Changing the background of list items by click on a separate button

I have a listView with some items now I want to change the background color or item text color by click on a separate button which IS NOT on the list . How can I do that in my android app?
This is my main activity:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
arrayAdapter = new SubArrayAdapter(this, dataItemList);
ListView lv = findViewById(R.id.mylist);
lv.setAdapter(arrayAdapter);
ImageButton btn_check = findViewById(R.id.button_checkout);
btn_check.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// how can I access the list items within this click-handler method
});
List Item Layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/listitems"
android:layout_width="match_parent"

/>
<ImageView

</LinearLayout>
</android.support.constraint.ConstraintLayout>
And I have myown adapter class that in the getview() method I populated the list items
this inner class is located in mainactivity:
private class SubArrayAdapter extends ArrayAdapter<DataItem> {
private List<DataItem> items;
private Context context;
public SubArrayAdapter(#NonNull Context context, #NonNull List<DataItem>
items) {
super(context, R.layout.listitems, items);
this.items = items;
this.context = context;
}
#NonNull
#Override
public View getView(int position, #Nullable View convertView, #NonNull
ViewGroup parent) {
DataItem dataitem1 = items.get(position);
LayoutInflater inflater = (LayoutInflater)
context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.listitems, null);
TextView tv = (TextView)
view.findViewById(R.id.paragraph_description);
tv.setText(dataitem1.getDescription());
tv.setTag(position + 100);
ImageView yes_iv = view.findViewById(R.id.yes_image);
int yes_res = context.getResources().getIdentifier("yes",
"drawable", getPackageName());
yes_iv.setImageResource(yes_res);
yes_iv.setTag(position + 200);
//yes_iv.setVisibility(View.VISIBLE);
ImageView no_iv = view.findViewById(R.id.no_image);
int no_res = context.getResources().getIdentifier("no", "drawable",
getPackageName());
no_iv.setImageResource(no_res);
no_iv.setTag(position + 300);
return view;
}
}
}

I've noticed You have set android:listSelector for ListView in Your activity_main.xml - which was giving You an ability to change item's background on single click.
So I decided to check out how it works in ListView class.
I've looked at source code of ListView and searched for phrase selector. There was the line:
} else if (mAction == STATE_REQUEST_FOCUS) {
final int childIndex = mPosition - mFirstPosition;
final View child = getChildAt(childIndex);
if (child != null) {
child.requestFocus();
}
mAction = -1;
}
final View child = getChildAt(childIndex);
Following these steps - I knew solution for Your question problem. Here it is:
ImageButton imageButton = findViewById(R.id.button_checkout);
imageButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int hardCodedPoositionToSelect = 1;
View childAt = listView.getChildAt(hardCodedPoositionToSelect);
if (childAt != null) {
//change background
childAt.setBackgroundColor(Color.RED);
//change textView color of current view
TextView paragraphDescription = childAt.findViewById(R.id.paragraph_description);
paragraphDescription.setTextColor(Color.MAGENTA);
}
}
});
You can see I am calling getChildAt() on listView to obtain current item's view basing on item's position from hardCodedPoositionToSelect.

How give number to listview items in android

I am new to android . I have an application working with listview and i want to number each list view item.
Like,
1 list item
2 list item
3 list item

i want to set numbering in tvSlNo.
please help

In your getView() method of your listViewAdapter simply use the position variable and set it on your TextView. You may need to add 1 to the position since it starts with 0. So use (position+1) and then set it to your TextView

Though this question may be too late but for other reference purposes.
Check where you have this code: txt.setText(position + 1);
you are close to your solution. You just have to typecast position + 1 to String since setText() only take String alone.

Custom list view with dynamic list items Android

I want to implement a custom list view with the number of list items entered in a text view by the user.
Can anyone help me? I have no idea about how to do that. i found a code that add items on click how can i modify that to match my requirements

First You need to make a layout for each item of listView name it as custom_listview_item
<?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="wrap_content">
<RelativeLayout
android:layout_width="150dp"
android:layout_height="150dp">
<TextView
android:id="#+id/lst_label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="18sp"/>
<ImageView
android:id="#+id/lst_image"
android:layout_width="150dp"
android:layout_height="150dp"
android:src="#drawable/start"
android:layout_centerInParent="true" />
</RelativeLayout>
</LinearLayout>
then in your MainActivity add this
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
context=this;
lv=(ListView) findViewById(R.id.listView);
lv.setAdapter(new CustomAdapter(this, R,Layout.custom_listview_item,prgmImages));
}
class CustomAdapter extends ArrayAdapter {
public CustomAdapter(Context context, int resource, Integer[] objects) {
super(context, resource, objects);
}
public View getView(final int position, View convertView, ViewGroup parent) {
convertView = ((Activity) getContext()).getLayoutInflater().inflate(R.layout.custom_listview_item, null);
ImageView img = (ImageView) convertView.findViewById(R.id.lst_image);
TextView tv = (TextView) convertView.findViewById(R.id.lst_label);
img.setImageResource((prgmImages[position]));
tv.setText(prgmNameList[position]));
return convertView;
}
}

