如何將EditText添加到ListView中

Question

我正在閱讀一些數據庫中的產品詳細信息，然後將它們添加到ListView中。

然後，我想在每行上的一個數量EditText框，客戶可以在其中添加數量。 我該怎麼做？我做了一個簡單的頁面，但是當我輸入一個數字並向下滾動然後再次備份時，我丟失了數據，或者它甚至出現在另一行的另一個數字框中。

好了，所以你需要做的第一件事是創建要在列表中的每一行有佈局的Row.xml文件..

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:orientation="horizontal" 
> 
<ImageView 
android:id="@+id/icon" 
android:padding="2dip" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:src="@drawable/ok" 
/> 
<TextView 
android:id="@+id/label" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:textSize="40sp" 
/> 
//Add a edittext here.. 
/LinearLayout> 

接下來，您將需要擴展列表視圖並重寫獲取視圖以加載您的自定義行。

public class Demo extends ListActivity { 

@Override 
public void onCreate(Bundle icicle) { 
super.onCreate(icicle); 
setContentView(R.layout.main); 
setListAdapter(new Adapter());} 

//Here extends a ArrayAdapter to create your custom view 
class Adapter extends ArrayAdapter<String> { 
Adapter() { 
super(DynamicDemo.this, R.layout.row, R.id.label, items); 
} 
public View getView(int position, View convertView, 
ViewGroup parent) { 
//Here load in your views such as the edittext 

} 

。這是你將需要開始，那麼你可以調用onItemListClick（）來獲取當用戶單擊該項目的每個點擊的東西。

此外，如果你想保存在數量框中的數字，你需要有一個包。 如 saveState（）方法

這將保存您的用戶數量，而應用程序仍然活着時，當帶回到視圖從數據包拉數字或int。

這應該是幫助下

您應該將狀態（用戶在EditText中輸入的內容）保存在提供給列表適配器的某種數組中。可能您在列表適配器的getView（）方法中創建新的EditText。
