Question

下面是我想要扩展视图的ArrayAdapter，以满足我对下拉微调器的需求。

    ArrayAdapter<String> arrShirtType = new ArrayAdapter<String>
        (this, android.R.layout.simple_spinner_item,shirtType)
        {
            private LayoutInflater inflater = LayoutInflater.from(getBaseContext());
            public View getView(int position, View convertView,ViewGroup parent) 
                {
                    View vi = convertView;
                    vi = inflater.inflate(R.layout.spinner_view_style, parent);
                    TextView txt = (TextView)findViewById(R.id.spinner_textview);
                    ((TextView) vi).setTypeface(font1);
                    ((TextView) vi).setTextSize(65);
                    return vi;
                }
            public View getDropDownView(int position, View convertView,ViewGroup parent) 
                {   
                    View vi = convertView;
                    vi = inflater.inflate(R.layout.spinner_view_style, parent);
                    TextView txt = (TextView)findViewById(R.id.spinner_textview);
                    ((TextView) vi).setTypeface(font1);
                    ((TextView) vi).setTextSize(65);
                    return vi;
                }
        };

Answer 1

您必须初始化您的inflater。例如：

inflater = LayoutInflater.from(context);

为spinner </string>设置自定义视图到ArrayAdapter <string>时出错
