Why am I getting error of 'android.widget.EditText com.google.android.material.textfield.TextInputLayout.getEditText()' on a null object reference

Question

I have seen many forums related to this question but nothing resolved my issue. I hope I get it here.

Here is my Activity Code

public class addIndividual extends AppCompatActivity {
public TextInputLayout individualName;
public TextInputLayout individualPhno;
FirebaseFirestore db;
String name;
String phno;

@Override
protected void onCreate(Bundle savedInstanceState) {
    db=FirebaseFirestore.getInstance();
    individualName  = (TextInputLayout) findViewById(R.id.individualName);
    individualPhno= (TextInputLayout) findViewById(R.id.individualPhno);
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_add_individual);

}


public void submitButton(View view) {
    name= individualName.getEditText().getText().toString();
    phno= "hello";
    Map<String,String> individualInfo = new HashMap<String,String >();
    individualInfo.put("name",name.trim());
    individualInfo.put("phNo",phno.trim());

    db.collection("individuals").add(individualInfo)
            .addOnCompleteListener(new OnCompleteListener<DocumentReference>() {
                @Override
                public void onComplete(@NonNull Task<DocumentReference> task) {

                    Toast.makeText(addIndividual.this, "Inserted Successfully", Toast.LENGTH_SHORT).show();
                }
            });


}
}

I have changed the TextInputLayout to EditText but the problem persists no result Error Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'android.text.Editable android.widget.EditText.getText()' on a null object reference When public EditText individualName;

Error is occurring at name= individualName.getEditText().getText().toString();

**TextInputLayout** not a text holder that you want, add id to **TextInputEditText** and take _text_ from it. — Sky, May 12 '22 at 12:09
Checked out sources of **TextInputLayout** your aproach could work, try to check `individualName != null`. If it _null_ place view binding after setContentView() — Sky, May 12 '22 at 12:15
Getting the same Error Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'android.text.Editable com.google.android.material.textfield.TextInputEditText.getText()' on a null object reference — Vikas vikas, May 12 '22 at 12:16
`super.onCreate(savedInstanceState);setContentView(R.layout.activity_add_individual);` these are your highest priorities, findViewById can't work if you haven't called `setContentView` yet — a_local_nobody, May 12 '22 at 12:17
`setContentView(R.layout.activity_add_individual)` should be first line . You can not find view before setting the content view . SO move it up and super call also and it should work fine . — ADM, May 12 '22 at 12:17

In your onCreate(), you are initialising you view views before setting view. Your onCreate should look like this:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_add_individual);
    db=FirebaseFirestore.getInstance();
    individualName  = (TextInputLayout)findViewById(R.id.individualName);
individualPhno= (TextInputLayout) findViewById(R.id.individualPhno);
}
