How to make a floating button disappear android? - java

I have a simple floating button that open the camera and then display the image in the Main Activity.
I want to remove that floating button right after the user retrieve the image result so It should be onActivityResult right after scannedImageView.setImageBitmap(bitmap)
I tried using btnFloat.setVisibility(View.GONE); but since it's a floating button I do not know how to call it on my method.
MainActivity
ImageView scannedImageView;
public void init() {
FloatingActionButton fab = findViewById(R.id.fab_capture);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK && data != null) {
if (requestCode == OPEN_THING) {
Uri uri = data.getExtras().getParcelable(ScanConstants.SCANNED_RESULT);
Bitmap bitmap = null;
try {
bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
getContentResolver().delete(uri, null, null);
scannedImageView.setImageBitmap(bitmap);
//btnFloat.setVisibility(View.GONE);
FileOutputStream outputStream = null;
File sdCard = new File(getExternalFilesDir(null).getAbsolutePath());
File directory = new File (sdCard.getAbsolutePath() +"/Scan Documents");
directory.mkdir();
String filename = String.format("d.jpg", System.currentTimeMillis());
File outFile = new File(directory, filename);
Toast.makeText(this, "Image Saved Successfully", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
intent.setData(Uri.fromFile(outFile));
sendBroadcast(intent);
try{
outputStream = new FileOutputStream(outFile);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outputStream);
outputStream.flush();
outputStream.close();
}catch (FileNotFoundException e)
{
e.printStackTrace();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
}

make FloatingActionButton a Global member variable then you can access
it in onActivityResult
public class MyActivity extends Activity {
...
FloatingActionButton fab;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
fab = findViewById(R.id.fab_capture);
}
protected void onActivityResult(int requestCode, int resultCode,
Intent data) {
...
fab.hide();
...
}
}

Save image to a new directory(app_name)

The following code is able to save images in pictures directory, but I'm not able to find the perfect way to save image files to the desired app directory using URI.
Edit: The perfect way to store image files to a new directory which can be accessed by other apps is the requirement
SaveActivity.java
final MediaManager mediaManager = new MediaManager(this);
Uri imageURI = mediaManager.GetImageUri();
final ImageView imageHolder = findViewById(R.id.imageHolder);
Glide.with(this).load(imageURI).into(imageHolder);
final String filename = mediaManager.getFileName(imageURI);
save.setOnClickListener(new View.OnClickListener() {#Override public void onClick(View v) {
imageHolder.setDrawingCacheEnabled(true);
Bitmap bitmap = imageHolder.getDrawingCache();
MediaStore.Images.Media.insertImage(getContentResolver(), bitmap, filename, "description");
}
});
MainActivity.java
ImageButton btImgSettings = findViewById(R.id.btnPhoto);
btnPhoto.setOnClickListener(new View.OnClickListener() {#Override public void onClick(View v) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent, 1);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
Uri uri = data.getData();
switch (requestCode){
case 1: if (uri != null) {
String stringUri = uri.toString();
Intent intent = new Intent(this, SaveActivity.class);
intent.putExtra("imageId", stringUri);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NO_ANIMATION);
startActivity(intent);
break;
default:
break;
}
}
}
MediaManager
public class MediaManager {
Activity activity;
public MediaManager(Activity activity) {
this.activity = activity;
}
public Uri GetImageUri() {
Uri imageURI = null;
Bundle bundle = activity.getIntent().getExtras();
if (bundle != null) {
String imageId = bundle.getString("imageId");
imageURI = Uri.parse(imageId);
}
return imageURI;
}
}
Thank you :)
Copy the file to your directory and then use.
Bitmap image= MediaStore.Images.Media.getBitmap(getContentResolver(), data.getData());
File root = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM), "YourDirectory");
if (!root.exists()) root.mkdirs();
String file = root.toString() + File.separator + "FileName" + ".jpg";
try {
FileOutputStream fOutputStream = new FileOutputStream(file);
BufferedOutputStream bos = new BufferedOutputStream(fOutputStream);
image.compress(Bitmap.CompressFormat.JPEG, 100, bos);
fOutputStream.flush();
fOutputStream.close();
} catch (Exception e) {
e.printStackTrace();
}
MediaScannerConnection.scanFile(context, new String[]{file}, null, null);
//This line notifies the system that an image was added and to show it in the gallery.
Hope this helps. Feel free to ask for any clarifications.

