AndroidSpinner与适配器模式详解及实例代码

private String[] ss=new String[]{ 
    "猫咪", 
    "老虎", 
    "狮子", 
       
  }; 

private List list=new ArrayList(); 
list.add("百度"); 
    list.add("腾讯"); 
    list.add("阿里巴巴"); 

private class Myadapter extends BaseAdapter{ 
 
  @Override 
  public int getCount() { 
    // TODO Auto-generated method stub 
    return ss.length; 
  } 
 
  @Override 
  public Object getItem(int position) { 
    // TODO Auto-generated method stub 
    return null; 
  } 
 
  @Override 
  public long getItemId(int position) { 
    // TODO Auto-generated method stub 
    return 0; 
  } 
 
  @Override 
  public View getView(int position, View convertView, ViewGroup parent) { 
    // TODO Auto-generated method stub 
    TextView textView=new TextView(MainActivity.this); 
    textView.setText(ss[position]); 
     
    return textView; 
  } 

Spinner spinner=(Spinner) findViewById(R.id.spinner1); 
    BaseAdapter adapter=new Myadapter(); 
    spinner.setAdapter(adapter); 

Spinner spinner=(Spinner) findViewById(R.id.spinner1); 
    ArrayAdapter adapter=new ArrayAdapter(this,android.R.layout.simple_spinner_item,ss);
