don't forget to add activity in manifest

XML

<activity android:name=".yourPageName.class" xmlns:android="#unknown" />

Put Intent as

Intent firstpage=new Intent(getApplicationContext(),yourPageName.class);
    startActivity(firstpage);

Hi,

I am beginner to the Java programming and android ...I am trying to create an app convertor which has 4-5 conversion money convertor, kgs to pound convertor..So, when I click on one conversion button it has to take me to the page pertaining to calculating the values....

Actually before i had made an app which converts rupees to dollars..I am try use the same xml and java files here...I read tutorial and watched youtube and tried tht in my sdk but its not opening up anything so I do not which part is wrong or I made any mistakes in coding.. If any one out there can help it would be great.

My code goes like this....MainActivity.java

package com.example.converts;

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;

import android.view.View;
import android.widget.Button;


public class MainActivity extends Activity implements View.OnClickListener
{
 Button button2;
@Override
public void onCreate(Bundle savedInstanceState) {
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity1);
button2=(Button)findViewById(R.id.button2);
button2.setOnClickListener(new View.OnClickListener() {
           
public void onClick(View v){
            
if(v.getId()==R.id.button2)
 
{
startActivity(new Intent("com.example.converts.Main1"));
}}
            });
            
}       
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
}}

My Main1 which I created has

package com.example.converts;


import android.os.Bundle;
import android.app.Activity;
import android.content.DialogInterface;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.*;

public class Main1 extends Activity implements OnClickListener {
TextView dollars;
TextView euros;
    RadioButton dtoe;
    RadioButton etod;
Button calculate;
      
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void onClick(DialogInterface arg0, int arg1) {
// TODO Auto-generated method stub



dollars = (TextView)this.findViewById(R.id.dollars);
    euros = (TextView)this.findViewById(R.id.euros);
    
    dtoe = (RadioButton)this.findViewById(R.id.dtoe);
    
    etod = (RadioButton)this.findViewById(R.id.etod);
    
    calculate = (Button)this.findViewById(R.id.calculate);
    calculate.setOnClickListener(this);
}

public void onClick(View v) {
if (dtoe.isChecked()) {
convertDollarsToEuros();
}
if (etod.isChecked()) {
convertEurosToDollars();
}
}

protected void convertDollarsToEuros() {
double val = Double .parseDouble(dollars.getText().toString());
// in a real app, we'd get this off the 'net
euros.setText(Double .toString(val*0.67));
} 

protected void convertEurosToDollars() {
double val = Double .parseDouble(euros.getText().toString());
// in a real app, we'd get this off the 'net
dollars.setText(Double.toString(val/0.67));


}

}

Put this code inside your onClick(){}...It should work..If not,let me know.

C#

if(v.getId()==R.id.button_id)
{
    Intent firstpage=new Intent(this,yourPageName.class);

Thanks...

I tried the codes which are mentioned in the solutions.. no error but No desired output.. on button's click event next page does not open .. dont know where am I missing the step..

I made a new class named SecondPage.java and new activity where i want to jump named activity_main.xml.

I put following code in manifest file within application tag...

< activity android:name=".SecondPage.class" />

In java file I put this piece of code

protected void onCreate(Bundle icicle) {
super.onCreate(icicle);

setContentView(R.layout.new1);

final Button button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new View.OnClickListener() {

public void onClick(View v) {

if(v.getId()==R.id.button1)
{
Intent intent = new Intent(this, SecondPage.class);
startActivity(intent);
}
}
});
}

In SecondPage.java I put following code

public class SecondPage extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

}

public void onClick(DialogInterface arg0, int arg1) {
// TODO Auto-generated method stub

}
}

....................
Please guide me where i am wrong???

Ok Android uses Intent short for intention
An intent is an abstract description of an operation to be performed. It can be used with startActivity to launch an Activity, broadcastIntent to send it to any interested BroadcastReceiver components, and startService(Intent) or bindService(Intent, ServiceConnection, int) to communicate with a background Service.

An Intent provides a facility for performing late runtime binding between the code in different applications. Its most significant use is in the launching of activities, where it can be thought of as the glue between activities. It is basically a passive data structure holding an abstract description of an action to be performed.
Click here for more info about intent
http://developer.android.com/reference/android/content/Intent.html[^]
Now about your question you could use this code snippet

Intent intent = new Intent(this, YourActivity.class);
startActivity(intent);

Open new page on button's click event in android eclips
