I'm trying to build an Attendance Manager app for students and am using a custom ListView to display subject names and minimum attendance when tapped on.
These are the Issues I'm facing::
1) I want my first list item to be an "Add a subject item" and on tapping on that it goes to AddSubjectActivity and stores everything via SharedPreferences.
2)Once the submit button is pressed in the AddSubjectActivity i want the next list item to say "Tap to add a subject" and so on.
3) Basically ,suppose the ListView has 5 items, tapping on each item takes me to the AddSubject Activity, but information corresponding to the respective list Item being tapped is displayed in it.
This is my Code:
Class CustomAdapter
public class CustomAdapter extends BaseAdapter{
String [] result;
Context context;
int [] imageId;
private static LayoutInflater inflater=null;
public CustomAdapter(SecondActivity mainActivity, String[] prgmNameList, int[] prgmImages) {
// TODO Auto-generated constructor stub
result=prgmNameList;
context=mainActivity;
imageId=prgmImages;
inflater = ( LayoutInflater )context.
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return result.length;
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return position;
}
#Override

// TODO Auto-generated method stub
return position;
}
public class Holder
{

ImageView img;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
Holder holder=new Holder();
SecondActivity second=new SecondActivity();
View rowView;
rowView = inflater.inflate(R.layout.program_list, null);
holder.tv=(TextView) rowView.findViewById(R.id.textView);
holder.img=(ImageView) rowView.findViewById(R.id.statsImageView);
holder.tv.setText(result[position]);
holder.img.setImageResource(imageId[position]);
rowView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v)
{
// TODO Auto-generated method stub
Toast.makeText(context, "You Clicked "+result[position], Toast.LENGTH_LONG).show();

You can't remove anything from an array - they're always fixed length. Once you've created an array of length 3, that array will always have length 3. And if you want to delete from the listview the array which you are used should be dynamic(Adding & Deleting). So make the pIdz; pNamz;pPrizs;userData into some Modal Object, and prepare the list of Modal Objects and pass it to adapter and make the life easier
You'd be better off with a List, e.g. an ArrayList:
hldr.delete.setTag(position);
hldr.delete.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
int position = (int)v.getTag();
list.remove(position);
notifyDataSetChanged();
}
});
First.
You should make a object that stores all your different strings instead of using multiple arrays for each value.
Ej:
class MyClass
{
String id;
String name
String price;
public MyClass(String id, String name, String price)
{
this.id = id;
this.name = name;
this.price = price;
}
}
That way you wouldnt have to delete the position of each of the arrays.
And finally to answer your question, just delete the value of position you want to delete for each of the arrays.
Since they are Array and not ArrayList you will need to recreate it with the correct new dimension (Note it will be much easier with ArrayList).
Then just call notifyDataSetChanged() on your Adapter class.
Hope this helps.
This is my custom list adapter. I want to update the values in table using the update ImageButton in the list. On clicking it, the old values should be shown in a new activity and then the edited value must be stored in the database. However, I am unable to pass an intent inside the onClick() method.
Please suggest me a solution

}
//Handle TextView and display string from your list

listItemText.setText(list.get(position));
//Handle buttons and add onClickListeners

}
I suggest you to assign and ContextMenu to your list view with two MenuItem, Edit and Delete and write associated code outside of adapter
or you can start Activity by :
Intent new_intent = new Intent(v.getRootView().getContext(),edit_activity.class);
new_intent.putExtra("Key","Value");
v.getRootView().getContext().startActivity(new_intent);
i think the first method is best ;)
I have a customdialog box ,in this i have a listview and a spinner item.The listview contains textview and a radio button in each row.I can select only one row at a time with the help of radio buttons.This is happening.
Problem is coming when i select spinner items and then i select radio button ,the previous radio button is still selected.Now what i want when i select spinner items ,the previously selected radiobuttons should be unchecked.
Note:my spinner is in Main class and radio button is in CustomAdapterClass which i am calling in my Main class
Here is my code: Adapter Class:
public class APTRequestCustomAdapter extends BaseAdapter{

}
});
if (position==getCount()-1 && userSelected==false) {
// radio.setChecked(true);
mCurrentlyCheckedRB = radio;
} else {
radio.setChecked(false);
}
if(APTRequestCustomitems.get(position).getAppointmentstatus().equals("1")){
remove.setVisibility(View.INVISIBLE);

return;
mCurrentlyCheckedRB.setChecked(false);
((RadioButton) v).setChecked(true);
mCurrentlyCheckedRB = (RadioButton) v;
}
});
}
return v;
}
}
And this is the code where i am calling the adapter class:
This method is in Async Class on PostExecute()method

