Adding onClickListener to specific items in ListView

please I'm trying to add understand how to add onItemClickListener to the followng code such that when "Smartphone Plans" is clicked, its activity starts and so on. I've seen other questions on StackOverflow relating to this question but do not understand how to go about them.
I've already added an onItemClickListener but do not understand how to set it to specific list items.
here is the code
package devchuks.com.rechargeit;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.app.ListActivity;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;
public class EtisalatData extends AppCompatActivity {
ListView listView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_etisalat_data);
listView = (ListView) findViewById(R.id.list);
String[] values = new String[] {
"Smartphone Plans",
"Internet Bundles",
"Weekend Plans",
};
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, android.R.id.text1, values);
listView.setAdapter(adapter);
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
}
});
}
}

You can define your listView.setOnItemClickListener like this to go to different activity for clicking different element.
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
String item = listView.getItemAtPosition(position);
Toast.makeText(this,"You selected : " + item,Toast.LENGTH_SHORT).show();
if(position==0) {
// Do your code for clicking "Smartphone Plans" example
// startActivity(new Intent(getApplicationContext(),SmartphonePlans.class));
}
else if(position==1) {
// Do your code for clicking "Internet Bundles". example
// startActivity(new Intent(getApplicationContext(),InternetBundles.class));
}
else if(position==2) {
// Do your code for clicking "Weekend Plans". example
//startActivity(new Intent(getApplicationContext(),WeekendPlans.class));*/
}
});

onItemClick will be called whenever any of the list items are clicked. The position will be the position of the view in the Adapter.

Thanks

try this:
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
String text = values[position];
if(text.equals("Smartphone Plans")){ //your specific list item text
Intent i = new Intent(MainActivity.this, AnotherActivity.class);
i.putExtra("TEXT", text);
startActivity(i);
}
}
}

If this helps and is your concern
`
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
String data = values[position];
switch(data){
case "Smartphone Plans":
// do somwthing
break;
// similarly for other two values.
}
}
});`

Below method give you a position of a clicked row. Take advantage of that and value from your array.
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// Move your values array to member array or make it final to use
// in Anonymous class
final String selectedValue = values[position];
Intent intent = null
// Now add case and start activity
if("Smartphone Plans".equals(selectedValue)) {
intent = new Intent(EtisalatData.this, SmartPhonePlan.class);
}
else if("other Plans".equals(selectedValue)){
// other action
}
//... more cases and at the end start your activity if its not null
startActivity(intent);
}

Simple list item multiple choice not selecting items

I've created an array list and display it in a list view with simple list item multiple choice but i cannot check or tick the items on the list, when i click on the items nothing happens. Please check my code below and tell me what i am doing wrong.
package com.example.arrays;
import java.util.Random;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemLongClickListener;
public class MainActivity extends Activity {
ListView showList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final TextView show = (TextView)findViewById(R.id.txtShow);
final Random generate = new Random();
showList = (ListView)findViewById(R.id.listView1);
final String[] myAttraction = new String[4];
myAttraction[0]= "Walter Sisulu National Botanical Garden ";
myAttraction[1]= "Coca-Cola Dome";
myAttraction[2]= "Promusica Theatre";
myAttraction[3]= "Unisa Science Campus";
Button arrays = (Button)findViewById(R.id.button1);
arrays.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
/*int random = generate.nextInt(4);
String display = myAttraction[random];
show.setText(display);*/
ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_multiple_choice, myAttraction);
showList.setAdapter(adapter);
}
});
showList.setOnItemLongClickListener(new OnItemLongClickListener() {
public boolean onItemLongClick(AdapterView<?> arg0, View arg1, int pos, long id) {
// TODO Auto-generated method stub
Toast.makeText(getBaseContext(), "long clicked pos: " + pos, Toast.LENGTH_LONG).show();
return true;
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}

Add a OnItemClickListener like this to check/uncheck the CheckedTextView when user click on an item
showList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// change the checkbox state
CheckedTextView checkedTextView = ((CheckedTextView)view);
checkedTextView.setChecked(!checkedTextView.isChecked());
}
});

change your code as following....
ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_multiple_choice, myAttraction);
showList.setAdapter(adapter);
arrays.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
/*int random = generate.nextInt(4);
String display = myAttraction[random];
show.setText(display);*/
}
});
showList.setOnItemClickListener(new OnItemClickListener() {
public boolean onItemClick(AdapterView<?> arg0, View arg1, int pos, long id) {
// TODO Auto-generated method stub
Toast.makeText(getBaseContext(), "long clicked pos: " + pos, Toast.LENGTH_LONG).show();
return true;
}
});

Set choiceMode property of your list to multipleChoice. I'm implementing multiple choice list in such a way in my applications, and it surely works.

