If a control such as a button or a checkbox is included in the ListItem, by default ListItem loses focus, resulting in an event that cannot respond to item, the most common solution
is in the Descendantfocusability property is set in the ListItem layout file.
The layout file for item:
<?xml version= "1.0" encoding= "Utf-8"? ><relativelayout xmlns:android= "http://schemas.android.com/apk/res/ Android "Android:layout_width=" Wrap_content "android:layout_height=" wrap_content "android:paddingtop=" 10DP " Android:paddingbottom= "10DP" android:paddingleft= "5DP" android:paddingright= "5DP" android:descendantfocusability= "Blocksdescendants" ><!--Add this property--<checkbox android:id= "@+id/history_item_checkbt" Android:layout_ height= "30DP" android:layout_width= "Wrap_content" android:layout_centervertical= "true" Android:layout_ Alignparentleft= "true" android:checked= "false" > </CheckBox> <imageview android:id= "@+id/history_item_ Image "Android:layout_width=" wrap_content "android:layout_height=" Wrap_content "android:layout_centervertical=" True "android:layout_torightof=" @id/history_item_checkbt "android:background=" @drawable/item_icon "> </ imageview> <button android:id= "@+id/history_item_edit_bt" Android:layoUt_alignparentright= "true" android:layout_width= "Wrap_content" android:layout_height= "Wrap_content" Android: Layout_centervertical= "true" android:text= "edit" android:textcolor= "#ffffff" android:textsize= "14SP" Android:backgro und= "@drawable/button_bg" > </Button> <textview android:id= "@+id/history_item_time_tv" Android:layout_ Width= "Wrap_content" android:layout_height= "Wrap_content" android:layout_centervertical= "true" android:textColor= "#565C5D" android:textsize= "14sp" android:text= "10-01 10:20" android:layout_marginright= "5DP" Android:layout_tolef tof= "@id/history_item_edit_bt" > </TextView> <textview android:id= "@+id/history_item_title_tv" Android: layout_height= "Wrap_content" android:layout_width= "Fill_parent" android:layout_centervertical= "true" Android: Textcolor= "#565C5D" android:textsize= "14sp" android:text= "xxxxxxxxxxxxxxxxxxxxxxxx" android:ellipsize= "End" Androi d:maxlines= "1" android:layout_torightof= "@id/History_item_image "android:layout_toleftof=" @id/history_item_time_tv "android:layout_marginleft=" 3DP "> </ Textview></relativelayout>
android:descendantfocusability
Defines the relationship between the ViewGroup and its descendants when looking-a View to take focus.
Must be one of the following constant values.
This property is defined as the relationship between ViewGroup and its child controls when one gets the focus for the view.
There are three types of values for the property:
Beforedescendants:viewgroup takes precedence over its subclass control and gets to focus
Afterdescendants:viewgroup gets focus only if its subclass control does not need to get focus
Blocksdescendants:viewgroup overrides the subclass control and gets the focus directly
We are using the third one.
