findViewById(R.id.iv_single_contact);
// hut.setTypeface(custom_font);
if(c.getContactImage() != null)
contact_image.setImageBitmap(c.getContactImage());
else
contact_image.setImageDrawable(view.getResources().getDrawable(R.drawable.ic_contact_picture_2));
return view;
}
My contacts_list_view xml :

If any row item of list contains focusable or clickable view then OnItemClickListener won't work such as for checkbox or button etc in the row item.There are two solution:
1. row item must be having param like android:descendantFocusability="blocksDescendants"
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:baselineAligned="false"
android:descendantFocusability="blocksDescendants"
android:gravity="center_vertical" >
// your other widgets here
</LinearLayout>
2. Set given two attributes to false
like
android:focusable="false"
android:focusableInTouchMode="false"
For example if there is any checkbox or button or image in the row item then
<CheckBox
android:id="#+id/fav_check_box"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="false" />

I can not solve the problem with not working setOnItemClickListener().

Maybe I tried too many things and make my code not clear
You must delete this.
android: enfocable = "false"
android: focusableInTouchMode = "false"
//try with this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:baselineAligned="false"
android:gravity="center_vertical" >
<ListView
android:id="#+id/listViewCategories"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
/>
<LinearLayout/>
if you will specify the listview that events happen to the children, you will not click on item
I solved this.
I changed this fragment:
categoriesListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
}
});
I am having problems with ListView on android. I have an Activity with an EditText view and a button. The idea is user should enter some info in the EditText field, touch the Search button which retrieves a list from a web service that it is displayed in the same activity below the EditText and the Button. Everything fine, I got the data from Internet but items weren't displaying. I was using the notifyDataSetChanged(). After a couple of hours with no success, I decided trying to put some items manually and it turns out that again nothing was displayed, hence I think I am doing something wrong when I am trying to set the listview and the adapter. So here is the code..
the xml of the activity activity_search.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"

android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_margin="5dp">
<TextView
android:id="#+id/row_code"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/Common_TextContent"
android:textAppearance="#android:style/TextAppearance.Holo.Medium" />
<TextView
android:id="#+id/row_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:text="#string/Common_TextContent"
android:textAppearance="#android:style/TextAppearance.Holo.Small" /></LinearLayout>
the custom Adapter:
public class ItemsListAdapter extends ArrayAdapter<ItemsList> {
private int[] colors = new int[] { 0x30ffffff, 0x30808080 };
public AssetListAdapter(Context context,
List<ItemsList> itemsList) {
super(context, 0, itemsList);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = LayoutInflater.from(getContext()).inflate(R.layout.row, null);
}
convertView.setBackgroundColor(colors[position % colors.length]);
TextView code = (TextView) convertView.findViewById(R.id.row_code);
code.setText(getItem(position).getCode());
TextView name = (TextView) convertView.findViewById(R.id.row_name);
name.setText(getItem(position).getName());
return convertView;
}
and the onCreate method on the Activity
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search);
_listView = (ListView) findViewById(R.id.listview_items);
_listItems = new ArrayList<ItemsList>();
_listItems.add(new ItemsList ("cosa1", "cosa1", "cosa1", "cosa1"));
_listItems.add(new ItemsList ("cosa2", "cosa2", "cosa2", "cosa2"));
_listItems.add(new ItemsList ("cosa3", "cosa3", "cosa3", "cosa3"));
_adapter = new ItemsListAdapter(this, _listItems);
_listView.setAdapter(_adapter);
}
The ItemsList is just an Object with 4 strings with all the getters implemented.
When I debug in the getView method of the Adapter, the view (convertView) is created and it has the right information. It is just that is not showing those in the screen. What am I doing wrong?
Thanks...
Your second LinearLayout has a height of match_parent. Try wrap_content instead.