Change this
ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this,android.R.layout.simple_list_item_multiple_choice, myAttraction);
showList.setAdapter(adapter);
To this
ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this,android.R.layout.simple_list_item_multiple_choice, myAttraction);
showList.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
showList.setAdapter(adapter);
Just Add this line if you have a ListView and have selected simple_list_item_multiple_choice and you are unable to interact with the checkbox.
YourListViewName.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);

Listview to another layout. Is it possible?

I am a beginner. How will my string can be a clickable one that can redirect to other layout. or different layouts.
EDITED
This is my MainActivity.java:
public class MainActivity extends Activity {
String[] country = new String[] {
"China",
"India",
"Sri Lanka",
"Malaysia",
"Japan",
};
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.listview_layout, country);
ListView listView = (ListView) findViewById(R.id.listView);
listView.setAdapter(adapter);
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
Intent in = new Intent(MainActivity.this,PageOne.class);
startActivity(in);
};
});
}
and This is the PageOne.class
public class PageOne extends Activity implements OnClickListener{
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.china);
getIntent().getStringExtra("China");
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
}
I wanted to do is when India is Click it will go to India.xml
And if China is click it will go to China.xml but what happening is any String I click the result is china.xml.

You need to use base adapter for that, and open another activity an click of the row.
Example
you can also use listview onitem click listener
and open the respective activity with respect to the position.

Assume you want listview row which contains strings to be clickable.
listview.setOnItemClickListener(new OnItemClickListener()
{
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
Intent i= new Intent("com.example.secondactivity");
i.putExtra("value", country[arg2]);
// pass country based on listview position
//value- is the key
// second parameter is the actual value ie country name
startActivity(i);
}
});
country[arg2] . arg2 is the position of the listview. Items in listview are populated based on the position. When listview row is clicked country[arg2] is name of the country in that listview position. So you pass the value to the secondactivity using intent.
To retrieve in Second Activity's onCreate()
Intent intent = getIntent();
Bundle b = intent.getExtras();
String country = b.getString(key);//value or china in youe case.
Make sure second activity has an entry in manifest file
EDIT:
<activity
android:name="com.example.test1.secondactivity"
>
<intent-filter>
<action android:name="com.example.test1.secondactivity" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
MainActivity with listview.

import android.widget.ListView;
public class MainActivity extends Activity {
String[] country = new String[] {
"India",

#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// R.layout.listview_layout is the custom layout
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, android.R.id.text1, country);
//this refers to the actiivty context,
//second parameters says its a simple list item
//third is id of text
//country is your array of string
ListView listView = (ListView) findViewById(R.id.lv);
listView.setAdapter(adapter);
listView.setOnItemClickListener(new OnItemClickListener()
{
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
Intent i= new Intent("com.example.test1.secondactivity");
i.putExtra("value", country[arg2]);
// pass country based on listview position
//value- is the key
// second parameter is the actual value ie country name
startActivity(i);
}
});
}
}
Second Actiivty which has a textview.
public class secondactivity extends Activity{
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.second);
TextView tv= (TextView) findViewById(R.id.textView1);
Bundle extras = getIntent().getExtras();
if (extras != null) {
String country = extras.getString("value");//value or china in youe case
tv.setText(country);
}
}
}
Project folder

Try to make a listener on your list view item and navigate by intent to next activity.
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
Intent in = new Intent(MainActivity.this,SecondActivity.class);
startActivity(in);
};
});

Click on item of customlist-view is not working

This is my code for click on a customlistview. When I click on the header, it works but after header its not working. CustomAdapter is another class in my App where I have defined header and all variables of listview. Please help me to resolve this problem.
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.text.Html;
import android.view.View;
import android.widget.AdapterView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;
public class ProbabilityConditional extends Activity {
String htmlcodefor_root = "&#x221A", htmlcodefor_multiply = "&#xD7",
htmlcodefor_divide = "&#xF7", htmlcodefor_underroot = "&#00B3";
ListView listView1;
String htmlcodefor_space = "&#8194", htmlcodefor_pi = "&#928",

String htmlcodefor_implies = "&#x21D2";
String htmlcodefor_i = "&#7522";
String htmlcodefor_angle = "&#952";
String htmlcodefor_overline = "&#x203E", htmlcodefor_plusminus = "&#177";
// TextView txtv;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// txtv = (TextView)findViewById(R.id.txtTitle);
// txtv.setText(Html.fromHtml("1.(constant)<sup><small>0</></> = 1"));
listView1 = (ListView) findViewById(R.id.listView1);
CustomAdapter.formula_one_custom_adapter_class_var = Html.fromHtml("1 ");
CustomAdapter.formula_two_custom_adapter_class_var = Html.fromHtml("2 ");
CustomItemCall formula_data[] = new CustomItemCall[] {
new CustomItemCall(CustomAdapter.formula_one_custom_adapter_class_var),
new CustomItemCall(CustomAdapter.formula_two_custom_adapter_class_var),
};
CustomAdapter adapter = new CustomAdapter(this,R.layout.listview_item_row, formula_data);
View header = (View) getLayoutInflater().inflate(R.layout.listview_header_row, null);
listView1.addHeaderView(header);
listView1.setAdapter(adapter);
listView1.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,int position, long id) {
System.out.println(position);
Toast.makeText(ProbabilityConditional.this,position + " " , Toast.LENGTH_LONG).show();
// When clicked, show a toast with the TextView text
if (position == 1) {
startActivity(new Intent(ProbabilityConditional.this,ProbabilityConditionalDiscrete.class));
} if (position == 2) {
startActivity(new Intent(ProbabilityConditional.this,ProbabilityConditionalContinuous.class));
}
}
});
}
}

