ListView selection problem with rating control? - android

friends,
i have created very simple custom listview adapter with ratingBar in it.
now i have noticed one thing i cannot rate those rating bars in listview because
when i click on listview that row particular row gets selected.
any one guide me how to select individual items in android listview?
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ListView
android:layout_width="fill_parent"

android:numStars="10"
android:stepSize="0.1"
android:isIndicator="true"
/>
</LinearLayout>
</LinearLayout>
any help would be appreciated.

Dear UMAR
In order to implement the listeners to the each element to the listview(Single row) use Custom adapter and in the getview(....) method of the custom adapter ,implements the listeners which u want.. sample code `public class FindFriendsListAdapter extends BaseAdapter {
private ArrayList<SingleElementDetails> allElementDetails;
private LayoutInflater mInflater;
private Context context;
private String userid1;
private int usersno1;
private DBAdapter db;
public FindFriendsListAdapter(Context context, ArrayList<SingleElementDetails> results,String userid,int usersno) {
this.context=context;
this.userid1=userid;
this.usersno1=usersno;
allElementDetails = results;
mInflater = LayoutInflater.from(context);
db=new DBAdapter(context);
db.open();
}
public int getCount() {
return allElementDetails.size();
}
public Object getItem(int position) {
return allElementDetails.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(final int position, View convertView, ViewGroup parent)
{
convertView = mInflater.inflate(R.layout.friendlisthelper, null);
ImageView imageview = (ImageView) convertView.findViewById(R.id.friendimageview);
TextView textview = (TextView) convertView.findViewById(R.id.friendtextview);
Button button=(Button)convertView.findViewById(R.id.friendbutton);
convertView.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
//do what u want
}
});
button.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
// do what u want
}
});
return convertView;
}
}
`

android:isIndicator="false" in order to rate it. and listview selection will be gone automatically and control will be transferred to that rating control.

Try this
ListView lv_party;
lv_party.setOnItemClickListener(new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View view, final int position,long id)
{
// TODO Auto-generated method stub
view.findViewById(R.id.btn_del).setOnClickListener(new View.OnClickListener(){
//your code
}

Why is Image OnClickListener() in not responding on click

This is my first try to ask a question. I am a beginner in android.When I am using image OnClickListener() in a simple way it is working but when I use gridView which has one imageView and one TextView on Image Click I want to jump to a new activity.
What I do is just call gridView OnItemClickListener() and jump to another activity which is working as I show below
gridView = (GridView) findViewById(R.id.gridview1);
gridView.setAdapter(new Adapter1(this));
gridView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Intent sendID_intent = new Intent(Activtiy1.this, Activity2.class);
startActivity(sendID_intent);
}
});
wherein Adapter1 I am extends BaseAdapter where an image is load using Picasso library which is also working the only issue is with image click event which is not working properly.
public class Adapter1 extends BaseAdapter {
private Context mC1;
ArrayList<View> viewList = new ArrayList<View>();
public Adapter1(Context context) {
mC1 = context;
}
#Override
public int getCount() {
return normlSearchList.size();
}
#Override
public Object getItem(int position) {
return normlSearchList.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#SuppressLint("ViewHolder")
#Override
public View getView(final int position, View convertView,
ViewGroup parent) {
View view1=convertView;
if ((position + 1) > viewList.size()) {
LayoutInflater inflater = (LayoutInflater) mC1.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view1 = inflater.inflate(R.layout.view_grid,null);
ImageView imageView = (ImageView) view1.findViewById(R.id.iv_galleryb);
TextView textView = (TextView) view1.findViewById(R.id.tv_name);
textView.setText(normlSearchList.get(position).getPost_title());
final String txtID;
String img_url = normlSearchList.get(position).getImage();
Picasso.with(mContext)
.load(img_url)
.placeholder(R.drawable.it_logo_td)
.error(R.drawable.it_logo_td)
.noFade().resize(150, 150)
.centerCrop()
.into(imageView);
viewList.add(view1);
imageView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(mContext, Activity2.class);
mC1.startActivity(intent);
}
});
}
return view1;
}
}
My layout file simply contain relative layout which holds a linearLayout a TextView for display data not found message if no data is found and a gridView
<?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:orientation="vertical"
android:layout_margin="5dp"

