如何在Listview上设置onItemselectlistener？

Answer 1

这是示例代码List OnItemClickListener。

我的代码是：

 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);

    }
});

希望这会有所帮助!!
