I've looked and looked. Tried many things but nothing returns the data (regardless that it's present)
The information is being passed as: -> NOTE I posted wrong snippet, see below
userLists.setOnItemClickListener(new AdapterView.OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int pos, long arg3) {
Intent DisplayItems = new Intent(getApplicationContext(), Items.class);
Map<String,String> storeMap = lst.get(pos);
DisplayItems.putExtra("id", storeMap.get("id"));
startActivityForResult(DisplayItems, 1);
}
});
Received in onCreate:
groupIntent = getIntent();
if(groupIntent.hasExtra("groupid")) {
groupId = groupIntent.getStringExtra("groupid");
resultCode = 2;
}
groupId always returns null. In the debug groupIntent -> mExtras -> mMap -> value[0] = 5c00a086d45213.24138362 is displayed. All other classes pass and receive the intent as intended..
EDIT: My bad.. This is what actually inserts the extra
public void btnCreateList_Click(View view) {
Intent createList = new Intent(context, CreateList.class);
if(groupId!=null) {
String grp = groupId;
createList.putExtra("groupid", grp);
}
startActivityForResult(createList, 1);
}
The code should be like below:
groupIntent = getIntent();
if(groupIntent.hasExtra("id")) {
groupId = groupIntent.getStringExtra("id");
resultCode = 2;
}

I want to send int parameter in intent like this:
String textname = (String) dataItem.get("name");
Intent m = new Intent(list.this,main.class);
m.putExtra("name",textname);
m.putExtra("page",1);
startActivity(m);
and in main class I get that parameter
Intent intent = getIntent();
name = intent.getStringExtra("name");
page1 = Integer.parseInt(intent.getStringExtra("page"));
but when I run my code it force closes!!!
You should use getIntent().getIntExtra(name, defaultValue) instead of Integer.parseInt(intent.getStringExtra("page"));
Update:
int defaultValue = -1;// take any default value of your choice
String name = intent.getStringExtra("name");
int page1 = intent.getIntExtra("page", defaultValue);
I in other class use the main class and send parameter to it and it work without any problem but just in list class i have problem
in other class i like this send parameter
protected void onListItemClick(ListView l, View v, int position, long id) {
Intent i = new Intent(list_sub.this,main.class);
i.putExtra("name", Name[position]);
i.putExtra("page", Ted[position]);
startActivity(i);
}
and in refresh class i get ted parameter
private void refresh(){
db.open();
int s = db.List_count("text", ID);
Name= new String[s];
Ted=new String[s];
for(int i=0;i<s;i++){
Name[i]=db.List_display_sub("text", ID, i);
Ted[i]=db.page_count("text", Name[i].toString())+"";
}
db.close();
}
Activity A
String textname = (String) dataItem.get("name");
Intent m = new Intent(list.this,main.class);
m.putExtra("name",textname);
m.putExtra("page",1);
startActivity(m);
Activity B
Intent intent = getIntent();
name = intent.getStringExtra("name");
int page = intent.getIntExtra("page", 0);
where 0 is the default value.
I have a list view which contains a TextView for each list item. I need to take a picture onItemClick of the listView. onActivityResult of the ACTION_IMAGE_CAPTURE intent and updating the listview , I start another activity for result.
The problem I am facing is that all the textviews in my list view are getting reset when I come back to the activity onActivityResult from the second activity. Can you please help me with this.
This is my onItemClick
public void onItemClick(AdapterView<?> arg0, View v, int index, long arg3) {
selectedIndex = index; //selectedIndex is a class level variable
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = createImageFile();
if (f != null) {
imageFileName = f.getAbsolutePath();
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
}
startActivityForResult(takePictureIntent, 1);
}
}
This is my onActivityResult
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1 && resultCode == RESULT_OK) {
View v = listView.getChildAt(selectedIndex
- listView.getFirstVisiblePosition());
TextView textView = (TextView) v.findViewById(R.id.textView1);
int quantity = Integer
.parseInt(textView.getText().toString().trim().length() > 0 ? quantityTV
.getText().toString() : getString(R.string._0));
quantity++;
textView.setText(String.valueOf(quantity));
listViewAdapter.notifyDataSetChanged();
Intent intent = new Intent();
intent.setClass(getApplicationContext(), NotificationActivity.class);
intent.putExtra("Value1", "0");
startActivityForResult(intent, 100);
}
else if (requestCode == 100) {
// do nothing
}
}
While you're updating the content of the text view here, you're not updating the data that backs the adapter for your list view. This means when your activity comes back into view (after the second startActivityForResult) it's redrawing itself with the old data.
Instead of updating the view directly, you should update the data that backs the adapter. Something like this; you'll have to modify it to suit your code.
if (requestCode == 1 && resultCode == RESULT_OK) {
List<Integer> adapterData = listViewAdapter.getQuantities();
int quantity = adapterData.get(selectedIndex) + 1;
adapterData.set(selectedIndex, quantity);
listViewAdapter.setQuantities(adapterData);
Intent intent = new Intent();
intent.setClass(getApplicationContext(), NotificationActivity.class);
intent.putExtra("Value1", "0");
startActivityForResult(intent, 100);
}
And in your adapter, you'd have something like this:
public List<Integer> getQuantities() {
return mQuantities;
}
public void setQuantities(List<Integer> quantities) {
mQuantities = quantities;
notifyDataSetChanged();
}
I am using .net web services. I am trying to get list in ListView. Right now it is showing me the first list, but when I am trying to get it again using the same method it is giving me a response in log but not displaying in list.
I have used mAdapter.notifyDataSetChanged(); in my Adapter but it's not working. Please help. thanks

Use like this list();.
Call this method from Where do you want.
I have some trouble with putExtras to an intent. Could you please review my code?
public void onSelectCategory(View v) {
int category = Integer.parseInt((String) v.getTag());
Intent intent = new Intent(HomeActivity.this, ListActivity.class);
intent.putExtra("EXT_CATEGORY", category);
startActivity(intent);
}
And in the ListActivity, I'm doing the following..
public static final String EXT_CATEGORY = "category";
int category = getIntent().getExtras().getInt(EXT_CATEGORY);
From this line
intent.putExtra("EXT_CATEGORY", category);
in your another activity String name should be same means:--
public static final String EXT_CATEGORY = "EXT_CATEGORY";
You did several mistakes, here is a overworker version of your code.
public void onSelectCategory(View v) {
int category = Integer.parseInt((String) v.getTag());
Intent intent = new Intent(HomeActivity.this, ListActivity.class);
intent.putExtra(EXT_CATEGORY, category);
startActivity(intent);
}
int defaultCat = -1;
public static final String EXT_CATEGORY = "category";
int category = getIntent().getIntExtra(EXT_CATEGORY,defaultCat); // Use default int if there is no extra
You should use this to get you info, not getExtras() :
int category = getIntent().getIntExtra("EXT_CATEGORY");
getExtras() returns additional Bundle of data. You need only one integer.

A wiser move, might be passing the id of that database row to the next Activity.
And your code is incomplete, but it looks like only the last row's data will ever be passed to the next activity.
Also, it might be mildly more efficient and clear if you just putExtra directly into the intent instead of the intermediary Bundle.
Good practices said to include the package name as a prefix in the extra names.