ListView updated from EditText

I have a Custom Listview that it is updated from a EditText component in a dialog. I have the custom row, the adapter class and the custom dialog all working but I can't seem to trigger the code in the adatper class that would add the text from the edit text control to the list. Here is my activity code, let me know if you want the adapter code. It worked before I added the custom row and adapter to the list :(
Symptom of problem: emailAdapter.notifyDataSetChanged(); does nothing
public class InvitePlayers_Activity extends Activity {
ListViewAdapter emailAdapter = null;
ImageView imgView_mail;
ImageView imgView_confirm;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE); //remove title bar
setContentView(R.layout.activity_inviteplayers);
//Generate list View from ArrayList
displayListView();
}
private void displayListView() {
//assign controls
final ListView listView = (ListView) findViewById(R.id.listView_invitePlayers);
imgView_mail = (ImageView)findViewById(R.id.imgView_mail);
//Test data
ArrayList<String> inviteNew = new ArrayList<String>();
final ArrayList<ArrayList<String>> inviteList = new ArrayList<ArrayList<String>>();
emailAdapter = new ListViewAdapter(this,inviteList);
listView.setAdapter(emailAdapter);
// Assign adapter to ListView
listView.setTextFilterEnabled(true);
//Edit listeners
imgView_mail.setOnClickListener(new View.OnClickListener() {
public void onClick(View view)
{
//variables
final String enteredMail = "testListViewEntry";
final ArrayList<ArrayList<String>> inviteList = new ArrayList<ArrayList<String>>();
ArrayList<String> invite = new ArrayList<String>();
invite.add(0, enteredMail);//add first email
invite.add(1,"icon_invitestatussent.png"); //add first status icon
inviteList.add(invite);
emailAdapter.notifyDataSetChanged();
listView.setAdapter(emailAdapter);
}
});
}
}
Adapter code as requested
public class ListViewAdapter extends BaseAdapter {
private Activity context;
ArrayList<ArrayList<String>> inviteDetails = new ArrayList<ArrayList<String>>();
public ListViewAdapter(Activity context, ArrayList<ArrayList<String>> inviteDetails ) {
this.inviteDetails = inviteDetails;
this.context = context;
}
#Override
public int getCount() {
return inviteDetails.size();
}
#Override
public Object getItem(int i) {
return inviteDetails.get(i).get(0);
}
#Override
public long getItemId(int i) {
return i;
}
public View getView(int position, View view, ViewGroup parent){
//Inflater
LayoutInflater inflater = context.getLayoutInflater();
//get row view
if (view == null) {
LayoutInflater mInflater = (LayoutInflater)
context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
view = mInflater.inflate(R.layout.list_item_email, null);
}
//assign controls
final TextView textView_playerEmail = (TextView) view.findViewById(R.id.textView_playerEmail);
ImageView imgView_inviteStatus = (ImageView) view.findViewById(R.id.imgView_inviteStatus);
//Assign control values that are dynamic
textView_playerEmail.setText(inviteDetails.get(position).get(0));
imgView_inviteStatus.setImageResource(R.drawable.icon_invitestatussent);
return view;
}
#Override
public void notifyDataSetChanged() {
super.notifyDataSetChanged();
}
}

