So I have two fragments linking to layout files which display ListViews. The ListViews are defined in the xml and have entries from a string array. I want to click on items in the ListView and open new activities. There are 8 items in one ListView and 9 in the other. In the onItemClick code, how do I create intents to start activities based on the item clicked? I will create 1 class per item as its own activity. How can I start the activities in the classes via intents inside the onItemClick methods of this code?
class CommunityFragment extends Fragment{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View view = inflater.inflate(R.layout.community_fragment, container, false);
ListView lv = (ListView) view.findViewById(R.id.communityListView);
lv.setOnItemClickListener(new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3){
// TODO Auto-generated method stub
}
});
return view;
}
}
class ResourcesFragment extends Fragment{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View view = inflater.inflate(R.layout.resources_fragment, container, false);
ListView lv = (ListView) view.findViewById(R.id.resourcesListView);
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
// TODO Auto-generated method stub
}
});
return view;
}
}
Implement your OnItemClickListener() like below
listview.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1,
int position, long arg3) {
// TODO Auto-generated method stub
Intent intent = new Intent(getActivity(), nextactivity.class);
startActivity(intent);
}
});
Make switch statement for each items click and open activities accordingly as below:
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
// TODO Auto-generated method stub
int itm=arg0.getItemAtPosition(arg2);
switch (itm) {
case 0:
Toast.makeText(m_context, "Position Zero", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(getActivity(), FirstActivity.class);
startActivity(intent);
break;
case 1:
Intent intent1 = new Intent(getActivity(), SecondActivity.class);
startActivity(intent1);
break;
case 2:
//..............................
}
});
on Item Click you will get Position based on position you can start fragment
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Toast.makeText(getApplicationContext(),
"Click ListItem Number " + position, Toast.LENGTH_LONG)
.show();
switch(position) {
case CONST_FRAGMENT_1 :
//Start fragment 1
...
...
}
}
});
one Generic solution can be ..
Create an array of items that hold class name of activity you want to open ..
like ..
Class[] activityArray = new Class[numberOfItemsInListView];
activityArray[0] = Activity1.class;
//add all activities like that..............
now on ListView onItemCLick :
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view,
int position, long arg3) {
Intent intent = new Intent(CommunityFragment.this.getActivity(), activityArray[postion]);
CommunityFragment.this.getActivity.startActivity(intent);
}
});
Use this to start next intent in your onItemClickListener:
Intent intent = new Intent(getActivity(), nextactivity.class);
startActivity(intent);
I think following code help you.
public class PdfListViewFragment extends Fragment {
ListView listView;
Activity rootView;
Activity context;
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
//returning our layout file
//change R.layout.yourlayoutfilename for each of your fragments
View rootView = inflater.inflate(R.layout.pdf_list_view, container, false);
context = getActivity();
// Get ListView object from xml
listView = (ListView) rootView.findViewById(R.id.list);
// Defined Array values to show in ListView
String[] values = new String[]{"Android List View",
"Adapter implementation",
"Simple List View In Android",
"Create List View Android",
"Android Example",
"List View Source Code",
"List View Array Adapter",
"Android Example List View"
};
// Define a new Adapter
// First parameter - Context
// Second parameter - Layout for the row
// Third parameter - ID of the TextView to which the data is written
// Forth - the Array of data
ArrayAdapter<String> adapter = new ArrayAdapter<String>(context,
android.R.layout.simple_list_item_1, android.R.id.text1, values);
// Assign adapter to ListView
listView.setAdapter(adapter);
// ListView Item Click Listener
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
if (position == 0) {
Intent myIntent = new Intent(view.getContext(), ListItemActivity1.class);
startActivityForResult(myIntent, 0);
}
if (position == 1) {
Intent myIntent = new Intent(view.getContext(), ListItemActivity2.class);
startActivityForResult(myIntent, 0);
}
if (position == 2) {
Intent myIntent = new Intent(view.getContext(), ListItemActivity1.class);
startActivityForResult(myIntent, 0);
}
if (position == 3) {
Intent myIntent = new Intent(view.getContext(), ListItemActivity2.class);
startActivityForResult(myIntent, 0);
}
if (position == 4) {
Intent myIntent = new Intent(view.getContext(), ListItemActivity1.class);
startActivityForResult(myIntent, 0);
}
if (position == 5) {
Intent myIntent = new Intent(view.getContext(), ListItemActivity2.class);
startActivityForResult(myIntent, 0);
}
if (position == 6) {
Intent myIntent = new Intent(view.getContext(), ListItemActivity1.class);
startActivityForResult(myIntent, 0);
}
if (position == 7) {
Intent myIntent = new Intent(view.getContext(), ListItemActivity2.class);
startActivityForResult(myIntent, 0);
}
// ListView Clicked item index
int itemPosition = position;
// ListView Clicked item value
String itemValue = (String) listView.getItemAtPosition(position);
// Show Alert
Toast.makeText(context.getApplicationContext(), "Position :" + itemPosition + " ListItem : " + itemValue, Toast.LENGTH_LONG).show();
}
});
return rootView;
}
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
//you can set the title for your toolbar here for different fragments different titles
getActivity().setTitle("XYZ");
}
}
If you use an adapter to display the items in a list, it is important to differentiate the following:
The ID of the list AdapterView#getId() is different than the ID of the items in the list ArrayAdapter<String>#getId(), because the view of the list contains the views of the elements.
