How to select two list items at same time ? To be specific ONLY TWO items not more than that

I have a list view like the below image.
Now I want to select Only Any two items from the list view at a time and pass the values of both listview items with Intent to next activity. How can I achieve it.?
If Both items are not selected set validation on it?

I would use Action Mode with MultiChoiceModeListener.
http://developer.android.com/reference/android/widget/AbsListView.MultiChoiceModeListener.html
There is a callback onItemCheckedStateChanged(ActionMode mode, int position, boolean checked).
You can easily get values of already checked list items ListView.getCheckedItemPositions. So you can prevent selection, if you already selected two or even at once pass the values(or ids) of selected ones without any effort.

You can simply put a counter on item selection.
Take a variable say for ex.
int count = 0;
Check this variable before marking item as selected/deselected:
if(item.isSelected())
{
// you need to make is disable
if(count>0)
{
count--;
// // mark item as deselected
}
}
else
{
// make it selected
if(count<2)
{
count++;
// mark item as selected
}
}
This will make you select ONLY TWO items at a time.
Modify your adapter like this:
public class LoadAdapter extends BaseAdapter {
private ArrayList<DataBase> mProductItems;
private LayoutInflater mLayoutInflater;
private Context mContext;
DBHelper mydb;
DataBase stringItem;
ArrayList<Boolean> selected = new ArrayList<>();
private int count=0;
public LoadAdapter(Context context, ArrayList<DataBase> arrayList){
mContext = context;
mProductItems = arrayList;
mLayoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
for (int i = 0; i < arrayList.size(); i++) {
selected.add(false);
}
}
#Override
public int getCount() {
// TODO Auto-generated method stub
Log.e("testtt", String.valueOf(mProductItems.size()));
return mProductItems.size();
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return null;
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
final ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = mLayoutInflater.inflate(R.layout.load_chart_item, parent, false);
holder.txtv_name = (TextView) convertView.findViewById(R.id.text);
holder.nameid = (TextView) convertView.findViewById(R.id.nameid);
holder.btn_delete = (Button) convertView.findViewById(R.id.btn_delete);
holder.btn_edit = (Button)convertView.findViewById(R.id.btn_edit);
holder.location = (TextView)convertView.findViewById(R.id.loc);
holder.btn_delete.setTag(position);
convertView.setTag(holder);
} else {
holder = (ViewHolder)convertView.getTag();
}
mydb = new DBHelper(mContext);
stringItem = mProductItems.get(position);
if (stringItem != null) {
if (holder.txtv_name != null) {
holder.txtv_name.setText(stringItem.getName());
holder.nameid.setText(stringItem.getId());
holder.location.setText(stringItem.getLocation());
Log.e("saved Location values",stringItem.getLocation());
}
}
if(selected.get(position))
{
//for selected row
holder.txtv_name.setTextColor(color.red);
}
else
{
// for not selected row
holder.txtv_name.setTextColor(color.black);
}
holder.txtv_name.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(holder.txtv_name.getCurrentTextColor()== R.color.black)
{
//is not selected
if(count<2)
{
count++;
selected.set(position,true);
// mark item as selected
}
}
else
{
//is selected
if(count>0)
{
count--;
selected.set(position,false);
// // mark item as deselected
}
}
notifyDataSetChanged();
}
});
holder.btn_delete.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
DataBase test = mProductItems.get(position);
String id = test.getId();
mydb.deleteContact(Integer.valueOf(id));
mProductItems.remove(mProductItems.get(position));
LoadAdapter.this.notifyDataSetChanged();
if (mProductItems.size() == 0){
mProductItems.clear();
LoadAdapter.this.notifyDataSetChanged();
}
}
});
Log.e("DataBase", String.valueOf(mydb.getAllCotacts()));
holder.btn_edit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent=new Intent(mContext,UpdateData.class).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
SharedPreferences preff = PreferenceManager.getDefaultSharedPreferences(mContext);
SharedPreferences.Editor edi = preff.edit();
edi.putString("key",String.valueOf(position+1));
edi.apply();
mContext.startActivity(intent);
}
});
return convertView;
}
public void refresh(ArrayList<DataBase> items)
{
this.mProductItems = items;
notifyDataSetChanged();
}
private static class ViewHolder {
TextView txtv_name,nameid,location;
Button btn_delete,btn_edit;
}}
EDIT 2: For getting selected items from adapter define below method in
adapter and call it with an adapter object like : adp.getSelected()
public String getSelected() {
String selectedString = "";
int num=0;
for (int i = 0; i < selected.size(); i++) {
if (selected.get(i)) {
num++;
if (num == 1) {
selectedString = mProductItems.get(i).getName();
} else {
selectedString += "," + mProductItems.get(i).getName();
}
}
}
return selectedString;
}
Answer to issue 2 : If you want to use ImageView instead of text color change. The do the same things as above but replace the TextView + Color with ImageView + Image.
EDIT 3:
You have called the getSelected() method from a Null object. Modify your code like this:
listView = (SwipeListView) findViewById(R.id.listview);
loadAdapter = new LoadAdapter(getApplicationContext(),array_list);
listView.setAdapter(loadAdapter);
det.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String str = "";
str = loadAdapter.getSelected();
Toast.makeText(RelationShipChartList.this, str, Toast.LENGTH_SHORT).show();
}

