Insert Image into PDF Document - image

Question

Is it possible to add an image to the PDF document? My layout has one (Button) and one (ImageView), I would like that when I click (Button), it will open the Gallery to select the image, show it in (ImageView) and add it to the PDF document, as if it were a generator curriculum, thank you in advance.

here is the complete code of what you wanted. Try this and let me know.
In the onCreate method:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_image_to_pdf);
imageView = findViewById(R.id.imageView);
galleryBtn = findViewById(R.id.gallery);
convertBtn = findViewById(R.id.convert);
galleryBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.getDefault()).format(new Date());
String imageFileName = "PDF_" + timeStamp + "_";
File storageDir = getAlbumDir();
try {
pdfPath = File.createTempFile(
imageFileName, /* prefix */
".pdf", /* suffix */
storageDir /* directory */
);
} catch (IOException e) {
e.printStackTrace();
}
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(photoPickerIntent, GALLERY_INTENT);
}
});
convertBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (bitmap == null) {
Toast.makeText(ImageToPDF.this, "Please select the image from gallery", Toast.LENGTH_LONG).show();
} else {
convertToPDF(pdfPath);
}
}
});
}
Create a directory for PDF file:
private File getAlbumDir() {
File storageDir = null;
if (Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState())) {
storageDir = new File(Environment.getExternalStorageDirectory()
+ "/dcim/"
+ "Image to pdf");
if (!storageDir.mkdirs()) {
if (!storageDir.exists()) {
Log.d("CameraSample", "failed to create directory");
return null;
}
}
} else {
Log.v(getString(R.string.app_name), "External storage is not mounted READ/WRITE.");
}
return storageDir;
}
On camera activity intent result:
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == GALLERY_INTENT) {
if (resultCode == Activity.RESULT_OK && data != null) {
Uri selectedImage = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
if (selectedImage != null) {
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
if (cursor != null) {
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String imagePath = cursor.getString(columnIndex);
bitmap = BitmapFactory.decodeFile(imagePath);
imageView.setImageBitmap(bitmap);
cursor.close();
}
}
} else if (resultCode == Activity.RESULT_CANCELED) {
Log.e("Canceled", "Image not selected");
}
}
}
Now code to convert image to PDF and save to the directory:
private void convertToPDF(File pdfPath) {
int width = bitmap.getWidth();
int height = bitmap.getHeight();
PdfDocument pdfDocument = new PdfDocument();
PdfDocument.PageInfo pageInfo = new PdfDocument.PageInfo.Builder(width, height, 1).create();
PdfDocument.Page page = pdfDocument.startPage(pageInfo);
Canvas canvas = page.getCanvas();
Paint paint = new Paint();
paint.setColor(Color.parseColor("#ffffff"));
canvas.drawPaint(paint);
bitmap = Bitmap.createScaledBitmap(bitmap, width, height, true);
paint.setColor(Color.BLUE);
canvas.drawBitmap(bitmap, 0, 0, null);
pdfDocument.finishPage(page);
try {
pdfDocument.writeTo(new FileOutputStream(pdfPath));
Toast.makeText(ImageToPDF.this, "Image is successfully converted to PDF", Toast.LENGTH_LONG).show();
} catch (IOException e) {
e.printStackTrace();
}
pdfDocument.close();
}
