listview採用ArrayAdapter時, 如何修改字型,行數等layout

可以採用繼承ArrayAdapter的方式, 自定一個class, 然後改寫getView

如下:

    class MyArrayAdapter extends ArrayAdapter
    {
        public MyArrayAdapter(Context context, int resource, int textViewResourceId, Object[] objects) {
            super(context, resource, textViewResourceId, objects);
        }

        @Override        public View getView(int position, View convertView, ViewGroup parent)
        {
            View view = super.getView(position, convertView, parent);

            TextView textView = (TextView)view.findViewById(android.R.id.text1);

            //You can increase number of lines in the text view            //textView.setSingleLine(true);            textView.setMaxLines(2);
            //textView.setEllipsize(TextUtils.TruncateAt.START);
            ViewGroup.LayoutParams params = textView.getLayoutParams();
            if(params.height > 0)
            {
                int height = params.height;
                params.height = ViewGroup.LayoutParams.WRAP_CONTENT;
                textView.setLayoutParams(params);
                //textView.setMinHeight(height);            }

            //Or you can make your font smaller            textView.setTextSize(14);

            //or whatever you like, even apply new custom style            //...
            return view;
        }
    }

使用時, 將ArrayAdapter改成MyArrayAdapter

lstview.setAdapter(new MyArrayAdapter(getActivity(),
        android.R.layout.simple_list_item_multiple_choice,
        android.R.id.text1, folderItem));
