We all know that the ListView is used to display a list of data, each list has a list of items, if we click to select a list, want to get the details of the list or open a new window to pass the list information in the past what to do? In this section we demonstrate the ListView click event, which we will have a deeper understanding of the ListView, first look at

Here's a look at the demo code

Main layout file

<?xml version= "1.0" encoding= "Utf-8"? ><linearlayout xmlns:android= "http://schemas.android.com/apk/res/ Android "    android:layout_width=" match_parent "    android:layout_height=" match_parent "    android:o rientation= "vertical" >        <listview        android:id= "@+id/listview1" android:layout_width= "Match_        Parent "        android:layout_height=" wrap_content ">    </ListView>    </LinearLayout>

List item Layout file

<?xml version= "1.0" encoding= "Utf-8"? ><linearlayout xmlns:android= "http://schemas.android.com/apk/res/ Android "Android:layout_width=" Match_parent "android:layout_height=" 100DP "android:orientation=" vertical "and roid:gravity= "Top" > <linearlayout android:layout_width= "match_parent" android:layout_height= "Wrap_    Content "android:orientation=" horizontal "> <linearlayout android:layout_width=" match_parent " android:layout_height= "wrap_content" android:orientation= "vertical" > <textview Android : id= "@+id/tvcode" android:layout_width= "wrap_content" android:layout_height= "Wrap_content" Android:la yout_margintop= "5DP" android:text= "code:"/> <textview android:id= "@+id/tvname" android:l Ayout_width= "Wrap_content" android:layout_height= "wrap_content" android:layout_margintop= "5DP" Androi d:text= "Name:"/> <texTView android:id= "@+id/tvprice" android:layout_width= "wrap_content" android:layout_height= "Wrap_conten T "android:layout_margintop=" 5DP "android:text=" Price: "/> <textview android:id = "@+id/tvmodel" android:layout_width= "wrap_content" android:layout_height= "Wrap_content" Android:layo ut_margintop= "5DP" android:text= "Size:"/> </LinearLayout> </LinearLayout> < LinearLayout android:layout_width= "fill_parent" android:layout_height= "2DP" android:background= "#F0F0F0" > </ Linearlayout></linearlayout>
