package com.jay.demo;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class HomeActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layout1);
Button gotoBtn = (Button) findViewById(R.id.gotobtn);
gotoBtn.setOnClickListener(listener);
}
private OnClickListener listener = new OnClickListener() {

@Override
public void onClick(View v) {
Intent intent = new Intent(HomeActivity.this, SecondActivity.class);
startActivityForResult(intent, 0);
// HomeActivity.this.finish();
int version = Integer.valueOf(android.os.Build.VERSION.SDK);
if(version > 5 ){
overridePendingTransition(R.anim.zoomin, R.anim.zoomout);
}
// HomeActivity.this.finish();
}
};
}
