ListView with MyAdapter that contains two TextViews and CheckBox

ListView with MyAdapter that contains two TextViews and CheckBox - android

I have a problem syncing the list items isChecked state with the checkboxes that in the same raw. I am able to set the 'checked' state in list items but can't figure how to set the 'checked' state of the CheckBoxes. I thought mainListView.setItemChecked should do the work but it doesn't.
This is the code i'm using:
public class Reservation_Activity extends ListActivity {
int total=0;
private name_price[] lv_arr = {};
private ListView mainListView = null;
final String SETTING_TODOLIST = "todolist";
TextView total_tv;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.reservation);
total_tv = (TextView) findViewById(R.id.total_sum);
Button btnSave = (Button) findViewById(R.id.btnSave);
btnSave.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(),
" You clicked Save button", Toast.LENGTH_SHORT).show();
}
});
Button btnClear = (Button) findViewById(R.id.btnClear);
btnClear.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
total=0;
total_tv.setText("Pick and Send");
Toast.makeText(getApplicationContext(),
" You clicked Clear button", Toast.LENGTH_SHORT).show();
ClearSelections();
}
});
// Prepare an ArrayList of todo items
ArrayList<name_price> listTODO = PrepareListFromXml();
this.mainListView = getListView();
mainListView.setCacheColorHint(0);
// Bind the data with the list
lv_arr = (name_price[]) listTODO.toArray(lv_arr);
mainListView.setAdapter(new MyAdapter(this,android.R.layout.simple_list_item_multiple_choice,lv_arr));
mainListView.setItemsCanFocus(false);
mainListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
mainListView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,long arg3) {
name_price item = (name_price) mainListView.getItemAtPosition(position);
if(mainListView.isItemChecked(position))
{
mainListView.setItemChecked(position, false);
total = total - item._price;
} else {
mainListView.setItemChecked(position, true);
total += item._price;
}
total_tv.setText("Total: " + total);
}
});
}
private void ClearSelections() {
total=0;
// user has clicked clear button so uncheck all the items
int count = this.mainListView.getAdapter().getCount();
for (int i = 0; i < count; i++) {
this.mainListView.setItemChecked(i, false);
}
}
private ArrayList<name_price> PrepareListFromXml() {
ArrayList<name_price> todoItems = new ArrayList<name_price>();
XmlResourceParser todolistXml = getResources().getXml(R.xml.order_items);
int id=0;
int eventType = -1;
while (eventType != XmlResourceParser.END_DOCUMENT) {
if (eventType == XmlResourceParser.START_TAG) {
String strNode = todolistXml.getName();
if (strNode.equals("item")) {
todoItems.add(new name_price(id,todolistXml.getAttributeValue(null, "title"), Integer.parseInt(todolistXml.getAttributeValue(null, "price"))));
id++;
}
}
try {
eventType = todolistXml.next();
} catch (XmlPullParserException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return todoItems;
}
public class MyAdapter extends ArrayAdapter<name_price> {
name_price[] items;
public MyAdapter(Context context, int textViewResourceId,
name_price[] objects) {
super(context, textViewResourceId, objects);
this.items = objects;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = getLayoutInflater();
View row = inflater.inflate(R.layout.list_raw_resevation, parent, false);
TextView name,price;
CheckBox ckbx = (CheckBox) row.findViewById(R.id.UpdateCheckBox);
ckbx.setChecked(mainListView.isItemChecked(position));
name = (TextView) row.findViewById(R.id.res_name);
name.setText(items[position]._name);
price = (TextView) row.findViewById(R.id.res_price);
price.setText(Integer.toString(items[position]._price));
return row;
}
public name_price getItem(int position) {
return items[position];
}
}
}
class name_price {
public String _name;
public int _price;
public int _id;
public CheckBox ckbx;
public name_price(int id, String name, int price)
{
this._id=id;
this._name = name;
this._price = price;
}
public name_price() {
// TODO Auto-generated constructor stub
}
}
I think I should change the checked state of the specific checkbox in mainListView.setOnItemClickListener according to this but I can't find a way to do it.
in addition, This is the raw layout and the list layout (of others to use):

RadioButton state and Button validation

I am facing two issues.
Radio buttons in radiogroup loosing state: when I click yes or no and scroll down the list view it looses the radiobutton value which is checked. I tried many ways to fix it but unable to achieve.
Submit button validation(Please refer image four): list of questions user should select either yes or no before clicking on submit button, if user click on submit button without selecting either yes or no it should them a toast message. all the questions should be selected with either yes or no. More specific each radiogroup should give me yes or no, not empty string.
Thanks in advance.

Try this.
Use ViewHolder so it does not lose the data set
Custom Adapter class
#Override

I want to get selected radio button position or value and id so that on button click I tried with but it always take first position. Can any one suggest me where am I doing wrong? I have to get selected radio button position so that I can get value from list of Objects. I have to send into next activity.

