关于Spinner控件几点说明

1. 关于获取Spinner 控件的Item

代码示例如下

Spinner spinner = (Spinner)findViewById(R.id.spinnerYwy);spinner.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,arrayListJsr));spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {   @Override   public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {       Toast.makeText(CkPxmAddActivity.this,""+adapterView.getItemAtPosition(i),Toast.LENGTH_LONG).show();   }   @Override   public void onNothingSelected(AdapterView<?> adapterView) {   }});

 主要是调用 adpterView对象的getItemAtPostion()方法，该方法有一个int参数，用于指定要获取的Item索引 即 int i 参数