<LinearLayout
android:id="#+id/layout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:orientation="horizontal" >
...................
</LinearLayout>
<TextView
android:text=""
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/textView"
android:gravity="center_horizontal"
android:visibility="invisible"
/>
<GridView
android:id="#+id/gridview1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#+id/layout1"
android:numColumns="3"
android:columnWidth="200dp"
android:gravity="center"
android:stretchMode="columnWidth"
/>
My viewgrid.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="100dp"
android:layout_height="80dp"
android:descendantFocusability="afterDescendants">
<ImageView
android:id="#+id/iv_galleryb"
android:layout_width="100dp"
android:layout_height="80dp"
android:clickable="true"
android:scaleType="fitXY"
/>
<TextView
android:id="#+id/tv_name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/iv_galleryb"
/>
I hope I make my problem clear.

I'd avoid use clickable views inside of GridView, instead of, I'd use RecyclerView. Because GridView implements onItemClick, it can conflict with ImageView clickable.
Anyway try add android:focusable="true" in <ImageView />

ListFragment with checkbox onListItemClick never gets called

I've read some SO questions like this and this but still couldn't figure out whats wrong with my code.
I have a ListFragment, and each row has a TextView and a CheckBox.
Clicking the CheckBox is working, but clicking on the TextView does nothing, and OnListItemClick doesn't get called. I've also tried to dynamically add an OnClickListener, which make it work, but it's not the correct way to do it, and it also lacks the GUI feedback of the click (item being "highlighted" for a sec).
This is my textview_with_checkbox.XML I'm using for each item:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:focusable="true"
android:gravity="left"
android:descendantFocusability="blocksDescendants"
android:orientation="horizontal" >
<TextView
android:id="#+id/textview_event_name"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:paddingLeft="3dp"
android:paddingTop="5dp"
android:focusable="true"
android:singleLine="false" />
<CheckBox
android:id="#+id/checkbox_for_event_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.05"
android:focusable="false"
android:clickable="false" />
</LinearLayout>
now the code:
#Override
public void onActivityCreated(Bundle savedInstanceState)
{
super.onActivityCreated(savedInstanceState);
displayEventsLogFiles();
}
#Override
public void onListItemClick(ListView l, View v, int position, long id)
{
super.onListItemClick(l, v, position, id);
String chosenItem = (String) getListAdapter().getItem(position);
mCallBack.onEventItemSelected(chosenItem);
}
static class myCustomAdapterViewHolder
{
public TextView eventName;
public CheckBox eventCheckBox;
}
private class myCustomAdapter extends ArrayAdapter<String>
{
private ArrayList<String> sortedList;
private Context m_oContext;
List<String> m_oValues = null;
public myCustomAdapter(Context cont, int viewResId, List<String> objects)
{
super(cont, viewResId, objects);
m_oContext = cont;
m_oValues = objects;
sortedList = new ArrayList<String>();
for (String str : objects)
sortedList.add(str);
java.util.Collections.sort(sortedList);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View l_oRowView = convertView;
myCustomAdapterViewHolder l_oInitializedViewHolder = null;
final int l_nPosition = position;
// Use convertView if possible, otherwise inflate a view:
if (l_oRowView == null)
{
LayoutInflater inflater = (LayoutInflater) m_oContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
l_oRowView = inflater.inflate(R.layout.textview_with_checkbox, parent, false);
// PlaceHolder pattern:
final myCustomAdapterViewHolder l_oViewHolder = new myCustomAdapterViewHolder();
l_oViewHolder.eventName = (TextView) l_oRowView.findViewById(R.id.textview_event_name);
l_oViewHolder.eventCheckBox = (CheckBox) l_oRowView.findViewById(R.id.checkbox_for_event_name);
l_oViewHolder.eventCheckBox.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
CheckBox cb = (CheckBox)v;
//cb.setChecked(!cb.isChecked());
String l_sFilename = l_oViewHolder.eventName.getText().toString();
if (cb.isChecked())
{
if (!m_lstSelectedFilenames.contains(l_sFilename))
m_lstSelectedFilenames.add(l_sFilename);
}
else
{
if (m_lstSelectedFilenames.contains(l_sFilename))
m_lstSelectedFilenames.remove(l_sFilename);
}
}
});
l_oViewHolder.eventCheckBox.setFocusable(false);
//l_oViewHolder.eventCheckBox.setClickable(false);
// "Add" the viewHolder as a tag:
l_oRowView.setTag(l_oViewHolder);
l_oInitializedViewHolder = l_oViewHolder;
}
else
l_oInitializedViewHolder = (myCustomAdapterViewHolder) l_oRowView.getTag();
// By now, the rowView is initialized, just get the viewHolder and then get the views from it, to update:
//myCustomAdapterViewHolder l_oViewHolder = (myCustomAdapterViewHolder) l_oRowView.getTag();
/*l_oInitializedViewHolder.eventName.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mCallBack.onEventItemSelected((String)getListAdapter().getItem(l_nPosition));
}
});*/
l_oInitializedViewHolder.eventName.setText(m_oValues.get(position));
return l_oRowView;
//return super.getView();
}
public myCustomAdapter(Context cont, int viewResId, String[] strings)
{
this(cont, viewResId, Arrays.asList(strings));
}
#Override
public String getItem(int position)
{
return sortedList.get(position);
}
#Override
public int getPosition(String item)
{
return sortedList.indexOf(item);
}
}
What am I doing wrong here?
All I want is to be able to select "files" for deletion, using the CheckBoxes

