Picasso not showing firebase stored image

I'm new to Android Studio and i'm trying to do a simple register and login app, but I have one problem with the Picasso on my "Profile Picture" ImageView where the image is uploaded and stored to firebase, but the stored image won't show on ImageView.
Here's the Upload Photo code

Android Upload Image to Server, write path with text fields to a database and retrieve to list view

Images and Text Uploader
Hallo Coders, i am new in Android. i have the above app to upload images to a server and write the image path to a database alongside the user inputted data as seen in the app UI. So far its uploading only one image with the below code and writing the path as appropriate. I am unable to pass the textview data alongside the image path to a mysql DB. I need the following.
1 Upload multiple images to server and write the images path and the other values to a mysql database.
2. Display the images from the server using the state/county select on a listview (Vertically or Horizontally)
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
public static final String UPLOAD_URL = "http://10.0.2.2/PhotoUpload/upload.php";
public static final String UPLOAD_KEY = "image";
private int PICK_IMAGE_REQUEST = 1;
private Button buttonChoose;
private Button buttonUpload;
private Button buttonView;
private ImageView imageView;
private Bitmap bitmap;
private Uri filePath;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
buttonChoose = (Button) findViewById(R.id.buttonChoose);
buttonUpload = (Button) findViewById(R.id.buttonUpload);
buttonView = (Button) findViewById(R.id.buttonViewImage);
imageView = (ImageView) findViewById(R.id.imageView);
buttonChoose.setOnClickListener(this);
buttonUpload.setOnClickListener(this);
buttonView.setOnClickListener(this);
}
private void showFileChooser() {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
filePath = data.getData();
try {
bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), filePath);
imageView.setImageBitmap(bitmap);
} catch (IOException e) {
e.printStackTrace();
}
}
}
public String getStringImage(Bitmap bmp){
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] imageBytes = baos.toByteArray();
String encodedImage = Base64.encodeToString(imageBytes, Base64.DEFAULT);
return encodedImage;
}
private void uploadImage(){
class UploadImage extends AsyncTask<Bitmap,Void,String>{
ProgressDialog loading;
RequestHandler rh = new RequestHandler();
#Override
protected void onPreExecute() {
super.onPreExecute();
loading = ProgressDialog.show(MainActivity.this, "Uploading...", null,true,true);
}
#Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
loading.dismiss();
Toast.makeText(getApplicationContext(),s,Toast.LENGTH_LONG).show();
}
#Override
protected String doInBackground(Bitmap... params) {
Bitmap bitmap = params[0];
String uploadImage = getStringImage(bitmap);
HashMap<String,String> data = new HashMap<>();
data.put(UPLOAD_KEY, uploadImage);
String result = rh.sendPostRequest(UPLOAD_URL,data);
return result;
}
}
UploadImage ui = new UploadImage();
ui.execute(bitmap);
}
#Override
public void onClick(View v) {
if (v == buttonChoose) {
showFileChooser();
}
if(v == buttonUpload){
uploadImage();
}
if(v == buttonView){
viewImage();
}
}

Finally it worked as required by initialising all aspects in the code.

i want know how Read text from editText and show the answer

I have a question, by pressing long on imageView imageViewClick.setOnLongClickListener recognizes the voice and answers the question. How do I make the normal press imageViewClick.setOnClickListener recognize the text of the editText and answer the question?

}

To recognize the input in EditText and convert the input to speech, you can use the TextToSpeech class provided by Android. Example of this:
textToSpeech = new TextToSpeech(MainActivity.this, MainActivity.this);
editText = (EditText) findViewById(R.id.editText);
imageViewClick = (ImageView) findViewById(R.id.imageViewClick);
imageViewClick.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
TextToSpeechFunction() ;
}});
}
public void TextToSpeechFunction()
{
String text = editText.getText().toString();
textToSpeech.speak(text, TextToSpeech.QUEUE_FLUSH, null);
Toast.makeText(MainActivity.this , text, Toast.LENGTH_LONG).show();
}
#Override
public void onDestroy() {
textToSpeech.shutdown();
super.onDestroy();
}
#Override
public void onInit(int TexttoSpeechCurrentStatus) {
if (TexttoSpeechCurrentStatus == TextToSpeech.SUCCESS) {
textToSpeech.setLanguage(Locale.US);
imageViewClick.setEnabled(true);
TextToSpeechFunction();
}
}

Image from gallery is not displayed on the image button

From the App I should be able to add an image from my gallery to the image button, then add Food name, Description and Price and finally click upload.
The image should be uploaded to my firebase storage while Price,Description and Food name should be uploaded to the firebase database

Can someone explain to me why would this happen and how to fix it?
Thanks a lot :)

you can using this method
public class MainActivity extends AppCompatActivity {
private static final int IMAGE_REQUEST_CODE = 1;
private static final int CAMERA_REQUEST_CODE = 2;
private static final String IMG_FILE_NAME = "tempImg";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// From Gallery
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), IMAGE_REQUEST_CODE);
// Take a Picture
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = Uri.fromFile(GetOutputMediaFile());
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult(intent, CAMERA_REQUEST_CODE);
}
public static File GetOutputMediaFile() {
// External sdcard location
File mediaStorageDir = new File(
Environment.getExternalStorageDirectory() + "/" + HConstants.IMG_FILE_NAME);
// Create the storage directory if it does not exist
if (!mediaStorageDir.exists()) {
if (!mediaStorageDir.mkdirs()) {
return null;
}
}
// Create a media file name
File mediaFile;
mediaFile = new File(mediaStorageDir.getPath() + File.separator
+ IMG_FILE_NAME + ".jpg");
return mediaFile;
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(resultCode == RESULT_OK){
if(requestCode == IMAGE_REQUEST_CODE){
fileUri = data.getData();
Log.i(getClass().getName(), "fileUri" + fileUri);
}else{
Log.i(getClass().getName(), fileUri);
}
}
}
}

Getting Image from Gallery.
Try the following code.Hopefully it will work
public class ImageGalleryDemoActivity extends Activity {
private static int RESULT_LOAD_IMAGE = 1;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button buttonLoadImage = (Button) findViewById(R.id.buttonLoadPicture);
buttonLoadImage.setOnClickListener(new View.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);
}
});
}
#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();
ImageView imageView = (ImageView) findViewById(R.id.imgView);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
}
}

Taking Picture
public class CameraDemoActivity extends Activity {
int TAKE_PHOTO_CODE = 0;
public static int count=0;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//here,we are making a folder named picFolder to store pics taken by the camera using this application
final String dir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES) + "/picFolder/";
File newdir = new File(dir);
newdir.mkdirs();
Button capture = (Button) findViewById(R.id.btnCapture);
capture.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// here,counter will be incremented each time,and the picture taken by camera will be stored as 1.jpg,2.jpg and likewise.
count++;
String file = dir+count+".jpg";
File newfile = new File(file);
try {
newfile.createNewFile();
} catch (IOException e) {}
Uri outputFileUri = Uri.fromFile(newfile);
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(cameraIntent, TAKE_PHOTO_CODE);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == TAKE_PHOTO_CODE && resultCode == RESULT_OK) {
Log.d("CameraDemo", "Pic saved");
}
}
}
Also add the permissions in Manifest File:
<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
