android - 两个textviews listview android

Question

我在导航抽屉中的列表视图中实现了搜索功能。但目前它只有一个文本视图。我希望能够在同一行添加两个文本视图，而不需要不同的类或适配器。话虽如此，我仍然希望能够搜索第一个 textview。所以基本上我的问题是：如何在不使用任何其他类的情况下将两个文本视图添加到列表视图中的一行？

这是我的代码：listitem_row.xml

<!-- This is the xml which i use to display one textview on a list row-->

<?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="50dp"
android:orientation="horizontal"
android:padding="10dp"
android:gravity="center_vertical">

<TextView
    android:id="@+id/textView1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="TextView"
    android:textAppearance="?android:attr/textAppearanceLarge" >
</TextView>

</LinearLayout>

main_activity.xml

<!--This is my main activity xml where I have the navigation drawer and the  
listview inside the drawer-->

要绑定两个TextViews，您需要创建Custom Array Adapter. 转到以下链接以更好地理解：
