I do not see any errors in XML code or in Java Code.
This is my Java Code:
package com.example.simpleinventory;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.text.Editable;
import android.text.TextWatcher;

private ArrayList<String> data1 = new ArrayList<>();
private ArrayList<String> data2 = new ArrayList<>();
private ArrayList<String> data3 = new ArrayList<>();
EditText ed1,ed2,ed3,ed4,ed5,ed6;

}
});
b1.setOnClickListener(new View.OnClickListener() {
@Override

add();
}
});
}
public void add() {

String prodname = ed1.getText().toString();
int price = Integer.parseInt(ed2.getText().toString());
int qty = Integer.parseInt(ed3.getText().toString());
tot = price*qty;
data.add(prodname);
data1.add(String.valueOf(price));

{

String prc = data1.get(i);
String qtyy = data2.get(i);
total = data3.get(i);
t1.setText(pname);
t2.setText(prc);
t3.setText(qtyy);
t4.setText(total);
sum = sum + Integer.parseInt(data3.get(i));
}
row.addView(t1);
row.addView(t2);
row.addView(t3);
row.addView(t4);
table.addView(row);
ed4.setText(String.valueOf(sum));
ed1.setText("");
ed2.setText("");
ed3.setText("");
ed1.requestFocus();
}
}
I'm getting 0 compile errors but I get a runtime error in Logcat.
Here is the error:

you aren't setting your content at all, thus all findViewById are returning null ...
add setContentView method just after super.onCreate call (and before all findViewById s), point on your posted XML file ( R.layout.filename )

This is reported from line 88 in the activity_main.xml file, I see that your textColor is refering to a string, can you verify that this part is correct.
android:textColor="@string/fff"
It should be a color ie :
android:textColor="@color/colorAccent"
Can you post your strings.xml?
