Android: OnItemClickListener does not work

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

Android: How to inflate different layout from different buttons?

I trying to do making something tabs but using button.
but each time I click on button it add me a row.
I want it to change the all layout to another..
MainActivity
public class MainActivity extends Activity {
Button btn1;
Button btn2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn1 = (Button) findViewById(R.id.button1);
btn1.setOnClickListener(switchListener);
btn2 = (Button) findViewById(R.id.button2);
btn2.setOnClickListener(switchListener);
}
private OnClickListener switchListener = new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
//ScrollView sv = (ScrollView) findViewById(R.id.MyScrollView);
LinearLayout ll = (LinearLayout) findViewById(R.id.MyLinearLayout);
LayoutInflater inflater = LayoutInflater
.from(getApplicationContext());
if (btn1 == v) {
View v1 = inflater.inflate(R.layout.firstview, null);
ll.addView(v1);
} else {
View v2 = getLayoutInflater().inflate(R.layout.secondview, null);
ll.addView(v2);
}
}
};
}
and here my Main XML file
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TableRow
android:id="#+id/tableRow1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Layout 1" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Layout 2" />
</TableRow>
<TableRow
android:id="#+id/tableRow2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1" >
<ScrollView
android:id="#+id/MyScrollView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1" >
<LinearLayout
android:id="#+id/MyLinearLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
</TableRow>
and here my other two layouts that I want to inflate
<LinearLayout 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/textView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="First View"
android:textAppearance="?android:attr/textAppearanceLarge"
android:gravity="center"
android:background="#android:color/holo_blue_light"/>
and the second
<LinearLayout 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/textView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Second View"
android:textAppearance="?android:attr/textAppearanceLarge"
android:gravity="center"
android:background="#android:color/holo_red_light"/>

First make match parent your tableview.
and now do below on your code:-
if(ll.getChildCount() > 0) {
ll.removeAllViews();
}
if (btn1 == v) {
View v1 = inflater.inflate(R.layout.firstview, null);
ll.addView(v1);
} else {
View v2 = getLayoutInflater().inflate(R.layout.secondview, null);
ll.addView(v2);
}
the problem is you are just adding child on layout one by one so you need to remove first then add into layout so try above code.

before adding views to your ll linear layout check, as
if(ll.getChildCount() > 0) {
ll.removeAllViews();
}
then perform:
ll.addView(view) v1 or v2 as required.

ListView with footer in Android

In my Android application, I want to add footer to the ListView.
listfooter.xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:gravity="center_horizontal"
android:padding="3dp"
android:layout_height="fill_parent">
<TextView
android:id="#+id/getmore"
android:layout_width="wrap_content"
android:layout_height="50dp"
android:gravity="center"
android:textSize="16dp"
android:textColor="#D61E5C"
android:text="Load More"
android:textStyle="bold"/>
</RelativeLayout>
This is my main.xml file:
<?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:background="#color/white"
android:orientation="vertical" >
<ListView
android:id="#+id/expecters_listView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#id/first_view"
android:layout_marginTop="2dp"
android:divider="#A9A9A9"
android:dividerHeight="0.5dp"
android:fadingEdge="none"
android:paddingLeft="0dp"
android:paddingRight="0dp"
android:scrollbarStyle="outsideOverlay"
android:scrollbarThumbVertical="#drawable/scroll_thumb"
android:smoothScrollbar="true" />
</RelativeLayout>
This is my Activity class, MainActivity.java:
public class BestExpectersActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
expecters_listView = (ListView)findViewById(R.id.expecters_listView);
footerView = ((LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE))
.inflate(R.layout.listfooter, null, true);
//after getting the result
//set the direct messages to list view
expectersAdapter = new BestExpectersAdapter(BestExpectersActivity.this, remindersResult);
expecters_listView.setAdapter(expectersAdapter);
//set the footer
expecters_listView.addFooterView(footerView);
}
}
List is visible with some items, But footer is not visible (not adding to the ListView).

Try to Add footer before setAdapter like following code.
//set the footer
expecters_listView.addFooterView(footerView);
expecters_listView.setAdapter(expectersAdapter);
I hope this will help you.

Android RelativeLayout and OnClickListener

I found many many threads and answers on how to make a Relative layout respond to click event. I've implemented my layout according to them. But still OnClickListener is not called. I have also given selector for it and it works well.
my_list_item xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res/air.com.jingit.mobile"
android:layout_width="match_parent" android:layout_height="#dimen/actionBarHeight"
android:clickable="true"
android:background="#drawable/my_list_selector">
<com.loopj.android.image.SmartImageView
android:layout_width="#dimen/actionBarHeight"
android:layout_height="#dimen/actionBarHeight"
android:id="#+id/image"
android:scaleType="fitCenter"
android:layout_marginLeft="20dp"
android:clickable="false"
android:focusable="false"/>
<com.uma.mobile.view.CustomTextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Loading..."
android:id="#+id/userName"
app:typeface="fonts/HelveticaNeue"
app:customStyle="Regular"
android:textSize="20sp"
android:layout_centerVertical="true"
android:layout_toRightOf="#+id/image"
android:paddingTop="5dp"
android:paddingBottom="5dp"
android:textColor="#000"
android:clickable="false"
android:focusable="false"/>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#aaa"
android:layout_alignBottom="#+id/image"></FrameLayout>
and this is where I inflate the view:
public MyListItem(final Context context, final Integer retailerId) {
super(context);
LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = layoutInflater.inflate(R.layout.my_list_item, this);
image = (SmartImageView) view.findViewById(R.id.image);
userName = (CustomTextView) view.findViewById(R.id.userName);
setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Log.i("INSIDE LIST","CLICK");
}
});
}
Edit 1:
This Relative layout is added to a linear layout which is inside a scrollview, so that it works like a list view. Does this has something to do???
list_view.xml
<?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="wrap_content"
android:background="#eee">
<ScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/scrollView" >
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/listContainer" />
</ScrollView>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/imageView"
android:layout_centerHorizontal="true"
android:src="#drawable/up_indicator"
android:layout_alignBottom="#+id/scrollView" />

