我正在使用odoo移动框架。我的Android应用程序将连接到odoo服务器。我从服务器获取产品并在listview中显示。我想从listview中获取多个选择值。这是我的代码。当我单击一个复选框时，另一个复选框也会自动检查。我不确定是由于OEListAdapter还是我错误的代码。
product_list.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="@+id/lvProductListView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipToPadding="false"
android:paddingTop="?android:attr/actionBarSize" >
</ListView>
</LinearLayout>
product_list_row.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:padding="5dp"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="@+id/imgvProductPic"
android:layout_width="42dp"
android:layout_height="42dp"
android:layout_gravity="center_vertical"
android:src="@drawable/ic_launcher" />
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="vertical"
android:padding="5dp" >
<TextView
android:id="@+id/txvProductName"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Product Name"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
android:id="@+id/txvQty"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Quantity"
android:textAppearance="?android:attr/textAppearanceSmall" />
<TextView
android:id="@+id/txvPrice"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ellipsize="end"
android:singleLine="true"
android:text="Price"
android:textAppearance="?android:attr/textAppearanceSmall" />
</LinearLayout>
<CheckBox
android:id="@+id/check"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_marginLeft="4dip"
android:layout_marginRight="10dip"
android:focusable="false"
android:focusableInTouchMode="false" >
</CheckBox>
</LinearLayout>
这是我的活动代码。

答案 0 :(得分：0)
我知道这个问题为时已晚，但是为了处理listview中的复选框，你应该使用viewholder模式， 创建一个boolean的arraylist，它将在这里存储你的选择是示例代码
arraylist宣言
public static ArrayList<Boolean> arrChecked;
初始化列表
for (int i = 0; i < data.size(); i++) {
arrChecked.add(false);
}
然后在getView方法中使用这样的持有者，
if (convertView == null) {
convertView = inflater.inflate(R.layout.listview_item, null);
ViewHolder viewHolder = new ViewHolder();
viewHolder.cb = (CheckBox) convertView.findViewById(R.id.checkbox);
// The tag can be any Object, this just happens to be the ViewHolder
convertView.setTag(viewHolder);
}
holder = (ViewHolder) convertView.getTag();
// set position as id
holder.cb.setId(position);
holder.cb.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
int id = v.getId();
if (arrChecked.get(id)) {
arrChecked.set(id, false);
// unchecked state of checkbox
} else {
arrChecked.set(id, true);
//do what you want to do in checked state here
}
}
});
holder.cb.setChecked(arrChecked.get(position));
