EX.NO. 1 DEVELOP AN APPLICATION THAT USES GUI COMPONENTS, LAYOUT
MANAGERS AND EVENT LISTENERS.

AIM:

To develop an application that uses GUI components, layout managers and event listeners.

PROCEDURE:
1) Open android studio and select new android project
2) Give project name and package name.
3) UI design for android application is done using a layout xml file. Android studio offers a layout editor
which allows you to drag and drop UI elements into the interface.
4) Create the activity_main.xml file and MainActivity.java file
5) Run the application
package com.example.font1;
import android.graphics.Color;
import android.support.v7.app.AppCompatActivity; import
android.os.Bundle;
import android.view.View; import
android.widget.Button; import
android.widget.TextView;
public class MainActivity extends AppCompatActivity
{
int ch=1; float
font=30;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState); setContentView(R.layout.activity_main);
final TextView t= (TextView) findViewById(R.id.textView); Button
b1= (Button) findViewById(R.id.button); b1.setOnClickListener(new
View.OnClickListener() {
@Override
public void onClick(View v) {
t.setTextSize(font); font =
font + 5;
if (font == 50)
font = 30;
}
});
Button b2= (Button) findViewById(R.id.button2);
b2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
switch (ch) {
case 1:
t.setTextColor(Color.RED); break;
case 2:
t.setTextColor(Color.GREEN);
break;
case 3:
t.setTextColor(Color.BLUE); break;

case 4:
t.setTextColor(Color.CYAN); break;
case 5:
t.setTextColor(Color.YELLOW);
break;
Event Listeners
Two most commonly used event listeners – onClickEventListener() and
onLongClickEventListener(). Step 1:

First we need to define some variables for each items in the UI.
Button clickBtn, longClickBtn, allBtn, btnShow;
TextView sample;
EditText nameTxt;

Step 2:
Assign the UI elements to these variables using findViewById()
clickBtn = (Button) findViewById(R.id.btnClick);
longClickBtn = (Button) findViewById(R.id.btnLongClick);
allBtn = (Button) findViewById(R.id.btnAll);
btnShow = (Button) findViewById(R.id.btnShowName);
sample = (TextView) findViewById(R.id.txtSample);
nameTxt = (EditText) findViewById(R.id.txtName);

Step 3:
Implementing the onClick Listener:
/*Simple Click onClick Listener*/
clickBtn.setOnClickListener(new View.OnClickListener()
{ @Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(), "Hai John!", Toast.LENGTH_SHORT).show();
}
});
This event listener toasts a message Hai John when the “Click Me!” button is clicked

Step 4:
Implementing the onLongClick Listener
/*Implement Long Click Listener*/
longClickBtn.setOnLongClickListener(new View.OnLongClickListener() {
@Override
public boolean onLongClick(View v)
{ Toast.makeText(getApplicationContext(), "Hai
there!", Toast.LENGTH_SHORT).show();
return false;
}
});
This
event listener toasts a message “Hai there!” when the “Long Click Me!” button is clicked and held.

Step 5:
Implementing onClick and onLongClick Event on the same button.
allBtn.setOnClickListener(new View.OnClickListener()
{ @Override
public void onClick(View v)
{ Toast.makeText(getApplicationContext(), "You Just Clicked
Me!", Toast.LENGTH_SHORT).show();
}
});
allBtn.setOnLongClickListener(new View.OnLongClickListener()
{ @Override
public boolean onLongClick(View v)
{ Toast.makeText(getApplicationContext(), "You clicked me for so
long!", Toast.LENGTH_SHORT).show();
return false;
}
});
The button defined by the variable allBtn will toast two different messages when clicked
and longclicked
i.e, “You just Clicked Me!” when clicked and “You clicked me for so long!”
when long clicked.
Step 6:
Reading a data from a text field and writing it to a text view using event listeners.
btnShow.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
sample.setText(nameTxt.getText().toString());
}
});
This event reads the value of the nameTxt text field and writes it to sample TextView.

RESULT:
Thus the program to create a Mobile App to display GUI components anddifferent layouts is executed
successfully.
EX.NO.3 DEVELOP AN APPLICATION THAT DRAWS BASIC
GRAPHICAL PRIMITIVES
AIM:

To develop an application that draws basic graphical primitives on the screen in android.

PROCEDURE:

activity_main.xml:
<RelativeLayout

<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:src="@drawable/ic_launcher"
tools:ignore="ContentDescription" />

</RelativeLayout>

MainActivity.java:
public package com.example.ex_no_3;
import android.support.v7.app.ActionBarActivity;
import android.annotation.SuppressLint;
import android.graphics.Bitmap;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.os.Bundle;
import android.view.Display;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.widget.ImageView;
@SuppressLint("ClickableViewAccessibility")
public class MainActivity extends ActionBarActivity implements
OnTouchListener{

ImageView iv;
Bitmap b;
Canvas c;
Paint p;
float dx=0,dy=0,ux=0,uy=0;
@SuppressWarnings("deprecation")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
iv=(ImageView)this.findViewById(R.id.imageView1);

Display d = getWindowManager().getDefaultDisplay();
float dw = d.getWidth();
float dh = d.getHeight();
b = Bitmap.createBitmap((int) dw, (int)
dh,Bitmap.Config.ARGB_8888);
c = new Canvas(b);
p = new Paint();
p.setColor(Color.BLUE);
iv.setImageBitmap(b);
iv.setOnTouchListener(this);
}
@Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
int action = event.getAction();
switch (action){
case MotionEvent.ACTION_DOWN:
dx =event.getX();
dy= event.getY();
break;
case MotionEvent.ACTION_MOVE:
break;
case MotionEvent.ACTION_UP:
ux = event.getX();
 uy = event.getY();
c.drawLine(dx, dy, ux, uy, p);
iv.invalidate();
break;
case MotionEvent.ACTION_CANCEL:
break;
default:
break;
}
}
return true;
}

RESULT: Thus a Mobile App has been developed to display all the graphics primitives and seen in the
Android Emulator.
EX NO: 4 DEVELOP AN APPLICATION THAT MAKES USE OF
DATABASE
AIM:

To develop an application that makes use of database.

PROCEDURE:

We will use the SQLiteDatabase and SQLiteOpenHelper classes to implement database handling.
Creating database handler class
To handle a database we need to create a database handler class.
So, right click on the package directory (inside java folder) and select New then Java Class

Name it for example MyDBHandler

Now we need to extend the SQLiteOpenHelper class Now these methods are automatically generated for you

Declare some static variables that will save the database and the table details we are going to create.

PROCEDURE:

1. Open eclipse or android studio and select new android project

2. Give project name and select next

3. Choose the android version.Choose the lowest android version(Android 2.2) and select
next

4. Enter the package name.package name must be two word seprated by comma and click
finish
5. Go to package explorer in the left hand side.select our project.
6. Go to res folder and select layout. Double click the main.xml file. Add the code

7. Now select mainactivity.java file and type the following code.In my coding
maniactivity name is Alert1Activity .

8. Now go to main.xml and right click .select run as option and select run configuration

EXNO: 10 DEVELOP AN APPLICATION TO BUILD AN ALARM CLOCK.

.
AIM:

To develop a Android Application that creates Alarm Clock.

PROCEDURE:

Creating a New project:

 Open Android Studio and then click on File -> New -> New project.

 Then type the Application name as “ex.no.11″ and click Next.

 Then select the Minimum SDK as shown below and click Next.
 Then select the Empty Activity and click Next.
 Finally click Finish.
 It will take some time to build and load the project.
