I am trying to transfer my username value to a new activity. However when I do this it is displaying the first array item I have added, for example the code below displays "Bob Jones" for the username in the Conversation activity even if I click on a different item in the list.
public class MainActivity extends Activity {
TextView user;
TextView threadId;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//messaging_string = (TextView) findViewById(R.id.messaging_string);
//this.GetActivityFeedData();
final ListView listView = (ListView) this.findViewById(R.id.messagingListView);
final ActivityAdapter itemAdapter = new ActivityAdapter(getApplicationContext(), this.GetActivityFeedData());
listView.setAdapter(itemAdapter);
listView.setTextFilterEnabled(true);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
user = (TextView) findViewById(R.id.messaging_username);
threadId = (TextView) findViewById(R.id.messaging_threadId);
listView.getAdapter().getItem(position);
Intent intent = new Intent(MainActivity.this, ConversationView.class);
intent.putExtra("username", user.getText().toString());
intent.putExtra("pos", position);
intent.putExtra("threadId", threadId.getText().toString());
startActivity(intent);
}
});
}
public ArrayList<MessageItem> GetActivityFeedData() {
ArrayList<MessageItem> items = new ArrayList<MessageItem>();
items.add(new MessageItem(6, "Lorna Smith", "image", DateTime.now(), "Hello what are you doing"));
return items;
}
class ActivityFeedTask extends AsyncTask<Integer, Void, Void> {
ArrayList<MessageItem> recentTracks;
//remove to not loading more data
}
public class ActivityAdapter extends ArrayAdapter<MessageItem> {
private final Context context;
private final ArrayList<MessageItem> items;
private int currentPage = 0;
public ActivityAdapter(Context context, ArrayList<MessageItem> recentTrackArrayList) {
super(context, 0, recentTrackArrayList);
this.context = context;
this.items = recentTrackArrayList;
}
}
you have to fetch the content of the row you clicked. You can retrieve this object with parent.getItemAtPosition(position);,
MessageItem itemAtPostion = (MessageItem) parent.getItemAtPosition(position);
Intent intent = new Intent(MainActivity.this, ConversationView.class);
intent.putExtra("username", itemAtPostion.Username);
intent.putExtra("pos", position);
intent.putExtra("threadId", itemAtPostion.ThreadId);

