如何在 android Listview 中使用 LinearLayout 而不是 CheckedTextView

Question

i want to implement listview with LinearLayout item (it will contain CheckedTextView and multiple textview).
so i want use LinearLayout instead of CheckedTextView in ListView. i tried but the radio button state is not changing.
my code:

    getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);
    getListView().setItemsCanFocus(false);
    setListAdapter(new ArrayAdapter(this,R.layout.list_item,android.R.id.text1,COUNTRIES));

list_item

 <CheckedTextView
        .....
        />

i want like this
list_item_new

<LinearLayout>
        .....
        <CheckedTextView/>
        <TextView/>
.....
</LinearLayout>

If you want to customise the way list items are appearing, you'll need to implement your own adapter. It's much simpler than you think. Here's the basic code for you:

public class MyAdapter extends BaseAdapter {
    List myData;
    Context context;

    public MyAdapter(Context ctx, List data) {
        context = ctx;
         myData = data;
    }

    public int getCount() { return myData.size(); }

    public Object getItem(int pos) { return myData.itemAt(pos); }

    public int getItemId(int pos) { return pos; }

    public View getView(int position, View convertView, ViewGroup parent) {
        //this is where you create your own view with whatever layout you want
        LinearLayout item;
        if(convertView == null) {
            //create/inflate your linear layout here
            item = ...;
        }
        else {
            item = (LinearLayout) convertView;
        }

        //now create/set your individual components inside your layout based on your element
        //at the requested position
        ...
    }
}

and that's all it is to it.
