1. Create a new Android Project<\/h3>\n
Open Eclipse IDE and go to File -> New -> Project -> Android -> Android Application Project and click Next.<\/p>\n
You have to specify the Application Name, the Project Name and the Package name in the appropriate text fields and then click Next.<\/p>\n In the next window make sure the \u201cCreate activity\u201d option is selected in order to create a new activity for your project, and click Next. This is optional as you can create a new activity after creating the project, but you can do it all in one step.<\/p>\n Select \u201cBlankActivity\u201d and click Next.<\/p>\n You will be asked to specify some information about the new activity. \u00a0In the Layout Name text field you have to specify the name of the file that will contain the layout description of your app. In our case the file\u00a0 Go to the Package Explorer and open\u00a0 And paste the following code:<\/p>\n Now, we have to create a new XML file that will describe the layout of the items in the list.<\/p>\n Go to the Package Explorer and right click on the\u00a0 Then specify the name of the file and the Layout type and click Finish:<\/p>\n As you will see in the Package Explorer the new\u00a0 Open that file and paste the following code:<\/p>\n This class will simply represent the items in the lists. Go to the Package explorer:<\/p>\n Right click on the package \u00a0-> New -> Class. Fill out the name of \u00a0the class, as show in the picture below:<\/p>\n Now open the source file of the class and paste the following code:<\/p>\n Student.java:<\/span><\/em><\/p>\n To inflate the ListView with Items, we need an As before, go to the package explorer, right click on the package \u00a0-> New -> Class. Fill out the name of \u00a0the class, and the Now open the source file of the class and paste the following code:<\/p>\n MyArrayAdapter.java:<\/em><\/span><\/p>\n Now open the source file of the Student.java:<\/em><\/span><\/p>\n This is the\u00a0main screen of our Application:<\/p>\n Now, when you click on an Item in the list:<\/p>\n And when you click “Edit” and “Delete”:<\/p>\n This was an Android MultiTouch ListView Example. Download the Eclipse Project of this tutorial:\u00a0AndroidMultiTouchList.zip<\/a> In this example we are going to see how to create MutliTouch ListView in an Android Application. In this example, every Item in the list is clickable, so you can bundle it with a ClickListener, \u00a0and it contains two buttons to edit and delete items. For this tutorial, we will use the following tools in …<\/p>\n","protected":false},"author":4,"featured_media":1202,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[309],"tags":[437,435,436],"class_list":["post-3562","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-listview","tag-adapterview","tag-arrayadapter","tag-layoutinflater"],"yoast_head":"\n![\"\"](\"http:\/\/cdn.javacodegeeks.com\/wp-content\/uploads\/2013\/01\/create-new-project6.jpg\" "\\"create-new-project\\"")

3. Create a new xml Layout file<\/h3>\n
res\/layout\u00a0<\/code>folder. Select New -> Other -> Android -> Android XML Layout File.

4. Create a Student class<\/h3>\n
<\/a><\/p>\n<\/a><\/p>\npackage com.javacodegeeks.android.example.androidmultitouchlist;\r\n\r\npublic class Student {\r\n\tprivate String name;\r\n\tprivate String age;\r\n\tprivate String address;\r\n\r\n\tpublic Student(String name, String age, String address) {\r\n\t\tsuper();\r\n\t\tthis.name = name;\r\n\t\tthis.age = age;\r\n\t\tthis.address = address;\r\n\t}\r\n\r\n\tpublic String getName() {\r\n\t\treturn name;\r\n\t}\r\n\r\n\tpublic void setName(String name) {\r\n\t\tthis.name = name;\r\n\t}\r\n\r\n\tpublic String getAge() {\r\n\t\treturn age;\r\n\t}\r\n\r\n\tpublic void setAge(String age) {\r\n\t\tthis.age = age;\r\n\t}\r\n\r\n\tpublic String getAddress() {\r\n\t\treturn address;\r\n\t}\r\n\r\n\tpublic void setAddress(String address) {\r\n\t\tthis.address = address;\r\n\t}\r\n}<\/pre>\n5. Create a custom ArrayAdapter<\/h3>\n
ArrayAdapter<\/code><\/a>.
