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！
public class CustomSpinner extends Activity {
String[] numbers = { "One", "Two", "Three", "Four", "Five" };
@Override
public 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;
}
}
