如何在listview中获取选中复选框的文本并转移到android中的其他活动？

我想在listview中获取选中复选框的文本，并在单击按钮时将其传输到第二个活动。我需要一些代码来完成此操作…这就是我目前所做的。。 检查图片。。。及

这是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">
<Button
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:id="@+id/btest"
    android:layout_alignParentBottom="true"
    android:text="submit"
    />
<ListView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/list"
    android:layout_alignParentTop="true"
    android:layout_above="@+id/btest"
    android:clickable="true"
    >
    </ListView>

使用当前代码时遇到什么问题？描述您的问题我在listview中有复选框，但当我选中一些复选框并按下按钮将它们传输到listview2时，listview2中没有显示任何内容，即ResultActivity.java我想获取复选框的文本并将其传输到ResultActivity.java，然后在另一个listview2中显示它们尝试解决方案在这里
