This example prints alphabets from a name after an interval of 5 seconds each using timer threads.
Algorithm:
1.) Create a new project by File-> New -> Android Project name it TimerThreadExample.
1.) Create a new project by File-> New -> Android Project name it TimerThreadExample.
2.) Write following into main.xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:padding="@dimen/padding_medium"
tools:context=".TimerThreadExample"
android:textSize="40pt" />
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:padding="@dimen/padding_medium"
tools:context=".TimerThreadExample"
android:textSize="40pt" />
</RelativeLayout>
3.) Run for output.
Steps:
1.) Create a project named TimerThreadExample and set the information as stated in the image.
Build Target: Android 4.0
Application Name: TimerThreadExample
Package Name: com. example. TimerThreadExample
Activity Name: TimerThreadExample
Min SDK Version: 8
Application Name: TimerThreadExample
Package Name: com. example. TimerThreadExample
Activity Name: TimerThreadExample
Min SDK Version: 8
2.) Open TimerThreadExample.java file and write following code there:
package com.example.timerthreadexample;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.widget.TextView;
import android.os.Bundle;
import android.view.Menu;
import android.widget.TextView;
public class TimerThreadExample extends Activity {
protected int splashTime = 3000;
TextView tv1;
String[] name = {"A","N","D","R","O","I","D"};
int timer =0;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tv1 = (TextView) findViewById(R.id.textView1);
Thread th=new Thread(){
TextView tv1;
String[] name = {"A","N","D","R","O","I","D"};
int timer =0;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tv1 = (TextView) findViewById(R.id.textView1);
Thread th=new Thread(){
@Override
public void run(){
try
{
for (timer = 0; timer < 7; timer++)
{
int waited = 0;
while(waited < splashTime)
{
Thread.sleep(100);
runOnUiThread(newRunnable() {
@Override
public void run(){
try {
tv1.setText(name[timer]);
}
catch(Exception e)
{
e.printStackTrace();
}
}
});
waited += 100;
}
}
}catch (InterruptedException e) {
}
public void run(){
try
{
for (timer = 0; timer < 7; timer++)
{
int waited = 0;
while(waited < splashTime)
{
Thread.sleep(100);
runOnUiThread(newRunnable() {
@Override
public void run(){
try {
tv1.setText(name[timer]);
}
catch(Exception e)
{
e.printStackTrace();
}
}
});
waited += 100;
}
}
}catch (InterruptedException e) {
}
}
};
th.start();
}
};
th.start();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
3.) Compile and build the project.
Output