Well, for what we discussed, you wanted something like this:
When you want to make a custom ListView, you have to write your own adapter. In this particular case I'm subclassing the BaseAdapter class.
This custom adapter will take hold of my data model, and will inflate the data to my ListView rows.
First, I'll create the XML of my custom row. You can see the code below.
item_mail.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="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Test text"
android:id="#+id/tv_mail"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_centerVertical="true"/>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/iv_icon"
android:layout_alignParentTop="true"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:src="#android:drawable/ic_menu_report_image" />
</RelativeLayout>
Here I've created a row that displays a text and an image.
Now, I'll create my custom adapter to handle this XML. As you can see below.
MailAdapter.java
public class MailAdapter extends BaseAdapter {
private static final String LOG_TAG = MailAdapter.class.getSimpleName();
private Context context_;
private ArrayList<ArrayList<String>> mailitems;
public MailAdapter(Context context, ArrayList<ArrayList<String>> mailitems) {
this.context_ = context;
this.mailitems = mailitems;
}
#Override
public int getCount() {
return mailitems.size();
}
#Override
public Object getItem(int position) {
return mailitems.get(position).get(0);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater mInflater = (LayoutInflater)
context_.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.item_mail, null);
}
TextView tv_mail = (TextView) convertView.findViewById(R.id.tv_mail);
ImageView iv_icon = (ImageView) convertView.findViewById(R.id.iv_icon);
String mail = mailitems.get(position).get(0);
String icon = mailitems.get(position).get(1);
Log.d(LOG_TAG,"Mail: " + mail + " mail_icon: " + icon);
tv_mail.setText(mail);
// iv_icon.setImageURI(); Here you can do whatever logic you want to update your image, using URI's, ID's, or something else.
return convertView;
}
}
Ok. Now we have everything to make this work. In your Activity class, do something like that:
activity_main.xml
<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" android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin" tools:context=".MainActivity">
<TextView
android:text="#string/hello_world"
android:id="#+id/tv_header"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/tv_header">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Add mail"
android:id="#+id/button"
android:layout_gravity="center" />
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/listView" />
</LinearLayout>
</RelativeLayout>
MainActivity.java
public class MainActivity extends ActionBarActivity {
private int numMail = 1; // Dummy int to create my items with different numbers.
private MailAdapter mailAdapter; // Your custom adapter.
private ArrayList<ArrayList<String>> mailItems; // This is going to be your data structure, everytime you change it, call the notifyDataSetChanged() method.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button bt = (Button) findViewById(R.id.button);
ListView lv_mail = (ListView) findViewById(R.id.listView);
mailItems = new ArrayList<>();
mailAdapter = new MailAdapter(this,mailItems);
lv_mail.setAdapter(mailAdapter);
bt.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
addItem(); // The method I'm using to insert the item. Look for it below.
}
});
}
// Here I'm creating a new ArrayList, and appending it to my 'mailItems' Array. After that, I'm notifying the adapter that my data changed.
private void addItem() {
ArrayList<String> mail = new ArrayList<>();
mail.add(0,"mail " + numMail++);
mail.add(1,"path_to_image"); // Depending on what you want to do, put your path, URI, or whatever other way you want to store that image data.
mailItems.add(mail); // Inserting the data on the ArrayList.
mailAdapter.notifyDataSetChanged(); // Notifying the adapter that my ArrayList was modified.
}
}
This should do the trick.
I guess your problem was that you weren't updating the same ArrayList that was in your custom adapter. That's why when you called notifyDataSetChanged()nothing happened, I mean. You were creating a new ArrayList, which wasn't the same that was in your adapter. So here's what I did... I've made the ArrayList global, and then I've used it in my custom adapter constructor. After that, when the user triggers the onClick() method of my button, I'm inserting some new data on my global Array, and then I'm notifying the adapter that the data changed.
You can read a little more about that here and I've found a similar question here, which you can read as well.
Edit: Another related question, which might be an interesting read.

Android custom adapter and ListView shows nothing

I want to create a ListView populated by my own layout and my data. So I looked at examples and I found that I need to extend ArrayAdapter<>.
So I made a CustomAdapter and did everything by following an example.
There is no error in the code but the ListView #id/dashboard doesn't appear in my MainActivity.
I can see the TextView from activity_main.xml but not the ListView.
The sliding menu of the DrawerLayout is working too.
I inflate overview.xml in my CustomAdapter.
Can you give me an hint why it's not working? I'm working on it for hours.
Thank's
CustomAdapter
public class CustomAdapter extends ArrayAdapter<Ssoverview> {
private int layoutId;
private Context context;
private ArrayList<Ssoverview> list;
public CustomAdapter(Context context, int resource, ArrayList<Ssoverview> ssList) {
super(context, resource);
this.layoutId = resource;
this.context = context;
this.list = ssList;
}
#Override
public View getView(int position, View convertView, ViewGroup parent){
View v = convertView;
if (v == null) {
v = (RelativeLayout) ((Activity)context).getLayoutInflater().inflate(this.layoutId, null); //, parent, false);
}
Ssoverview ss = this.list.get(position);
if (ss != null) {
TextView titleTV=(TextView) v.findViewById(R.id.title);
titleTV.setText(ss.getTitle());
TextView authorTV=(TextView) v.findViewById(R.id.author);
authorTV.setText(ss.getAuthor());
}
Log.d("Deb", "Fabrication de la View : "+position);
return v;
}
}
activity_main.xml :

change
public CustomAdapter(Context context, int resource, ArrayList<Ssoverview> ssList) {
super(context, resource);
this.layoutId = resource;
this.context = context;
this.list = ssList;
}
to
public CustomAdapter(Context context, int resource, ArrayList<Ssoverview> ssList) {
super(context, resource , ssList); <-- change this line
this.layoutId = resource;
this.context = context;
this.list = ssList;
}
in arrayAdapter class super in constructor handle size of your list, as you don't pass your data this set to 0 in default so getView not called at all