Try only using only onclick for textview and checkbox, not onListItemClick -which you can remove- as well, so you should change some properties for the linear layout as well.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:clickable="false"
android:focusable="false"
android:gravity="left"
android:orientation="horizontal" >
<TextView
android:id="#+id/textview_event_name"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:paddingLeft="3dp"
android:paddingTop="5dp"
android:focusable="true"
android:singleLine="false" />
<CheckBox
android:id="#+id/checkbox_for_event_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.05"
android:focusable="false"
android:clickable="false" />
</LinearLayout>
Implement in the adapter
// PlaceHolder pattern:
final myCustomAdapterViewHolder l_oViewHolder = new myCustomAdapterViewHolder();
l_oViewHolder.eventName = (TextView) l_oRowView.findViewById(R.id.textview_event_name);
l_oViewHolder.eventCheckBox = (CheckBox) l_oRowView.findViewById(R.id.checkbox_for_event_name);
l_oViewHolder.eventName.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// your code for textview click
}
}
l_oViewHolder.eventCheckBox.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
CheckBox cb = (CheckBox)v;
//cb.setChecked(!cb.isChecked());
String l_sFilename = l_oViewHolder.eventName.getText().toString();
if (cb.isChecked())
{
if (!m_lstSelectedFilenames.contains(l_sFilename))
m_lstSelectedFilenames.add(l_sFilename);
}
else
{
if (m_lstSelectedFilenames.contains(l_sFilename))
m_lstSelectedFilenames.remove(l_sFilename);
}
}
});
l_oViewHolder.eventCheckBox.setFocusable(false);

add following attribute:
android:focusable="false"
android:clickable="false"
for example in my xml file:
<CheckBox xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#android:id/text1"
android:layout_width="match_parent"
android:layout_height="?android:attr/listPreferredItemHeightSmall"
android:textAppearance="?android:attr/textAppearanceLarge"
android:gravity="center_vertical"
android:button="?android:attr/listChoiceIndicatorSingle"
android:paddingStart="?android:attr/listPreferredItemPaddingStart"
android:paddingEnd="?android:attr/listPreferredItemPaddingEnd"
android:buttonTint="#color/gray"
android:focusable="false"
android:clickable="false"
/>
and in my code:
public class MyTestFragment extends ListFragment {
.....
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
}
}

How to have android longClick event to textView and not in the editText

I try to implement a longClick in the my list view but I get longClick only in the edit text field: how I can get longClick only over the textView?
Thanks, Daniele
Other details:
the main layout is "activity_main.xml" and in the list view "listView_listData" I put the "row.xml" layout with "RigaAdvAdapter" class;
the layout "row.xml" has two field: textView and editText;
I used a ArrayList to store the data that I want to view in the rows (separated by commas - Ex. "viewTextValue,editTextValue");
I need to get longClick in the each row to offer more options;
I dont't need the longClick in the editText otherwise the copy-paste not work;
In the future I'll need more data, and so I'll use an array of ArrayList;