I'm trying to use a Custom ListView Adapter to switch to different activities, but am having trouble doing so, as there is an error that I can't seem to get rid of.
Relevant code
Category Table:
public class CategoryTable extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.category_table);
populateTable();
goToPreviousActivity();
}
private void populateTable() {
final ListView mListView = findViewById(R.id.listView);
Category 1 = new Category(" One");
Category 2 = new Category(" Two");
Category 3 = new Category(" Three");
Category 4 = new Category(" Four");
final ArrayList<Category> categoryList = new ArrayList<>();
categoryList.add(1);
categoryList.add(2);
categoryList.add(3);
categoryList.add(4);
CategoryListAdapter adapter = new CategoryListAdapter(this, R.layout.adapter_view_layout, categoryList);
mListView.setAdapter(adapter);
}
private void goToPreviousActivity() {
ImageButton btn = findViewById(R.id.backButton);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
finish();
}
});
}
public static Intent makeIntent(Context context) {
return new Intent(context, CategoryTable.class);
}
}
Category List Adapter:
public class CategoryListAdapter extends ArrayAdapter<Category> {
private Context mContext;
int mResource;
public CategoryListAdapter(Context context, int resource, ArrayList<Category> objects) {
super(context, resource, objects);
mContext = context;
mResource = resource;
}
#NonNull
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
String name = getItem(position).getName();
Category category = new Category(name);
final LayoutInflater inflater = LayoutInflater.from(mContext);
convertView = inflater.inflate(mResource, parent, false);
Button catName = convertView.findViewById(R.id.btnNextTbl);
catName.setText(name);
catName.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (position == 0) {
//error -> makeIntent(android.content.Context in AllToolsTable cannot be applied to com.test.test.CategoryListAdapter
Intent intent = AllToolsTable.makeIntent(CategoryListAdapter.this);
mContext.startActivity(intent);
} else {
Toast toast = Toast.makeText(getContext(), "Clicked2", Toast.LENGTH_SHORT);
toast.show();
}
}
});
return convertView;
}
}
(I commented above the erroneous piece of code)
All Tools Table:
public class AllToolsTable extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.all_tools_table);
}
public static Intent makeIntent(Context context) {
return new Intent(context, AllToolsTable.class);
}
}
I will provide any other relevant code/details if needed.
Any help will be greatly appreciated.
//error -> makeIntent(android.content.Context in AllToolsTable cannot be applied to com.test.test.CategoryListAdapter
Intent intent = AllToolsTable.makeIntent(CategoryListAdapter.this);
Your AllToolsTable.makeIntent() method requires a Context argument. Normally you'd be fine with something like AllToolsTable.makeIntent(MainActivity.this) because Activity is a subclass of Context. However, CategoryListAdapter is not.
So you need to get your hands on a Context object somehow.
Luckily, the getView() method passes you a non-null ViewGroup parent object, and all views have a context. So you can replace your intent creation with this code:
Context context = parent.getContext();
Intent intent = AllToolsTable.makeIntent(context);
i have done custom listview
it has 6 textview and 1 image view in each row
whati did is when press on item it just goes to my second activity
but what it want is to pass the items of the row to the second activity
i don't know how to do it or where to add it in the list or in the adapter
also what to do in the second activity
here is my first activity
public class ImageListActivity extends AppCompatActivity {
private DatabaseReference mDatabaseRef;
private List<ImageUpload> imgList;
private ListView lv;
private ImageListAdapter adapter;
private ProgressDialog progressDialog;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_image_list);
imgList = new ArrayList<>();
lv = (ListView) findViewById(R.id.listViewImage);
//Show progress dialog during list image loading
progressDialog = new ProgressDialog(this);
progressDialog.setMessage("Please wait loading list image...");
progressDialog.show();
mDatabaseRef = FirebaseDatabase.getInstance().getReference(ListActivity.FB_Database_Path);
mDatabaseRef.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
progressDialog.dismiss();
//Fetch image data from firebase database
for (DataSnapshot snapshot : dataSnapshot.getChildren()) {
//ImageUpload class require default constructor
ImageUpload img = snapshot.getValue(ImageUpload.class);
imgList.add(img);
}
//Init adapter
adapter = new ImageListAdapter(ImageListActivity.this, R.layout.image_item, imgList);
//Set adapter for listview
lv.setAdapter(adapter);
}
#Override
public void onCancelled(DatabaseError databaseError) {
progressDialog.dismiss();
}
});
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent myintent = new Intent(view.getContext(), Buy1Activity.class);
startActivityForResult(myintent, 0);
}
});
}
}
and this is adapter
public class ImageListAdapter extends ArrayAdapter<ImageUpload> {
private Activity context;
private int resource;
private List<ImageUpload> listImage;
public ImageListAdapter(#NonNull Activity context, #LayoutRes int resource, #NonNull List<ImageUpload> objects) {
super(context, resource, objects);
this.context = context;
this.resource = resource;
listImage = objects;
}
#NonNull
#Override
public View getView(int position, #Nullable View convertView, #NonNull ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View v = inflater.inflate(resource, null);
TextView tvName = (TextView) v.findViewById(R.id.tvImageName);
TextView tvModel = (TextView) v.findViewById(R.id.tvImageModel);
TextView tvBrand = (TextView) v.findViewById(R.id.tvImageBrand);
TextView tvPrice = (TextView) v.findViewById(R.id.tvImagePrice);
TextView tvyear = (TextView) v.findViewById(R.id.tvImageYear);
TextView tvDesc = (TextView) v.findViewById(R.id.tvImageDesc);
ImageView img = (ImageView) v.findViewById(R.id.imgView);
tvModel.setText(listImage.get(position).getModel());
tvName.setText(listImage.get(position).getName());
tvBrand.setText(listImage.get(position).getBrand());
tvyear.setText(listImage.get(position).getYear());
tvDesc.setText(listImage.get(position).getDesc());
tvPrice.setText(listImage.get(position).getPrice());
Glide.with(context).load(listImage.get(position).getUrl()).into(img);
return v;
}
}
What I understand, you want to transfer the entire object namely ImageUpload of the list item you clicked on. For this you can create ImageUpload model class as Parcelable and and then pass selected ImageUpload object in your intent and retrieve it back from Intent using getParcelable().
on list item click:
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent myintent = new Intent(view.getContext(), Buy1Activity.class);
myintent.putExtra("selected_image_upload", ((ImageUpload) adapter.getItem(position)));
startActivityForResult(myintent, 0);
}
});
on Buy1Activity, to get the selected ImageUpload object in onCreate():
ImageUpload imgUploadObj = getIntent().getExtras().getParcelable("selected_image_upload");
You can get hint from here to create a class Parcelable.
Try this
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
ImageUpload img = adapter.get(position);
Intent myintent = new Intent(view.getContext(), Buy1Activity.class);
myintent.putParcelableArrayListExtra("parcel_data", img);
startActivityForResult(myintent, 0);
}
});
In your Buy1Activity
#Override
protected void onCreate(Bundle savedInstanceState) {
ImageUpload img = (ImageUpload) getIntent().getParcelableArrayListExtra("parcel_data");
}
Hope it help!
My ListView has set of rows with Delete Button in each row.
On Click of the delete button must delete particular row from Sqlite Database and refresh the listview.
Problem
I am able to delete row from database. But I am not able to refresh the page after deleting the row.
For refreshing I tried using notifyDatasetChanged(), but no luck.
I could able to see the new list if i got back to previous activity and come back to same activity.
Please find the adapter and class codes below.

