I have an image from ImageView and then i want to set to PDF, so how to use that?

I am new to Android application development. Using iText I had done the PDF creation and write on that created file now I want to create image to PDF from my `ImageView. Here's my code :
public class PdfCreatorActivity extends AppCompatActivity {

I don't know how to implement image can generates to PDF using iText,
Examples will be appreciable...
thanks in advance.

Use PdfDocument to generate pdf form View.
This class enables generating a PDF document from native Android content
Sample code:
// Create a new document
PdfDocument document = new PdfDocument();
// crate a page description
PageInfo pageInfo = new PageInfo.Builder(view.getWidth(), view.getHeight(), 1).create();
// start a page
Page page = document.startPage(pageInfo);
// draw on page
view.draw(page.getCanvas());
// finish the page
document.finishPage(page);
// generate pdf
new PdfGenerationTask().execute();
Use AsyncTask to generate pdf form document
private class PdfGenerationTask extends AsyncTask<Void, Void, File> {
#Override
protected void onPreExecute() {
super.onPreExecute();
}
#Override
protected File doInBackground(Void... params) {
return generatePdf();
}
#Override
protected void onPostExecute(File file) {
/* Dismiss the progress dialog after sharing */
}
}
generatePdf method
private File generatePdf(){
SimpleDateFormat sdf = new SimpleDateFormat("ddMMyyyyhhmmss");
String pdfName = "pdf"
+ sdf.format(Calendar.getInstance().getTime()) + ".pdf";
String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/Pdf";
File dir = new File(path);
if(!dir.exists())
dir.mkdirs();
File file = new File(dir, pdfName);
if( document != null ){
// write the document content
try {
OutputStream out = new FileOutputStream(file);
if( out != null ){
document.writeTo(out);
// close the document
document.close();
out.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
return file;
}
PdfDocument is easy and simple to use. PdfDocument required min sdk 19

Android : How to pass an image from camera or gallery to another fragment?

I have a Bitmap as a general variable to set, but when I run my App, it doesn't show anything.
Here my Code:
public AlertDialog FragmentDialog(){
AlertDialog.Builder builder=new AlertDialog.Builder(getActivity());
LayoutInflater inflater=getActivity().getLayoutInflater();
View view=inflater.inflate(R.layout.imagenfoto,null);
dg_image=view.findViewById(R.id.dlg_image);
dg_image.setImageBitmap(bitmap);
builder.setView(inflater.inflate(R.layout.imagenfoto,null))
.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
//dg_image.setImageBitmap(bitmap);
dialogInterface.cancel();
}
});
return builder.create();
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode== getActivity().RESULT_OK && requestCode==10){
Uri path=data.getData();
foto.setImageURI(path);
}
*/
if(requestCode==CAMARA_REQUEST && resultCode==Activity.RESULT_OK){
Bitmap photo=(Bitmap)data.getExtras().get("data");
bitmap=(Bitmap)data.getExtras().get("data");
foto.setImageBitmap(photo);
Log.d("Debug",bitmap.toString());
//comunicador.setFoto(bitmap);
/*try {
setFoto(photo);
}catch (Exception e){
Log.d("setGaleria:",e.getMessage());
}*/
//cd_imagen.setImageBitmap(photo);
}
//***//
Uri selectedImageUri=null;
Uri selectedImage;
if(requestCode==SELECT_FILE && resultCode==Activity.RESULT_OK){
selectedImage=data.getData();
String selectedPath=selectedImage.getPath();
if(selectedPath != null){
InputStream imageStream=null;
try {
imageStream=getActivity().getContentResolver().openInputStream(
selectedImage);
}catch (FileNotFoundException e){
e.printStackTrace();
}
//Transformamos la URI de la imagen a ImputStream y este a un Bitmap
Bitmap bmp=BitmapFactory.decodeStream(imageStream);
bitmap=BitmapFactory.decodeStream(imageStream);
Log.d("Debug",bitmap.toString());
/*try {
setFoto(bmp);
}catch (Exception e){
Log.d("setGaleria:",e.getMessage());
}*/
//Ponemos nuestro Bitmap en un ImageView que tengamos en la vista
foto.setImageBitmap(bmp);
//comunicador.setFoto(bmp);
//cd_imagen.setImageBitmap(bmp);
}
}
}

you should pass the view on which you have set the bitmap
not the one using new inflator.
don't pass this
builder.setView(inflater.inflate(R.layout.imagenfoto,null))
instead, use the existing view
builder.setView(view)
Final code
public AlertDialog FragmentDialog(){
AlertDialog.Builder builder=new AlertDialog.Builder(getActivity());
LayoutInflater inflater=getActivity().getLayoutInflater();
View view=inflater.inflate(R.layout.imagenfoto,null);
dg_image=view.findViewById(R.id.dlg_image);
dg_image.setImageBitmap(bitmap);
builder.setView(view))
.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
//dg_image.setImageBitmap(bitmap);
dialogInterface.cancel();
}
});
return builder.create();
}

