Can't click on element in ListView Android

I am trying to create a custom list. My list is contained in a Fragment that correctly implements onScrollListener and populates the list using an adapter. The problem is that I cannot click on each item and I cannot figure out why. Here there is the code of my layout fragment
<?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"
android:clickable="true">
<ListView
android:id="#+id/listNotification"
android:scrollbars="none"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:footerDividersEnabled="false"
android:headerDividersEnabled="false"
android:paddingStart="15dp"
android:paddingEnd="15dp"
android:clickable="true"
/>
</LinearLayout>
and here there is the code of my custom list
<?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"

here there is the code that creates my list using the adapter and setting the onclicklistener
adapter = new NotificationListAdapter(getActivity(), this.rows);
list = (ListView) firstAccessView.findViewById(R.id.listNotification);
list.setAdapter(adapter);
list.setOnScrollListener(this);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
if(adapter.getItem(position).getTypeNotification()==0) {
mNotificationInteface.readQuestion(adapter.getItem(position).getQuestionId());
}
if(adapter.getItem(position).getTypeNotification()==1){
mNotificationInteface.readAnswer(adapter.getItem(position).getQuestionId());
}
}
});
and here there is the code of my adapter
public class NotificationListAdapter extends ArrayAdapter<NotificationItem> {
private View view;
private final Activity context;
private List<NotificationItem> rows;
private int count = 1;
public NotificationListAdapter(Activity context, List<NotificationItem> firstRows ) {
super(context, R.layout.list_notifications, firstRows);
this.context = context;
this.rows = firstRows;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
LayoutInflater inflater = context.getLayoutInflater();
view = inflater.inflate(R.layout.list_notifications, null);
view.setPadding(0,10,0,10);
holder = new ViewHolder();
holder.textNotification = (TextView) view.findViewById(R.id.textNotification);
holder.idQuestion = (TextView) view.findViewById(R.id.idQuestion);
holder.typeNotification = (TextView) view.findViewById(R.id.typeNotification);
holder.imageNotification = (ImageView) view.findViewById(R.id.imageNotification);
view.setTag(holder);
} else {
view=convertView;
holder = (ViewHolder) convertView.getTag();
}
int typeNotification = this.rows.get(position).getTypeNotification();
holder.textNotification.setTextColor(Color.BLACK);
holder.idQuestion.setText(String.valueOf(this.rows.get(position).getQuestionId()));
holder.typeNotification.setText(String.valueOf(this.rows.get(position).getTypeNotification()));
if(typeNotification==0){
holder.textNotification.setText(R.string.askQuestion);
holder.imageNotification.setImageResource(R.mipmap.iconuseranonymous);
}
if(typeNotification==1){
//nome da recuperare da con id notifica, quindi id utente quindi dome

Picasso.with(context).load("http://i.imgur.com/DvpvklR.png").transform(new CircleTransform()).fit().centerCrop().into(holder.imageNotification);
}
if(typeNotification==2){
//nome e immagine da recuperare
holder.textNotification.setText(R.string.newFriend);
Picasso.with(context).load("http://i.imgur.com/DvpvklR.png").transform(new CircleTransform()).fit().centerCrop().into(holder.imageNotification);
}
return view;
}
#Override

}
public void setCount(int count) {

Remove android:clickable="true" from the ListView and it's parent in your XML layout, and also from the root of your list item layout.

I will add something else if necessary. may have a library ready?

Change your ImageView by click gridview item:
gridView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
ViewHolder holder = (ViewHolder)view.getTag();
//set your new image here
holder.imageview.setImageResource(R.id.yourImage);
... ...
//maybe also update items content in 'position' if need
}
});
Hope this help!

Check box selection and list item click on the same listview in android

I have implemented a custom listview with checkboxes in the single choice mode of the android listview.I want a functionality such that when I click on the checkbox the row corresponding to that check box must get added(or rather say the "Person" object shown in that row should get added to another list and be removed from that list) and on itemclick on that listview should take me to another screen in android.I tried the other ways but they specify that the checkbox needs to be focasable:false.Also I want the click listener to work on the check box only.Please any suggestions or help on these.Thanks in advance
This id the xml code.
<?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" >
<CheckBox
android:id="#+id/projects_check"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:layout_marginBottom="5dp"
android:layout_marginLeft="5dp"
android:layout_marginStart="5dp"
android:layout_marginTop="5dp"
android:focusable="false" />
<TextView
android:id="#+id/project_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#+id/projects_check"
android:layout_alignBottom="#+id/projects_check"
android:layout_marginLeft="10dp"
android:layout_marginStart="10dp"
android:layout_toEndOf="#+id/projects_check"
android:layout_toRightOf="#+id/projects_check"
android:text="TextView" />
</RelativeLayout>
And this is my onitem click listener code..
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long arg3) {
Projects info = (Projects) parent.getItemAtPosition(position);
info.toggleChecked();
ProjectsHolder viewHolder = (ProjectsHolder) view.getTag();
viewHolder.getmChoiceSelect().setChecked(info.isChecked());
if (viewHolder.getmChoiceSelect().isChecked()) {
completed_projects.add(info);
mCompProjAdapter.notifyDataSetChanged();
projects_list.remove(info);
mProjAdapter.notifyDataSetChanged();
}
}

