super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView = findViewById(R.id.listview);
final CustomAdapter customAdapter = new CustomAdapter();
listView.setAdapter(customAdapter);
editsearch = findViewById(R.id.search);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

Toast.makeText(getApplicationContext(),fruitNames[i],Toast.LENGTH_LONG).show();
Intent intent = new Intent(getApplicationContext(),Listdata.class);
intent.putExtra("name",fruitNames[i]);
intent.putExtra("image",fruitImages[i]);
startActivity(intent);
}
});
}

imageView = findViewById(R.id.imageView);
Intent intent = getIntent();
String receivedName = intent.getStringExtra("name");
int receivedImage = intent.getIntExtra("image",0);
listdata.setText(receivedName);
imageView.setImageResource(receivedImage);
//enable back Button
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == android.R.id.home) {
onBackPressed();
}
return super.onOptionsItemSelected(item);

super.onBackPressed();
}
}
I have defined the SearchBox in android XML and it's working, the only problem is putting action in the search box.

Your listview needs a height, it cannot be wrap_content. Give it a height like 500dp or match_parent.

Replace the below
InviteUsersListRow rowUser = new InviteUsersListRow(R.id.profileImage, R.id.imageButtonInviteUser, name, mobile);
with
InviteUsersListRow rowUser = new InviteUsersListRow(R.drawable.camera, R.drawable.add_user_50, name, mobile);
The pic should be from "R.drawable" not from "R.id"
You should actually set an image resource below and not an id
holder.imageView.setImageResource(rowItem.getImageId());
holder.imgStatus.setImageResource(rowItem.getImageStatus());
In the above code you are not setting a drawable item.

How to add Listeners of Dynamic Check Boxes in Simple Adapter

I have dynamic CheckBoxes and now I want to check which CheckBox clicked or not
AdditionalInformation.Java File Here Simple Adapter is defined :
package com.example.ahmad.cvbuilder21;
import android.content.Intent;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.Gravity;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.CheckBox;
import android.widget.ListView;
import android.widget.SimpleAdapter;
import android.widget.TextView;
import android.widget.Toast;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
public class AdditionalInformation extends ActionBarActivity {
CheckBox cb;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_additional_infromation);
cb=(CheckBox)findViewById(R.id.additionalchk);
ABC s = ABC.getSingletonObject();
String[][] str = s.getString();
ListView lv=((ListView)findViewById(R.id.additionallist));
String[] additionalOptions={"Add your Picture","Add Experince / Project","Add Reference","Add Skills / Languages"};
String[] txtViewNames={"options"};
List<HashMap<String,String>>list=new ArrayList<HashMap<String, String>>();
for (int i = 0; i < additionalOptions.length; i++) {
HashMap<String, String> map= new HashMap<String, String>();
map.put("options", additionalOptions[i]);
list.add(map);
}
SimpleAdapter simpleAdpt = new SimpleAdapter(this, list, R.layout.mylayout2,txtViewNames , new int[] {R.id.additionaltxt1});
lv.setAdapter(simpleAdpt);
}
public void additionalData(View view1)
{
if(cb.isChecked())
{
cb.findViewById(R.id.additionalchk).setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View view)
{
Toast toast = Toast.makeText(getApplicationContext(), "Checked",
Toast.LENGTH_SHORT);
toast.setGravity(Gravity.TOP|Gravity.LEFT, 0, 0);
toast.show();
}
}
);
}
else{}
}
}
AdditionalInformation.xml file: where additionalData function is called to
check which CheckBox clicked.
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Choose Additional Options:"
android:id="#+id/additionalBtn"
/>
<ListView
android:layout_below="#id/additionalBtn"
android:layout_centerHorizontal="true"
android:id="#+id/additionallist"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></ListView>
<Button
android:layout_below="#id/additionallist"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Add to CV"
android:onClick="additionalData"
/>
</RelativeLayout>
mylayout2.xml file where I define the controls for simple adapter:
<?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">
<TextView
android:layout_alignParentLeft="true"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="#+id/additionaltxt1"
/>
<CheckBox
android:layout_alignParentRight="true"
android:layout_alignRight="#id/additionaltxt1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checked="false"
android:id="#+id/additionalchk"
/>
</RelativeLayout>

What you actually need to do is create a custom adapter. In that custom you could listen for checkbox event at the right position.
Here is an example:
public class ListEmployeesAdapter extends BaseAdapter {
public List<Employees> items;
Context c;
public ListEmployeesAdapter(Context c, List<Employees> items) {
this.c = c;
this.items = items;
}
#Override
public int getCount() {
return items.size();
}
#Override
public Object getItem(int position) {
return items.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater mInflater = (LayoutInflater)
c.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.employee_item, null);
}
TextView name = (TextView) convertView.findViewById(R.id.name);
name.setText(items.get(position).name);
name.setOnCLickListener(new OnClickListener(){
#Override
public void onClick(){
//listen to the click
}
});
return convertView;
}
}
Just replace the the layout with you layout and call checkbox instead of TextView and you are good to go.

How to let a user add and remove items to a ListView?

I am trying to make it so that when a user clicks a button, it pops up a dialog with an EditText and an OK Button. When the user completes, the dialog, it should add the item they just typed in to the ListView. How do I do this?
I will need a large code example; this is my first application.

You'll want to follow the official notepad tutorial example. It's very comprehensive. It does 95% of what you want to do.
http://developer.android.com/resources/tutorials/notepad/index.html

Well here is a sample code. There is a button to add text in list and long press on list item will remove it.
activity_main.xml
<LinearLayout 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:orientation="vertical" >
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="Add Item" />
<ListView
android:id="#+id/list_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
dialog_layout.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"
android:orientation="vertical" >
<EditText
android:id="#+id/edit_box"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:inputType="text" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:orientation="horizontal"
android:weightSum="2" >
<Button
android:id="#+id/button_ok"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="OK" />
<Button
android:id="#+id/button_cancel"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="CANCEL" />
</LinearLayout>
