10 個のスピナーと 10 個の編集テキストがあり (ユーザーは複数のスピナーと編集テキストを空白にすることができます)、選択したスピナー オブジェクトの値を合計してテキストを編集するための 2 つのボタンもあります。値を合計することはできますが、アプリを最初に起動したときにリセット ボタンを使用して初期状態に戻すと、問題が発生しました。結果が間違っています。デフォルトに戻したにもかかわらず、最初の操作から値を取得しました。これはリセットボタンの私のコードです
hapus.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
qty1.setText(null);
qty2.setText(null);
qty3.setText(null);
qty4.setText(null);
qty5.setText(null);
qty6.setText(null);
qty7.setText(null);
qty8.setText(null);
qty9.setText(null);
qty10.setText(null);
spin1.setSelection(0);
spin2.setSelection(0);
spin3.setSelection(0);
spin4.setSelection(0);
spin5.setSelection(0);
spin6.setSelection(0);
spin7.setSelection(0);
spin8.setSelection(0);
spin9.setSelection(0);
spin10.setSelection(0);
sum.setText(null);
hasil = 0;
}
});
これは、スピナーと合計操作のコードの一部です