To manage click onto the row itself, you can just write listener for listView itself.
This is how i manage checkbox click.
class CustomAdapter extends ArrayAdapter<BeanClass> {
private ArrayList<BeanClass> items;
public FieldPlannedAdapter(Context context,
ArrayList<BeanClass> items) {
super(context, R.layout.custom_list_row, items);
this.items = items;
}
public class ViewHolder {
protected CheckBox checkbox;
protected TextView name;
}
#Override
public View getView(final int position, View convertView,
ViewGroup parent) {
final ViewHolder viewHolder;
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) getActivity()
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.custom_list_row,
null);
viewHolder = new ViewHolder();
viewHolder.checkbox = (CheckBox) convertView
.findViewById(R.id.checkIsMissed);
viewHolder.name = (TextView) convertView
.findViewById(R.id.txtViewMTPname);
convertView.setTag(viewHolder);
viewHolder.checkbox
.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
final CheckBox cb = (CheckBox) v;
final BeanClass item = (BeanClass) cb
.getTag();
item.setSelected(cb.isChecked());
if (cb.isChecked()) {
// DO SOMETHING
} else {
}
}
});
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
BeanClass item = items.get(position);
viewHolder.name.setTag(item);
viewHolder.checkbox.setTag(item);
viewHolder.name.setText(item.getName());
viewHolder.checkbox.setChecked(item.isSelected());
if (viewHolder.checkbox.isChecked()) {
// DO SOMETHING
} else {
// DO SOMETHING
}
return convertView;
}
}

ListView Rows can't be inflated

I am very new in Android and I'm trying to make a table for my application. I use listview and a custom adapter to populate 9 data in a row. I thought that it should work, but the listview element is not shown when I run the application. Thank you for your help
Here is the part of my adapter class which I believe that have some problems:
EDIT
public class PlayerAdapter extends BaseAdapter {
ArrayList<Player> PlayerList;
private Context mContext;
public PlayerAdapter(Context c,ArrayList<Player> List) {
mContext = c;
PlayerList=List;
}
public int getCount() {
return PlayerList.size();
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return PlayerList.get(position);
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return PlayerList.indexOf(getItem(position));
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View rowView = convertView;
ViewHolder viewHolder = null;
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if(convertView == null) {
rowView = inflater.inflate(R.layout.list_view_activity, parent, false);

viewHolder.text9 = (TextView) rowView.findViewById(R.id.textView10);
rowView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
viewHolder.text1.setText(PlayerList.get(position)._name);
viewHolder.text2.setText(""+PlayerList.get(position)._play);
viewHolder.text3.setText(""+PlayerList.get(position)._win);

viewHolder.text7.setText(""+PlayerList.get(position)._GF);
viewHolder.text8.setText(""+PlayerList.get(position)._GA);
viewHolder.text9.setText(""+PlayerList.get(position)._PTS);
// set text for other TextViews too if u want to set value for each TextView I only show for 1st one
return rowView;
}
private class ViewHolder {
TextView text1;
TextView text2;
TextView text3;
TextView text4;
TextView text5;
TextView text6;

Here is my main program:
ArrayList<Player> PlayerList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
PlayerList = new ArrayList<Player>();
PlayerList.add(new Player("BER"));
PlayerList.add(new Player("DOM"));
PlayerList.add(new Player("FER"));
PlayerList.add(new Player("HEN"));
PlayerList.add(new Player("GAR"));
PlayerList.add(new Player("JER"));
PlayerList.add(new Player("JON"));
PlayerList.add(new Player("IRV"));
PlayerList.add(new Player("LIM"));
ListView listView = (ListView) findViewById(R.id.player_list);
listView.setAdapter(new PlayerAdapter(this,PlayerList));
}
And, here is the Player Class:
ADDED
public class Player {
String _name;