make your listview focusable true add these line in your xml android:focusable="true"
and make other item of list make false android:focusable="false "
listView1.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,int position, long id) {
System.out.println(position);
Toast.makeText(ProbabilityConditional.this,position + " " , Toast.LENGTH_LONG).show();
// When clicked, show a toast with the TextView text
if (position == 1) {
startActivity(new Intent(ProbabilityConditional.this,ProbabilityConditionalDiscrete.class));
} if (position == 2) {
startActivity(new Intent(ProbabilityConditional.this,ProbabilityConditionalContinuous.class));
}
}
});

write code like this, simple way:-
ListView list;
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View view,
int position, long id)
{
//if in future you need to start a new activity
//then add below line also in your activity
Intent in = new Intent(MainActivity.this, SecondActivity.class);
startActivity(in);
}
});

Android on click listener to pass json variables

I have a ListView and Iwant it so that, when you click on an item in the list it takes you to another activity, but with the variable of what I clicked.
For example, ifIi have item1, item2, item3 I want it so that, when i click on item1 it takes me to another activity and in that other activity everything that would be inside item1, in the json feed, gets displayed .
Here is my code so far:
import java.util.ArrayList;
import java.util.List;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import android.app.ListActivity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;
public class ChooseTeamActivity extends ListActivity {
public String FullData = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.chooseact);
final String FullData = getIntent().getStringExtra("FullData");
Log.v("lc", "chooseActivity:" + FullData);
try{
JSONObject obj = new JSONObject(FullData);
List<String> leagues = new ArrayList<String>();
JSONObject objData = obj.getJSONObject("data");
JSONArray jArray = objData.getJSONArray("structure");
for (int i=0; i < jArray.length(); i++)
{ JSONObject oneObject = jArray.getJSONObject(i);
JSONArray DivisionsArray = oneObject.getJSONArray("divisions");
for (int d=0; d < DivisionsArray.length(); d++){
JSONObject DivDict = DivisionsArray.getJSONObject(d);
leagues.add(DivDict.getString("name"));
}
}
setListAdapter ( new ArrayAdapter<String>(this, R.layout.single_item, leagues));
ListView list = getListView();
list.setTextFilterEnabled(true);
list.setOnItemClickListener(new OnItemClickListener(){
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
//Toast.makeText(getApplicationContext(), ((TextView) arg1).getText(),1000).show();
Intent nextScreen = new Intent(getApplicationContext(), ChooseTeamActivity.class);
nextScreen.putExtra("FullData", FullData);
startActivity(nextScreen);
}
});
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

Keep a field reference to DivisionArray, then override onListItemClicked to get the index of the clicked item, then look up that item in DivisionArray:
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
// TODO: Add code here to look up the item in DivisionArray by index, then use
// that to launch an activity either with the index or the JSON structure as an extra
}
Once you have the index, you can launch an activity with the index, or the JSON structure:
Intent intent = new Intent(this, MyActivity.class);
intent.putExtra("selectedItem", /* TODO: use the index to the item or the JSON structure itself here */);
startActivity(intent);

Override the click event handler:
#Override
protected void onListItemClick (ListView l, View v, int position, long id) {
}
And add code there for fire your activity with a parameter (your json stuff for example, or a way to get it)
Intent intent = new Intent(this, DetailedActivity.class);
//leagues.get(position);
//or just use the position:
foo.putExtra("itemIndex", position);
//foo.putExtra("fullData", FullData); //or just the part you want
startActivity(foo);

You could use the setOnItemClickListener() method and use intents to pass the String of the Data that is to be displayed as follows on the list
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Bundle b = new Bundle();
b.putString("itemData",data[poition]);
Intent intent = new Intent(Activity1.this,Activity2.class);
intent.putExtras(b);
startActivity(intent);
}
});
Here the data[] is an array of strings which contains the data that is to be passed from Activity1 to Activity2. Activity 1 is the current activity and you can fix Activity2 also, just populate it with different data.

Use this code.
yourListView.setOnItemClickListener(new OnItemClickListener()
{
public void onItemClick(AdapterView<?> arg0, View arg1, final int position, long arg3)
{
Intent intent = new Intent(YourActivity.this, NotesActivity.class);
intent.putExtra("Date", "Item To Pass In Ur Activity");
startActivity(intent);
}
});
On your Activity write the following code to get the item that are pass by your listview
String selectedDate = getIntent().getStringExtra("Date");