Uploading and retrieving image android studio Parse sever

I'm trying to pick multiple images from users gallery and upload (parse server) this images to parse object then retrieve it and set it in an image view
and also i need to pick one image from gallery and save to the users profile
what i have already tried:
//Before OnCreate
String da = "13412412412412414124ASDASDASDASDAD";
////After OnCreate
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
final Uri imageUri = data.getData();
final InputStream imageStream;
try {
imageStream = getContentResolver().openInputStream(imageUri);
final Bitmap selectedImage = BitmapFactory.decodeStream(imageStream);
String encodedImage = encodeImage(selectedImage);
da=encodedImage;
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
private String encodeImage(Bitmap bm) {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.PNG,100,baos);
byte[] b = baos.toByteArray();
String encImage = Base64.encodeToString(b, Base64.DEFAULT);
return encImage;
}
private void ChooseImage() {
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, RESULT_LOAD_IMG);
}
private void CreateThing() {
ParseObject thing = new ParseObject("Things");
thing.put("Image",da);
thing.saveInBackground(new SaveCallback() {
#Override
public void done(ParseException e) {
if (e==null)
Toast.makeText(class.this, "Done", Toast.LENGTH_SHORT).show();
else
Toast.makeText(class.this, e.getMessage(), Toast.LENGTH_SHORT).show();
}
});

Call a Share button Image from another class onCreate method and onActivityResult android

My first question would be, Is onCreate method needed on every new class in android ?
Next, can we use multiple onActivityResult method without causing distortion
?
For exemple my MainActivity and ShareActivity class both have their own onActivityResult and Oncreate method (code taken from git)
MainActivity is for opening camera and gallery
ShareActivity is for sharing images captured
Note : Both class check for permission first
I wanna call the ShareActivity in my MainActivity, the logical thing to do would be
share.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent myIntent = new Intent(MainActivity.this, ShareActivity.class);
startActivity(myIntent);
}
});
But my ShareActivity also has this
#OnClick(R.id.open_share)
void onShareTouched() {
boolean has_perms = EasyPermissions.hasPermissions(ShareActivity.this, perms);
if (has_perms) {
shareImageFromBitmap(this.bmp);
} else {
EasyPermissions.requestPermissions(
ShareActivity.this,
getString(R.string.rationale_storage),
SHARE_STORAGE_PERMS_REQUEST_CODE,
perms);
}
}
And then I thought about calling it like this
ShareActivity.getInstance().onShareTouched();
But the app keep crashing, everytime I call the Share class,
Edit : Should I use implement ?
Note :the Share class works fine without MainActivity (I tried in new project)
for better understanding I leave the complete code below
ShareActivity
public class ShareActivity extends AppCompatActivity {
private static ShareActivity instance;
private static final String TAG = "ShareActivity";
private final int SHARE_STORAGE_PERMS_REQUEST_CODE = 900;
private final int RESULT_LOAD_IMG_REQUEST_CODE = 778;
private final String[] perms = { android.Manifest.permission.WRITE_EXTERNAL_STORAGE, android.Manifest.permission.READ_EXTERNAL_STORAGE};
private static final String IMAGE_URL = null;
private Bitmap bmp;
#BindView(R.id.open_share)
SimpleDraweeView imageView2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ButterKnife.bind(this);
bmp = getBitmapFromUrl(IMAGE_URL);
imageView2.setImageURI(Uri.parse(IMAGE_URL));
instance = this;
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == RESULT_LOAD_IMG_REQUEST_CODE && resultCode == RESULT_OK) {
List<Image> images = ImagePicker.getImages(data);
if(images.size() > 0) {
String imagePath = images.get(0).getPath();
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
bmp = BitmapFactory.decodeFile(imagePath, options);
imageView2.setImageURI(Uri.fromFile(new File(imagePath)));
}
}
}
#OnClick(R.id.open_share)
void onShareTouched() {
boolean has_perms = EasyPermissions.hasPermissions(ShareActivity.this, perms);
if (has_perms) {
shareImageFromBitmap(this.bmp);
} else {
EasyPermissions.requestPermissions(
ShareActivity.this,
getString(R.string.rationale_storage),
SHARE_STORAGE_PERMS_REQUEST_CODE,
perms);
}
}
#AfterPermissionGranted(SHARE_STORAGE_PERMS_REQUEST_CODE)
private void shareImageFromBitmap(Bitmap bmp) {
Uri uri = getUriImageFromBitmap(bmp, ShareActivity.this);
if(uri == null) {
//Show no URI message
return;
}
final Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_TEXT, IMAGE_URL);
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
shareIntent.setType("image/png");
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(Intent.createChooser(shareIntent, "Share image using"));

if (ImagePipelineFactory.getInstance().getMainFileCache().hasKey(cacheKey)) {
BinaryResource resource = ImagePipelineFactory.getInstance().getMainFileCache().getResource(cacheKey);
byte[] data = null;
try {
data = resource.read();
} catch (IOException e) {
e.printStackTrace();
}
return BitmapFactory.decodeByteArray(data, 0, data.length);
}
return null;
}
private Uri getUriImageFromBitmap(Bitmap bmp, Context context) {
if(bmp == null)
return null;
Uri bmpUri = null;
try {
File file = new File(context.getExternalFilesDir(Environment.DIRECTORY_PICTURES), "IMG_" + System.currentTimeMillis() + ".png");
FileOutputStream out = new FileOutputStream(file);
bmp.compress(Bitmap.CompressFormat.PNG, 90, out);
out.flush();
out.close();
bmpUri = FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".provider", file);
} catch (IOException e) {
e.printStackTrace();
}
return bmpUri;
}
public static ShareActivity getInstance() {
return instance;
}
}
MainActivity
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK && data != null) {
if (requestCode == OPEN_THING) {

