dismiss() method of Progress dialog is not working - android

May be same question is encountered to you before, I am sorry for that but I really need to ask this.I am trying to show Progress dialog and then dismissing it But I am not able to do it. I have searched a lot and tried many ways but cant really get through. I am uploading images after picking from gallery. and during upload i want to show the dialog and after uploading dialog should be dismissed here is my code.
public class FaceActivity extends Activity {
private static int RESULT_LOAD_IMAGE = 1;
private Button upbtn;
public Bitmap bm;
public ByteArrayOutputStream bos;
public byte[] bitmapdata;
public String picturePath;
private ProgressDialog pd;
private BitmapFactory.Options options;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_face);
//pd = new ProgressDialog(FaceActivity.this);
upbtn = (Button) findViewById(R.id.buttonLoadPicture);
upbtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent i = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
picturePath = cursor.getString(columnIndex);
cursor.close();
options = new BitmapFactory.Options();
// will results in a much smaller image than the original
options.inSampleSize = 8;
upload();
}
}
public void upload(){
// Here I am showing the dialog
pd = ProgressDialog.show(FaceActivity.this, "Please Wait", "Loading...", true, false);
bm = BitmapFactory.decodeFile(picturePath);
bos = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.JPEG, 40 , bos);
bitmapdata = bos.toByteArray();
ParseFile file = new ParseFile("pic.jpg", bitmapdata);
file.saveInBackground();
ParseObject po = new ParseObject("Images");
po.put("Images", file);
po.saveInBackground();
ImageView imageView = (ImageView) findViewById(R.id.targetimage);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath,options));
// want to dismiss dialog here
pd.dismiss();
Toast.makeText(this, "Image Uploaded Successfully", Toast.LENGTH_LONG).show();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_face, menu);
return true;
}
}

try to do that in asyc task.
private class asynUpload extends AsyncTask<String, Void, Integer> {
protected Integer doInBackground(String... params) {
try {
runOnUiThread(new Runnable() {
public void run() {
pd = ProgressDialog.show(FaceActivity.this, "Please Wait", "Loading...", true, false);
}
});
bm = BitmapFactory.decodeFile(picturePath);
bos = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.JPEG, 40 , bos);
bitmapdata = bos.toByteArray();
ParseFile file = new ParseFile("pic.jpg", bitmapdata);
file.saveInBackground();
ParseObject po = new ParseObject("Images");
po.put("Images", file);
po.saveInBackground();
ImageView imageView = (ImageView) findViewById(R.id.targetimage);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath,options));
} catch (Exception e) {
return 0;
}
return 1;
}
protected void onPostExecute(Integer result) {
try {
runOnUiThread(new Runnable() {
public void run() {
pd.dismiss();
}
});
} catch (Exception e) {}
super.onPostExecute(result);
}
}

protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data)
{
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
picturePath = cursor.getString(columnIndex);
cursor.close();
options = new BitmapFactory.Options();
// will results in a much smaller image than the original
options.inSampleSize = 8;
// use the task here
new asynUpload().execute();
}
}

You can look here for the idea you've been looking for implementing a background process: doInBackground not working in Android fragment

Selected Gallery image not showing in imageview

I was selected the image after it have to set it in the imageview.But it doesn't set it in imageview.
I have posted the relevant code.

I dont know why selected image not showing in imageview.Anyone can help me with this.Thank you.
I Have use this code:
private void openGallery() {
Intent gallery =
new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI);
startActivityForResult(gallery, PICK_IMAGE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK && requestCode == PICK_IMAGE) {
Uri imageUri = data.getData();
try {
bitmaps = MediaStore.Images.Media.getBitmap(this.getContentResolver(), imageUri);
final ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmaps.compress(Bitmap.CompressFormat.PNG, 90, stream);
byte[] byteArray = stream.toByteArray();
encodeded = Base64.encodeToString(byteArray, Base64.DEFAULT);
byte[] decodedString = Base64.decode(encodeded, Base64.DEFAULT);
Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);
userinfoimage.setImageBitmap(bitmaps);
new UploadImage().execute();
} catch (IOException e) {
e.printStackTrace();
}
}
}
If you only want to set image in imageview. you can directly use the uri. Like this
String stringUri = selectedImageUri.getPath();
galImageView.setImageURI(null);
galImageView.setImageURI(Uri.parse(stringUri));

Use the below code for opening in the image gallery.
Intent browseIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(browseIntent, RESULT_LOAD_IMAGE);
and below code for pick the image from gallery.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
imagePath = cursor.getString(columnIndex);
cursor.close();
try {
byte[] b;
Log.d("picture", imagePath);
bm = BitmapFactory.decodeFile(imagePath);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.JPEG, 100, baos); //bm is the bitmap object
b = baos.toByteArray();
encodedImageToBase64 = Base64.encodeToString(b, Base64.DEFAULT);
} catch (Exception e) {
e.printStackTrace();
}
index = imagePath.lastIndexOf("/");
attachmentImageName = imagePath.substring(index + 1);
}
}
may this will help you.
you can use the below code. it works for me.

