How do I convert an image to a String to read/write it to a SQLite Database - Android Studio (Java)

I am having trouble converting an image to a String to read/write it to a SQLite Database on Android Studio using Java. I have watch loads of tutorials and cannot seem to find what I am missing. Any help at all would be appreciated!!

You need to convert mImageView. to a byte[] (bitmap).
So
BitmapDrawable d = (BitmapDrawable) mImageView.getDrawable();
Bitmap b = d.getBitmap();
boolean isInserted = myDb.insertData(editTitle.getText().toString(), editDescription.getText().toString(),
editOwner.getText().toString(), b);
If bitmap larger than 2Mb then cannot be got from Cursor. It is not advised to store bitmap in database but to store bitmap as file and to store path in database.

How to pass data from return activity to dialog in previous activity?

Visitor Details
I have a dialog in Visitor Activity. When I click on the icon, it will redirect to Camera Activity. Then when click Confirm button in Camera Activity, it will send the intent back to previous Activity which is Visitor Activity. The problem is how should I pass the intent result from Camera Activity back to the dialog in Visitor Activity. The intent data should be placed in the Pass No Edit Text. I'm using material dialog without any Fragment that attached to that dialog. It all placed in Visitor Activity. Can someone please help me? Thank you!
private void checkin()
{
final MaterialDialog dialog = new MaterialDialog.Builder(VisitorDetailActivity.this)
.customView(R.layout.sample,false)
.build();
View view = dialog.getCustomView();
final EditText etPassNo = (EditText) view.findViewById(R.id.etPassNo);
final EditText etVehicleNo = (EditText) view.findViewById(R.id.etVehicleNo);
final ImageView ivScanCode = (ImageView) view.findViewById(R.id.ivScanCode);
final TextView tvCancel = (TextView) view.findViewById(R.id.tvCancel);
final TextView tvSubmit = (TextView) view.findViewById(R.id.tvSubmit);
etVehicleNo.setText(model.getFldVehicleNo());
if(barCode != null)
{
etPassNo.setText(barCode);
}
ivScanCode.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
//Toast.makeText(VisitorDetailActivity.this, "Bar code scanner", Toast.LENGTH_SHORT).show();

dialog.show();
}
#Override

First you need to take the view object globally out of that checkIn methoed
View view;
view = dialog.getCustomView();
final EditText etPassNo = (EditText) view.findViewById(R.id.etPassNo);
Now under your onActivityResult method, as i can see you already getting the barcode there, so just initiate the EditText object again on that same simply set the data in it.
barCode = data.getStringExtra("barCode");
EditText etPassNo = (EditText) view.findViewById(R.id.etPassNo);
etPassNo.setText(barCode);
Let me know if that works.

you can do it using interface
public interface OnBarcodeSelect{
void onBarcodeSelected(String barcode);}
OnBarcodeSelect onBarcodeSelect;
private void checkin()
{
final MaterialDialog dialog = new MaterialDialog.Builder(VisitorDetailActivity.this)
.customView(R.layout.sample,false)
.build();
View view = dialog.getCustomView();
final EditText etPassNo = (EditText) view.findViewById(R.id.etPassNo);
final EditText etVehicleNo = (EditText) view.findViewById(R.id.etVehicleNo);
final ImageView ivScanCode = (ImageView) view.findViewById(R.id.ivScanCode);
final TextView tvCancel = (TextView) view.findViewById(R.id.tvCancel);
final TextView tvSubmit = (TextView) view.findViewById(R.id.tvSubmit);
etVehicleNo.setText(model.getFldVehicleNo());
if(barCode != null)
{
etPassNo.setText(barCode);
}
ivScanCode.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
//Toast.makeText(VisitorDetailActivity.this, "Bar code scanner", Toast.LENGTH_SHORT).show();
Intent i = new Intent(VisitorDetailActivity.this, ScanCodeActivity.class);
onBarcodeSelect = new OnBarcodeSelect() {
#Override
public void onBarcodeSelected(String barcode) {
//handle barcode here
etPassNo.setText(barcode);
}
}
startActivityForResult(i,97);
}
});
tvCancel.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
dialog.dismiss();
}
});
tvSubmit.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
if(etPassNo.getText().toString().trim().isEmpty())
{
Toast.makeText(VisitorDetailActivity.this, "Pass No is required", Toast.LENGTH_SHORT).show();
return;
}
if(selImage == null)
{
proceedCheckin(etPassNo.getText().toString(), etVehicleNo.getText().toString());
}
else
{
proceedCheckinImage(etPassNo.getText().toString(), etVehicleNo.getText().toString());
}
}
});
dialog.show();
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == 98 && resultCode == RESULT_OK)
{

