列表视图与checkedtextview [英] Listview with checkedtextview

问题描述

我有两个问题：

1. 如果我使用 CheckedTextView 在的ListView 和我的类只扩展活动（而不是 ListActivity ），因为我在下面的底部还有一个按钮，我的的ListView ，
   我应该听什么样的事件上，当 CheckedTextView

选中复选框


2. 如果我致以类使用 ListActivity ，我可以使用 onListItemClick 事件，对吧？我如何添加一个新的按钮，这种布局的？

下面是我的code ..

 公共无效的onCreate（捆绑savedInstanceState）{
    super.onCreate（savedInstanceState）;
    的setContentView（R.layout.main）;    m_versionText =（的TextView）findViewById（R.id.versionText）;
    m_versionText.setText（Android版本：+ Build.VERSION.RELEASE）;
    m_btnAllCalendars =（按钮）findViewById（R.id.btn_allCalendars）;
    m_btnAllCalendars.setOnClickListener（mCalendarListener）;
    m_calendarList =（ListView控件）findViewById（R.id.calList）;    // populateList使用simplecursoradapter将项目添加到列表视图。（这部分工作）    populateList（）;
    m_calCheckText =（CheckedTextView）findViewById（R.id.calTextView）;
    m_calCheckText.setOnClickListener（新OnClickListener（）{
        @覆盖
        公共无效的onClick（视图v）{
        如果（（（CheckedTextView）ⅴ）.isChecked（））
        {
            Log.d（TAG，我是里面...它检查）;
        }
    }    }）;     私人无效populateList（）{        Log.d（TAG，里面populateList）;
        光标光标= getAllCalendars（）;
        startManagingCursor（光标）;        SimpleCursorAdapter适配器=新SimpleCursorAdapter（这一点，R.layout.cal_list，光标，新的String [] {显示名}，新的INT [] {R.id.calTextView}）;
        //m_calendarList.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE）;
        m_calendarList.setAdapter（适配器）;
      } }
 

更新:::

  SimpleCursorAdapter适配器=新SimpleCursorAdapter（这一点，R.layout.cal_list，光标，新的String [] {显示名}，新的INT [] {} R.id.calTextView） ;
        m_calendarList = getListView（）;
        m_calendarList.setChoiceMode（ListView.CHOICE_MODE_MULTIPLE）;
        m_calendarList.setAdapter（适配器）;
        m_calendarList.setOnItemClickListener（新OnItemClickListener（）{
            公共无效onItemClick（适配器视图＆LT;＆GT;母公司，观景，INT位置，长的ID）
            {
                Log.d（TAG，我是里面onItemClick和立场是：+将String.valueOf（位置））;
            CheckedTextView CTV =（CheckedTextView）视图。
    下面code没有工作过
          // CheckedTextView CTV =（CheckedTextView）view.findViewById（R.layout.cal_list）;
                ctv.setChecked（ctv.isChecked（）！）;            }        }）;
 

解决方案

您可以试试这个：

  m_calendarList.setAdapter（适配器）;
m_calendarList.setOnItemClickListener（新OnItemClickListener（）{
    公共无效onItemClick（适配器视图＆LT;＆GT;母公司，观景，INT位置，长的id）{
        //做一些事情在这里...
        // m_calendarList.getCheckedItemPosition（）;也会给你的位置
    }
}）;
 

编辑：

  m_calendarList.setOnItemClickListener（新OnItemClickListener（）{
    公共无效onItemClick（适配器视图＆LT;＆GT;母公司，观景，INT位置，长的id）{
        视图V = m_calendarList.getChildAt（位置）;
        CheckedTextView CTV =（CheckedTextView）v.findViewById（R.id.cal_id）;
    }
}）;
 

I have two questions:

1. If I am using CheckedTextView in a ListView and my class only extends Activity (instead of ListActivity), since I have another button at the bottom below my ListView, what event should I listen on, when a checkbox is selected in the CheckedTextView?

2. If I extend my class to use ListActivity, I can use onListItemClick event, right? How can I add a new button to this type of layout?

Here is my code..

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);
      }

 }

UPDATE:::

        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());

            }

        });

解决方案

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);
    }
});
