How to pass int value from one activity to another and display in TextView?

Question

I have an integer value in one activity, when I debug I can see there is a value be placed in. The value comes from a counter inside another function within the same class. I am trying to send the variable to another activity and display it in a TextView.

Sending Class:

 Intent intent = new Intent(TrackingActivity.this, StatActivity.class);
            intent.putExtra("yzValue" , getyzVal());
            startActivity(intent);

Receiving Class:

    Intent intent = getIntent();
    baValue = (TextView) findViewById(R.id.baValue);
    String baVal = intent.getStringExtra("yzValue") ;
    maxX.setText(String.valueOf(baVal));

I have tried various solution but it just displays NULL in the TextView.

You need to use getExtra method for int. `getStringExtra` is for String extras — sshashank124, Feb 20 '18 at 13:35
@TejasPandya I have that added,I was using a different setText before posting. Still getting the same result. — JamesD, Feb 20 '18 at 13:39
getyzVal() is an int so putExtra is int and need to get it as int so intent.getIntExtra("key",default_val) or do a cast to explicit type with by get() — ceph3us, Feb 20 '18 at 17:55

Try this,

   String baVal = intent.getExtras().get("yzValue").toString() ;

Correct! Your answer no longer has a negative vote.. ;-) Better 0 than <0. – Taslim Oseni Feb 20 '18 at 17:07
very bad way - oString() Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. You should check assignability then cast ... – ceph3us Feb 20 '18 at 17:57
