Android add editText proggramatically onClick

Question

so I know the onClick part is quite useless, but just in case it does change anything, ive put it there. so ive got the onClick, and I would like it to add the editText to the current activity, which is called activity_calculation. I currently have this code which I got from another question :

public void addCalc(View view){

EditText myEditText = new EditText(context); // Pass it an Activity or Context
        myEditText.setLayoutParams(new LinearLayoutCompat.LayoutParams(MATCH_PARENT,WRAP_CONTENT)); // Pass two args; must be LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT, or an integer pixel value.
        activity_calculation.addView(myEditText);

    }

any help would be appreciated. maybe you can see what ive done wrong

Why you are creating in onClick.... You Hide the edit text and change visibility during onClick Also... Which might be easy.... You Can Consider That too... If possible — Mukeshkumar S
@MaharithAdityaSS I use onClick because I need the user to add edit texts as much as he needs, its not a set amount, where I can change the visibility, if u understand what I mean...? — Muaaz Kasker

First get a reference to the activity's root layout. To do this add an id attribute to your activity layout file's root layout. eg :

<LinearLayout
    android:id="+id/rootLayout" />

Then, get a reference to it and add the created EditText.

//If your root layout is a RelativeLayout, use that instead
LinearLayout rootView = (LinearLayout) findViewById(R.id.rootLayout);
EditText myEditText = new EditText(rootView.getContext()); 
myEditText.setLayoutParams(new LinearLayoutCompat.LayoutParams(MATCH_PARENT,WRAP_CONTENT)); 
rootView.addView(myEditText);
