Question

我想用LinearLayout项目实现listview（它将包含CheckedTextView和多个textview）。
所以我想在ListView中使用LinearLayout而不是CheckedTextView。我试过但单选按钮状态没有改变我的代码：

    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
        .....
        />

我希望这样 list_item_new

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

如果要自定义列表项的显示方式，则需要实现自己的适配器。这比你想象的要简单得多。以下是您的基本代码：

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
        ...
    }
}

这就是它的全部内容。