Once i had a RelativeLayout not firing onClick event and it was because i had a Button in the middle of it, and the Button's onClick event was being fired, instead of the RelativeLayout one. Solved it implementing a listener for both of them:
OnClickListener listener = new OnClickListener() {
public void onClick(View v) {
//Handle onClick
}
};
relativeLayout.setOnClickListener(listener);
button.setOnClickListener(listener);
Hope it helps!

Add OnClickListener in your RelativeLayout java Class

android: display data in xml

I want to create a game list wherein the game details like opponent name,score,etc will be displayed.I am having problem fetching the data into xml and then displaying it.please help.
I have created two xml.I have to set data into the 2nd xml and then include that 2nd xml into 1st xml.
my 1st xml is
<FrameLayout
android:id="#+id/gameListFrame"
android:layout_width="fill_parent"
android:layout_height="380dp"
android:orientation="vertical" >
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="5dip" >
<LinearLayout
android:id="#+id/GameListHolder"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#color/scrollBackG"
android:orientation="horizontal" >
</LinearLayout>
</ScrollView>
</FrameLayout>
2nd xml is
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/gamelist_items"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true"
android:orientation="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="50px"
android:gravity="left"
android:orientation="horizontal"
android:background="#FFF" >
<ImageView
android:id="#+id/gl_avatar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher" />
<LinearLayout android:orientation="horizontal"
android:layout_width="225px"
android:layout_height="fill_parent"
android:gravity="left"
android:background="#000">
<LinearLayout android:orientation="vertical"
android:layout_width="175px"
android:layout_height="wrap_content"
android:gravity="top">
<TextView android:id="#+id/oppName"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<LinearLayout android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="top" >
<TextView android:id="#+id/lastWord"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<TextView android:id="#+id/diffTime"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</LinearLayout>
</LinearLayout>
</LinearLayout>
</LinearLayout>
</LinearLayout>
My code is
gameListItem=(LinearLayout) findViewById(R.id.gamelist_items);
for (i=0;i<gamelistVector.size();i++)
{
rowView=View.inflate(context, R.layout.gamelist_details,null );
TextView oppName=(TextView) rowView.findViewById(R.id.oppName);
TextView lastWord=(TextView) rowView.findViewById(R.id.lastWord);
TextView diffTime=(TextView) rowView.findViewById(R.id.diffTime);
oppName.setText(gList.getOppName());
lastWord.setText(gList.getOppLastWord());
diffTime.setText(gList.getDiffTime()+"hr");
gameListItem.addView(rowView); //show the total games}

You need to extend ListAdapter and override the getView() method that sets the data for each row.
See this example

You need inflater reference to inflate views.
To GetInflater reference use:
LayoutInflater inflater = (LayoutInflater)context.getSystemService
(Context.LAYOUT_INFLATER_SERVICE);
gameListItem=(LinearLayout) findViewById(R.id.gamelist_items);
for (i=0;i<gamelistVector.size();i++)
{
rowView=inflater.inflate(R.layout.gamelist_details, null);
TextView oppName=(TextView) rowView.findViewById(R.id.oppName);
TextView lastWord=(TextView) rowView.findViewById(R.id.lastWord);
TextView diffTime=(TextView) rowView.findViewById(R.id.diffTime);
oppName.setText(gList.getOppName());
lastWord.setText(gList.getOppLastWord());
diffTime.setText(gList.getDiffTime()+"hr");
gameListItem.addView(rowView); //show the total games
}

thanks guys 4 answering to my query...i saw ur suggestions and figured a way out.this is wat i did nd its working...
private void doDisplay(){
this.runOnUiThread(new Thread() {
#Override
public void run() {
TextView gameCount=(TextView) findViewById(R.id.game_count);
gameCount.setText(" found "+maxGames+" games ");
for (i=0;i<gamelistVector.size();i++)
{
rowView=View.inflate(context, R.layout.gamelist_details, null);
TextView oppName=(TextView) rowView.findViewById(R.id.oppName);
TextView lastWord=(TextView) rowView.findViewById(R.id.lastWord);
TextView diffTime=(TextView) rowView.findViewById(R.id.diffTime);
TextView score=(TextView) rowView.findViewById(R.id.opplastMoveScore);
oppName.setText(" "+gamelistVector.get(i).getOppName());
lastWord.setText(" "+gamelistVector.get(i).getOppLastWord());
diffTime.setText(gamelistVector.get(i).getDiffTime()+"");
score.setText("("+gamelistVector.get(i).getLastMoveScore()+")");
ImageView oppImage = (ImageView) rowView.findViewById(R.id.gl_avatar);
oppImage.setImageBitmap(gamelistVector.get(i).getOppImage());
ImageView status = (ImageView) rowView.findViewById(R.id.gl_status);
status.setImageResource(gamelistVector.get(i).getTurnUserID());
gameListItem.addView(rowView);
}
}
});
}
