ANDROID - 在数据库中保存多个图像

Question

我有一个应用程序，我必须将部分衣服组合在一起。为了更好地理解我，我在下面给出了截图。问题是，我遇到了如何获取这些图像并将其保存在我的数据库中的问题。当然我遇到了错误。

public class ViewOutfit extends Activity {

private DatabaseHandler handler;


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

    Intent i = getIntent();

    final ImageView im1 = (ImageView) findViewById(R.id.im1);
    im1.setImageBitmap(BitmapFactory.decodeFile(i.getStringExtra("image1")));
    im1.toString();

    final ImageView im2 = (ImageView) findViewById(R.id.im2);
    im2.setImageBitmap(BitmapFactory.decodeFile(i.getStringExtra("image2")));
    im2.toString();

    final ImageView im3 = (ImageView)findViewById(R.id.im3);
    im3.setImageBitmap(BitmapFactory.decodeFile(i.getStringExtra("image3")));
    im3.toString();

    final ImageView im4 = (ImageView)findViewById(R.id.im4);
    im4.setImageBitmap(BitmapFactory.decodeFile(i.getStringExtra("image4")));
    im4.toString();

    final ImageView im5 = (ImageView)findViewById(R.id.im5);
    im5.setImageBitmap(BitmapFactory.decodeFile(i.getStringExtra("image5")));
    im5.toString();

    final ImageView im6 = (ImageView)findViewById(R.id.im6);
    im6.setImageBitmap(BitmapFactory.decodeFile(i.getStringExtra("image6")));
    im6.toString();



    ImageButton btn_save_outfit = (ImageButton)findViewById(R.id.btn_combine);
    btn_save_outfit.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            im1.getDrawable().toString();
            im2.getDrawable().toString();
            im3.getDrawable().toString();
            im4.getDrawable().toString();
            im5.getDrawable().toString();
            im6.getDrawable().toString();


            Outfits outfits = new Outfits();
            outfits.setImage1(String.valueOf(im1));
            outfits.setImage2(String.valueOf(im2));
            outfits.setImage3(String.valueOf(im3));
            outfits.setImage4(String.valueOf(im4));
            outfits.setImage5(String.valueOf(im5));
            outfits.setImage6(String.valueOf(im6));

            Boolean added = handler.addOutfit(outfits);
            if(added){
                Toast.makeText(getApplicationContext() , "Outfit added." , Toast.LENGTH_LONG).show();

                String log = "Id: "+ outfits.getID()+" ,Image1: " + outfits.getImage1() + " ,Image2: " + outfits.getImage2()

                        + ",Image3:" + outfits.getImage3() + ",Image4:" + outfits.getImage5() + ",Image6:" +outfits.getImage6();

                Log.d("Image1: ", log);


            }else{
                Toast.makeText(getApplicationContext(), "Outfit not added. Please try again", Toast.LENGTH_LONG).show();
            }


        }});
}