Suppose an example where you are going to launch activities with user roles. You will have to do the transformation for your particular case.
public class SignInFragment extends Fragment implements AdapterView.OnItemClickListener {
//TODO: Declare constants (GUEST, HOST, EMPLOYEE...)
private ArrayAdapter<String> userRolesAdapter;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View root = inflater.inflate(R.layout.fragment_sign_in, container, false);
// ListView Instance
ListView userRolesList = root.findViewById(R.id.user_roles_list);
String[] userRoles = {
GUEST,
HOST,
EMPLOYEE
};
// Initialize the adapter
userRolesAdapter = new ArrayAdapter<>(
getActivity(),
android.R.layout.simple_list_item_1,
userRoles
);
// Link to the list with the adapter. This reference starts the process of filling the list.
userRolesList.setAdapter(userRolesAdapter);
// Events
userRolesList.setOnItemClickListener(this);
return root;
}
/**
* #param adapterView: View using the adapter from the list
* #param view: View of the item that has been pressed
* #param i: Refers to the position of the item that the adapter handles
*/
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
if (adapterView.getId() == R.id.user_roles_list) {
// Obtain the item pressed on the adapter with the entry position
String currentUserRol = userRolesAdapter.getItem(i);
assert currentUserRol != null;
switch (currentUserRol) {
case GUEST:
startActivity(Host.class);
break;
case HOST:
startActivity(Host.class);
break;
case EMPLOYEE:
startActivity(Employee.class);
break;
default:
Log.d("Error", "The activity passed as an argument to startActivity() does not exist");
break;
}
}
}
/**
* PRECONDITION: The class given as an argument exists.
*/
public void startActivity(Class<?> cls) {
Intent intent = new Intent(getActivity(), cls);
startActivity(intent);
}
}
Best :)

I want to start a new activity from list view items from a fragment. But this isn't working. Here's the code:
public class SettingsF extends Fragment {
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View root = (ViewGroup) inflater.inflate(R.layout.fragment_settings, container, false);
String[] menuitems = {"Context Setup", "Set-Up Custom Texts"};
ListView listView = (ListView) root.findViewById(R.id.listview_settings);
ArrayAdapter<String> listViewAdapter = new ArrayAdapter<String>(getActivity(),
android.R.layout.simple_list_item_1, menuitems);
listView.setAdapter(listViewAdapter);
listView.setOnClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if (position == 1){
Intent intent;
intent = new Intent(getActivity(), contactselect.class);
startActivity(intent);
}
}
});
return root;
}
If you want to use event listener on ListView then you can use listview.setOnItemClickListener(new AdapetView). This (setOnClickListener) listener can't work on listview.
Listview contain multiple data.
Try this if you want to open an activity on item clicked:
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// your code
}
});
I have a listview inside a fragment class. When a listview item is clicked another activity is opened. The xml file of that activity has 2 imageviews inside a scroll view. The images change with respect to every listview item clicked. No matter which listview item i click on it shows the same image view. In my case it shows the R.drawable.geet94 no mater which listview item i click.
