如何在ListView上設置onItemselectlistener？

Answer 1

這是示例代碼列表OnItemClickListener。

我的代碼是：

String strarray[]=new String[100]; 
ArrayAdapter<String> adapterarray=new ArrayAdapter<String>(Classname.this,android.R.layout.simple_expandable_list_item_1,strarray); 
lv.setAdapter(adapterarray); 
lv.setTextFilterEnabled(true); 

lv.setOnItemClickListener(new OnItemClickListener() { 

    @Override 
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) 
    { 
     // TODO Auto-generated method stub 
     String str=lv.getItemAtPosition(arg2).toString(); 
     Toast.makeText(getApplicationContext(), "List is:"+str, Toast.LENGTH_LONG).show(); 

    Log.i(TAG,str); 

    } 
}); 

希望這將幫助！
