Fetching List Item Click

I have 2 activity in my app.
From First activity I take data to second activity's listview. In second activity I have a listview to show datas. Normally when I create a list and values myself I can create click event but now datas coming from other activity, and the datas uncertain.. How can I create click event for coming datas?(sorry for my very bad grammar)
It's my first activity;
Intent veri = new Intent(elementler.this,sonuclar.class);
veri.putStringArrayListExtra("logoveri", clickeddata);
startActivity(veri);
//I sent data for second activity's list
It's my list class;
//fetch values
Intent veri = getIntent();
veriler = veri.getStringArrayListExtra("logoveri");
//there are a lot of possibility in "veriler" maybe user select banana maybe apple maybe car maybe computer we can not know what he select..
//create a list with fetch data
ListView sonuclistesi=(ListView) findViewById(R.id.sonuclistesi);
ArrayAdapter<String> veriadaptoru=new Listeozellikleri(this,veriler);
sonuclistesi.setAdapter(veriadaptoru);

You can give listView onitem click,
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// do your stuff
}
});

Add item from activity(form) to listfragment

add expense item
expense history
Input the form in image 1 and click the OK button, pass data from image 1 to image 2.
How to add item from one activity to expense history (another activity)?

You need to do the following:
//in the Activity
eventsList = new ArrayList<HashMap<String, String>>();
// selecting single ListView item
ListView lv = getListView();
// Lauching the Event details screen on selecting a single event
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// getting values from selected ListItem
String ID = ((TextView) view.findViewById(R.id.pid))
.getText().toString();
Intent intent = new Intent(view.getContext(),
EventDetails.class);
intent.putExtra(pid, ID);
view.getContext().startActivity(intent);
}
});
Basically what you are doing is passing the id of the selected item in the listview to then the details in the fragment of that activity. Each time a different item is selected, a different details are shown. For further reference, take a look at this tutorial.

Android ListView Populated from XML won't send data to new activity

I have an array located in my strings.xml file that looks like the following.
<string-array name="array123">
<item>test1</item>
<item>test2</item>
<item>test3</item>
<item>test4</item>
<item>test5</item>
</string-array>
My listview is properly displayed on Activity 1, here is my onItemClick code
public void onItemClick(AdapterView<?> adapter, View view, int position, long id) {
Intent activityIntent = new Intent(this, Activity2.class);
String selectedItem = adapter.getSelectedItem().toString();
activityIntent.putExtra("my.package.dataToPass", selectedItem);
startActivity(activityIntent);
As soon as I tap an item from the list the screen just goes black and the application crashes. Here is my code for Activity 2
Bundle recdData = getIntent().getExtras();
String myVal = recdData.getString("my.package.dataToPass");
TextView word = (TextView) findViewById(R.id.word);
word.setText(myVal);
I'm not sure why this isn't working. I'm just trying to pass the string that was selected to show as text on the 2nd activity. I've been searching for a day and a half now.
I did try
activityIntent.putExtra("my.package.dataToPass", id);
but this just seemed to pass an empty screen.
Any help would be much appreciated. Obviously I'm not passing the right data in the intent.

As I can see, you are implementing the Click listener (onItemClick) rather than Select listener(onItemSelected). By default when you click on a ListView item it doesn't change its state to "selected"
Plz use adapter.getItem(position) instead of adapter.getSelectedItem()
public void onItemClick(AdapterView<?> adapter, View v, int position, long id) {
String selectedItem = adapter.getItem(position).toString();
}

how to get the saved items for a particular listitem in android?

I am developing an application in which when user clicks on a item of a listview, a new page appears and in this page only the selected items are displayed. I mean for a particular list item only previously saved items are displayed.
In this new page i have 3 checkboxes. So when user clicks on a particular list item the new page display the checkbox with previous saved state for that particular item.
Now I dont know how to do that.
thanx in advance!!
This is my list onItemClick :-
OnItemClickListener ocl= new OnItemClickListener()
{
#Override
public void onItemClick(AdapterView<?> arg0, View arg1,
int arg2, long arg3)
{
String name= list.get(arg2)[2];
Toast.makeText(Profile.this, "session of.." + name, Toast.LENGTH_LONG).show();
Settings.setName(name);
Intent intent= new Intent(Profile.this, ProfileConfig.class);
startActivity(intent);
}
};
lvChildProfile.setOnItemClickListener(ocl);
Now i want that when clicking the saved instance of checkbox appear.

You can keep the state within your objects itself.
Model implements Serializable {
boolean isOptionOneChecked
boolean isOptionTwoChecked
boolean isOptionThreeChecked
int id
...
// Constructor
// Getters & setters
}
This means your Adapater will have a list of objects from the type Model. How you want to display these in your ListView, can be done with a custom Adapter but that's not the real question.
When you click on an Item in your list, you can retrieve the object (like you already did) with
Model lModel = list.get(position);
In order to display the Model in a different Activity, you can send it along with your Intent as such:
Intent intent= new Intent(Profile.this, ProfileConfig.class);
intent.putExtra("MySelectedObject", lModel);
startActivity(intent);
Because our class implements the Serializable interface, we can retrieve the object in our new Activity as followed:
getIntent().getSerializableExtra("MySelectedObject");
You will have all the information about this object so you can create you layout accordingly.

Passing Which ListView Item was Clicked to the Next Screen - Android

I have a ListView in Screen 1 where I have a few items . The User Clicks on an item in the Listview and Screen2 pops up . But What appears in Screen2 depends on what item was clicked in Screen 1
For Ex - User Clicks A in Screen 1 - Words starting from A come up in Screen 2
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, Open the Next Screen
Intent r=new Intent(Dummy.this ,CricksList.class );
r.putExtra("extra", id);
startActivityForResult(r, position);
}
I have passed the item which was clicked on . But I want to Display on Screen 2 what the user clicked on - as an item in the List View . How do I do that ??

Create another activity and put code like this in it.....
TextView textview = (TextView) findViewById(R.id.myEditText);
String Name = getIntent().getStringExtra("extra");
textview.setText(Name);

Use the extra field from the receiving intent, and based on that, lookup the record in your data source(database, contentprovider, array) and inflate a view that suit your needs.

Try to create the other activity which displays the clicked item. Then, call the second activity on click.
