任何人都可以建議如何清除按鈕上的微調值?按鈕上的清除微調按下

Spinner spinner1; 
private static final String[] SpinArray= { "00", "01", "02", 
     "03", "04", "05", "06", "07", "08", "09", "10", "11", "12", "13", 
     "14", "15", "16", "17", "18", "19", "20", "21", "22", "23", "00" }; 


adapter = new ArrayAdapter(this, android.R.layout.simple_spinner_item, 
      SpinArray); 
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
    spinner1.setAdapter(adapter); 

    spinner1.setOnItemSelectedListener(new mySpinnerListener()); 

public void onItemSelected(AdapterView parent, View v, int position, 
      long id) { 
     // TODO Auto-generated method stub 
     switch(parent.getId()){ 
     case R.id.spinner1: 
      spinner1=parent.getSelectedItem().toString(); 
      break; 

    } 

上按一下按鈕我試圖使用

spinner1.setAdapter(null); and spinner1.setOnItemSelectedListener(null); 

這兩個並沒有我的情況下工作,以清除..請幫助

spinner1.getAdapter().clear();應該做的伎倆。

正如埃裏克在評論中所說,之後請致電spinner1.getAdapter().notifyDataSetChanged();

此後,您也可能需要調用'.notifyDataSetChanged()'。 – Eric 2012-07-28 17:32:29

對於Spinner,不贊成使用notifydatasetchanged。 – 2014-01-02 22:34:31

沒有任何方法.clear() – SAndroidD 2014-08-08 10:41:24

點擊按鈕,我清除了arraylist,並使微調適配器爲空。

arrContent.clear(); 
spinner1.setAdapter(null);
