Getting data in intent giving error in only one activity

Getting data in intent giving error in only one activity - java

I'm trying to pass an intent from adapter and get it in my activity.
Whenever I did this it went to the else condition.
It doesn't get the value and I don't no why. When I try the same code in any other activity it worked perfectly, but in this activity it always gives a null value in intent.
I know there are so many answers to how to get and pass intent, but in my case it doesn't work in one activity and I don't know why.
My Adapter class:
holder.getSurvey.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(context,AuthorMainScreen.class);
intent.putExtra("work", "getting");
context.startActivity(intent);
}
My AuthorMainScreen Activity:

Do you have another class with the same class name, but different package name?
Because it seems like there is no extra parameter present in your receiver activity (AuthorMainScreen). Sometimes mistakes like this can take more time than any other logical mistake. Or you can try to call it onCreate() by commenting the rest of the code. Just check this.

Mistake is here that you called finish(); before calling startActivity(MainIntent);. Use camelCaseinstade of Capital case in defining variable.
Make changes in your emailloginActivity as below
// changed from MainIntent to mIntent.
private void SendUserToMain() {
String userName = mAuth.getCurrentUser().getUid();
Intent mIntent = new Intent(emailloginActivity.this, MainActivity.class);
mIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
mIntent.putExtra("mUserID" , userName );
startActivity(mIntent);
finish();

Item duplicated in RecyclerView after application call onStart

Every time the application is destroyed and opened again, by another mean every time the method "onStart" is called, every new item added two times.
And when I close it and open it again, every new item will be repeated three times , and so on...

I appreciate your help as I can't figure out the problem. Please note that a lot of functions have been removed for readability.

To resolve your issue, clear adap zter while loading new data, so duplicacy can be removed and update new data. This issue occur due to multiple call on Android Lifecycle method in various state like
onResume - Called multiple times. So avoid initalization in here
onStart - is called whenever application is come from background to foreground or visible state
// When adding new data
adapter.addAll(data);
adapter.notifyDataSetChanged();
// when updating data again in onResume or onStart
adapter.clear();// clear old data from list
adapter.addAll(data);
adapter.notifyDataSetChanged();
//Inside adapter
//Adding item
void addAll(List<Data> data){
list.addAll(data);
}
//For clearing list
void clear(){
list.clear();
// To update list automatically add below line
//notifyDataSetChanged();
}

Multiple layout setVisibility wont show correct layout after getting pressed on certain layout

I have a layout in which there are several other layouts by including in XML, I add some textviews as buttons to change the view layouts from one layout to another.
I display each layout with the setVisibility method between layouts, with setOnClickListener in the textview.
The problem is just after finishing displaying the "profile" layout and trying to display the "about us" layout, the system displays a "profile" layout instead of the "about us" layout.
Here is myJava

solved by using setContentView rather than setVisibility.

App is not responding after running this activity

New Activity UI load but does not respond, After running onStop() which trigger submit()
List View with the checkbox is bound by a custom adapter. On touch of the Submit button, an intent is triggered which takes me to HomeActivity and onStop() method is triggered which in return call submit method. All submit method is created under a new thread which interfere with UI.

Just use

and remove finish()

Call number when click list view item

I have a contact list activity but want to add some functionality so that when you click on a contact it will begin calling their phone number. I have tried this code snippet but nothing happens when I tap on a contact:
view.setOnClickListener(new View.OnClickListener() {

try{

Have you try this code??
Uri number = Uri.parse("tel:123456789");
Intent callIntent = new Intent(Intent.ACTION_DIAL, number);
startActivity(callIntent);