Bitmap bitmap;
try {
bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
if (uri != null) {
getContentResolver().delete(uri, null, null);
}
scannedImageView.setImageBitmap(bitmap);
FileOutputStream outputStream = null;
File sdCard = Environment.getExternalStorageDirectory();
File directory = new File(sdCard.getAbsolutePath() + "/Scan Documents");
directory.mkdir();
String filename = String.format("d.jpg", System.currentTimeMillis());
File outFile = new File(directory, filename);
Toast.makeText(this, "Image Saved Successfully", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
intent.setData(Uri.fromFile(outFile));
sendBroadcast(intent);
try {
outputStream = new FileOutputStream(outFile);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outputStream);
outputStream.flush();
outputStream.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
I found a better easier way
I had to completely change my method, I put everything in my button onClick
share.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Drawable myDrawable = scannedImageView.getDrawable();
Bitmap bitmap = ((BitmapDrawable)myDrawable).getBitmap();
try{
File file = new File(MainActivity.this.getExternalCacheDir(), "myImage.png");
FileOutputStream fOut = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.PNG, 80, fOut);
fOut.flush();
fOut.close();
file.setReadable(true, false);
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
intent.setType("image/png");
startActivity(Intent.createChooser(intent, "Share Image Via"));
}catch (FileNotFoundException e){
e.printStackTrace();
Toast.makeText(MainActivity.this, "File not found", Toast.LENGTH_SHORT).show();
}catch (IOException e){
e.printStackTrace();
}catch (Exception e){
e.printStackTrace();
}
}
});
No need ShareActivity it works great

I want to save the image in the gallery. It is running but it is showing error on the run time.
Here I am picking the Image from the gallery and want to save that image again in the gallery. Already given the different path to save that picked image.
It is showing
"W/System.err: at >android.app.ActivityThread.main(ActivityThread.java:6692)" while I run the >code.
I already done entry in manifest file.
Your file (or the directory to said file) doesn't exist, you'll need to create the file using createNewFile, something along the following lines should work,
File outFile = new File(directory,filename);
//The below line shouldn't be required since you do directory.mkdir()
//file.getParentFile().mkdirs(); // Will create parent directories if not exists
file.createNewFile(); // Will create file if it doesn't exist
try {
//Rest of your code

Android Saved images are low quality

I'm taking pictures through the following code and saving to SD card, but the pictures that it produces are such low quality and really bitty even with 100% quality. Maybe bitmap.compress isn't the right way to go (or bitmap at all?!)
Heres my code:
public class TakePhoto extends Activity {
ImageView iv;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_take_photo);
iv = (ImageView) findViewById(R.id.imageView1);
Button b = (Button) findViewById(R.id.button1);
b.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, 0);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
Bitmap bm = (Bitmap) data.getExtras().get("data");
Random generator = new Random();
String randFileName = String.valueOf (generator.nextInt(965) + 32);
String both = "/mnt/extSdCard/DirectEnquiries/"+ randFileName + ".jpg";
File imageFile = new File(both);
writeBitmapToMemory(imageFile, bm);
iv.setImageBitmap(bm);
}
public void writeBitmapToMemory(File file, Bitmap bitmap) {
FileOutputStream fos;
try {
Log.e("Tom", "Starting take stream");
fos = new FileOutputStream(file);
Log.e("Tom", "Got stream");
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos);
Log.e("Tom", "Saved Image");
fos.close();
}
catch (FileNotFoundException e) {
e.printStackTrace();
}
catch (IOException e) {
e.printStackTrace();
}
}
}
Please call the below function to capture image from camera.
private final static String FOLDER_NAME = "YourAppName/Image/";
private Uri selectedImageUri = null;
public void startCamera()
{
File photo = null;
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
if (android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED))
{
photo = new File(android.os.Environment.getExternalStorageDirectory(), FOLDER_NAME+File.separator+timeStamp+".png");
}
else
{
photo = new File(getCacheDir(), FOLDER_NAME+File.separator+timeStamp+".png");
}
if (photo != null)
{
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photo));
selectedImageUri = Uri.fromFile(photo);
startActivityForResult(intent, CAPTURE_IMAGE_CALLBACK);
}
}
You can get image Uri in selectedImageUri variable . (Image is stored in Sdcard)
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
switch (requestCode)
{
case CAPTURE_IMAGE_CALLBACK:
break;
}
}
Have you tried setting quality in the intent?
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
startActivityForResult(intent, 0);
