How To Create Absolute Layout in an Android Application

In this Tutorial, you will Learn How to create Absolute Layout

Here you go!!!!

Before creating an android application using Eclipse, let us see some of the key terms involved while developing this application.

Key terms involved in this project:

Absolute Layout: The AbsoluteLayout lets you specify the exact location of its children. The location of the views (children of layout while writing activity.xml) can be specified using attributes layout x and layout y both values are mentioned in DP. Absolute positioning is not too much useful in world of various screen resolutions and aspect ratios. You’d usually leave element positioning to be computed by more flexible layouts.

The tutorial is about how to display an activity in absolute layout.

This project is developed in Eclipse 4.2 (Juno) and tested with Android 2.2

Coding:

Now let’s go to the coding section. This project requires following files.

Source Code:

1. Absolutelayout.java (Activity in absolutelayout)

Activity Files:

1. activity_absolutelayout.xml -€“ absolutelayout activity

res – Values:

1. strings.xml -€“ strings available in absolute layout

Manifest file:

1. AndroidManifest.xml

Here is the coding for the above files.

Absolutelayout.java:

package com.example.absolutelayout; //Package absolutelayout
import android.os.Bundle;  //A mapping from String values to various Parcelable types.
import android.app.Activity; // Required to create an activity.
import android.view.Menu; // Interface for managing the items in a menu.
public class Absolutelayout extends Activity { // all classes extends activity
	@Override
	protected void onCreate(Bundle savedInstanceState) {// Create an activity/ screen
		super.onCreate(savedInstanceState);
// displays activity absolutelayout in absolute layout when app starts
		setContentView(R.layout.activity_absolutelayout);
	}
	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.activity_absolutelayout, menu);
		return true;
	}
}

activity_absolutelayout.xml:

Menu : activity_absolutelayout.xml

AndroidManifest.xml:

strings.xml:

    Absolutelayout
    
    Settings

Styles. xml:

Run the android application:

Android applications can be run on the android devices. You can either connect hardware to the system to test the application or you can use the android virtual devices (AVD) Manager to create/manage the virtual devices running on emulator to run the application.

If you are new to create a Android Virtual Device (AVD), refer Creating Android Virtual Device.

To run the application/ project, Build your project using Project –>  Build Project.

This will show errors in Console window at the bottom of the working area in case your project contains.

If your build is successful, Run your application using Run –>  Run or Press Ctrl +F11.

Upon running the application, the emulator will be launched which displays the AVD on your screen.

You can see your app with the image set during the android project creation in AVD. Upon running the application, the emulator will be launched with the selected/ available AVD created on your screen.

To test your application, unlock the screen and double click on your app.

Thus the android application project is executed successfully.
