如何在每个微调框中显示微调项目以及每个微调项目的计数

我有2个微调控制器。第1个微调控制器显示城市和第2个微调控制器显示基于微调控制器1上所选城市的区域。例如，如果城市孟买有5个区域。 ..我的第一个微调应该显示孟买（5），同样也适用于其他城市。这里是我的代码：如何在每个微调框中显示微调项目以及每个微调项目的计数

我对spinner1

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" android:layout_height="match_parent"

XML代码最后告诉我如何在每个喷丝的项目的计数一起显示旋转器

输出： spinner1应该在下拉作为

孟买（5）加尔各答（4）奈（4）

显示然后微调器2显示每个微调器项目中存在的项目

您可以使用包含文本和计数的布局编写自定义数组适配器，并从t他在自定义适配器中获取了DropDownView方法。

如果项目的位置！= 0，则隐藏计数文本以防止计数显示在行项目中。 –

感谢您的回复...可以用示例代码来解释@Sudheesh Mohan –
