嗨下面是一些代碼ive一直在玩,但是當我調試它永遠不會得到onitemclicklisten例程任何人都可以幫助嗎?程序似乎永遠不會去onclick聽

//Create view of the list where content will be stored

String[] from = new String[] {"ProdName", "ProdSize", "ProdPack", "OrdQty"};
int[] to = new int[] { R.id.productlinerow, R.id.productlinerow2, R.id.productlinerow3, R.id.productlinerow4};
SimpleAdapter notes = new SimpleAdapter(OrderProductSearch.this,list,R.layout.productlinerow,from,to);
listContent.setAdapter(notes);
//Close the database
db.close();
listContent.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,

});
}
}
你如何驗證它沒有得到onItemClick? –
該列表是否顯示其所有項目?偵聽器例程僅在單擊項目時調用 - 實際上是否有項目? –
嗨屏幕顯示我的列表沒有問題,我甚至可以在edittext中輸入qty。邁克我在例程中放置了一些簡單的代碼,並在那裏放置了一個斷點 – shawrie
