CheckBox and setOnItemClickListener not working in android

问题

I am using ListView with CheckBox. I have selected only one CheckBox but it's automatically selected into Multiple Rows using ScrollView.

Sample Code (This Code is working Perfectly)

       holder.checkbox.setOnClickListener( new OnClickListener()
        {
            public void onClick( View v )
            {
                CheckBox cb = ( CheckBox ) v;
                if ( cb.isChecked() )
                {
                    test[position] = true;
                    holder.checkbox.setChecked(test[position]);
                }
                else
                {
                    test[position] = false;
                    holder.checkbox.setChecked(test[position]);
                }
            }
        });
        holder.checkbox.setChecked(test[position]);

But When i uses setOnItemClickListener it's not working.

Sample Code (This code is not working for me)

        listview.setOnItemClickListener( new OnItemClickListener() 
        {
            public void onItemClick( AdapterView<?> parent, final View v, final int position, long id ) 
            {
                holder.checkbox = ( CheckBox ) v.findViewById( R.id.lock_File_CheckBox );
                if ( holder.checkbox.isChecked() )
                {
                    test[position] = false;
                    holder.checkbox.setChecked(test[position]);
                }
                else
                {
                    test[position] = true;
                    holder.checkbox.setChecked(test[position]);
                }
            }
        });
        holder.checkbox.setChecked(test[position]);

Where i can mistaken. How do avoid this CheckBox Selection.

Can you please help me?

回答1:

You can get the instance of CheckBox inside onItemClick() by using setTag() and getTag(). You can setTag the CheckBox instance inside your getView() method as

convertView.setTag(R.id.check, viewHolder.checkbox);

And get the instance inside onItemClick() using,

CheckBox checkbox = (CheckBox) v.getTag(R.id.check);

If you have any further query you can check my blog post.

To make your listview focusable, remove focus from the items themselves. Add the following after instantiating listview:

listview.setItemsCanFocus(false);

Then add the following to your list_item.xml

<CheckBox
    android:id="@+id/lock_File_CheckBox"
    android:focusable="false"
    android:focusableInTouchMode="false"/>

With this, your setOnItemClickListener() will get called

Don't use onClick. Use OnCheckedChange

holder.checkbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked) {
            if (isChecked) {
                doSomethingWithCheckedState(compoundButton);
            } else {
                doSomethingWithUnCheckedState(compoundButton);
            }
        }
    });

Keep in mind that CheckBox inherit from CompoundButton for ICS's switch compatibility.

Focusable view in the list item prevents the firing of onListItemClick() in the ListActivity when the list item is clicked. But the effect of onListItemClick() can be achieved with OnClickListener. Read here more about this
