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;}@Overridepublic 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;}@Overridepublic 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;}}
