Sending all the value from Listview A to B

In Activity A, I have a listView and an action bar icon used to intent to Activity B. If listView is pressed, it will send all the value from A to B and display on editText. 

 listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            public void onItemClick(AdapterView<?> listView, View view, final int position, long id) {
                Expenses o = (Expenses) obj.getItem(position);
                String day = o.getDate(); // 4 Dec 2016
                String[] split = day.split("\\s+");
                String date= split[1]; // 4 
                Intent intent = new Intent(QuickExpenses.this,AddExpenses.class);
                intent.putExtra("date",date);
                intent.putExtra("month", month); // Dec 2016
                startActivity(intent);
            }
        });

 @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {

            case R.id.action_add_task:
                Intent intent = new Intent(QuickExpenses.this, AddExpenses.class);
                intent.putExtra("month", month); // Dec 2016
                startActivityForResult(intent, PROJECT_REQUEST_CODE);
                return true;
            }
         }

Activity B

Activity B has an editText. When editText is pressed it will pop out datePickerDialog, for user select the date. 

EditText date;
String month;

date = (EditText) findViewById(R.id.date);
month = getIntent().getStringExtra("month");

 if(getIntent().getExtras()!=null) { //if  has value pass from A (listView pressed)
            String mDay = getIntent().getExtras().getString("date");
            date.setText(mDay + "" + month);
        }

So if the listview is pressed, it will display 5 Dec 2016 in EditText date. But the problem is when I click the icon in Activity A, it display null Dec 2016 . I want to clear the editText by using date.setText("") and date.getText().clear(); but it still showing null Dec 2016.

I want date editText display nothing if icon Activity A pressed but not null Dec 2016.

You must check the intent from listview or icon.From your code can check from mDay is empty or not.If mDay is empty it's form icon pressed.

if(getIntent().getExtras()!=null) { 
      String month = getIntent().getStringExtra("month");
      String mDay = getIntent().getExtras().getString("date");
      if(!TextUtils.isEmpty(mDay)
          date.setText(mDay + "" + month);
      else // mDay will empty from icon click.
          date.setText("");

 }

Check below code : 

    if(getIntent().getExtras()!=null) { //if  has value pass from A (listView pressed)
                String mDay = getIntent().getStringExtra("date");
    if(!TextUtils.isEmpty(mDay) && !TextUtils.isEmpty(month)){
date.setText(mDay + "" + month);
    }

            }

The problem with your code is your passing intent in both cases so that is why it is going inside this block

 if(getIntent().getExtras()!=null) { //if  has value pass from A (listView pressed)
            String mDay = getIntent().getExtras().getString("date");
            date.setText(mDay + "" + month);
        }

so just change your if condition with below code

 if(getIntent().getExtras().getString("date")!=null) { //if  has value pass from A (listView pressed)
            String mDay = getIntent().getExtras().getString("date");
            date.setText(mDay + "" + month);
        }
  else {
            date.setText("");
      }

Hope this will help

Based on your Code , some value (Variable month,ie may be holding the value Dec 2016) is send using intent when you are clicking on the icon in Action bar

remove

intent.putExtra("month", month); // Dec 2016

from onOptionsItemSelected

Try out the following snippet!

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {

        case R.id.action_add_task:
            Intent intent = new Intent(QuickExpenses.this, AddExpenses.class);
            intent.putExtra("date", ""); // Dec 2016
            intent.putExtra("month", month); // Dec 2016
            startActivityForResult(intent, PROJECT_REQUEST_CODE);
            return true;
    }
}

Hope this help you!
