Question

我使用TextView和CheckBox自定义ListView布局。一切正常。我想要的是，当我点击CheckBox或TextView（在ListView的单个View上）时，两者都应该像一个对象。（我可以单击CheckBox，它不会影响TextView，TextView对CheckBox没有影响。）代码没有问题。

我已经实施了所有可能的解决方案，但问题仍然存在。（单击列表中的每个对象都应该考虑完整行的一个完整点击。）我希望我解释得很好。

主要活动

package com.example.smsplanner;

public class SMSPlanner extends ListActivity      {

    ListView contactsListView;

    private String TAG = "SMSPlanner";    CheckBox check;
    int count;

    List<ContactInfo> list = new ArrayList<ContactInfo>();
    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        ph = new String[3];
        phType = new String[3];
        LoadContactListFromPhone();
        ContactsAdapter contactadAdapter = new ContactsAdapter(this, list);
        getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);
        setListAdapter(contactadAdapter);
    }    
    @Override
    public void onListItemClick(ListView parent, View v, int position, long id)
    {
        TextView tx =(TextView)v.findViewById(R.id.firstname);
        TextView ph =(TextView)v.findViewById(R.id.phone);
        Toast.makeText(this, tx.getText().toString() + " " + ph.getText().toString() + " " + Integer.toString(count), Toast.LENGTH_SHORT).show();

    }
    final class ContactHolder{
        TextView txtviewfirstname;
        CheckBox chkselected;
        TextView txtviewphone;
    }
    void LoadContactListFromPhone()
    {
        loadlistandreturns();
    }

    void call()
    {
        Toast toast = Toast.makeText(this, "Called...",Toast.LENGTH_LONG);
        toast.show();
    }
}

CUSTOM ADAPTER

public class ContactsAdapter extends ArrayAdapter<ContactInfo> 
{

    private final Activity context;
    int resourceid;

    List<ContactInfo> list = null;
    public ContactsAdapter(Activity context, List<ContactInfo> list) {
        super(context, R.layout.contactrow, list);
        this.context = context;
        this.list = list;
    }

    @Override
    public View getView(int position, View convertview, ViewGroup viewgroup){
        View view = null;
        if(convertview == null){
            LayoutInflater inflater = context.getLayoutInflater();
            view = inflater.inflate(R.layout.contactrow, null);

            ContactHolder holder = new ContactHolder();

            holder.txtviewfirstname = (TextView)view.findViewById(R.id.firstname);
            holder.txtviewphone = (TextView)view.findViewById(R.id.phone);
            holder.chkselected = (CheckBox)view.findViewById(R.id.check);
            view.setTag(holder);
        }
        else{
            view = convertview;
        }
        ContactHolder holder2 = (ContactHolder) view.getTag();
        holder2.txtviewfirstname.setText(list.get(position).firstname);
        holder2.txtviewphone.setText(list.get(position).phonenumber);
        holder2.chkselected.setChecked(list.get(position).selected);
        return view;
    }


    final class ContactHolder{
        TextView txtviewfirstname;
        CheckBox chkselected;
        TextView txtviewphone;
    }
}

Answer 1

1。默认情况下，ListView的所有行都可以收听点击....

您必须实施 onItemClickListener()才能获得ListView ....

请参阅此示例：

Answer 2

您可以使用CheckedTextView，或者您可以创建一个可检查布局，如下所示：

Answer 3

   i think you should make adapter as

 public class ContactsAdapter extends BaseAdapter {

    ArrayList<ContactInfo> mlist;
    Context mcontext;


public BluetoothChatadpter(Context context,ArrayList<ChatInfo> mchtlist) {      
        mlist =  mchtlist;
        mcontext = context;

    }

    @Override
    public int getCount() {
        return mlist.size();
    }

    @Override
    public Object getItem(int postion) {
        return mlist.get(postion);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
        public View getView(int position, View convertview, ViewGroup viewgroup){
            View view = null;
            if(convertview == null){
                LayoutInflater inflater = context.getLayoutInflater();
                view = inflater.inflate(R.layout.contactrow, null);

                ContactHolder holder = new ContactHolder();

                holder.txtviewfirstname = (TextView)view.findViewById(R.id.firstname);
                holder.txtviewphone = (TextView)view.findViewById(R.id.phone);
                holder.chkselected = (CheckBox)view.findViewById(R.id.check);

                setOnClickListener(new OnClickListener() {
        @Override
            public void onClick(View arg0) {
            // to open the selected file in resp

                  // do your work here
                 }});


    chkselected .setOnClickListener(new OnClickListener() {
        @Override
    public void onClick(View v) {
    // Toast.makeText(context,// "checked is clicke="+pos, 12).show();
            if (chkselected.isChecked())          
                       {            

                        // do your work here
            } else {

     // do your work here                               
            }
        }
});



            view.setTag(holder);

        }
            else{
                view = convertview;
            }
            ContactHolder holder2 = (ContactHolder) view.getTag();
            holder2.txtviewfirstname.setText(list.get(position).firstname);
            holder2.txtviewphone.setText(list.get(position).phonenumber);
            holder2.chkselected.setChecked(list.get(position).selected);
            return view;
        }

}
