    You can auto-fill the inch edit text with a 0 value in onCreate.

    takehtin.setText("0");

    or you can check for

    takehtin.getText().isEmpty()

    if it is empty set the inch value to 0

    Try setting default value in XML file :-

    <EditText
        android:id="@+id/takehtft"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:imeOptions="actionDone"
        android:inputType="number"
        android:text="0"
        android:textColor="@color/black"
        android:textColorHint="@color/black"
        android:textSize="13sp"/>

    Check if edittext’s are empty, then don’t assign any value:

    // By Default, '0'
int hft = 0;
int hin = 0;
if (takehtft.getText().toString() != "") {
    hft = Integer.parseInt(takehtft.getText().toString());
}
if (takehtin.getText().toString() != "") {
    hft = Integer.parseInt(takehtin.getText().toString());
}
Log.d("TAG", "onCreate: Ft:" + hft);
Log.d("TAG", "onCreate: In:" + hin);
