例えば。

empty は最初の EditText であり、total_empty はもう 1 つの Edit Text です。空の edittext に 1 を入力すると、total_empty edittext に 1 として同時に表示する必要があることを意味します。

その後、私は new.i という EditText を持っており、EditText new の値として 3 を与えます。

その後、上記の 3 つの EditText Values(1+2+3) を追加し、その合計を fill という別の EditText に表示する必要があります。

最後に、total_fill という別の editText があります。ここでも「fill」edittext の上に同じ値を表示する必要があります。

私のコードは以下のとおりです
