微調控制器單擊時如何調用方法？

Question

我有"one","two","three"具有列表微調，

我想調用一個方法，在旋轉每個選擇(that means when click spinner)。

是否有默認的方法可用時單擊spinner.So怎麼辦呢

Answer 1

這是什麼應該做的伎倆

 Spinner sp = new Spinner(this);   
     ArrayAdapter<String> aa = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, new 
     String[]{"one", "two", "three"});  
    sp.setAdapter(aa); 
     sp.setOnItemSelectedListener(new OnItemSelectedListener() { 
@Override 
public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) { 
    // your code here 
} 

@Override 
public void onNothingSelected(AdapterView<?> parentView) { 
    // your code here 
} 

}); 

Answer 2

你可以使用setOnItemSelectedListener您需要

spinner.setOnItemSelectedListener(new OnItemSelectedListener() { 
@Override 
public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) { 
    // your code here 
} 

@Override 
public void onNothingSelected(AdapterView<?> parentView) { 
    // your code here 
} 

});