In adapter create a method which returns the object of selected position. Like :
public ListofAddressesDataModel getSelectedItem() {
return data.get(selectedPosition);
}
In activity, on click of the button call this method. Like :
#Override
public void onClick(View v) {
if(v.getId() == R.id.button) {
//Here you will get the selected item of which the radio button is checked
ListofAddressesDataModel selectedItem = ((ListofAddressesAdapter) add.getAdapter()).getSelectedItem();
}
}
EDIT :
Instead of below lines in getView() in adapter
holder.r.setTag(position);
holder.r.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
selectedPosition = (Integer) view.getTag();
name = data.get(selectedPosition).getName();
phone = data.get(selectedPosition).getPhone();
address = data.get(selectedPosition).getFulladdress();
customeraddressid = data.get(selectedPosition).getCustaddid();
notifyDataSetChanged();
}
});
just replace it with below line
holder.r.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
selectedPosition = position;
}
});

Button click event with Custom List view

I have two button at bottom i.e after listview ends.

TextView text = (TextView) view.findViewById(R.id.heading);
int no = position;
if(cmp.get(position).equals("GREEN"))
{
text.setTextColor(Color.parseColor("#00D50E"));
}else if(cmp.get(position).equals("RED"))
{
text.setTextColor(Color.parseColor("#e84040"));

{
text.setTextColor(Color.parseColor("#B441E9"));

((TextView) view.findViewById(R.id.duration)).setText(timeused.get(position));
return view;
//String.valueOf(value);
}
}

So these buttons are not part of your ListView? Well, than in your onCreate do something like:
solbtn = (Button)findViewById(R.id.solution);
solbth.setOnClickListener( toolbar.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
yourMethod();
}
});
And the same goes for the second button.
Or you can make your Activity implement View.OnClickListener, after doing this you can set your click listeners like this:
//this two lines in your OnCreate
button1.setOnClickListener(this);
button2.setOnClickListener(this);
//somewhere later in the code
#Override
public void onClick(View v) {
//do something
}

Just add the clickListeners in your onCrete() method:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
.....
solbtn = (Button) findViewById(R.id.home);
homebtn = (Button) findViewById(R.id.solution);
solbtn.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
// do stuff for solution button
}
});
homebtn.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
// do stuff for home button
}
});
.....
}

Get listitem from listview(Customized using Radio Button) when clicked on the Particular Item

I have prepared custom Listview in that i want to select one item from view so for that i have used RadioButton view for single choice item,but i customized it.Following is my total code ,because there may be error in the layout so please help me in solving this.

Update use code as per below
// On item click listener
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View view, int position,long itemId) {
RadioButton btn=(RadioButton) view.findViewById(R.id.startfromrb);
String sfrom = btn.getText().toString();
arrayAdapter.setSelected((int)itemId);
Log.i("STARTFROM", sfrom);
}
});
//Add below function in adapter class
public void setSelected(int selectedPosition){
this.selectedPosition=selectedPosition;
notifyDataSetChanged();
}
Also remove from adapter
rbStartFrom.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
selectedPosition = (Integer) v.getTag();
notifyDataSetInvalidated();
Log.i("IN ADAPTER", "" + selectedPosition);
}
});
And add android:clickable="false" and set selectedPosition to -1 by default

The first I see is, that You have to change the reference to the Views where You want to set the other views below :
<Spinner
android:id="#+id/spinner1"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<ListView
android:id="#+id/lstDemo"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_below="#+id/spinner1" <!-- correct: #id/spinner1 -->
android:layout_marginBottom="60dp" >
</ListView>
<TextView
android:id="#+id/emptytv"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/spinner1" <!-- correct: #id/spinner1 -->
android:layout_marginBottom="60dp"
android:gravity="center_vertical|center_horizontal"
android:text="No Records Found."
android:textSize="25sp" />
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_marginLeft="31dp"
android:text="Button" />
</RelativeLayout>
But anyway, Your TextView is sitten directly above the listView, is this Your intention? If not, You have to set
android:layout_below="#+id/lstDemo"
Also, if You get any errors, please post the logcat output. If You just have problems with Your layout, please explain clear enough what exactly You want.
EDIT
try to get the selected item String like this:
final String item = (String) parent.getItemAtPosition(position);
loadListView(item);

public class ImageAdapter extends BaseAdapter
{
private Context context;
private ArrayList<ParserCategory> lis;
public ImageAdapter(Context c, ArrayList<ParserCategory> mList)
{
context = c;
lis = mList;
}
public int getCount() {
return lis.size();
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
convertView = inflater.inflate(R.layout.raddioshowimage, null);
}
TextView textView = (TextView) convertView.findViewById(R.id.textView1);
String strPath = lis.get(position).toString();
// Get File Name
String fileName=lis.get(position).getCname();
textView.setText(lis.get(position).getCname());
ImageView imageView = (ImageView) convertView.findViewById(R.id.imageView1);
RadioButton radiobtn = (RadioButton) convertView.findViewById(R.id.radio);
radiobtn.setTag(fileName);
return convertView;
}
}
}
When I run the above code it selects multiple items with radiobutton, but I want a single item selection when I click a button so any idea how can I solve it?
