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>
