using getLayoutInflater().inflate() to get a child element from a layout file in InputMethodService

Question

I am trying to get a Custom keyboardView from layout a file. Here is the code

public class MyInputMethodService extends InputMethodService
        implements KeyboardView.OnKeyboardActionListener {

...
    @Override 
    public View onCreateInputView() {

        SindhikKeyboardView mInputView = (SindhikKeyboardView) getLayoutInflater().inflate(
                                      R.layout.keyboard, null).findViewById(R.id.keyboard);
        mInputView.setOnKeyboardActionListener(this);
        setLatinKeyboard(mQwertyKeyboard);
        return mInputView;
    }
...
}

But it is giving me an error

java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

The code in the layout file:

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

<io.github.fahadmaqsood.sindhik.SindhikKeyboardView
    xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    android:id="@+id/keyboard" />

</RelativeLayout>

I know that .findViewById() is causing the problem. If I remove that and the RelativeLayout element from the layout file, It works! but I want that RelativeLayout to be there... how can I get rid of that error? There are answers similar to the error I got, on this site. but I can't figure out a solution to my problem through them.

Edit: Full error log

can you post more of logcat and highlight the lines where actually the error is — Abhinav Chauhan, Mar 03 '20 at 11:19

No, it didn't help. and no matter where ever I use removeView() it always says "the method removeView() is not resolved." and I think my problem is different than the one in that question. I am not appending anything I am just getting something through findViewById() — Fahad Maqsood Qazi, Mar 04 '20 at 12:21
