Well i made this and it works for me
*This is the manifest file*
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android";
package="pas.Hari.com"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="@drawable/icon"
android:label="@string/app_name">
<activity android:name=".TestHari"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".DetList"/>
</application>
<uses-sdk android:minSdkVersion="4" />
</manifest>
*THis is the DetList class*
package pas.Hari.com;
import android.app.Activity;
import android.os.Bundle;
public class DetList extends Activity{
String i1;
String i2;
String i3;
String i4;
String i5;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.details);
}
}
*And this is the TestHari class*
package pas.Hari.com;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class TestHari extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button yes=(Button)findViewById(R.id.yes);
yes.setOnClickListener(onYes);
}
private View.OnClickListener onYes=new View.OnClickListener()
{
public void onClick(View v)
{
Intent i=new Intent(TestHari.this, DetList.class);
startActivity(i);
}
};
}
