最近项目中用ListView ,ListView的item是EditText,然后设置EditText的值，一拉ListVIew,EditText中的值就改变了，然后自己就上网找了资料，现在将方法总结一下，菜鸟第一次写博客，大牛勿喷
main.xml 里面只有一个ListView
<?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="fill_parent" android:orientation="vertical" > <ListView android:id="@+id/listView" android:cacheColorHint="#000000" android:layout_width="fill_parent" android:layout_height="wrap_content" > </ListView></LinearLayout>
listView 每一个item布局，里面只有一个EditText
<?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="fill_parent" android:orientation="vertical" > <EditText android:id="@+id/editText1" android:layout_width="fill_parent" android:layout_height="wrap_content"> </EditText></LinearLayout>java 代码：注释写的很清楚

如果你想得到每个editText中的值，根据position就可以拿到啦
