It looks like you are already starting an activity when the submit button is clicked. Now all you have to do is pass a couple extras in the intent you are creating.
So when you make the intent you should also do this:
...
Intent i = new Intent(v.getContext(), ReceiptActivity.class);
i.putExtra("PRICE", price);
i.putExtra("MEMBERSHIP", membership);
i.putExtra("ITEM", item);
startActivity(i);
...
Then in your new activity you will read out the extras in your onCreate method like this:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_receipt);
int price = getIntent().getStringExtra("PRICE");
String membership = getIntent().getStringExtra("MEMBERSHIP");
CustomItem item = getIntent().getStringExtra("ITEM");
...
One Caveat! It looks like you are representing your items with the object CustomItem. In order to pass that as an extra it will have to implement Parcelable. When you implement Parcelable you will define how to turn the object and its fields into a "parcel" and how to turn a "parcel" back into your object. The google docs give a pretty good example for it.
I lied, another caveat! I would recommend that you make the keys for the extras "public static final String"s inside of your ReceiptActivity. That way you will have an easier time managing them.

I get data in JSON from API, and there are id and url. Now, i need to create a button "Add to favorites" for each image that i display. When i try to set adapter.setListener(this);, i get an error, because i can't use string format.
How can i resolve this problem? I spend 5 hours on this, and can't resolve it :(

I display the id that i receive from server for each item, it's ok, but i don't know how to set the button "add to favorites" to works fine. It must receive item id (that i received from server) as a param, but id is in string format.
final String id = catDetails.getId();
change it to
final String id = Integer.toString(catDetails.getId());
I am working on an Activity which is a search page. It contains some values with edittext and spinner.

I am creating app like e-commerce with listview that containing images, textbox and one checkbox. Now my question is that, i want send cheched item with their hole to serve on onClickListener.Before send it to server, I will pass it to next activity and this activity contains one application form where user can fill form after completion filling form when user click on button all user info and checked item data send to server database. I don't know how to pass checked item data to server. And one more main thing is that my listview data is retrieve from server using json and php. so please send me code or links that i can use for to do this things. Thank You

The code below works fine. It populates a list with values from a JSON response and will open a new activity on selection of any of the items, as well as displaying the number of the item.
My question is how to have the selected item open an activity with the specific information from that item. Example: I select "Bob" from the List, I am taken to a new activity with the name of Bob, his email, and his phone. Or any other values that the JSON might have sent. If I select "George" it will do the same, but with the details for George.
I attempted unsuccessfully to do this on my own. Any help is appreciated.

CustomListAdapter.java code:
public class CustomListAdapter extends BaseAdapter {
public Activity activity;
private LayoutInflater inflater;
private List<LoadUsers> usersItems;
ImageLoader imageLoader = AppController.getInstance().getImageLoader();
public CustomListAdapter(Activity activity, List<LoadUsers> usersItems) {

if (convertView == null)
convertView = inflater.inflate(R.layout.list_row, null);
if (imageLoader == null)
imageLoader = AppController.getInstance().getImageLoader();
NetworkImageView thumbNail = (NetworkImageView) convertView.findViewById(R.id.thumbnail);
TextView title = (TextView) convertView.findViewById(R.id.title);
TextView email = (TextView) convertView.findViewById(R.id.lvemail);
TextView phone = (TextView) convertView.findViewById(R.id.lvphone);
// getting user data for the row

