When android emulator runs it shows blank screen

When android emulator runs it shows blank screen - java

I created an activity to edit some data by clicking the edit button it will send the key of it to another activity. All of my activity works normally except this particular one that does not show anything other than blank screen.
These are my codes where the problem occured.

DatePickerDialog issue with fragments

I have a fragment with editText that is meant to open a date picker. I have done everything seemingly correctly, however I can't figure out why I get the following error.
It has something to do with the fact that I'm working with a fragment.
Could you please help with this error?

//EditText
mDisplayDate = view.findViewById(R.id.etDateOfBirth);

mDisplayDate.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Calendar cal = Calendar.getInstance();
int year = cal.get(Calendar.YEAR);
int month = cal.get(Calendar.MONTH);
int day = cal.get(Calendar.DAY_OF_MONTH);
DatePickerDialog dialog = new DatePickerDialog(
requireContext(),
android.R.style.Theme_DeviceDefault_Dialog_MinWidth,
mDateSetListener,
year, month, day);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
dialog.show();
}
});
mDateSetListener = new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker datePicker, int year, int month, int day) {
month = month + 1;
String date = month + "/" + day + "/" + year;
mDisplayDate.setText(date);
}
};
return view;
}
}

It just tells you that the first parameter of the DatePickerDialog constructor is not as supposed to be; where you put a Fragment, while it expects a context, so replace below line
DatePickerDialog dialog = new DatePickerDialog(
EditProfileFragment.this,
android.R.style.Theme_DeviceDefault_Dialog_MinWidth,
mDateSetListener,
year, month, day);
with
DatePickerDialog dialog = new DatePickerDialog(
requireContext(),
android.R.style.Theme_DeviceDefault_Dialog_MinWidth,
mDateSetListener,
year, month, day);

Use getapplicationcontext() and remove Edittextprofilefragment.this

Use startActivityForResult() to get the result from another activity.
By the help of android startActivityForResult() method, we can send information from one activity to another and vice-versa.
Intent intent=new Intent(this,Class2.class);
startActivityForResult(intent,10);

Why the imageView which is in "userProfilePic" id, changes quickly to the old one stored in database, after selecting a new picture [closed]

Improve this question
I want to change the picture in the imageView id "userProfilePic" to the new one selected by the user, and update that picture to the database. But once I choose a new picture, the image under "userProfilePic" id quickly changes to the new one and again it changes to the old one( which is already in the database) so I am unable to upload new pictures for the "userProfilePic" id. I am a beginner to Android development and I know only small amount of android, So please help me to solve this issue. This is my EditUserProfile.java file

I think it may come from the fact that you call showDetail on you onstart method which is called when you come back to your activity. Maybe it does something like that:
activityToPickUpAPic-->PickUpAPic-->Go back to that activity-->
Onstart-->May start to download your image->start on activity result-> charge your new image->finish to download your image from the server
When you come back to your activity onStart is called again so you may want to change this method and call the download picture just at the Oncreate method.
Let me know it that's the problem ;)
Edit:
boolean isImageSet = false;
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==Result_Load_Image && resultCode==RESULT_OK && data!=null){
Uri selectedImage= data.getData();
userProfilePic.setImageURI(selectedImage);
isImageSet = true;
}
}
and:
if(bitmap!=null && !isImageSet){
userProfilePic.setImageBitmap(bitmap);
}
For the Test you could just comment
//userProfilePic.setImageBitmap(bitmap);

At the moment you are executing calculate() in the MainActivity.java second activity called ResultPage doesn't exist, therefore you can't change it's view (editText3and editText4).
In order to pass data to another activity you should fill your Intent with some extra data and then in your ResultPage activity's onCreate you would get underlying extras.
EDIT
MainActivity.java
public void gotoactivity (View v) {
calculate();
Intent intent = new Intent(this, ResultPage.class);
intent.putExtra("AMOUNT_3", y);
intent.putExtra("AMOUNT_4", z);
startActivity(intent);
}
ResultPage.java inside onCreate
Bundle extras = getIntent().getExtras();
if (extras != null) {
int amount3 = extras.getInt("AMOUNT_3");
int amount4 = extras.getInt("AMOUNT_4");
}
