package com.example.udpshop;

import android.os.Bundle;
import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageView;

public class Main extends Activity {

private databse db;
private EditText et;
private ImageView ie;
private Button bt;


protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
et=(EditText) findViewById(R.id.editText1);
ie=(ImageView) findViewById(R.id.imageView1);
bt=(Button) findViewById(R.id.btn1);
db=new databse(this);

db.database();
bt.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View arg0) {
db.open();
byte[] p=db.getpic(Integer.parseInt(et.getText().toString ()));
if(p!=null){
Bitmap bm=BitmapFactory.decodeByteArray(p, 0, p.length);
ie.setImageBitmap(bm);

}else{

}
db.close();
}

});


}
