I'm looking for a way to implement a dialog which asks for confirmation when clicking on the delete button of my ListView row. I tried to do it inside my custom ArrayAdapter, but as it is no Activity I don't know how to do it.
When I put the whole onClick-Listener inside the MainActivity, I have no clou how to find out which position the button was clicked so that I can remove it afterwards.
public class ServiceAdapter extends ArrayAdapter<Service> {
private final Singleton singleton = Singleton.getInstance();
private ArrayList<Service> services;
public ServiceAdapter(Context context, ArrayList<Service> services) {
super(context, 0, services);
this.services = services;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// Get the data item for this position
Service service = getItem(position);
// Check if an existing view is being reused, otherwise inflate the view
if (convertView == null) {
convertView = LayoutInflater.from(getContext()).inflate(
R.layout.listview_row, parent, false);
}
// Lookup view for data population
TextView quantity = (TextView) convertView
.findViewById(R.id.QUANTITY_CELL);
TextView description = (TextView) convertView
.findViewById(R.id.DESCRIPTION_CELL);
Button delete = (Button) convertView.findViewById(R.id.BUTTON_DELETE);
// Populate the data into the template view using the data object
quantity.setText(String.valueOf(service.getQuantity()));
description.setText(service.getDescription());
// Set up the listener for the delete button.
final View view = convertView;
view.setTag(Integer.valueOf(position));
delete.setOnClickListener(new Button.OnClickListener() {
#Override
public void onClick(View v) {
Integer index = (Integer) view.getTag();
services.remove(index.intValue());
notifyDataSetChanged();
}
});
// Return the completed view to render on screen
return convertView;
}
}
public class MainActivity extends Activity {
private ListView serviceList;
private ArrayList<Service> services;
private ServiceAdapter adapter;
private final Singleton singleton = Singleton.getInstance();
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
serviceList = (ListView) findViewById(R.id.service_list);
adapter = new ServiceAdapter(this, services);
serviceList.setAdapter(adapter);
serviceList.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
final int position, long id) {
Service temp = services.get(position);
singleton.setQuantity(temp.getQuantity());
singleton.setDescription(temp.getDescription());
setPosition(position);
openDetailedEntry();
}
});
}
public void openDetailedEntry() {
Intent i = new Intent(this, DetailedEntryActivity.class);
// Check if the meant Activity is actually resolvable
if (i.resolveActivity(getPackageManager()) != null)
startActivity(i);

Let me know if you need something.
Construct AlertDialog in ServiceAdapter Like this,
private AlertDialog mDialog;
private int mListRowPosition;
public ServiceAdapter(Context context, ArrayList<Service> services) {
super(context, 0, services);
this.services = services;
//Create AlertDialog here
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setMessage("Your Message")
.setPositiveButton(R.string.fire, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// Use mListRowPosition for clicked list row...
}
})
.setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// User cancelled the dialog
}
});
// Create the AlertDialog object
mDialog = builder.create();
}
Create method in ServiceAdapter Like,
private void showDialog(int position)
{
mListRowPosition = position;
if(mDialog != null)
mDialog.show();
}
Now in onClick() Just call
showDialog(position); // But make position of getView() as final...

There is issue of views getting in conflict i.e. views might be getting over lapped by others so add
android:descendantFocusability="blocksDescendants" on your parent layout and list item and for all views for which you want to handle click events, for them, android:focusable="false" add this as well like here in button...
TRY this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:descendantFocusability="blocksDescendants"
android:layout_width="match_parent"
android:layout_height="match_parent">
Step 1: In list_item.xml, add android:descendantFocusability="blocksDescendants" to your root Linearlayout.
Step 2: In list_item.xml, add android: focusable="false" to android.support.v7.widget.CardView
Note: If there is android:clickable="true" in android.support.v7.widget.CardView remove it.
Basically I have listview in my fragment layout. And another layout called item_todo.xml which contains my button.

You inflate a new View in your onActivityCreated But you never used that view !!! myButton refer to a button which its view has not been used !
Edit :
There are lots of ways you can reach your goal:
Interfaces
You can initialize an interface and pass it to fragment, so whenever something happen in your activity (button click for example), you will understand
BroadcastReceivers
You can register local broadcast receivers in your fragment and when user click on the button, you send that broadcast, so fragment will understand
i suggest the second one and using EVENTBUS library
Well, I try to explain.
I made an application where I have a listview where each row have also two buttons (I have made it with other question posted in this site).
The problem is this:
The two buttons is "start" and "stop". When I click start, a service starts and when I click on stop this service has to stop (I haven't implemented the service for now).
So, when I click start, I would like to hide the start button, in this way I know that the service is started.
How can I do it? Besides, it can be the right choice implements the service in this way?
I have choosen this idea because I need to stop the service when I decide to stop it.
Code:
MainActivity.java
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//generate list
ArrayList<String> list = new ArrayList<String>();
list.add("item1");
list.add("item2");
//instantiate custom adapter
android.widget.ListAdapter adapter = new ListAdapter(this,0,list);
//handle listview and assign adapter
ListView lView = (ListView)findViewById(R.id.list_item);
lView.setAdapter(adapter);
}
}

