如何在手机图库中添加Sqlite数据库中的图像？ [英] How to add image in Sqlite database from phone gallery?

问题描述

这是我从库中获取数据的代码，并将其保存在SQLite数据库中，但它无法正常工作

This is my code to get data from gallery and save it in SQLite database but its not working

    .....

    case PICK_FROM_GALLERY:     
        Bundle extras2 = data.getExtras();
        if (extras2 != null) {
            Bitmap yourImage = extras2.getParcelable("data");
            // convert bitmap to byte
            ByteArrayOutputStream stream = new ByteArrayOutputStream();
            yourImage.compress(Bitmap.CompressFormat.PNG, 100, stream);
            byte imageInByte[] = stream.toByteArray();
            Log.e("output before conversion", imageInByte.toString());
            // Inserting Contacts
            Log.d("Insert: ", "Inserting ..");
            db.addContact(new Contact(resultCode, "Android", imageInByte));
            Intent i = new Intent(Editor.this, Editor.class);
            startActivity(i);
            finish();
        }
        break;
    }
}

推荐答案

存储图像的Uri，通过Uri，您可以在ImageView中设置图像

   Uri imageUri;

   Intent pickUpImage = new Intent(Intent.ACTION_PICK);
            pickUpImage.setType("image/*");
            startActivityForResult(pickUpImage, 1);

  @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == 1 && resultCode == Activity.RESULT_OK) {
            Uri uri = data.getData();
            imageUri = uri;
            profilePic.setImageURI(imageUri);

        }
    }