Any Help would be really helpfull.
Thanks.
you are just deleting a row from database. Your adapter is still having the same set of data. So first update the data set of the adapter and than call notifydatasetchanged()
Hi I want to add an item to a listview.
This is my New message activity in which I wan to pass an item to my Main Activity. I'm not quite sure how to pass this data through an intent any help would be greatly appreciated.
public class NewMessage extends ActionBarActivity {
EditText new_message;
Button post_new_message_button;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_new_message);
new_message = (EditText) findViewById(R.id.message_content);
post_new_message_button = (Button) findViewById(R.id.message_send);
post_new_message_button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
TextView username = (TextView) findViewById(R.id.conversation_username2);
itemAdapter.add(new MessageItem(1656,"Bill Smith", "image", DateTime.now(), new_message.getText().toString()));
itemAdapter.notifyDataSetChanged();
if (v.getId() == R.id.message_send);
new_message.setText("");
}
});
}
}
This is my main activity I want to pass in the data
public class MainActivity extends ActionBarActivity {

if (items.get(position).Image == null) {
comment3.setImageResource(R.drawable.ic_launcher);
}
TextView comment4 = (TextView) rowView

}
return convertView;
}
}
}
if you just want to pass data back and forth between the two activities, maybe you should use:
startActivityForResult(Intent intent, int requestCode)
and
onActivityResult(int requestCode, int resultCode, Intent data)
So that when the NewMessageActivity finishes, it can send the data back to the main activity.
Hi i am writing a program using custom listview with checkbox. My intention is to start a new activity when clicking a button (Add) and the new activity displays the selected values from the listview.I am getting error when i try to add the values

thanks in advance..
initialize the "ArrayList"
ArrayList<List> selectedItems;

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home_page);
selectedItems = new ArrayList<List>();
}