APTRequestCustomAdapter.mCurrentlyCheckedRB.setChecked(false);//this line of code is not executing,the radio button remains checked in the view
if(APTRequestCustomAdapter.mCurrentlyCheckedRB.isChecked()){// this lines of codes are not executing even though the radio button is checked ,i don't know why
APTRequestCustomAdapter.mCurrentlyCheckedRB.setChecked(false);// And this line is also not executing
}
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
APTRequestCustomAdapter adap=new APTRequestCustomAdapter(context,run_custom_universal_apptdata());
listcustomuniversalappt.setAdapter(adap);
/*//runapptstatus_method();
listcustomuniversalappt.setChoiceMode(1);
/
dialog.show();
}
Try to use your Custom Adapter like,
public class MyRadioAdapter extends BaseAdapter
{
private Context mContext;
private ArrayList<Variation> mVariations;
private int mSelectedVariation;
public MyRadioAdapter(Context context, ArrayList<Variation> variations, int selectedVariation)
{
mContext = context;
mVariations = variations;
mSelectedVariation = selectedVariation;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent)
{
View view = convertView;
if(view==null)
{
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.my_radio_adapter_item, null);
}
final Variation variation = mVariations.get(position);
TextView name = (TextView) view.findViewById(R.id.name);
RadioButton radio = (RadioButton) view.findViewById(R.id.radio);
name.setText(variation.getName());
if(position==mSelectedVariation) radio.setChecked(true);
else radio.setChecked(false);
view.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View v)
{
mSelectedVariation = position;
MyRadioAdapter.this.notifyDataSetChanged();
}
});
return view;
}
here Radio buttons are usually grouped by Radio Group.When one RadioButton within a group is selected, all others are automatically deselected.
am having a two editbox. the values enter in that has to placed in the custom listview its working fine for this...
but i want to save this values in the list view permanently.so that if the phones switches off and again run the app then the values have to be saved ..like phone contact number and name have to be saved..
here am ataching the code

}
}
use can use SharedPreferences, that will save your values permanently, untill they are changed(by changing values in editbox) or user reinstall (clear data) application. Shared Preferences works like this
// save string in sharedPreferences
SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
SharedPreferences.Editor editor = settings.edit();
editor.putString("some_key", string); // here string is the value you want to save
editor.commit();
// restore string in sharedPreferences
SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
string = settings.getString("some_key", "");
I would like to enable search functionality to EditText. My requirement is like this:
when someone types with some letter, suppose the user types 'a', then it should show all the words which starts with 'a' should be shown as a drop down list. For example, if I first typed "copy" in the EditText, if again, I cleared the EditText and tried to type "co", then it should show the drop-down list "copy","come","cow"....
I want to enable this feature to my EditText view. It worked when I had a ListView with only a textview inside, but now that I have two textview in my ListView it doesn't work.
This is my activity:
public class sedactivity extends Activity {
ListView lview;
ListViewAdapter lviewAdapter;
EditText ed;
private static final String first[] = {
"America",
"Busta",
"Cactus",
"Fire",
"Garden",
"Hollywood",
"King",};
private static final String second[] = {
"Uniti",
"Chiusa",
"Verde",
"Fiamme",
"Aperto",
"Boulevard",
"Kong",};
private ArrayList<String> arr_sort= new ArrayList<String>();
int textlength=0;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ed = (EditText)findViewById(R.id.EditText1);
lview = (ListView) findViewById(R.id.listView2);
lviewAdapter = new ListViewAdapter(this, first, second);
System.out.println("adapter => "+lviewAdapter.getCount());
lview.setAdapter(lviewAdapter);
lview.setTextFilterEnabled(true);
ed.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {
}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
public void onTextChanged(CharSequence s, int start, int before, int count) {
textlength=ed.getText().length();
arr_sort.clear();
for(int i=0;i<first.length;i++)
{
if(textlength<=first[i].length())
{
if(ed.getText().toString().equalsIgnoreCase((String) first[i].subSequence(0, textlength)))
{
arr_sort.add(first[i]);
}
}
}
}});}
}
And this is my ListView Adapter
public class ListViewAdapter extends BaseAdapter{
Activity context;
String title[];
String description[];
public ListViewAdapter(Activity context, String[] title, String[] description) {
super();
this.context = context;
this.title = title;
this.description = description;
}
public int getCount() {
// TODO Auto-generated method stub
return title.length;
}
public Object getItem(int position) {
// TODO Auto-generated method stub
return null;
}
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
private class ViewHolder {
TextView txtViewTitle;
TextView txtViewDescription;
}
public View getView(int position, View convertView, ViewGroup parent)
{
// TODO Auto-generated method stub
ViewHolder holder;
LayoutInflater inflater = context.getLayoutInflater();
if (convertView == null)
{
convertView = inflater.inflate(R.layout.listitem_row, null);
holder = new ViewHolder();
holder.txtViewTitle = (TextView) convertView.findViewById(R.id.textView1);
holder.txtViewDescription = (TextView) convertView.findViewById(R.id.textView2);
convertView.setTag(holder);
}
else
{
holder = (ViewHolder) convertView.getTag();
}
holder.txtViewTitle.setText(title[position]);
holder.txtViewDescription.setText(description[position]);
return convertView;
}
}
I think an AutoCompleteTextView might be more suitable to implement this feature.
Check out this example to create your own Listener to check the values inside Edittext on key press event - How to implement your own Listener
Instead of extending BaseAdapter you extend ArrayAdapter. It implements the Filterable interface for you. In TextWatcher call getFilter().filter(text); method.
public void afterTextChanged(Editable s) {
listview.getAdapter().getFilter().filter(s);
}
