推荐答案

在您的xml文件中，您正在使用textview作为列表项.而不是使用 CheckedTextView .您可以将其直接从窗口小部件面板中拖放.您可以将 CheckedTextView 用作 TextView 和 CheckBox .下面是一个如何使用它的示例

In your xml file you're using textview as list item. Instead of that use CheckedTextView. You can directly drag and drop that from your widgets palette. You can use the CheckedTextView as both TextView and CheckBox. Below is an example if how to use it

   <CheckedTextView 
      xmlns:android="http://schemas.android.com/apk/res/android"     
      style="@style/NormalText"  
      android:id="@+id/checkList" 
      android:paddingLeft="20dip" 
      android:paddingRight="20dip" 
      android:paddingTop="10dip"
      android:paddingBottom="10dip" 
      android:orientation="vertical" 
      android:layout_width="fill_parent" 
      android:layout_height="?android:attr/listPreferredItemHeight"  
      android:gravity="center_vertical"  
      android:checkMark="@drawable/our_checkbox"></CheckedTextView>
