【android开发】 修改控件Spinner内容的字体大小 颜色等属性

      在anadroid开发中遇到此问题： 直接定义的Spinner控件，不能调整内容字体的大小，所以常会

因为控件太小，内容太长而使得不能完全显示，各种搜索，找到如下解决方法！希望对遇到同样问题

的朋友们提供帮助！

实现代码如下：

public class CustomSpinner extends Activity {String[] numbers = { "One", "Two", "Three", "Four", "Five" };@Overridepublic void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.main);    Spinner spinner = (Spinner) findViewById(R.id.spinner);    SpinnerAdapter adapter = new SpinnerAdapter(this,            android.R.layout.simple_spinner_item, numbers);    spinner.setAdapter(adapter);}private class SpinnerAdapter extends ArrayAdapter<String> {    Context context;    String[] items = new String[] {};    public SpinnerAdapter(final Context context,            final int textViewResourceId, final String[] objects) {        super(context, textViewResourceId, objects);        this.items = objects;        this.context = context;    }    @Override    public View getDropDownView(int position, View convertView,            ViewGroup parent) {        if (convertView == null) {            LayoutInflater inflater = LayoutInflater.from(context);            convertView = inflater.inflate(                    android.R.layout.simple_spinner_item, parent, false);        }        TextView tv = (TextView) convertView                .findViewById(android.R.id.text1);        tv.setText(items[position]);        tv.setTextColor(Color.BLUE);        tv.setTextSize(30);        return convertView;    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {        if (convertView == null) {            LayoutInflater inflater = LayoutInflater.from(context);            convertView = inflater.inflate(                    android.R.layout.simple_spinner_item, parent, false);        }        // android.R.id.text1 is default text view in resource of the android.        // android.R.layout.simple_spinner_item is default layout in resources of android.        TextView tv = (TextView) convertView                .findViewById(android.R.id.text1);        tv.setText(items[position]);        tv.setTextColor(Color.BLUE);        tv.setTextSize(30);        return convertView;    }}
