        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();