function(element, percentX, percentY){
var tolerance = 0.01; //needed because the rects returned by getBoundingClientRect provide the position up to 10 decimals
if(percentX == null){
percentX = 100;
}
if(percentY == null){
percentY = 100;
}
var elementRect = element.getBoundingClientRect();
var parentRects = [];
while(element.parentElement != null){
parentRects.push(element.parentElement.getBoundingClientRect());
element = element.parentElement;
}
var visibleInAllParents = parentRects.every(function(parentRect){
var visiblePixelX = Math.min(elementRect.right, parentRect.right) - Math.max(elementRect.left, parentRect.left);
var visiblePixelY = Math.min(elementRect.bottom, parentRect.bottom) - Math.max(elementRect.top, parentRect.top);
var visiblePercentageX = visiblePixelX / elementRect.width * 100;
var visiblePercentageY = visiblePixelY / elementRect.height * 100;
return visiblePercentageX + tolerance > percentX && visiblePercentageY + tolerance > percentY;
});
return visibleInAllParents;
};

Cannot Upload Image From Gallery in Android Studio

I want to upload image from gallery in my android app. When I click on button, the gallery should be opened. After selecting image, I want to open another activity named UploadActivity. There the thumbnail of the image should be previewed. The Upload Button will below the thumbnail.
But when I Choose photo from gallery, then the thumbnail of the image are not previewing. I am unable to upload the photo also. My Code goes here: (Scan.Java)
private static final int CAMERA_CAPTURE_IMAGE_REQUEST_CODE = 100;

Here is Logcat:
E/MainActivity: Response from server: java.io.FileNotFoundException: /mnt/sdcard/Pictures/master/IMG_20170127_152930.jpg: open failed: ENOENT (No such file or directory)

File path = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
File file = new File(path, "IMG_20170127_152930.jpg");
//Try this.

After these changes i suggested below I hope your problem will be solved:
Remove these two lines from openGallery() because I think they are redundant.
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
They are needed when we use Intent.ACTION_PICK. So after editing openGallery() looks like:
private void openGallery(){
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Image"),SELECT_IMAGE);
}
Add this statement in your onActivityResult() :
fileUri = data.getData();
so it looks:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
...
else if (requestCode == SELECT_IMAGE)
{
if (resultCode == Activity.RESULT_OK)
{
if (data != null)
{
fileUri = data.getData(); //added this line
launchUploadActivity(true);
}
} else if (resultCode == Activity.RESULT_CANCELED)
{
Toast.makeText(getApplicationContext(), "Cancelled", Toast.LENGTH_SHORT).show();
}
}
}
Same applies to the camera intent also.
Request EXTERNAL_STORAGE permission and also run time permission if your target Android version is 6.0 or above.
EDIT:
Sorry couple of things I have not mentioned those are required are given bellow:
You may like to send the Uri instead of path this way:
private void launchUploadActivity(boolean isImage){
Intent i = new Intent(this, UploadActivity.class);
i.setData(fileUri);
// i.putExtra("filePath", fileUri.getPath());
i.putExtra("isImage", isImage);
startActivity(i);
}
And then in UploadActivity do the following:
...
private InputStream mInputStream; // Use this stream to create bitmap and upload to server
#Override
protected void onCreate(Bundle savedInstanceState) {
...
// Receiving the data from previous activity
Intent i = getIntent();
try {
mInputStream = getContentResolver().openInputStream(i.getData());
} catch (FileNotFoundException e) {
e.printStackTrace();
}
...
}
...
...
private void previewMedia(boolean isImage){
if (isImage) {
imgPreview.setVisibility(View.VISIBLE);
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 8;
Bitmap bitmap = BitmapFactory.decodeStream(mInputStream,null,options);
imgPreview.setImageBitmap(bitmap);
} else {
imgPreview.setVisibility(View.GONE);
}
}
...
This works for me and hope will work on you too.

Activity associated with image cropping libraries does not destroy

I have tried to solve this problem from many different links but does not worked for me.I am using Android Image Cropper library for cropping images. Whenever i click on the button "upload image" it start the cropping activity and when i am done the cropped image is set in an imageview in "upload image" activity and after clicking "Proceed" button login is successful and i am directed to login activity but when i back press the login activity the "Upload image" activity is still there and is not destroyed. I have another activity called Update Activity that uses this Cropping activity and that activity also behaves in the same manner. So i want the "Upload image" to destroy. Thanks in advance