public class urdufrag1 extends Fragment {
public urdufrag1() {
// Required empty public constructor
}
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
}
private static final String TAG = "urdufrag1";
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup
main_content, #Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.geetfrag_urdu, main_content, false);
final int[] menuImage = {R.drawable.tgeet94,
R.drawable.tgeet95,R.drawable.tgeet96,R.drawable.tgeet97};
final ListView listView = (ListView) view.findViewById(R.id.GeetListU);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
Intent intent = new Intent(getActivity(), PackageG.class);
//intent.putExtra("GeetType",
listView.getItemAtPosition(position).toString());
//intent.putExtra("GeetType", Integer.toString(position));
intent.putExtra("position", Integer.toString(position));
startActivity(intent);
}
});
AdapterGeetUrdu adapter = new AdapterGeetUrdu(getContext(), menuImage);
listView.setAdapter(adapter);
// Inflate the layout for this fragment
return view;
}
}
Second Activity
public class PackageG extends AppCompatActivity {
ImageView img1, img2;
PhotoViewAttacher mAttacher;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_package_g);
img1 = (ImageView) findViewById(R.id.imageView8);
img2 = (ImageView) findViewById(R.id.imageView9);
mAttacher = new PhotoViewAttacher(img1);
mAttacher = new PhotoViewAttacher(img2);
Intent intent = this.getIntent();
if(intent != null){
Integer position = intent.getExtras().getInt("position");
switch (position){
case 0: img1.setImageResource(R.drawable.geet94);
img2.setImageResource(R.drawable.geet94_1);
break;
case 1: img1.setImageResource(R.drawable.geet95);
img2.setImageResource(R.drawable.geet95_1);
break;
case 2: img1.setImageResource(R.drawable.geet96);
img2.setImageResource(R.drawable.geet96_1);
break;
default:
img1.setImageResource(R.drawable.carol);
img2.setImageResource(R.drawable.carol);
break;
}
}
mAttacher.update();
}
}
intent.putExtra("position", Integer.toString(position));
This is where you made mistake.
Change this to, and will solve your problem.
intent.putExtra("position", position);
Because in your activity you are expecting an integer but you are passing string position from listview. Change the click listener as per the below code
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
Intent intent = new Intent(getActivity(), PackageG.class);
intent.putExtra("position", position);
startActivity(intent);
}
});
Am having problem with my code.. am trying to add a search function to my list view in android.. it is somehow working but when i search it gave me other activity not the real result.. Like in my listview if i search for sale i.e the 5th activity it shows the result but when i click to open the activity it open Sani activity i.e the first activity on the list...
Here is the Activity Java Code
package com.example.bati;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.SearchView;
import android.widget.SearchView.OnQueryTextListener;
public class MainActivity extends Activity {
ListView lv;
SearchView sv;
String[] teams = {"Sani", "Bali", "Sati", "Umam", "sale"};
ArrayAdapter<String> adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lv = (ListView) findViewById(R.id.listView1);
adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, teams);
lv.setAdapter(adapter);
sv.setOnQueryTextListener(new OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
adapter.getFilter().filter(newText);
return false;
}
});
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if (position == 0) {
Intent myIntent = new Intent(view.getContext(), Sani.class);
startActivityForResult(myIntent, 0);
}
if (position == 1) {
Intent myIntent = new Intent(view.getContext(), Bali.class);
startActivityForResult(myIntent, 1);
}
if (position == 2) {
Intent myIntent = new Intent(view.getContext(), Sati.class);
startActivityForResult(myIntent, 2);
}
}
});
}
}
When you filter your adapter and notify with the result your item's positions change you you cannot use position as an identifier to open activity. Your search data changes but you're always clicking the position 0 so always Sani activity gets opened.
Here i modified your code a bit:
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
final String item = (String)parent.getItemAtPosition(position);
if ("Sani".equals(item)) {
Intent myIntent = new Intent(view.getContext(), Sani.class);
startActivityForResult(myIntent, 0);
}
if ("Bali".eqauls(item)) {
Intent myIntent = new Intent(view.getContext(), Bali.class);
startActivityForResult(myIntent, 1);
}
if ("Sati".equals(item)) {
Intent myIntent = new Intent(view.getContext(), Sati.class);
startActivityForResult(myIntent, 2);
}
}
});
I think this'll help you.
The position the ListView gives you in onItemClick is the position of the clicked item from the top of the currently visible items in the ListView. Since the list view is filtered, the position may not be equal to the item position in teams array.
You can get the item at the position from the adapter itself. Following code will work for you.
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String item = adapter.getItem(position);
switch (item) {
case "Sani":
startActivityForResult(new Intent(view.getContext(), Sani.class), 0);
return;
case "Bali":
startActivityForResult(new Intent(view.getContext(), Bali.class), 1);
return;
case "Sati":
startActivityForResult(new Intent(view.getContext(), Sati.class), 2);
return;
}
}
});
I have a listview and want to set an onClickListener on each item in this fragment but it's not working.I also wanted to set a contextMenu on the listview and that's not working either.