Instead of trying it by yourself, take a look at recent-images library. It can help you. here is the link.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// find the views
image = (ImageView) findViewById(R.id.uploadImage);
uploadButton = (Button) findViewById(R.id.uploadButton);
// on click select an image
selectImageButton = (Button) findViewById(R.id.selectImageButton);
selectImageButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
selectImageFromGallery();
}
});
}
public void selectImageFromGallery() {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"),
PICK_IMAGE);
}
/**

Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
cursor.moveToFirst();
String picturePath = cursor.getString(columnIndex);
cursor.close();
decodeFile(picturePath);
}
}
/**
* The method decodes the image file to avoid out of memory issues. Sets the
* selected image in to the ImageView.
*
* #param filePath
*/
public void decodeFile(String filePath) {
// Decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeFile(filePath, o);
// The new size we want to scale to
final int REQUIRED_SIZE = 1024;
// Find the correct scale value. It should be the power of 2.
int width_tmp = o.outWidth, height_tmp = o.outHeight;
int scale = 1;
while (true) {
if (width_tmp < REQUIRED_SIZE && height_tmp < REQUIRED_SIZE)
break;
width_tmp /= 2;
height_tmp /= 2;
scale *= 2;
}
// Decode with inSampleSize
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize = scale;
bitmap = BitmapFactory.decodeFile(filePath, o2);
image.setImageBitmap(bitmap);
}
Here is the complete code. But still getting error on cursor. In besides, here used contentResolver query stuff.What I think I should add some extra code for that.Can someone tell me about contentResolver and my problem
Try this...
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE);

About loading animations in Android

I'm using the image picking intent to get an image from the user's gallery and put it in an ImageView after I compress it.
It takes about 2 seconds on my device but it will most likely take more or less time on other devices. I was wondering how I can set a loading animation that would last for exactly the time needed to load the image (so not a pre-set duration) in the ImageView?
Here is the code where I handle the image. Everything works, I just don't know how to use the loading animation for this:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
File file = new File(picturePath);
picturePath = file.getAbsolutePath();
Bitmap bitmap = BitmapFactory.decodeFile(picturePath);
Bitmap bitmapRotated = rotateBitmap(bitmap, picturePath);
if(bitmapRotated != null)
bitmap = bitmapRotated;
imageToSave = Bitmap.createScaledBitmap(bitmap, image.getWidth(), image.getHeight(), false);
image.setImageBitmap(imageToSave);
thumbnailToSave = image.getThumbnail();
space.setVisibility(View.GONE);
edit.setVisibility(View.VISIBLE);
save.setVisibility(View.GONE);
image.setEditing(false);
imageChanged = true;
thumbnailChanged = true;
image.invalidate();
}
}
You should use Android progress bar.
You can create a bar that represents how far the operation is going to take or just a spinning wheel.
You need to create a thread for your task and another thread for updating the progress bar.
public class MyAndroidAppActivity extends Activity {
Button btnStartProgress;
ProgressDialog progressBar;
private int progressBarStatus = 0;
private Handler progressBarHandler = new Handler();
private long fileSize = 0;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
addListenerOnButton();
}
public void addListenerOnButton() {
btnStartProgress = (Button) findViewById(R.id.btnStartProgress);
btnStartProgress.setOnClickListener(
new OnClickListener() {
#Override
public void onClick(View v) {
// prepare for a progress bar dialog
progressBar = new ProgressDialog(v.getContext());
progressBar.setCancelable(true);
progressBar.setMessage("File downloading ...");
progressBar.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
progressBar.setProgress(0);
progressBar.setMax(100);
progressBar.show();
//reset progress bar status
progressBarStatus = 0;
//reset filesize
fileSize = 0;
new Thread(new Runnable() {
public void run() {
while (progressBarStatus < 100) {
// process some tasks
progressBarStatus = doSomeTasks();
// your computer is too fast, sleep 1 second
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
// Update the progress bar
progressBarHandler.post(new Runnable() {
public void run() {
progressBar.setProgress(progressBarStatus);
}
});
}
// ok, file is downloaded,
if (progressBarStatus >= 100) {
// sleep 2 seconds, so that you can see the 100%
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
// close the progress bar dialog
progressBar.dismiss();
}
}
}).start();
}
});
}
// file download simulator... a really simple
public int doSomeTasks() {
while (fileSize <= 1000000) {
fileSize++;
if (fileSize == 100000) {
return 10;
} else if (fileSize == 200000) {
return 20;
} else if (fileSize == 300000) {
return 30;
}
// ...add your own
}
return 100;
}
}
Here is my solution with a ProgressDialog, using the same code.
#Override
protected void onActivityResult(int requestCode, int resultCode, final Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
final ProgressDialog progress = new ProgressDialog(this);
progress.setMessage(getResources().getString(R.string.loading));
progress.show();
Thread mThread = new Thread() {
#Override
public void run() {
Uri selectedImage = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
File file = new File(picturePath);
picturePath = file.getAbsolutePath();
Bitmap bitmap = BitmapFactory.decodeFile(picturePath);
Bitmap bitmapRotated = rotateBitmap(bitmap, picturePath);
if(bitmapRotated != null)
bitmap = bitmapRotated;
imageToSave = Bitmap.createScaledBitmap(bitmap, image.getWidth(), image.getHeight(), false);
thumbnailToSave = image.getThumbnail();
imageChanged = true;
thumbnailChanged = true;
PictureActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
image.setEditing(false);
space.setVisibility(View.GONE);
edit.setVisibility(View.VISIBLE);
save.setVisibility(View.GONE);
image.setImageBitmap(imageToSave);
image.invalidate();
}
});
progress.dismiss();
}
};
mThread.start();
}
}

i'm so fustrated from this little thing that for some reason just doesn't work out...i don't really know what else to do. the pictures im trying to add are been selected by my gallery..(the last thing i've checked was 1024X768 and 32 color bit)