In your onLoadFinished you assume mPictureURI is set and is not empty.
Now you have set a listener on mProductImageView for changes. No matter what you write/set down below the mProductImageView finally the in the listener it was set back to mPictureURI which was empty hence showing an empty image space.
Please have a look at the code below(also verified that it works).
#Override
public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {
if (cursor == null || cursor.getCount() < 1) {
return;
}
if (cursor.moveToFirst()) {
int nameColumnIndex = cursor.getColumnIndex(ProductContract.ProductEntry.COLUMN_PRODUCT_NAME);
int priceColumnIndex = cursor.getColumnIndex(ProductContract.ProductEntry.COLUMN_PRODUCT_PRICE);
int quantityColumnIndex = cursor.getColumnIndex(ProductContract.ProductEntry.COLUMN_PRODUCT_QUANTITY);
int supplierColumnIndex = cursor.getColumnIndex(ProductContract.ProductEntry.COLUMN_PRODUCT_SUPPLIER);
int mailColumnIndex = cursor.getColumnIndex(ProductContract.ProductEntry.COLUMN_PRODUCT_SUPPLIER_MAIL);
int pictureColumnIndex = cursor.getColumnIndex(ProductContract.ProductEntry.COLUMN_PRODUCT_PICTURE);
String name = cursor.getString(nameColumnIndex);
String price = cursor.getString(priceColumnIndex);
int quantity = cursor.getInt(quantityColumnIndex);
String supplier = cursor.getString(supplierColumnIndex);
String mail = cursor.getString(mailColumnIndex);
stringUri = cursor.getString(pictureColumnIndex);
mPictureUri = Uri.parse(stringUri);
mNameEditText.setText(name);
mPriceEditText.setText(price);
mQuantityEditText.setText(String.valueOf(quantity));
mSupplierEditText.setText(supplier);
mMailEditText.setText(mail);
}
ViewTreeObserver viewTreeObserver = mProductImageView.getViewTreeObserver();
viewTreeObserver.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
mProductImageView.getViewTreeObserver().removeOnGlobalLayoutListener(this);
if(mPictureUri !=null) {
mProductImageView.setImageBitmap(getBitmapFromUri(mPictureUri, mContext, mProductImageView));

Replace the original image on a new image in android application

In this MainActivity java class on Android Application Project I can't replace the original image given by the system with the one different selected from the photo gallery of smartphone.
When I select the one different photo I have always the original image.
public class MainActivity extends Activity implements OnClickListener {
Button uploadButton, btnselectpic;
ImageView imageview;
private ProgressDialog dialog = null;
private String imagepath = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
uploadButton = (Button) findViewById(R.id.uploadButton);
btnselectpic = (Button) findViewById(R.id.btnselectpic);
imageview = (ImageView) findViewById(R.id.imageview);
btnselectpic.setOnClickListener(this);
uploadButton.setOnClickListener(this);
#Override
public void onClick(View arg0) {
if (arg0 == btnselectpic) {
selectImage();
} else if (arg0 == uploadButton) {
dialog = ProgressDialog.show(MainActivity.this, "",
"Uploading file...", true);
messageText.setText("uploading started.....");
new Thread(new Runnable() {
public void run() {
}
}).start();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1 && requestCode == 2 && resultCode == RESULT_OK) {
Uri selectedImageUri = data.getData();
imagepath = getPath(selectedImageUri);
Bitmap bitmap = BitmapFactory.decodeFile(imagepath);
imageview.setImageBitmap(bitmap);
messageText.setText("Uploading file path:" + imagepath);
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(uri, projection, null, null,
null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
private void selectImage() {
final CharSequence[] options = { "Take Photo", "Choose from Gallery",
"Cancel" };
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("Add Photo!");
builder.setItems(options, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int item) {
if (options[item].equals("Take Photo")) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment
.getExternalStorageDirectory(), "temp.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
startActivityForResult(intent, 1);
} else if (options[item].equals("Choose from Gallery")) {
Intent intent = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 2);
} else if (options[item].equals("Cancel")) {
dialog.dismiss();
}
}
});
builder.show();
}

The problem is that your onActivityResult() will never do anything.
You start this method off with:
if (requestCode == 1 && requestCode == 2 && resultCode == RESULT_OK) {
// ...
}
requestCode cannot be both 1 and 2, so this conditional will always be false.
You are likely looking for something more like this:
if ((requestCode == 1 && resultCode == RESULT_OK) ||
(requestCode == 2 && resultCode == RESULT_OK)) {
// ...
}
