Operating System

Android

In this tutorial we will try to create a Simple List View using Android. This simple app can be used to display multiple data as a list. Android also provide an adaptive framework that allow the developer to develop an apps in a simpler way. It used in several gadget like smartphone, tablet, and even television. Android is open source to developers who has an interest in developing mobile apps. So let's now do the coding...

Getting Started:

First you will have to download & install the Android Development IDE (Android Studio or Eclipse). Android Studio is an open source development feel free to develop your things.

Here's the link for the Android Studio https://developer.android.com/studio/index.html.

Layout Design

We will now create the design for the application, first to do is to create a resource that we will be using for the design. To create the resource, go to drawable folder then create a new xml file named border. Then write these certain block of codes inside the newly created file.

<?

xml version=

"1.0"

encoding=

"utf-8"

?>
<

shape xmlns:

android=

"http://schemas.android.com/apk/res/android"

android:

shape=

"rectangle"

>
<

solid android:

color=

"@android:color/white"

/>
<

stroke android:

width=

"2dp"

android:

color=

"#5BC0DE"

/>
</

shape>

Now that we're done with the graphic resource we will create then a layout that display the value of the list. First locate the layout file called name_list.xml, then write these codes inside your layout file.

<?

xml version=

"1.0"

encoding=

"utf-8"

?>
<

TextView xmlns:

android=

"http://schemas.android.com/apk/res/android"
android:

layout_width=

"match_parent"
android:

layout_height=

"match_parent"
android:

textSize=

"30sp"
android:

padding=

"15dp"

>
</

TextView>

Now that all the settings are ready we will now create the layout of the app. First locate the layout file called activity_main.xml, this is the default name when create a new activity. Then write these codes inside your layout file.

<?

xml version=

"1.0"

encoding=

"utf-8"

?>
<

RelativeLayout xmlns:

android=

"http://schemas.android.com/apk/res/android"
xmlns:

app=

"http://schemas.android.com/apk/res-auto"
xmlns:

tools=

"http://schemas.android.com/tools"
android:

layout_width=

"match_parent"
android:

layout_height=

"match_parent"
tools:

context=

"com.razormist.simplelistview.MainActivity"

>
<

TextView
android:

id=

"@+id/tv_title"
android:

layout_width=

"match_parent"
android:

layout_height=

"wrap_content"
android:

layout_alignParentTop=

"true"
android:

text=

"Programming Languages"
android:

textSize=

"30sp"
android:

gravity=

"center"
android:

layout_marginTop=

"20dp"
android:

layout_marginBottom=

"20dp"
android:

background=

"@drawable/border"

/>
<

ListView
android:

layout_below=

"@+id/tv_title"
android:

id=

"@+id/lv_display"
style=

"@Style/Widget.AppCompat.ListView"
android:

layout_width=

"match_parent"
android:

layout_height=

"match_parent"
android:

layout_alignParentLeft=

"true"
android:

layout_alignParentStart=

"true"
android:

footerDividersEnabled=

"false"
android:

headerDividersEnabled=

"true"

/>
</

RelativeLayout>

Android Manifest File

The Android Manifest file provides essential information about your app to the Android system in which the system must required before running the code. It describe the overall information about the application. It contains some libraries that needed to access the several method within the app.

<?

xml version=

"1.0"

encoding=

"utf-8"

?>
<

manifest xmlns:

android=

"http://schemas.android.com/apk/res/android"
package

=

"com.razormist.simplelistview"

>
<

application
android:

allowBackup=

"true"
android:

icon=

"@mipmap/ic_launcher"
android:

label=

"@string/app_name"
android:

roundIcon=

"@mipmap/ic_launcher_round"
android:

supportsRtl=

"true"
android:

theme=

"@Style/AppTheme"

>
<

activity android:

name=

".MainActivity"
android:

configChanges=

"orientation"
android:

screenOrientation=

"portrait"

>
<

intent-

filter>
<

action android:

name=

"android.intent.action.MAIN"

/>
<

category android:

name=

"android.intent.category.LAUNCHER"

/>
</

intent-

filter>
</

activity>
</

application>
</

manifest>

The Main Function

This code contains the main function of the application. This code will display all the list that have been store to an array of data. To start with first locate your MainActivity java file and open it, then write these some important variables inside the MainActivity class.

private

ListView

listView;
private

static

String

[

]

LANG =

new

String

[

]

{

"JavaScript"

, "Java"

, "Python"

, "Ruby"

, "PHP"

, "C++"

, "C"

, "Shell"

, "C#"

, "Objective-C"

, "R"

, "Viml"

, "Go"

, "Perl"

, "CoffeScript"

, "TeX"

, "Scala"

, "Haskell"

, "Emacs Lips"

}

;

Then write these several method inside the activity class to make the apps work properly.

void

ListItem(

)

{
listView =

(

ListView

)

findViewById(

R.id

.lv_display

)

;
ArrayAdapter<

String>

adapter =

new

ArrayAdapter<

String>

(

this

,R.layout

.name_list

,LANG)

;
adapter.sort

(

new

Comparator<

String>

(

)

{
@Override
public

int

compare(

String

lhs, String

rhs)

{
return

lhs.compareTo

(

rhs)

;
}
}

)

;
listView.setAdapter

(

adapter)

;
listView.setOnItemClickListener

(

new

AdapterView.OnItemClickListener

(

)

{
@Override
public

void

onItemClick(

AdapterView<?>

parent, View

view, int

position, long

id)

{
String

display =

(

String

)

listView.getItemAtPosition

(

position)

;
Toast.makeText

(

MainActivity.this

, display, Toast.LENGTH_SHORT

)

.show

(

)

;
}
}

)

;
}

Finally, initialize all the methods inside the onCreate method to run the application.

ListItem(

)

;

Try to run the app and see if it worked.