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
purchasedItemsView = inflater.inflate(R.layout.purchased_items_fragment , container, false);
db = new StoreDataBase(getActivity() , Consts.StoreDB.DB_NAME , Consts.StoreDB.DB_VERSION);
storeArrayList = new ArrayList<>();
listView = (ListView) purchasedItemsView.findViewById(R.id.storeListView);
adapter = new StoreListViewAdapter(getContext() , R.layout.store_item_row , storeArrayList);
listView.setAdapter(adapter);
adapter .notifyDataSetChanged();
registerForContextMenu(listView);
sendData(purchasedItemsView);
return purchasedItemsView;
}
private void sendData(View view){
Bundle bundle = getArguments();
if (bundle != null) {
final String[] names = bundle.getStringArray(Constc.Data.names);
listView = (ListView) view.findViewById(R.id.storeListView);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Log.e("Data" , "clicked");
}
});
}else{
}
}
Don't reinitialize listview after you have done it once in onCreateView(). Therefore, remove this line from sendData() method:
// remove this
listView = (ListView) view.findViewById(R.id.storeListView);
Then you need to move this part of code outside of if statement or inside of onCreateView() method.
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Log.e("Data" , "clicked");
}
});
Point 1:
Seems your array list is empty, so fill some data
storeArrayList = new ArrayList<>();
//-------------------------------------
Bundle bundle = getArguments();
if (bundle != null) {
final String[] names = bundle.getStringArray(Constc.Data.names);
if(names != null && names.length() > 0) {
storeArrayList.addAll(names);
}
}
//-------------------------------------
listView = (ListView) purchasedItemsView.findViewById(R.id.storeListView);
adapter = new StoreListViewAdapter(getContext() , R.layout.store_item_row , storeArrayList);
listView.setAdapter(adapter);
Point 2: You don't need "notifyDataSetChanged();" right after you set the adapter.
//adapter .notifyDataSetChanged();
Point 3:
Use long click listener for showing context menu
listView.setOnItemLongClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
Log.e("Data" , "long press clicked");
//show dialog or context menu dialog.
}
});
Point 4:
comment the sendData method and use the onclick directly
//sendData(purchasedItemsView);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Log.e("Data" , "clicked");
}
});
Hope this helps.

Hey everyone I've looked for hours trying to find a solution to this, my goal is to have a Listview when it opens well open another activity. Well actually I got it to be able to open another activity when its click but how do I get it so that each list item will open its own activity? I am terribly sorry if this question is already answered but the links I found doesn't really describe what the code is doing [Yes i am a newbie :)]
this is the code im using
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String[] countries = getResources().getStringArray(R.array.countries_array);
setListAdapter(new ArrayAdapter<String>(this, R.layout.newfile, countries));
ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
Intent myIntent = new Intent(view.getContext(), Html_file.class);
startActivityForResult(myIntent, 0);
}
});
}
}
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
if(position == 1) {
//code specific to first list item
Intent myIntent = new Intent(view.getContext(), Html_file1.class);
startActivityForResult(myIntent, 0);
}
if(position == 2) {
//code specific to 2nd list item
Intent myIntent = new Intent(view.getContext(), Html_file2.class);
startActivityForResult(myIntent, 0);
}
}
});
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
switch( position ) {
case 0: Intent newActivity = new Intent(this, i1.class);
startActivity(newActivity);
break;
case 1: Intent newActivity = new Intent(this, i2.class);
startActivity(newActivity);
break;
case 2: Intent newActivity = new Intent(this, i3.class);
startActivity(newActivity);
break;
case 3: Intent newActivity = new Intent(this, i4.class);
startActivity(newActivity);
break;
case 4: Intent newActivity = new Intent(this, i5.class);
startActivity(newActivity);
break;
}
}
If you have some limited number of list you can use switch case here on position
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
Intent myIntent = new Intent(view.getContext(), Html_file.class);
startActivityForResult(myIntent, 0);
}
});
If you know which activity is to be opened when different list items are clicked, then just assign id or tag to the list items.
In the callback of onItemClick, you have a parameter View,
use it to get id or tag to differentiate them and call respective Activity.
// Add ArrayList and ArrayAdapter:
final ArrayList<String> listItems = new ArrayList<String>();
listItems.add("image_one");
listItems.add("image_two");
listItems.add("image_three");
ArrayAdapter<String> myArrayAdapter = new ArrayAdapter<>(this,
android.R.layout.simple_list_item_1, listItems);
myListView.setAdapter(myArrayAdapter);
// Add ArrayList of Classes:
final ArrayList<Class> intents = new ArrayList<Class>();
intents.add(image_one.class);
intents.add(image_two.class);
intents.add(image_three.class);
// Click on list item to open Class from ArrayList of Classes:
myListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int
position, long id) {
Intent listIntent = new Intent(getApplicationContext(),
intents.get(position));
startActivity(listIntent);
}
});
