Android 根据列表视图中的条件对行进行排序

我已经使用setAdapter填充了列表视图，如下所示

cursor = manifest_helper.GetDeliveriesAgainstManifest(pkManifest);





    cursor.moveToFirst();

    for (int i = 0; i < cursor.getCount(); i++) {

        map = new HashMap<String, String>();
        map.put("Deliv_Address",
                cursor.getString(cursor.getColumnIndex("Address")));
        map.put("Deliv_Time",
                cursor.getString(cursor.getColumnIndex("Time")));
        map.put("Deliv_Order",
                cursor.getString(cursor.getColumnIndex("DeliveryOrder")));
        map.put("Deliv_IsCustomerPickup",
                cursor.getString(cursor.getColumnIndex("IsCustomerPickup")));
        map.put("Deliv_FKDeliveryStatus",
                cursor.getString(cursor.getColumnIndex("FKDeliveryStatus")));
        map.put("Deliv_PKDelivery",
                cursor.getString(cursor.getColumnIndex("PKDelivery")));
        alist.add(map);
        cursor.moveToNext();


    }
    sd = new SimpleAdapter(this, alist, R.layout.deliveries_list_row,
            new String[] { "Deliv_Address", "Deliv_Time",
                    "Deliv_Order", "Deliv_IsCustomerPickup",
                    "Deliv_FKDeliveryStatus", "Deliv_PKDelivery" },
            new int[] { R.id.tv_Deliv_Address, R.id.tv_Deliv_Time,
                    R.id.tv_Deliv_Order,
                    R.id.tv_Deliv_IsCustomerPickup,
                    R.id.tv_Deliv_FKDeliveryStatus,
                    R.id.tv_Deliv_PKDelivery });
    //selectedAdapter = new SelectedAdapter(this, 0, alist);
    //selectedAdapter.setNotifyOnChange(true);

    ListDeliveries.setAdapter(sd);

cursor=manifest\u helper.getDeliveriesAgainsManifest（pkManifest）；
cursor.moveToFirst（）；
对于（int i=0；i

问题是我有一个字段“IsCustomerPick”，它的值为C或O。

我想用不同的颜色来区分每一行…有人能帮我吗…请

您需要将SimpleAdapter扩展到您自己的CustomAdapter类中，该类能够读取ISCustomerPick值并相应地设置rowView背景。

您可以使用listview的自定义适配器来实现这一点。关于如何在网络上实现这一点，有无数的教程。e、 g:

我认为这不适用于Simpel适配器。 我认为您必须在自定义适配器上编写，并创建自己的listitem布局。 作为列表项的根，采用线性布局。 使您自己的适配器覆盖getView（）方法

以下是一些片段： 在布局文件中创建listview。 然后做一个 自定义_listview_row.xml，包括：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/ll_root_listview_row"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <TextView
        android:id="@+id/tv_listview_row"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="your row text" />
</LinearLayout>

我还没有测试过这个适配器，但我认为您可以使用它，并根据需要调整它

希望这有帮助
