BaseAdapter实现ListView中item上每个控件的获取以及点击

借鉴这位大神的代码，自己稍微修改了一下（其实也没改多少

），把源码出来大家看看，刚开始学习android，有很多不懂的地方，望大家多多指教

先来一张效果图，点击任何一个button，获取button的值，具体动作，大家可以自行修改



activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">

<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/listView1">

</ListView>

</RelativeLayout>

layout_xml

<?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"
android:orientation="horizontal"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/text"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/button1"
/>

</LinearLayout>