// thumbnail image
thumbNail.setImageUrl(m.getThumbnailUrl(), imageLoader);
// title
title.setText(m.getTitle());
// email
email.setText("Email: " + String.valueOf(m.getEmail()));
// phone
phone.setText("Phone: " + String.valueOf(m.getPhone()));
return convertView;
}
}
New Activity that is being opened on selection of item:
onDetailsSelect.java:
public class onDetailsSelect extends AppCompatActivity {
Toolbar toolbar;
ActionBarDrawerToggle mActionBarDrawerToggle;
DrawerLayout drawerLayout;
private TextView title, email, phone;
private List<LoadUsers> usersItems;
ImageLoader imageLoader = AppController.getInstance().getImageLoader();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_onuserselect);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
NetworkImageView thumbNail = (NetworkImageView) findViewById(R.id.thumbnail);
title = (TextView) findViewById(R.id.title);
email = (TextView) findViewById(R.id.lvemail);
phone = (TextView) findViewById(R.id.lvphone);
}
}
Modify your onItemClick like that:
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(this, "Item Clicked: " + position, Toast.LENGTH_SHORT).show();
TextView title = (TextView) view.findViewById(R.id.title);
String title_text = title.getText().toString();
TextView email = (TextView) view.findViewById(R.id.lvemail);
String email_text = email.getText().toString();
TextView phone = (TextView) view.findViewById(R.id.lvphone);
String phone_text = phone.getText().toString();
Intent i = new Intent(Details.this, onDetailsSelect.class);
i.putExtra("title_intent", title_text);
i.putExtra("email_intent", email_text);
i.putExtra("phone_intent", phone_text);
startActivity(i);
}
And retrieve the intent values in onDetailsSelect Activity, in onCreate:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.detail);
Intent i = getIntent();
String title = i.getStringExtra("title_intent");
String email = i.getStringExtra("email_intent");
String phone = i.getStringExtra("phone_intent");
}
You can pass your ArrayList and item position on which you have clicked in the ListView, to the new activity like this --
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
String item_position = String.valueOf(position);
ArrayList<ListRowItem> full_listitem = listitem;
Intent intent = new Intent(context,SecondActivity.class);
Bundle extras = new Bundle();
extras.putString(CRRNT_ROW_NUMBER, item_position);
extras.putSerializable(LISTITEM, full_listitem);
intent.putExtras(extras);
startActivity(intent);
}
});
In your 2nd Activity, you have to receive these using the below code --
Intent intent = getIntent();
Bundle extras = intent.getExtras();
item_position = extras.getString(FirstActivity.CRRNT_ROW_NUMBER);
listitem = (ArrayList<ListRowItem>)extras.getSerializable(FirstActivity.LISTITEM);
position = Integer.parseInt(item_position);
currentlistitem = listitem.get(position);
String a = currentlistitem.getA();
String b = currentlistitem.getB();
For all these implementations, you have to implement Serializable interface in both your Activities and also in the LoadUsers (Getter/Setter) class.
Hope this helps!
I have a list view with two buttons edit and delete.On click of these buttons I either update or delete the items in the list view from my custom adapter.But the problem is if I add a new item to the list my previous changes are discarded and old values are displayed.
The following is my code for the adapter.
public class RoleList extends ArrayAdapter<String>
{
private ArrayList<String> name;
private ArrayList<String> username;
private ArrayList<String> password;
private ArrayList<String> role;
private Activity context;
public RoleList(Activity context, ArrayList<String> name, ArrayList<String> username, ArrayList<String> password, ArrayList<String> role)
{
super(context, R.layout.role_list,name);
this.context = context;
this.name = name;
this.username =username;
this.password = password;
this.role = role;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent)
{
LayoutInflater inflater = context.getLayoutInflater();
final View listViewItem = inflater.inflate(R.layout.role_list, null, true);
final TextView textViewName = (TextView) listViewItem.findViewById(R.id.tv_empname);
final TextView textViewusername = (TextView) listViewItem.findViewById(R.id.tv_empusername);
final TextView textViewPass = (TextView) listViewItem.findViewById(R.id.tv_emppassword);
final TextView textViewRole = (TextView) listViewItem.findViewById(R.id.tv_emprole);
Button edit = (Button) listViewItem.findViewById(R.id.btn_editRole);
Button delete = (Button) listViewItem.findViewById(R.id.btn_delRole);