ListAdapter.java
public class ListAdapter extends ArrayAdapter<String> {
private ArrayList<String> list;
private int layout;
private Context context;
public ListAdapter(Context context, int resource, ArrayList<String> objects) {
super(context, resource, objects);
context = context;
layout = resource;
list = objects;
}
public View getView(final int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null) {
LayoutInflater inflater = LayoutInflater.from(getContext());
view = inflater.inflate(R.layout.row_item, null);
}
//Handle TextView and display string from your list
TextView listItemText = (TextView)view.findViewById(R.id.list_item_string);
listItemText.setText(list.get(position));
//Handle buttons and add onClickListeners
Button deleteBtn = (Button)view.findViewById(R.id.stop_button);
Button addBtn = (Button)view.findViewById(R.id.start_button);
deleteBtn.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
Toast.makeText(getContext(), "delete - Button was clicked for list item " + position, Toast.LENGTH_SHORT).show();
//do something
notifyDataSetChanged();
}
});
addBtn.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
Toast.makeText(getContext(), "start - Button was clicked for list item " + position, Toast.LENGTH_SHORT).show();
notifyDataSetChanged();
}
});
return view;
}
}
you can use some boolean flag value to change the visibility of button on click.
addBtn.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
Toast.makeText(getContext(), "start - Button was clicked for list item " + position, Toast.LENGTH_SHORT).show();
//do something
addBtn.setVisibility(View.GONE);
notifyDataSetChanged();
}
});
deleteBtn.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
Toast.makeText(getContext(), "delete - Button was clicked for list item " + position, Toast.LENGTH_SHORT).show();
//do something
addBtn.setVisibility(View.VISIBLE);
notifyDataSetChanged();
}
});
In this way seems working
If on your list you have more than one element, then you have to implement a custom adapter and create an ad hoc listner for each element. Use setTag and getTag.
CHange row_item.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:text="Text"
android:id="#+id/list_item_string"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="5pt"
android:layout_marginTop="2pt"
android:textSize="10pt"
android:layout_weight="0.49"/>
<Button
android:text="Start"
android:id="#+id/start_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="start"/>
<Button
android:text="Stop"
android:id="#+id/stop_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toEndOf="#+id/start_button"
android:onClick="stop"
android:layout_marginLeft="10dp"
android:layout_toRightOf="#+id/start_button" />
</LinearLayout>
And in MainAcitivty
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//generate list
ArrayList<String> list = new ArrayList<String>();
list.add("item1");
list.add("item2");
//instantiate custom adapter
ListAdapter adapter = new ListAdapter(this, 0, list);
//handle listview and assign adapter
ListView lView = (ListView)findViewById(R.id.list_item);
lView.setAdapter(adapter);
}
public void start(View v){
Button b = (Button) v;
v.setVisibility(View.INVISIBLE);
}
public void stop(View v){
}
}
ListAdapter
public View getView(final int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null) {
LayoutInflater inflater = LayoutInflater.from(getContext());
view = inflater.inflate(R.layout.row_item, null);
}
//Handle TextView and display string from your list
TextView listItemText = (TextView)view.findViewById(R.id.list_item_string);
listItemText.setText(list.get(position));
//Handle buttons and add onClickListeners
Button deleteBtn = (Button)view.findViewById(R.id.stop_button);
Button addBtn = (Button)view.findViewById(R.id.start_button);
return view;
}
You need to use the setVisible(false) method
Example:
addBtn.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
Toast.makeText(getContext(), "start - Button was clicked for list item " + position, Toast.LENGTH_SHORT).show();
notifyDataSetChanged();
addBtn.setVisible(false); // ← Hide the "Start button"
}
});
To Hide start Button after clicking,
addBtn.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
Toast.makeText(getContext(), "start - Button was clicked for list item " + position, Toast.LENGTH_SHORT).show();
notifyDataSetChanged();
addBtn.setVisibility(View.GONE);
}
});
I have search a lot of questions here and already implemented every answer i get from here, but no one has solved this problem. I have 2 buttons in a row of my custom listview and i want to perform on click on them. Here is my custom adapter and xml code.

Can anyone tell me where did i make mistake? My work is about to finish and app is almost ready but i am stuck in this problem. I will be thankfull to any type of suggestion or help.
I am not sure,but Try holder.edit.setOnClickListener(new View.OnClickListener())
instead of holder.edit.setOnClickListener(new OnClickListener()).
try this
add this cartlist_row.xml in parent Linearlayout
android:clickable="false"
android:descendantFocusability="blocksDescendants"
android:focusable="false"
android:focusableInTouchMode="false"
for Button add this
android:clickable="false"
android:focusable="false"
android:focusableInTouchMode="false"
and AlertDialog.Builder builder is not working , you never used show().. Please Cross check .. Use
AlertDialog alert = builder.create(); alert.show();

When you click the button a toast message with list of item choosen is displayed. You can modify the above according to your requirements.
Set selection mode on your ListView
//if using ListActivity or ListFragment
getListView().setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
//or
myListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
//myListView is reference to your ListView
1.Make visibility gone to you tick mark image
2.Implement view.setOnClickListener in arrayadapter.
3.In that check image.getVisibility()==View.GONE then make image.setVisibity(View.Visible)
4.if image.getVisiblity()==View.VISIBLE then make your image.setVisibity(View.GONE)
Try this.
