Listview con CheckedTextView.

Question

Ho due domande:

.

1. Se sto usando CheckedTextView in un ListView e la mia classe si estende solo Activity (anziché ListActivity), dal momento che ho un altro pulsante in basso sotto il mio ListView, Quale evento dovrei ascoltare, quando una casella di controllo è selezionata nel CheckedTextView?

2. Se estendo la mia classe per utilizzare ListActivity, posso utilizzare l'evento onListItemClick, giusto?Come posso aggiungere un nuovo pulsante a questo tipo di layout?

   Ecco il mio codice ..

   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);
   
       m_versionText=(TextView)findViewById(R.id.versionText);
       m_versionText.setText("Android Version is:" + Build.VERSION.RELEASE);
       m_btnAllCalendars = (Button)findViewById(R.id.btn_allCalendars);
       m_btnAllCalendars.setOnClickListener(mCalendarListener);
       m_calendarList=(ListView)findViewById(R.id.calList);
   
       //populateList uses simplecursoradapter to add items to the listview..(this part is working)
   
       populateList();
       m_calCheckText = (CheckedTextView)findViewById(R.id.calTextView);
       m_calCheckText.setOnClickListener(new OnClickListener(){
           @Override
           public void onClick(View v){
           if (((CheckedTextView)v).isChecked())
           {
               Log.d(TAG,"i am inside ...its checked");
           }
       }
   
       });
   
        private void populateList(){
   
           Log.d(TAG,"inside populateList");
           Cursor cursor = getAllCalendars();
           startManagingCursor(cursor);
   
           SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,R.layout.cal_list,cursor,new String[]{"displayName"},new int []{R.id.calTextView});
           //m_calendarList.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
           m_calendarList.setAdapter(adapter);
         }
   
    }

   Aggiornamento :::

           SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,R.layout.cal_list,cursor,new String[]{"displayName"},new int []{R.id.calTextView});
           m_calendarList=getListView();
           m_calendarList.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
           m_calendarList.setAdapter(adapter);
           m_calendarList.setOnItemClickListener(new OnItemClickListener(){
               public void onItemClick(AdapterView<?> parent, View view,int position,long id)
               {
                   Log.d(TAG,"I am inside onItemClick and position is:"+String.valueOf(position));
               CheckedTextView ctv = (CheckedTextView)view;
       the below code didnt work too           
             //CheckedTextView ctv = (CheckedTextView)view.findViewById(R.layout.cal_list);
                   ctv.setChecked(!ctv.isChecked());
   
               }
   
           });

Answer 1

You could try this:

m_calendarList.setAdapter(adapter);
m_calendarList.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        // do something here...
        // m_calendarList.getCheckedItemPosition(); will also give you the position
    }
});

EDIT:

m_calendarList.setOnItemClickListener(new OnItemClickListener(){
    public void onItemClick(AdapterView<?> parent, View view,int position,long id) {
        View v = m_calendarList.getChildAt(position);
        CheckedTextView ctv = (CheckedTextView) v.findViewById(R.id.cal_id);
    }
});

Answer 2

You can use CheckedTextView.setOnClickListener() Inside the onClick() method of your listener you can use CheckedTextView.isChecked() to find out whether it was it was checked or unchecked.

Edit: Here is an example of the getView() method for your Adapter.

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        v = convertView;
        if (v == null) {
            LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            v = vi.inflate(R.layout.row, null);
        }
        m_calCheckText = (CheckedTextView)v.findViewById(R.id.calTextView);
        m_calCheckText.setOnClickListener(new OnClickListener(){

            @Override
            public void onClick(View v){
                if (((CheckedTextView)v).isChecked())
                {
                   Log.d(TAG,"i am inside ...its checked");
                }
            }
        });

        return v;
    }
