Everything shows inside the dialog except the listview - android

I'm trying to have an edittext with a list view to choose contacts from a custom listview here is the code but everything appears except the listview:

public class InstantTextBoxDialog extends DialogFragment {
private EditText message;

listContacts=(ListView)view.findViewById(R.id.list_checkable);
ChackableListAdapter adapter=new ChackableListAdapter(getActivity(),R.layout.list_chackable_item,new ArrayList<Contact>());
sendToAll.setOnClickListener(new View.OnClickListener() {
#Override

if(!TextUtils.isEmpty(message.getText())){
ChatService.bind.getService().sendMessageToAll(message.getText().toString());
message.setText("");
dismiss();
}
}
});
sendToLimited=(Button) view.findViewById(R.id.btn_send_to_limited);
sendToLimited.setOnClickListener(new View.OnClickListener() {
#Override

});
listContacts.setAdapter(adapter);
builder.setView(view);
return builder.create();
}

The dialog box is trigered from an adapter of a listview and that's the adapter's code:
holder.replay.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
InstantTextBoxDialog exampleDialog=new InstantTextBoxDialog();
exampleDialog.show(((Activity) activity).getFragmentManager(),"sadsdadsaadassd");
}
});
But till now nothing shows except the buttons and no listview

How to add items to recyclerview programmatically? [duplicate]

I have a button(save contact) to save contacts ,the button when pressed get name and email from edit text and should dynamically add 1 list item in recycle view
The save button is in fragment
This is the name which i am extracting

When i click on lead it should add in the existing recycleview
leads.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
newValueAdapter.newAddeddata(company_name.getText().toString());*/
}
});
The recycle view already have a arraylist,how do i add new value to the arraylist and again call oncreate
I tried to extract company name and send it to the adapter of that recycler view but it dint work

Add this method to your adapter and call on button click.
public void newAddeddata(String company_name){
NewleadsPOJO newValue=new NewleadsPOJO();
newValue.setLeads_company(company_name);
datalist.add(newValue);
notifyDataSetChanged();
}
Add following method to NewLeadFrag
public NewleadsAdapter getAdapter(){
return adapter;
}
now in Createmeetingfrag
leads.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
NewLeadFrag fragment = getFragmentManager().findFragmentByTag("NewLeadFrag_TAG"); //set tag of fragment when you add with fragment manager. and if you are using support library use getSupportFragmentManager()
if(fragment!= null){
fragment.getAdapter().newAddeddata(company_name.getText().toString());
}
}
});

You don't need to go through the entire life cycle of your Activity or Fragment just because you've made changes to the list. Instead try adding the item in the list you currently have associated with the Adapter. And then call adapter.notifyDataSetChange(). This should automatically add the new Item to the RecyclerView.

Android recyclerView Adapter Popup menu not working

I'm trying to make a notes app and I already got the items (notes) to be listed in the recycler. There is an ImageButton on each of the items and I want a popUpMenu to appear once it is clicked.
It is possible to click the imageButton for individual items but I cant get the popUpMenu to appear for each individual item.
If there is a better or alternative way that would be great too.

You need to create some /res/menu/popupmenu.xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:title="Menu Item" />
</menu>
Then, below your line PopupMenu popupMenu = new PopupMenu(context,holder.optionBtn); you need to inflate the menu with popupMenu.inflate(R.menu.popupmenu);

You must replace only the
holder.optionBtn with view
PopupMenu popupMenu = new PopupMenu(context,view);
And your code is start working.