Remove that for loop, get view method will take care of looping itself..
EDIT
You must initilize all the 10 textviews then only if you loop through will apply the text..
so initilize all 10 textviews outside the loop..

getView() is called for each row in the array you supplied to adapter. Hence you need to apply a loop in getView().
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.list_view_activity, parent, false);
TextView textView;
textView = (TextView) rowView.findViewById(tv[i]);
textView.setText(playerArray[position]._name);
return rowView;
}
*Note: Also you need to make only row-layout, like in your case it seems you want to display every row with a single textview. Hence, your R.layout.list_view_activity should contain a textView only.
Say textView in R.layout.list_view_activity has id description. So following change would be needed.
textView = (TextView) rowView.findViewById();

public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.list_view_activity, parent, null);
TextView textView;
// **for(int i=0;i<9;i++){// Remove this for loop inside your code**
textView = (TextView) rowView.findViewById(tv[position]);
textView.setText(playerArray[position]._name);
// }
return rowView;
}

Don't have to declare int[] tv
int[] tv = {R.id.textView2,R.id.textView3,R.id.textView4,R.id.textView5,R.id.textView6
,R.id.textView7,R.id.textView8,R.id.textView9,R.id.textView10};
and for loop
for(int i=0;i<9;i++){
textView = (TextView) rowView.findViewById(tv[i]);
textView.setText(playerArray[position]._name);
}
Changes u have to do
1. In getItemId(int position) u returning null return the position like this
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
2. In getItem(int position) u returning null return the specific position of ur array like this
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return playerArray[position];
}
3. In getView(int position, View convertView, ViewGroup parent) do something like this and try to follow ViewHolder pattern
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder;
View rowView = convertView;
if(rowView == null) {
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.list_view_activity, parent, false);
viewHolder = new ViewHolder();
viewHolder.text1 = (TextView) rowView.findViewById(R.id.textView2);
viewHolder.text2 = (TextView) rowView.findViewById(R.id.textView3);
viewHolder.text3 = (TextView) rowView.findViewById(R.id.textView4);
viewHolder.text4 = (TextView) rowView.findViewById(R.id.textView5);

Button under a couple of Textviews

I'm doing something quite similar to the tutorial http://www.vogella.com/articles/AndroidListView/article.html#listadvanced_interactive.
I now want to put a button at the bottom. Then click the button and do something with the selected Values.
I understand, that I need some new layout, because adding the button to the existing one would just add a button to every textview. But I cant figure out how to do it.
Some help would be very nice. Thanks in advance. :)
Edit: That's my layout at the moment.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#+id/label"
android:textSize="30px" >
</TextView>
<CheckBox
android:id="#+id/check"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_marginLeft="4px"
android:layout_marginRight="10px" >
</CheckBox>
</RelativeLayout>
This creates something that looks like this:
http://i.stack.imgur.com/cN8Dl.png
My adapter looks like this:
public class AttributeAdapter extends ArrayAdapter<Attribute> {
private final List<Attribute> list;
private final Activity context;
public AttributeAdapter(Activity context, List<Attribute> list) {
super(context, R.layout.activity_select_attributes, list);
this.context = context;
this.list = list;
}
static class ViewHolder {
protected TextView text;
protected CheckBox checkbox;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = null;
if (convertView == null) {
LayoutInflater inflator = context.getLayoutInflater();
view = inflator.inflate(R.layout.activity_select_attributes, null);
final ViewHolder viewHolder = new ViewHolder();
viewHolder.text = (TextView) view.findViewById(R.id.label);
viewHolder.checkbox = (CheckBox) view.findViewById(R.id.check);
viewHolder.checkbox
.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
Attribute element = (Attribute) viewHolder.checkbox
.getTag();
element.setSelected(buttonView.isChecked());
}
});
view.setTag(viewHolder);
viewHolder.checkbox.setTag(list.get(position));
} else {
view = convertView;
((ViewHolder) view.getTag()).checkbox.setTag(list.get(position));
}
ViewHolder holder = (ViewHolder) view.getTag();
holder.text.setText(list.get(position).getName() + " " + list.get(position).getType());
holder.checkbox.setChecked(list.get(position).isSelected());
return view;
}
Now i want a button at the bottom to continue with the selected values.

Create a new layout or xml file named activity_base and add following:
<RelativeLayout 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"
tools:context=".BaseActivity" >
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/button1"
>
</ListView>
<Button
android:id="#+id/button1"
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:text="Button" />
</RelativeLayout>
in your ListActivity in the Oncreate add setContentView(R.layout.activity_base);
This should do the job.