delete.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v)
{
name.remove(position);
username.remove(position);
password.remove(position);
role.remove(position);
notifyDataSetChanged();
}
});
edit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v)
{
Log.d("Emp Info", name.get(position) + " " + username.get(position) + " " + password.get(position) + " " + role.get(position));
final Dialog dialog = new Dialog(getContext());
dialog.setContentView(R.layout.userreg);
dialog.setTitle("Edit Employee " + name.get(position) + " details");
final String[] arraySpinner = new String[]{"Manager","Stockist","Cashier","Accountant"};
dialog.setCancelable(false);
dialog.setCanceledOnTouchOutside(false);
final EditText emp_name = (EditText) dialog.findViewById(R.id.editTextName);
final EditText emp_uname = (EditText) dialog.findViewById(R.id.editTextUserName);
final EditText emp_pw = (EditText) dialog.findViewById(R.id.editTextPassword);
final Spinner emp_role = (Spinner) dialog.findViewById(R.id.spinner_role);
final TextView textRole = (TextView) dialog.findViewById(R.id.tv_selected_role);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getContext(),android.R.layout.simple_spinner_item, arraySpinner);
emp_role.setAdapter(adapter);
emp_role.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(getContext(), "Role Selected is " + arraySpinner[position], Toast.LENGTH_SHORT).show();
String employee_role = arraySpinner[position];
textRole.setText(employee_role);
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
emp_name.setText(name.get(position));
emp_uname.setText(username.get(position));
emp_pw.setText(password.get(position));
emp_role.setSelection(position);
Button buttoncancel = (Button) dialog.findViewById(R.id.buttonCancel);
buttoncancel.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
Button buttonChange = (Button) dialog.findViewById(R.id.buttonRegister);
buttonChange.setText("Change");
buttonChange.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v)
{
textViewName.setText(emp_name.getText().toString());
textViewusername.setText(emp_uname.getText().toString());
textViewPass.setText(emp_pw.getText().toString());
textViewRole.setText(textRole.getText());
dialog.dismiss();
}
});
dialog.show();
}
});
textViewName.setText(name.get(position));
textViewusername.setText(username.get(position));
textViewPass.setText(password.get(position));
textViewRole.setText(role.get(position));
return listViewItem;
}
}
The following is the code inside the activity for the Handler class.
public void userRolehandler()
{
final Handler handler = new Handler();
handler.post(new Runnable() {
#Override
public void run()
{
RoleList roleList = new RoleList(UserRegistration.this,employee_name,emp_username,emp_password,employee_role);
Log.d("ARRAY SIZE", String.valueOf(employee_name.size()));
userList.setAdapter(roleList);
roleList.notifyDataSetChanged();
}
});
}
Code for constructing the json array.
public void userRoleArray() throws JSONException {
name = editTextName.getText().toString();
username = editTextUsername.getText().toString();
password = editTextPassword.getText().toString();
emp_role = textRole.getText().toString();
JSONObject jsonobj = new JSONObject();
jsonobj.put("name",name);
jsonobj.put("username",username);
jsonobj.put("password",password);
jsonobj.put("emp_role",emp_role);
rolejson.put(counter,jsonobj);
counter++;
}
Code for Parsing the array.
public void travRoleArray() throws JSONException {
response = "{\"result\":" + rolejson.toString() + "}";
Log.d("RESPONSE",response);
JSONObject jsonOb = new JSONObject(response);
JSONArray result = jsonOb.getJSONArray(JSON_ARRAY);
try
{
employee_name.clear();
emp_username.clear();
emp_password.clear();
employee_role.clear();
for (int i=0; i< result.length();i++)
{
JSONObject jObj = result.getJSONObject(i);
employee_name.add(i,jObj.getString(KEY_NAME));
emp_username.add(i, jObj.getString(KEY_UNAME));
emp_password.add(i, jObj.getString(KEY_PASS));
employee_role.add(i,jObj.getString(KEY_ROLE));
}
for (String name:employee_name)
{
Log.i("Name : ",name);
}
}catch (ArrayIndexOutOfBoundsException e)
{
Toast.makeText(UserRegistration.this, "Array Index out of bound exception", Toast.LENGTH_LONG).show();
}
}
The problem is that the array list gets updated or deleted inside the
adapter class but the json array inside the activity still has the old
values.I would like to know how can I update the activity from the
adapter so that the json array has the updated values?
Any help or suggestion is appreciated.Thank you.