Android - SetOnItemClickListener doesn't work

I know here we have a lot of questions like mine, but I don't know why none works for me.
My objective: I have an AlertDialog with a ListView with a check box in each row, I can select some of the items, and I wish to make an ArrayList with the elements selected.
For that reason, I'm calling the SetOnclickListener, I put a Log inside the method, but does nothing.
I tried with focusable and clickable almost everywhere, but my Log doesn't appear.
Here My alert Dialog
private void callAdditionalDialog() {
LayoutInflater layoutInflater = LayoutInflater.from(ConfigProductActivity.this);
final View additionalView = layoutInflater.inflate(R.layout.dialog_additional, null);
additionalView.setFocusable(true);
// set the custom dialog components - text, buttons, accountants
TextView titleDialog = (TextView) additionalView.findViewById(R.id.title_additional);
titleDialog.setTypeface(boldFont);
Button buttonAccept = (Button) additionalView.findViewById(R.id.button_accept);
buttonAccept.setTypeface(boldFont);
Button buttonCancel = (Button) additionalView.findViewById(R.id.button_cancel);
buttonCancel.setTypeface(boldFont);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(ConfigProductActivity.this);
alertDialogBuilder.setView(additionalView);
final AlertDialog alertD = alertDialogBuilder.create();
alertD.setCanceledOnTouchOutside(false);
//Fill object of additional
final ListView additionalListView = (ListView) additionalView.findViewById(R.id.list_additional);
TextView additionalNotFound = (TextView) additionalView.findViewById(R.id.additional_not_found);
if (!withoutModifiers){
additionalAdapter = new AdditionalAdapter(ConfigProductActivity.this, additionalList);
additionalListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
additionalListView.setAdapter(additionalAdapter);
final ArrayList<ModifierEntity> modifierList = new ArrayList<ModifierEntity>();
additionalListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent,
View view, int position, long id) {
Object modifier = additionalListView.getAdapter().getItem(position).toString();
Log.d(TAG, "SOMETHIIIIING");
}
});
}
else{
additionalListView.setVisibility(View.GONE);
additionalNotFound.setVisibility(View.VISIBLE);
additionalNotFound.setTypeface(font);
buttonCancel.setVisibility(View.GONE);
}
//End of fill object of additional
buttonCancel.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
additionalBox.setEnabled(true);
alertD.dismiss();
}
});
buttonAccept.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//additional.setText(additionalAdapter.getCount());
additionalBox.setEnabled(true);
alertD.dismiss();
}
});
alertD.show();
}
Here my adapter:
public class AdditionalAdapter extends ArrayAdapter {
private static String TAG = AdditionalAdapter.class.getName();
private List<ModifierEntity> originalData = null;
private ConfigProductActivity activity;
private Typeface font;
private Typeface boldFont;
private static ModifierEntity modifier;
public AdditionalAdapter (ConfigProductActivity activity, List<ModifierEntity> listArray){
super(activity, R.layout.additional_item);
this.activity = activity;
this.originalData = listArray ;
font = Typeface.createFromAsset(activity.getAssets(),"HelveticaNeueThn.ttf");
boldFont = Typeface.createFromAsset(activity.getAssets(), "avgardm.ttf");
}
public static class Row
{
public TextView labelName;
public TextView labelPrice;
public CheckBox check;
}
#Override
public int getCount() {
return originalData.size();
}
#Override
public ModifierEntity getItem(int position) {
return originalData.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
final int colorFont = activity.getResources().getColor(R.color.brown_tataki);
final Row holder;
View rowView = convertView;
// reuse views
if (convertView == null) {
holder = new Row();
LayoutInflater inflater = LayoutInflater.from(activity);
rowView = inflater.inflate(R.layout.additional_item, null);
rowView.setClickable(true);
//rowView.setFocusable(false);
// configure view holder
holder.labelName = (TextView) rowView.findViewById(R.id.additional_name);
holder.labelPrice = (TextView) rowView.findViewById(R.id.additional_price);
holder.check = (CheckBox) rowView.findViewById(R.id.additional_check);
rowView.setTag(holder);
}
else {
holder = (Row) convertView.getTag();
// rowView.setClickable(true);
}
final ModifierEntity itm = originalData.get(position);
holder.labelName.setText(itm.getModifier_name());
holder.labelName.setTypeface(font);
holder.labelName.setTextColor(colorFont);
holder.labelPrice.setText(GlobalParameters.CURRENCY.concat(String.valueOf(itm.getModifier_cost())));
holder.labelPrice.setTypeface(boldFont);
holder.labelPrice.setTextColor(colorFont);
return rowView;
}
}

Using interfaces I can solve my problem, this link provided me the solution, and bassically consist in create an interface and implement in my activity.
Like this:
1.- Interface
public interface MyListener {
void folderClicked();
}
2.- Implements the interface in the activity
public class ActivityA extends Activity implements MyListener
3.- You will have to auto override the method folderClicked it will look like this:
#Override
protected void folderClicked() {
// Do your stuff here.
}
4.- Send the activity listener to the adapter with constructor like this:
MyAdpater adapter = new MyAdpater(ActivityA.this);
5.- Your adapter class your code should be like this:
public class TimeLineAdapter extends BaseAdapter {
private MyListener mListener;
public TimeLineAdapter(MyListener listener) {
super();
mListener = listener;
}
holder.iconImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mListener.onFolderClicked()
//code to do stuff when the image is clicked
}

Check all checkboxes in custom list view

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>();

sortedList.add(str);
java.util.Collections.sort(sortedList);
}
#Override

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

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.setOnClickListener(new View.OnClickListener() {
#Override

//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"