MainActivity
public class MainActivity extends Activity
{
ArrayList<String> arrayDataSource= new ArrayList<String>();
...
I fill the array "arrayDataSource" with a string as "text,another text"
...
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ListView listView_listData =(ListView)findViewById(R.id.listView_listData);
listView_listData.setAdapter(new RigaAdvAdapter());
listView_listData.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener()
{
#Override
public boolean onItemLongClick(AdapterView<?> arg0, View arg1,int pos, long arg3)
{
mostraToast("hh long click"+String.valueOf(pos));
return true;
}
});
}
Adapter class
public class RigaAdvAdapter extends BaseAdapter
{
#Override
public int getCount() {return arrayDataSource.size();}
#Override
public Object getItem(int position) {return position;}
#Override
public long getItemId(int position) {return position;}
#Override

{
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.row, null);
}
TextView textViewField = (TextView)convertView.findViewById(R.id.textViewField);
EditText editTextField = (EditText)convertView.findViewById(R.id.editTextField);
String StringData=arrayDataSource.get(position);
String[] ArrayStringData=StringData.split(",",-1);
String textViewField_val=ArrayStringData[0];
String editTextField_val=ArrayStringData[1];
textViewField.setText(textViewField_val);
editTextField.setText(editTextField_val);
return convertView;
}
}

Instead of setting longclick to ListView you have to set it for TextView.In RigaAdvAdapter class you have to add this
textViewField.setOnLongClickListener(new OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
// TODO Auto-generated method stub
return false;
}
});

Try to set you edittext property set clickable and focusable to false. As you have added Editttext so it will gets the first focus and touch event always.
And to add the Longclick event on TextView you will have to implement the longclick listener inside your adapter class.
#Override
public View getView(int position, View convertView, ViewGroup parent)
{
if (convertView == null)
{
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.row, null);
}
TextView textViewField = (TextView)convertView.findViewById(R.id.textViewField);
EditText editTextField = (EditText)convertView.findViewById(R.id.editTextField);
textViewField.setOnLongClickListener(new OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
// TODO Auto-generated method stub
return false;
}
});
String StringData=arrayDataSource.get(position);
String[] ArrayStringData=StringData.split(",",-1);
String textViewField_val=ArrayStringData[0];
String editTextField_val=ArrayStringData[1];
textViewField.setText(textViewField_val);
editTextField.setText(editTextField_val);
return convertView;
}

You should use onItemLongClickListener inside getView method of the adapter. This question can help Android : How to set onClick event for Button in List item of ListView

Listview listener not getting called

I have button, which on clicked displays a listview and on clicking the listview item it must print something on logcat. I implemented this one in such a way that the list view and its listener are present inside the button onclick listener.
All is working well except the listview listener is not getting called(i.e. nothing is printing on logcat when clicked on listview item)

Remove this code from your onClick() method and implement outside of that onClick() method. Just set Adapter there, but implementation is wrong og onItemClickListener().
lsit.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
System.out.println("hello Android");
}
});

Make sure that in your list_item_layout doesn't have any element is stealing event, like button or TextView with setClickable(true).

android: Custom SimpleCursorAdapter does not load all data

In need of assistance, I have a listview activity which I want to display couple of textfields per item plus 2 buttons (like contacts app having a call button and a text message button. Reading tutorials I found out how to get the buttons to be clickable, but now my textviews (all except 1) don't display any data other then the stock text I've left in the layout file. The 1 text view does display the data I require it to. No where in my custom SCA do I feed it specific data so I'm assuming it happens in the background.
My R.id.company_address_details_phone loads the needed data without any manipulation on my part, but non of the other TextViews in my ViewHolder display any data. My For loop attached to my call button does output data from my cursor so I know it's not that I'm missing data. Any and all help is appreciated.
As a side note, when first wrote the code and did not use a custom SimpleCursorAdapter all my text views populated as expected (i just couldnt click buttons). This leads me to assume that my CompanyActivity class has no errors but that I'm missing something in my CompanyDetailsCursroAdapter class.
*EDIT***
So I'm answering my own question after I looked back and tried something. non of my views where being populated, I just had one of my views set with default text that made it appear as if it was pulled from my DB. I'm now populating my views with data from the cursor adapter passed to my custom cursor adapter using the below code. I would like to know if this is the best way of doing it or is there a more streamlined or android approved method.