Custom listview in Textview Value change by Scrolling

This Is my Adapter problem was scroll listview to change textview value by every position how to solve it ? plus click event to increment one and minus event to decrment and set value in textview (Plus click to quantity + 1 , minus click to quantity - 1).

how to make input search for custom list view

hello to every one i have a custom list view with a search and animation all works cool but in search i have a little problem . I would like to, for example, I search for a word in a sentence.
But the way I used to enter the letters i have to put them in sequence.
here is my code:
public class MainActivity extends Activity {
ListView list;
ListViewAdapter adapter;
EditText editsearch;
String[] country;
Typeface tf;
ArrayList<WorldPopulation> arraylist = new ArrayList<WorldPopulation>();
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.listview_main);
editsearch = (EditText) findViewById(R.id.search);
list = (ListView) findViewById(R.id.listview);
tf = Typeface.createFromAsset(getAssets(), "fonts/BKOODB.TTF");
country = new String[54];
for (int x = 1; x < 54 + 1; x = x + 1) {
String this_subject = "mo_" + String.valueOf(x);
int resID = getResources().getIdentifier(this_subject, "string", getPackageName());
country[x - 1] = getResources().getString(resID);
}
for (int i = 0; i < 54; i++) {
WorldPopulation wp = new WorldPopulation(country[i]);
// Binds all strings into an array
arraylist.add(wp);
}
adapter = new ListViewAdapter(this, arraylist);
list.setAdapter(adapter);
editsearch.addTextChangedListener(new TextWatcher() {
#Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub

try doing it in afterTextChanged Method because this allows you to enter all the text. and follow this link
public void afterTextChanged(Editable s) {
}

Try with custom adapter.
this will help you.Link

onclick button is not working in listview

My project contains listView(homelistView) that contains button(btnList).
When I click on button(btnList) it must go to another Activity. I tried a lot but I didn't find a good example.
Please suggest me a good example regarding this.
Below is my code:
Here is my listview contains button. When on click of button it must go to other activity
--------------------------------A--
text text button(btnList) B
--------------------------------C---
text text BUTTON(btnList) D
--------------------------------E--
homempleb.xml
Before i used this code in xml. buttonlist worked fine for me as per below code
<ListView
android:id="#+id/homelistView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1.04"
android:dividerHeight="0dip" >
</ListView>
EfficientAdapter.java
public EfficientAdapter(Context context) {
mInflater = LayoutInflater.from(context);
this.context=context;
}
In your ViewHolder class you need to add `Button btnList.`
holder.btnList.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent next=new Intent(context, SeviceDetails.class);
context.startActivity(next);

The problem is in onInterceptTouchEvent method. You are using IndexableListView from woozzu, and this class overrides onInterceptTouchEvent to return true. This means that IndexableListView always steal touch events from your child's views so it can provide it to IndexScroller. You can change this behavior if instead of returning true you enter this condition:
#Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
if (mScroller != null && mScroller.contains(ev.getX(), ev.getY()))
return true;
return super.onInterceptTouchEvent(ev);
}
This way only events meant to interact with IndexScroller will be consumed. Other events will be propagated to children's views, and your button will be clickable.

In your Efficient adapter class declare ViewHolder holder outside getView method
and do as MoshErsan said.
Also Change your
convertView = mInflater.inflate(R.layout.homemplebrowview, null);
to
convertView = mInflater.inflate(R.layout.homemplebrowview, parent,false);

in your adapter, just move
holder.btnList.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(context, "STAT", Toast.LENGTH_SHORT).show();
Intent next = new Intent(context, Home.class);
Log.i("next23", "next");
context.startActivity(next);
}
});
just before return convertView;
you need to set the listener every time the adapter returns a view.

First remove btnList, btnScan from your MainActivity class.
In your EfficientAdapter class add object Context Context
Change your contructor:
public EfficientAdapter(Context context) {
mInflater = LayoutInflater.from(context);
}
to:
public EfficientAdapter(Context context) {
mInflater = LayoutInflater.from(context);
this.context=context;
}
In your ViewHolder class you need to add Button btnList.
Then in getview method find its view using holder.btnList
Then use:
holder.btnList.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent next=new Intent(context, SeviceDetails.class);
context.startActivity(next);
}
});
in your getview method before return convertView.

try this..
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null){
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.list_layout_ip_addtional_users, null);
}
//Handle TextView and display string from your list
TextView listItemText2 = (TextView)view.findViewById(R.id.list_item_string_name);
listItemText2.setText(list.get(position));
ImageButton button8 = (ImageButton) view.findViewById(R.id.ip_additional_user_edit);
button8.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(context, IPAdditionalUsersEdit.class);
context.startActivity(intent);
}
});
return view;
}
